= Difference between Debug Firmware HV and Retail HV =

There is no difference between debug firmware lv1.self and retail firmware lv1.self
The differences reside on the repository nodes loaded because of policies/flags.

= HSPRG  =

*The hypervisor stores a pointer to some structures per LPAR in HSPRG0 register. 
*'''There are actually 2 HSPRG0 values: one for each thread of Cell CPU'''&nbsp;!!! 
*There is a HSPRG0 array at 0x8(-0x69A0(HSPRG0)) + 0x20.

= LPAR  =

LPAR = Logical Partition 

lpar1 starts at 0x&lt;unknown&gt;, and it's believed to be the memory space where lv1 stores its variables, flags and other data. 

lpar2 starts at 0x80000000000 and it's believed to be the memory space where lv2 stores its variables, flags and other data.

== Storage device class  ==

=== Member variables  ===

offset 0x8 - device id (8 bytes) 

offset 0xD50 - device id (8 bytes) 

offset 0xD60 - pointer to ENCDEC SB bus device object 

=== Region Manager ===

* Each storage device has a Region Manager (i call it like that)
* Region Manager stores information about each Region of the storage device
* All Regions of a Region Manager are linked together
* Free Regions of a Region Manager are linked together also
* A Region Manager can have at most 8 Regions

==== Region ====

*Each storage device can have at most 8 regions (0-7) 
*Each region has ACL table
*HV checks region ACLs before allowing access to the region
*Each region has a start sector that is an offset from the physical first sector of the storage device and a number of sectors 

*The start sector passed to lv1 storage hvcalls is '''relative''' to the start sector of the region passed to the lv1 storage hvcall

===== Region ACL =====

offset 0x0 - LPAR AUTH ID (8 bytes)

offset 0x8 - access rigths (8 bytes)

offset 0x10 - entry valid flag: 0 - invalid, 1 - valid (1 byte)

===== Region Access Protection =====

*Before a storage region is accessed, HV checks access rights of the caller. 
*Repository node '''ss.laid''' ([[Authority ID|LPAR Authority ID]]) is evaluated for this purpose. 
*If LPAR has a repository node '''ios.ata.region0.access''' (value doesn't matter) then the access rights check never fails. After System Manager sets ATA keys it removes this repository node from LPAR 1. If we add this repository node again or patch System Manager so it's not removed then we will be able to access all storage regions of all storage devices.
*'''ALL storage accesses from LPAR 1 are allowed''' 
*'''If (flags &amp; 0x100000002)&nbsp;!= 0 then access rights check is skipped&nbsp;!!!'''.

  I tested on HV 3.41 with flags 0x2 and got access to regions which were denied by policy (LV1_DENIED_BY_POLICY result).

== Storage subsystem device  ==

device id = -1 

*The storage subsystem is a storage device itself. 
*It's a pseudo device used to notify a LPAR when storage devices become e.g. ready. 
*Linux implements a loop and reads from this device and process notifications (adds new devices dynamically).

=== Notification Events  ===

List of supported notification events: 

*Notify Device Ready (0x1) 
*Notify Region Probe (0x2) 
*Notify Region Update (0x4)

== RBD device  ==

*On Linux, ENCDEC and RBD devices are mapped to the storage device with device id 0.
*On GameOS, ENCDEC device has device id 0 and RBD device has device id 2.

==== EdecKgen2 Command (0x82) ====

*The base address of MMIO registers used in this command is '''0x24003006000'''.

==== EdecKset Command (0x83) ====

==== EdecKgenFlash Command (0x84) ====

*The base address of MMIO registers used in this command is '''0x24003006000'''.
*The command reads 4 bytes from address '''0x240030060A0''', sets bit 1 to 1 (old value | 0x2) and writes the new value to the same address.

==== Encdec decsec Command (0x86) ====

*This command is used to decrypt/encrypt sectors.
*FLASH, HDD and RBD storage devices use this command to decrypt/encrypt sectors.
*This command cannot be executed through lv1_storage_send_device_command HV call, it's used by HV only internally.

==== EdecSBClear Command (0x87) ====

*The command expects arg2 to be 4 or else it returns with an error.
*This command is used e.g. by '''Storage Manager service 0x5002''' when ATA keys are deleted.

=== Test Mode ===

* ENCDEC device has '''Test Mode'''
* Some HV functions test it by reading a 4 byte value from address '''0x24003005200'''. If this value is 0 then ENCDEC device is NOT in '''Test Mode'''.

=== ENCDEC Request ===

offset 0x34 - start sector (4 bytes)

offset 0x38 - sector count (4 bytes)

offset 0x3C - sector size (4 bytes)

offset 0x40 - key (4 bytes)

offset 0x44 - 0 = decrypt, 1 = encrypt (4 bytes)

=== Encrypting and Decrypting Sectors ===

*HV passes to ENCDEC device addresses of 2 buffers: '''ENCDEC User Buffer''' and '''ENCDEC Descriptor Buffer'''.
*'''ENCDEC User Buffer''' contains the following information: '''Start Sector''', '''Sector Count''', '''Sector Size''' and '''Key'''

==== ENCDEC User Buffer ====

offset 0x0 - start sector (4 bytes)

offset 0x4 - sector count (4 bytes)

offset 0x8 - sector size (4 bytes)

offset 0xC - key (4 bytes)

== FLASH device  ==

device id = 1 

*The FLASH device uses ENCDEC device.

=== vtable  ===

0x00354450 (3.15) 

=== Member variables ===

offset 0x18F0 - request table (0x58 * 16 bytes)

=== Supported Device Commands  ===

Here is the list of commands supported by FLASH StarShip 2 storage device. 

*The commands can be used with HV call '''lv1_storage_send_device_command'''. 
*However, before a command is executed HV does bit manipulation with it and checks it against the value of repository node '''ss.laid''' or also called '''[[Authority ID|LPAR Authority ID]]'''. If this test fails then the command is NOT executed.

=== /dev/eflash1 and /dev/rflash1  ===

*These LPAR 1 devices access region 0 of FLASH storage device. 
*/dev/rflash1 is 16MB large 
*There is no file system on /dev/rflash1 
*There is some sort of TOC (Table Of Contents) stored in it. It contains file names, offsets and sizes. 
*On /dev/rflash1 you will find '''lv0''', '''lv1ldr''', '''lv2_lernel.self''' and all the other important SELFs. 
*The files are encryted of course.

==== Content of /dev/rflash1 (FLASH storage device region 0, size 16 MB)  ====

*There is a main TOC which describes different regions on '''/dev/rflash1''' 
*It seems that TOC 0xC0000 and TOC 0x7C0000 contain the same files but from different SDK versions. 
*TOC 0xC0000 is SDK version 3.41 and TOC 0x7C0000 is SDK version 3.30 (look at the content of files '''sdk_version'''). 
*I guess it's because when i bought my PS 3 Slim it had Firmware 3.30 and i updated it to 3.41 for PSGroove. 
*TOC on '''/dev/rflash1''' is used by HV Processes to locate files and load them into memory, e.g. SPU modules. E.g. Process 6 loads '''spu_utoken_processor.self''' to decrypt and verify user tokens or SPL which runs in Process 5 loads '''spp_verifier.self''' from there in order to decrypt and verify profile files. And Update Manager stores e.g. there files.

===== TOC Entry  =====

A TOC entry is 0x30 bytes large. 

offset 0x0 - relative offset from this TOC to entry data 

offset 0x8 - entry data size 

offset 0x10 - entry name (max 32 characters)

=== /dev/rflash1_1x and /dev/rflash_1xp  ===

*These LPAR 1 devices access region 5 of UNKNOWN storage device. 
*In region 5 of UNKNOWN storage device is e.g. LINUX image stored.

=== GameOS's dev_flash ===

*dev_flash has '''FAT16''' file system.
*Accesses to GameOS's dev_flash are routed to '''UNKNOWN storage device region 2'''
*To decrypt sectors read from this region use as '''flags 0x4''' !!! Without using '''flags 0x4''' the sectors will be encrypted.
*The sectors are decrypted not by GameOS but by ENCDEC device.

Here is a snippet from raw '''dev_flash''' dump made with HV call '''lv1_storage_read (flags 0x4)''' from GameOS:

== Enqueueing and Scheduling of Storage Requests ==

*HV uses a simple '''FIFO''' scheduling algorithm for Storage Requests and a request timeout.
*Each storage device has a table of size '''16''' to store incomming and pending Storage Requests
*ENCDEC storage device has a table of size '''32''' to store incomming and pending Storage Requests
*When a new Storage Request is submitted e.g. by HV call '''lv1_storage_read''' or '''lv1_storage_write''', the table is scanned for a free slot, if there are no pending Storage Requests then the Storage Request is executed immediately
*When a Storage Request is completed, the finished Storage Reuqest is passed to function '''storage_device_async_request_complete''' and the table of Storage Requests is scanned again for the next pending Storage Request which will be executed
* There are 2 types of Storage Requests: '''Read/Write (1)''' and '''Device Command (2)'''.
* Read and Write Storage Requests use the same HV function of a Storage Device to enqueue the request. Before Write Storage Request is inserted into the Request Table of a Storage Device, the '''flags''' parameter passed e.g. in '''lv1_storage_read''' or '''lv1_storage_write''' is '''ored''' with '''0x8'''. That is how HV differentiates between Read and Write Storage Requests.

=== Storage Device Request Table ===

*Each request slot is of size '''0x58'''

==== Request Slot ====

offset 0x0 - state: 1 - free, 2 - ? (4 bytes)

offset 0x4 - type: 1 - Read/Write, 2 - Command, 0x86 - ENCDEC command (4 bytes)

offset 0x10 - request tag (8 bytes)

offset 0x20 - start sector (8 bytes)

offset 0x28 - sector count (4 bytes)

==== ENCDEC Storage Device ====

*Request Table begins at '''offset 0xDC0''' of ENCDEC storage device.

==== RBD Storage Device ====

*Request Table begins at '''offset 0x1808''' of RBD storage device.

==== FLASH Storage Device ====

*Request Table begins at '''offset 0x18F0''' of FLASH storage device.

==== HDD Storage Device ====

*Request Table begins at '''offset 0x17E8''' of HDD storage device.

== Encryption and Decryption of Storage Devices ==

=== HDD ===

*'''ENCDEC peripheral device''' is used for HDD encryption/decryption
*Write request is first passed to ENCDEC device for encryption. When ENCDEC device is done, it calls a callback and passes the encrypted data to the callback. The callback writes the encrypted data with '''ATA WriteDMAExt''' command to HDD.
*When a storage device request is processed by HV, Storage Subsystem checks if cryptography is enabled for the storage device.
*HV checks 1 byte of data owned by the storage device and when the value of this flag is '''not 0''' then it uses encryption/decryption.
*'''By setting this flag to 0 at runtime, encryption/decryption of storage devices can be disabled at runtime'''.
*'''We could patch lv1.self so that encryption/decryption of storage devices is disabled permanently'''.
*HDD sectors can be both decrypted and encrypted with HV calls

==== UFS2 ====

*'''Superblock''' starts at '''sector 0x80'''.
*At the end of the superblock structure you will find '''UFS2 signature 0x19540119'''.

Here is the decrypted '''superblock''' of UFS2 filesystem:

= SPE  =

There are 3 SPE classes. 

The HV call '''lv1_construct_logical_spe''' can create LogicalSPE, SPEType1 and SPEType2 objects. 

The '''syscall 0x10040''' creates only SPEType1 objects. 

The SPEType1 and SPEType2 objects cannot be created when isolation mode is disabled. The right most bit of repository node '''sys.lv1.iso_enbl''' is checked and when it's not 1 then the SPEType1 and SPEType2 objects cannot be created. In LPAR 1, this check succeedes always. Only in LPARs different from 1, the repository node '''sys.lv1.iso_enbl''' is checked. 

== LogicalSPE  ==

SPE type = 0 

Objects of this class are used e.g. on Linux. 

=== vtable  ===

0x00358360 (3.15) 

offset 0x20 - pointer to TOC entry of interrupt handler for SPE

== SPE Register Shadow Area  ==

*HV createas a SPE Register Shadow Area for each contstructed SPE. 
*The area is 1 4Kb page of physical memory. 
*When SPE state changes then HV updates data in this area. 
*The value of '''shadow_addr''' that is returned by '''lv1_construct_logical_spe''' is a LPAR start address of this area and it cannot be accessed until it's mapped in the HTAB. 
*The SPE Register Shadow Area may be mapped only with read-only page protection or else HV call '''lv1_insert_htab_entry''' fails. I tested it with PSGroove and could map the whole memory range and read it after i constructed SPE of type 1 with '''lv1_construct_logical_spe'''. 
*The shadow_addr is also returned by '''syscall_10040''' (that creates SPE of type 1) but it returns already mapped Process address so HV Processes do not have to map it in HTAB. 
*When an isoated SPU is done, HV Processes checks the value at offset 0x30 to determine if the SPU execution was successfull or not. 
*GameOS checks also the value at offset 0x30 in the SPE Shadow Area. 
*When GameOS creates SPE of type 1 then it maps only SPE Register Shadow Area into it's address space.

=== metldr  ===

==== Loading metldr  ====

*Physical/Virtual memory address of an isolation module that should be loaded by metldr is written into SPU register '''SPU_In_Mbox'''. The SPU register '''SPU_In_Mbox''' is 32bit, so 64bit memory address is written in 2 steps. 
*MFC relocation is turned off by clearing '''R-bit''' in SPU register '''MFC_SR1'''. By doing this, HV enables real address mode for MFC of SPU. 
*On GameOS, it also works with relocation on. You just have to initialize SLB of SPU and insert valid SLB entries. 
*Physical/Virtual memory address of '''metldr''' is written to SPU registers '''Sig_Notify1''' and '''Sig_Notify2''' 
*Isolation load request is enabled by writing SPU register '''SPU_PrivCntl'''

= VUART  =

VUART is a bi-directional communication link. A VUART object has a peer VUART object. 

Data written to a VUART object is stored NOT in the data buffer of the VUART object but in the data buffer of the peer VUART object. 

== VUART table  ==

Every LPAR has a VUART table. A VUART table has 256 entries. Each entry is a pointer to a VUART object that implements VUART interface. 

0x00677218 (3.15) - address of VUART table of LPAR 1 

Here is the list of all VUART objects in LPAR 1 i found in HV 3.15: 

*0x006ABD90 - VUART 0 
*0x006ABEB0 - VUART 1 
*0x006A3CB0 - VUART 2 
*0x006A3DD0 - VUART 3 
*0x000A3410 - VUART 5 
*0x000A3250 - VUART 6

VUART [0-3] are used by /dev/sc[0-3] respectively. 

VUART [0-3] are linked to VUART objects of different type i could not yet identify. These unknown VUART objects use '''eieio''' opcode a lot. So i think, they communicate with hardware peripheral. 

A write/read to/from /dev/sc[0-3] is a write/read to/from VUART. 

<br>

0x00762AA8 (3.15) - address of VUART table of LPAR 2 

Here is the list of all VUART objects in LPAR 2 i found in HV 3.15: 

*0x00126660 - VUART 0 
*0x000A3010 - VUART 2

VUART 0 and VUART 2 of LPAR 2 are created by Process 9 during LPAR construction. 

== VUART class  ==

=== Member variables  ===

offset 0x48 - pointer to peer VUART object 

offset 0x58 - write pointer into data ring buffer

VUART_write(pointer to VUART object, buf, size, nwritten) - 0x002E8428 (3.15) 

== Guest OS VUART 0 (AV Manager)  ==

All data sent to VUART 0 in LPAR 2 is written into the data buffer of VUART 5 of LPAR 1. 

VUART 5 of LPAR 1 is accessed by Process 9 in LPAR 1 through the file '''/proc/partitions/2/vuart/0'''. 

*Process 9 of LPAR 1 uses RSX syscalls to access RSX driver and memory mapped device access (/dev/ioif0).

== Guest OS VUART 2 (System Manager)  ==

All data sent to VUART 2 in LPAR 2 is written into the data buffer of VUART 6 of LPAR 1. 

VUART 6 of LPAR 1 is accessed by Process 9 in LPAR 1 through the file '''/proc/partitions/2/vuart/2'''. 

*System manager supports 62 (0-61) service ids. 
*Process 9 has a SID table. SID table has 62 entries. 
*Each entry is a pointer to a function responsible for processing SID packets.

= AV Manager  =
Crossreference: [http://wiki.gitbrew.org/wikibrew/PS3:HvReverseEngineering#AV_Manager gitbrew.org::AV Manager] <br />

* AV Manager is running in Process 9 of HV. 
* It communicates with Guest OS through '''/proc/partitions/0/vuart/0 file'''. 
* GameOS accesses AV Manager through '''syscalls 367 - 370'''. 
* PS2 Soft EMU accesses AV Manager also.

* Communicates with '''SYSCON 0 (/dev/sc0)'''
* Communicates with '''IOIF0 (/dev/ioif0 or RSX)'''

==Commands==

===Get HDCP KSV (0xC)===

* Returns HDCP KSV
* HDMI KSV is read from SYSCON
* KSV is stored in memory dump of HV process 9 (where AV Manager runs)

SYSCON request packet:
<pre>
30 01 0200 0000 8033 00000000 0004 0004 11 00 0000 0000ff01
</pre>

===Set HDMI Mode (0x40001)===

* Sets HDMI mode
* Mode is set by SYSCON
* Disabling HDCP

= System Manager (SM)  =

*System Manager (SM) is running in Process 9 of HV. 
*It communicates with Guest OS through '''/proc/partitions/2/vuart/2 file'''. 
*GameOS accesses SM through '''syscalls 372 - 415'''

== System Manager class  ==

=== Member variables  ===

offset 0x10 - LPAR state (8 bytes) 

offset 0x68 - LPAR auth id 

offset 0x70 - LPAR name 

offset 0x90 - LPAR image path 

offset 0x1C0 - LPAR ability (8 bytes)

=== Types of System Manager  ===

*There are 6 different SM types 
*When Process 9 starts it reads profile file, by default '''DEFAULT.SPP''', by sending requests to SPL (Secure Profile Loader) and constructs System Managers listed in this profile file. 
*'''So, the profile file controls which System Manager types are available later.'''

*GameOS file image '''lv2_kernel.self''' is stored on '''/dev/rflash1''' 
*Linux file image is stored on '''/dev/rflash_1x''' or '''/dev/rflash_1xp'''

== Booting Linux LPAR through System Manager  ==

To boot Linux LPAR from GameOS when Linux support was not removed (Ability Mask of PS3 System Manager needs patching&nbsp;!!!): 

*Send SID packet '''SET_NEXT_OP''' with operation '''OP_LPAR_REBOOT''' and the index of Linux system manager to System Manager (VUART 2) 
*Send SID packet '''REQUEST''' with type '''SHUTDOWN''' to System Manager (VUART 2) 
*Execute lv1_panic HV call in GameOS

It should also work when Linux support was removed but Linux system manager was not removed from Process 9 and also assumed that a Linux kernel image is stored at the right place in '''/dev/rflash_1x'''. 

It's just a theory, nothing else, that i gathered during HV reversing. It needs a practical proof. Unfortunately, i don't have access to Hypervisor.

== Booting modified and reencrypted lv2_kernel.self ==

*The System Manager of GameOS sends the path to '''lv2_kernel.self''' to SLL (Secure LPAR Loader) and SLL loads it from FLASH device file '''/dev/rflash1'''
*I stored a new lv2_kernel.self on FLASH directly by writing FLASH from GameOS. It't risky but if you know what you are doing then it's safe. I warned you guys. You could brick your PS3.
*Then i added a new TOC entry to FLASH device which points to the new lv2_kernel.self
*I patched the path to lv2_kernel.self in the System Manager of GameOS so it points to my new GameOS kernel (You need HV rights to do it)
*Then i rebooted GameOS without rebooting HV, so the patched file path should not change
*This method has the advantage that when the new lv2_kernel.self won't work you can just reboot HV and it will load the original lv2_kernel.self again
*lv2_kernel.self can be also loaded from GameOS dev_flash. For that, you have to change the path to '''lv2_kernel.self''' in '''default.spp''' from '''/flh/os/lv2_kernel.self''' to '''/local_sys0/lv2_kernel.self''' and store lv2_kernel.self on dev_flash.

= AV Manager  =

All data sent to VUART 0 in LPAR 2 is written into the data buffer of VUART 5 of LPAR 1. 

VUART 5 of LPAR 1 is accessed by Process 9 in LPAR 1 through the file '''/proc/partitions/2/vuart/0'''. 

*During initialization, AV Manager opens '''/dev/ioif0''' device and maps different address ranges of the device into address space of Process 9 
*'''/dev/ioif0''' is NOT opened and mapped if the value of repository node '''lv1.rsx.enable''' is less than 1 
*'''/dev/ioif0''' is mapped with READ/WRITE protection 
*File descriptor of '''/dev/ioif0''' in Process 9 is 4 
*AV Manager supports a lot more commands than used on Linux 
*Every command is implemented by a class

== Mapped Address Ranges From /dev/ioif0  ==

The base address of '''/dev/ioif0''' is 0x28000000000. The device supports only mmap system call, it cannot be read or written. It also doesn't support ioctl.

= Process socket services  =

== Function ID and Packet ID  ==

*Processes 3, 5 and 6 provide services (functions) to other Processes through sockets (something like RPC). 
*A service is identified by a function ID. 
*Each process has a hash table which maps a function ID to socket port ID. 
*Services (functions) can be further differentiated by a packet ID. 
*To request a service, a Process sends a packet with specified function and packet ID to the Process that provides the service. 
*A process that provides a service (function) has a table of objects which handle different packet IDs. 
*Services are synchronous, a client sends a request and waits for a response. 
*If a Process requests a service that is located in the same Process then the service is called directly and sockets are not used&nbsp;!!! (e.g. SLL requests from DM creating VUART port during GameOS loading, SLL and DM are in the same Process, so SLL calls DM directly)

== SS Packet  ==

*SS means '''Secure Service'''&nbsp;? 
*Processes send SS Packets to request a service or to reply to a service request.

=== Member variables  ===

offset 0x8 - packet ID (8 bytes) 

offset 0x10 - function ID (8 bytes) 

offset 0x18 - return value (4 bytes) 

offset 0x20 - subject ID (2 * 8 bytes) 

=== Header  ===

*All services use a common header. 
*The header of a SS Packet is 0x28 bytes large.
<pre>struct ss_header
{
    uint64_t packet_id;
    uint64_t function_id;
    uint32_t retval;
    uint8_t res[4];
    uint64_t laid;             /* LPAR Authority ID */

== Memory Region class  ==

This class is the base class for different memory region types. 

=== vtable  ===

0x003578B0 (3.15) 

=== Member variables  ===

offset 0x40 - pointer to LPAR object that owns this memory region 

offset 0x48 - type of memory region (8 bytes) 

offset 0x50 - LPAR start address of memory region 

offset 0x58 - size of memory region (8 bytes) 

offset 0x60 - flags (8 bytes) 

offset 0xA0 - log2 of page size

=== Generating New LPAR Memory Region Addresses ===

generate_new_lpar_mem_region_address(?, memory region size, log2(page size), ?, ?) - 002C82E8 (3.15)

generate_new_lpar_mem_region_address - 002C6570 (3.41)

*The function returns a new LPAR memory region address.
*This method is used e.g. in all HV calls which create any kind of memory regions, e.g. '''lv1_allocate_memory''', '''lv1_map_htab''', '''lv1_undocumented_function_114''', '''lv1_construct_logical_spe''', '''lv1_map_device_mmio_region''' or '''syscall 0x10040'''.

==== Encoding LPAR Memory Region Start Addresses and Sizes ====

*Size of LPAR memory region is encoded in the LPAR memory region start address.
*That is why e.g. the LPAR Memory Region Start Addresses of LPAR Memory Region of size 4096 byte begin with '''0x300000000000''', '''0x300000000000 >> 42 = 0xC = log2(4096)'''.
*Each LPAR has a counter (8 bytes) which is incremented by 1 every time a new LPAR Memory Region is created.
*Before incrementing, the counter is shifted left by '''log2(LPAR Memory Region Size)''' and ored with '''log2(LPAR Memory Region Size) << 42'''.

 LPAR Memory Region Start Address >> 42 = log2(LPAR Memory Region Size)

 LPAR Memory Region Start Address = (log2(LPAR Memory Region Size) << 42) |
    (counter << log2(LPAR Memory Region Size))

===== LPAR Memory Region Address Counter =====

*LPAR Memory Region Address Counter is stored at address: '''0x38(LPAR ptr) + 0x9E8'''
*LPAR1's Memory Region Address Counter is at address '''0x00677A48''' in HV dump 3.15
*LPAR2's Memory Region Address Counter is at address '''0x007632D8''' in HV dump 3.15
*LPAR1's Memory Region Address Counter is at address '''0x00677A48''' in HV dump 3.41
*LPAR2's Memory Region Address Counter is at address '''0x00161E68''' in HV dump 3.41

== Physical Memory Region class  ==

This type of memory region is created e.g. in '''lv1_allocate_memory''' HV call or in '''syscall 0x10000'''. 

=== vtable  ===

0x00357D08 (3.15) 

=== Member variables  ===

offset 0xB0 - pointer to object that stores a list of addresses of physical pages owned by this memory region 

offset 0xB8 - pointer to LPAR object that owns this memory region 

offset 0xC0 - reference counter (8 bytes)

So, Linux kernel should be located at physical address 0x8000000 and Linux syscall handler at 0x8000C00. Too bad that the HV dump is not large enough. 

=== GameOS Physical Memory Regions  ===

*GameOS allocates nearly all physical memory of PS3 for itself&nbsp;!!! That is why new HV calls '''lv1_allocate_memory''' with large memory region sizes will fail. 
*So when someone wants a large piece of physical memory, he can borrow it from GameOS's LPAR memory region that starts at '''0x700020000000'''. It can be used for example to send update packages to Update Manager which are very large.

Here is the list of physical memory regions of GameOS i found in HV 3.41:

=== GameOS HTAB  ===

*HTAB of GameOS is already mapped into address space of GameOS so that is why HV call '''lv1_map_htab''' will fail until you unmap it with '''lv1_unmap_htab''' 
*Effective address of GameOS HTAB is '''0x800000000F000000''' 
*Virtual address of GameOS HTAB is '''0xF000000''' 
*Size of GameOS HTAB is '''0x40000''' 
*GameOS HTAB supports large pages of size '''64K''' and '''1M'''

== Direct Map Memory Region class ==

This type of memory region is created in HV call '''lv1_undocumented_function_114'''.
'''lv1_undocumented_function_114''' allows you to map any memory address into LPAR's memory address.

* The HV call '''lv1_undocumented_function_115''' destroys a memory region of this type.
* HV allows GameOS to create objects of this type of size 0 only !!! But it can be exploited with a dangling HTAB entry.

=== Exploiting HV with memory glitching and HV call lv1_undocumented_function_114 ===

Here is a short description of the method i used to exploit HV from GameOS 3.15 and 3.41.

* First i used the Geohot's method to create a dangling HTAB entry.
* Making memory glitch work on GameOS was the largest of my obstacles but i solved it and i'm able to create a dangling HTAB entry from GameOS within 1-3 minutes.
* Then i created many '''Direct Map Memory Region''' objects of size 0 with HV call '''lv1_undocumented_function_114''' and checked if they are within the page to which the dangling HTAB entry points to.
* When i found one such '''Direct Map Memory Region''' object i patched the size of this object to 0x1000. Then i pointed this memory region object to the code of HV call '''lv1_undocumented_function_114''' and patched 4 bytes in this HV call which allows me to create any '''Direct Map Memory Region''' objects without any restrictions.
* Function '''LPAR_construct_direct_mapping_mem_region''' which is used by HV call '''lv1_undocumented_function_114''' has a parameter (register %r9) and when this parameter is not 0 then HV will allow you to create any '''Direct Map Memory Region''' objects without restrictions, but unfortunately the HV call '''lv1_undocumented_function_114''' passes 0 in this parameter, so i just patched it.
* Then i mapped whole HV memory range with the patched HV call '''lv1_undocumented_function_114''' into the address space of GameOS.
* And now you have read/write access to the whole HV.
* $ONY could fix this exploit by disallowing creating of '''Direct Map Memory Region''' objects of size 0, but i know tons of other HV C++ classes which will allow me to exploit the HV in a similar way, so it wouldn't bring $ONY anything :-) And they have to change member variable offsets in those objects to make sure that i cannot patch them easily :-)

= Event Notification  =

*Event Notfication is used e.g. to notify a LPAR about some event, e.g. device interrupt or notify a LPAR about destruction of another LPAR. 
*For example Process 9 is notified through Event Notification when LPAR 2 is destructed. 
*During LPAR construction, Process 9 creates an Outlet object with '''syscall 0x1001A''' and then passes the outlet ID to the '''syscall 0x10009''' that constructs the LINUX LPAR. In this way Process 9 is notified when LINUX LPAR is destructed.

== Outlet class  ==

This is the base Outlet class. There are different types of Outlet and they derive from this base class. 

=== vtable  ===

0x00357DC0 (3.15) 

=== Member variables  ===

offset 0x30 - type (8 bytes) 

offset 0x38 - pointer to LPAR that owns this Outlet object 

offset 0x48 - outlet id (8 bytes) 

offset 0x90 - VIRQ assigned to this Outlet object (4 bytes) 

== Event Receive Port class  ==

*This type of Outlet is created e.g. in '''lv1_construct_event_receive_port''' and in '''syscall 0x1001A'''. 
*HV calls '''lv1_connect_irq_plug''' and '''lv1_connect_irq_plug_ext''' assigns a VIRQ to Event Receive Port object.

=== vtable  ===

0x00357E88 

== VUART Outlet  ==

*HV supports only one VUART Outlet per LPAR 
*'''lv1_configure_virtual_uart_irq''' constructs a VUART Outlet object and passes the address of LPAR's VUART IRQ Bitmap to HV

=== vtable  ===

0x00357DC0 

=== VUART IRQ Bitmap  ===

*At address 0x38(LPAR ptr) + 0x158 is the VUART IRQ Bitmap owned by HV for LPAR (4 * 8 bytes = 256 bits) 
*At address 0x38(LPAR ptr) + 0x150 is stored the physical address of LPAR's VUART IRQ Bitmap that was passed to '''lv1_configure_virtual_uart_irq''' 
*When a VUART interrupt is generated by HV then first the VUART IRQ Bitmap owned by HV is updated and then this bitmap is copied to LPAR's VUART IRQ Bitmap, so VUART IRQ Bitmap is stored twice, once in HV and once in LPAR, just like IRQ State Bitmap. 
*VUART IRQ Bitmap is not allowed to cross page boundary of LPAR memory region where it is stored. HV checks it and makes sure that it doesn't happen. 
*'''GameOS 3.41''' VUART IRQ bitmap is at address '''0x80000000003556E8''' and of size '''32 bytes (256 bits, each bit corresponds to a VUART port)'''. 
*'''GameOS 3.15''' VUART IRQ bitmap is at address '''0x8000000000354768'''.

= Logical PPE  =

*Logical PPE is used for interrupt management of LPAR. 
*A Logical PPE object is created in '''syscall 0x10005'''. It' used e.g. in Process 9 during LPAR construction. 
*'''syscall 0x10007''' activates a Logical PPE object 
*0x67F0(HSPRG0) - pointer to currently active Logical PPE object (in HV dump it points to Linux PPE object naturally because the dump was made on Linux, so Linux LPAR was active at that time) 
*E.g. '''lv1_get_logical_ppe_id''', '''lv1_start_ppe_periodic_tracer''' and '''lv1_set_ppe_periodic_tracer_frequency''' grab the currently active Logical PPE object

== vtable  ==

0x00357DF0 (3.15)

== IRQ State Bitmap  ==

*There is one IRQ State Bitmap (256 bits = 32 bytes) per thread of Logical PPE 
*'''HSPRG0 value is per thread''', so there are 2 HSPRG0 values in HV dump&nbsp;!!! 
*The IRQ State Bitmap of a thread is stored at -0x68E0(HSPRG0) 
*When an Event or Interrupt happens then the bitmap at 0x68E0(HSPRG0) is updated 
*The physical address of '''LPAR's IRQ State Bitmap''' of thread is stored at offset -0x68C0(HSPRG0) 
*The address of LPAR's IRQ State Bitmap is passed to Hypervisor through HV call '''lv1_configure_irq_state_bitmap''' 
*'''lv1_detect_pending_interrupts''' returns value of current IRQ State Bitmap. 
*The IRQ State Bitmap is updated if an Outlet object is assigned to VIRQ and when Outlet generates an event 
*After IRQ State Bitmap update, it's copied to LPAR's IRQ State Bitmap and a hardware interrupt is generated so that LPAR can read it's IRQ State Bitmap and handle interrupts. 
*So, IRQ State Bitmap is stored twice, once in HV and once in LPAR, just like VUART IRQ Bitmap. 
*'''GameOS''' IRQ state bitmap is stored at address '''SPRG0 + 0x1C0 and of size 64 bytes (256 bits state + 256 bits mask) per thread of Cell CPU'''. So there are 2 IRQ state bitmaps.

==Sending Packets==

* Before sending new packet to SYSCON, the Hypervisor checks 2 words at offsets 0x2400008DFF0 and 0x2400008CFF4.
* The Hypervisor busy waits until (value + 1) at offset 0x2400008CFF4 is NOT equal to value at offset 0x2400008DFF0.
* The packet is sent with 4 byte transfers.
* First, the Hypervisor sends the header of the packet, 4 word transfers.
* The header is written beginning at the address 0x2400008D000.
* After that the Hypervisor sends the body of the packet, with 4 byte transfers too.
* The body is written beginning at the address 0x2400008D010.
* If the packet size is NOT divisible by 4 then the Hypervisor sends the remaining bytes (at most 3) as a word padded with 0s.
* After the packet body was written, the Hypervisor calculates checksum of the whole packet and writes it at the address where the last word of packet body was written + 4.
<pre>
uint32_t cksum = 0;

for (i = 0; i < packet_size; i++)
    cksum -= packet[i];

cksum = cksum & 0xffff;
</pre>
* After the packet checksum was written, the Hypervisor reads the value at offset 0x2400008DFF0, modifies it and stores back:
<pre> 
value = value + 1;
value &= 0xffff;
value = (value << 16) | value;
</pre>
* To notify the SYSCON about the new packet, the Hypervisor writes 0x1 to address 0x2400008E100.

==Receiving Packets==

* The Hypervisor installs an interrupt handler for the SYSCON.
* First, the Hypervisor reads a word from address 0x2400008E000, ors it with 0xFFFFFFFD and writes the value back.
* Then, the Hypervisor reads a word from address 0x2400008E004 and tests if bit 0x2 is set or not. The bit 0x2 should be not 0 or else the Hypervisor panics.
* After that, the Hypervisor reads a word at address 0x2400008CFF0 and 0x2400008DFF4. If there is a new packet pending from SYSCON, then the (value + 1) at 0x2400008CFF0 should be equal the value at 0x2400008DFF4.
* The Hypervisor reads the header of the packet beginning at the address 0x2400008C000.
* The header is read with 4 word transfers by the Hypervisor.
* The byte at offset 1 in the packet header must be 1 or else the Hypervisor discards the packet as invalid.
* The Hypervisor calculates the checksum of the packet header and checks it with the checksum stored in the header. If they don't match then the Hypervisor discards the packet.
* The Hypervisor reads the body of the packet beginning at the address 0x2400008C010.
* The header and the body of the received packet can be read as many times as you want !!! They remain until next SYSCON packet is received
which gives us the possibility to communicate with SYSCON on Linux easily :)

==sys.hw.config==

* Value of the loader parameter "sys.hw.config" controls if Gelic WLAN is enabled or not.
* Value of the loader parameter "sys.hw.config" is stored in the repository node "sys.hw.config" too.
* If bit '''0x40000''' is set then LV1 allows using Gelic WLAN interface from LV2.
* Value on my PS3 slim '''0x4e00ffff0a03bc3c''' with Gelic WLAN interface disabled. As you can see, the Gelic WLAN interface is disabled and LV1 doesn't allow using of LV1 calls 196 and 195. It returns LV1_CONDITION_NOT_SATISFIED.
* GameOS checks bit '''0x40000''' of the repository node "sys.hw.config" during network initialization and if it's set then LV2 initializes Gelic WLAN interface.
* Check your "sys.hw.config" repository node and if bit '''0x40000''' is set then you are a lucky owner of a PS3 model with the old WLAN interface.
* '''On newer PS3 models, GameOS uses USB interface to communicate with WLAN.'''
* On PS3 models, where bit '''0x40000''' is NOT set in "sys.hw.config" repository node, the new USB interface is used.

''Note:[http://www.ps3devwiki.com/index.php?title=Wifi old vs. new]: Old == CECHA up to CECHK, New == CECHL and later''

== Control Interface ==

HV calls 195 and 196 are used by GameOS to send commands to Gelic device directly.

=== lv1_undocumented_function_196 ===

==== Parameters ====

r3 - LPAR address of data buffer

r4 - size of data buffer

r5 - must be 0

=== lv1_undocumented_function_195 ===

==== Parameters ====

r3 - command (16 bit value)

r4 - command data size

r5 - must be 0

=== Data Buffer ===

* Data Buffer passed to HV call 196 is divided into 2 parts.
* The first 0x800 bytes are for sending and receiving command data
* The remaining 0x800 bytes are for event notification.

=== Command Data Buffer ===

* Every command data sent to Gelic device contains header of size '''0xC'''
* After the header follows the command data
* After the Gelic device processed the command, it notifies LV2 kernel about command completion by sending an interrupt

==== Header ====

* Size is '''0xc'''.
* Byte order is little-endian.
* Header data in a request command buffer is always all 0s.

0x0 - command = request command + 1 (2 bytes)

0x4 - result, 0x1 - success ??? 0x2 - buffer too small ??? (2 bytes)

0x6 - body size (2 bytes)

=== Event Data Buffer ===

* The Gelic device notifies LV2 kernel by sending an interrupt when new events are available
* Event Data Buffer has 8 bytes header
* The remaining bytes are divided into event slots
* Each event slot is of size 64 bytes
* Events are in little-endian format

==== Header ====

offset 0x0 - GET index (4 bytes)

offset 0x4 - PUT index (4 bytes)

* GET index is updated by Gelic driver. The Gelic driver reads events beginning with the event slot at index GET.
* PUT index is the index of event entry where next Gelic event will be stored by the Gelic device.
* If GET index is equal to PUT index then there are no Gelic events.

=== GameOS ===

* LV2 syscall 726 sends Gelic device command and blocks until a response from the Gelic device arrives
* LV2 kernel uses this LV1 interface to send commands to Gelic device internally too, probably for wireless controllers and Wake On WLAN. 
* The system call 726 is used heavily by VSH.

== Enabling WLAN Gelic On FAT ==

Linux kernel doesn't use Gelic Device Control Interface like GameOS does it.
To get WLAN working on Linux booted with GameOS rights, we have to disable 
Gelic Device Control Interface first because it's enabled for GameOS by default.

The value of repository node "ios.net.eurus.lpar" controls access to Gelic Device Control Interface.
It's a bitmap. The position of a bit corresponds to LPAR id. During GameOS booting, HV process 9 (System Manager) sets bit at postion 2 to 1 which means enable Gelic Device Control Interface for LPAR 2.

To disable Gelic Device Control Interface on Linux, first unload Gelic device driver, then set
value of repository node "ios.net.eurus.lpar" to 0 and load Gelic device driver again. After that WLAN should work again but only on FATs.

For PS3 Slim we need a new Linux Gelic device driver which uses Gelic Device Control Interface directly.


==USB WLAN Interface (Codename Jupiter 2)==

* On new PS3 models, WLAN interface is USB.
* '''Good news is that  the same commands are used as with LV1 calls 196 and 195'''.
* There are 2 wireless devices: Station and AP.
* I got WLAN scan working.

===Endpoints===

* LV2 uses 3 USB endpoints of interface 3,4 and 5 to communicate with WLAN.
* Endpoints EP5 IN/OUT, EP6 IN/OUT and EP7 IN/OUT.
* '''WLAN commands''' are sent to endpoint '''EP5 OUT''' with '''interrupt transfers'''.
* '''WLAN events''' and '''WLAN command responses''' are received on endpoint '''EP5 IN''' with '''interrupt transfers'''.
* LV2 opens a USB communication pipe to endpoint EP5 IN and EP5 OUT.
* In my LV2 3.55 dump, pipe to EP5 IN has id '''0x2''' and pipe to EP5 OUT has id '''0x3'''. Array of all opened USB pipes is at address '''0x80000000004bd000''' in my LV2 3.55 dump.
* EP5 is used to send commands to Jupiter and receive events from it.
* EP6 is used to send/receive data packets to/from the 1st WLAN device.
* EP7 is used to send/receive data packets to/from the 2nd WLAN device.
* '''lsusb is buggy on big-endian arch and shows some fields with bytes swapped !!!'''

===Device Initialization===

* LV2 does 2 control transfers to EP0 during WLAN initialization
* First control transfer sends magic '''0x20''' data to device as '''CLEAR_FEATURE''' request.
* Second control transfer reads '''0x2''' bytes device status. On my PS3 slim, the status data is always '''0x2031''' if you send the right magic.
* Magic data sent in first control transfer is stored in LV2.
* '''If you send wrong magic, the first control transfer will fail !!!'''
* LV2 uses a state machine to initialize the Jupiter device. The state machine has 17 states.

==== Magic Data in Control Transfer ====

===Associate with AP===

* I got association with AP working.
* If  WLAN device is connected to an AP then the green LED is on, when data is received then the LED blinks.
* '''Data reception works finally !!!'''

====How to Associate with WPA AP====
* Set common configuration (command 0x1005)
* Set WPA configuration (command 0x1019)
* Set rate configuration (command 0x1ed)
* Associate (command 0x1001)

===Packet Reception===

* EP6 IN and EP7 IN endpoints are used for packet reception
* LV2 sends bulk transfers to both endpoints
* '''4''' bulk transfers are sent simultaneously for each enpoint
* Every bulk transfer is of size '''0x620'''
* '''Make sure you set multicast address filter properly or else you won't receive broadcast packets !!!'''
* Bulk transfers returned by the host controller which do not contain any data have size of '''0x10''' bytes else transfers contain valid Ethernet frame. All 802.11 related data is stripped by the WLAN Gelic device.
* '''Make sure you set right MAC address with command 0x115b else device won't be able to receive packets destined to its own MAC address !!!'''

====Multicast Address Filter====

* WLAN Gelic device supports hardware multicast address filtering
* Multicast address filtering is implemented with MAC address hashing and filter bitmap
* Filter bitmap is of size '''4 * 8''' bytes
* Multicast address filter is set with command '''0x1161'''

=====MAC Address Hash Function=====

* Used by LV2

<pre>
unsigned char hash(unsigned char *data, unsigned int size)
{
        unsigned int hash;
        int i, j;

        /*XXX: reverse data bits */

        hash = 0xffffffff;

        for (i = 0; i < size; i++) {
                hash = (((unsigned int) data[i]) << 24) ^ hash;

                for (j = 0; j < 8; j++) {
                        if (((int) hash) >= 0) {
                                hash = hash << 1;
                        } else {
                                hash = (hash << 1) ^ 0x04c10000;
                                hash = hash ^ 0x00001db7;
                        }
                }
        }

        hash = ((hash >> 24) & 0xf8) | (hash & 0x7);

        return hash & 0xff;
}

h = hash(mac_addr, 6);
v = 1 << (h & 0x1f);    /* word value in filter */
p = h >> 5;             /* word position in filter */


For broadcast address:
------------------------

v = 0x20000000
p = 7

That's why 0x20 is used with command 0x1161 !!! Without it the device won't deliver broadcast traffic.
Learned it the hard way, after 2 days of trying to get packet reception working :)
</pre>

===Packet Transmission===

* Tx packets are sent to EP6 OUT
* Tx packets are normal Ethernet frames, they don't contain any WLAN data or other headers

===AP Mode===

* I got AP mode working with security disabled for now

====AP Mode with Security Disabled====

* Set AP SSID (command 0x5)
* Set channel (command 0x11)
* Set AP opmode (command 0xb9)
* Configure rate control (command 0x1ed)
* Set AP WEP Configuration (command 0x5b, all 0s)
* Command 0x61 (param 0x0)
* Command 0xc5 (param 0x0)
* Command 0x1 (param 0x1)
* Command 0x1dd (param 0x2)
* Now green LED should be on

===ps3-jupiter Linux Drivers===

* ps3_jupiter.ko is the common part of STA and AP mode. It implements a command interface to WLAN Gelic device and disptaches events to STA and AP drivers.
* ps3_jupiter_sta.ko is a STA mode implementation.
* ps3_jupiter_ap.ko is a AP mode implementation.
* Simple scanning works already in STA mode (try it out with '''iwlist scan''')
* Packet reception works
* Packet transmission works
* '''WPA/WPA2''' fully working and usable with '''wpa_supplicant'''


'''Finally, after several weeks of hard programming and reversing, the WLAN driver ps3_jupiter_sta achieved the milestone where i can use it with WPA2 :) I actually use it currently with WPA2 on my PS3 slim. It works damn !!! Try it out and report bugs and problems to me.'''

====TODO====

* Implement association in STA mode (finished)
* Implement packet reception and transmission in STA mode (finished)
* Implement WEP support
* Implement AP mode
* Find out if Jupiter supports Monitor mode and if yes how to enable it
* Implement EURUS driver for PHATs (has many advantages over the old OtherOS approach, e.g. AP mode)
* Port to FreeBSD

==LV2 Network Stack==

* LV2 uses BSD network stack, e.g. '''struct mbuf'''
* It's almost identical to FreeBSD network stack.

===Network Device===

====IOCTLs====

==HV Calls==

===lv1_gpu_memory_allocate===

* LV1 supports 16 memory handles simultaneously.
* LV1 uses a bitmap to manage GPU VRAM.
* The bitmap is located in LV1 memory, 4 double words.
* Each bit corresponds to 1MB VRAM, 256bit = 256MB VRAM.
* 2MB at the top of VRAM are preallocated as you can see below.

<pre>
<memory handle> = 0x5a5a5a5a xor <memory handle index>
</pre>

====Memory Context Object====

offset 0x8 - memory handle (4 bytes)

offset 0x10 - VRAM LPAR start address (8 bytes)

offset 0x18 - VRAM LPAR end address (8 bytes)

====Test====

* The offset of bitmap could be different on your system because it's allocated dynamically.
* '''First 9MB of VRAM were allocated by ps3fb Linux driver.'''

Before allocating VRAM:
<pre>
glevand@debian-hdd:~$ sudo dd if=/dev/ps3ram bs=1 count=$((0x20)) skip=$((0x1f85b0)) | hexdump -C 
00000000  00 00 00 00 00 00 01 ff  00 00 00 00 00 00 00 00  |.......ÿ........|

</pre>

After allocating 32 MB VRAM:
<pre>
glevand@debian-hdd:~$ sudo dd if=/dev/ps3ram bs=1 count=$((0x20)) skip=$((0x1f85b0)) | hexdump -C 
00000000  00 00 01 ff ff ff ff ff  00 00 00 00 00 00 00 00  |...ÿÿÿÿÿ........|
00000010  00 00 00 00 00 00 00 00  c0 00 00 00 00 00 00 00  |........À.......|
</pre>

===lv1_gpu_context_allocate===

* Register %r4 is flags.
* '''Found the place in LV1 where LV1 sets IO page size for GART memory mapping. We could patch it and set to 4KB. That would make a lot of things easier for RSX developers on Linux.'''
* 1MB pages make RSX driver for Linux hard to implement because allocating 1Mb contiguous memory chunk on Linux is very very hard especially on a system with only 256MB and which was running for some time.

* LV1 supports 16 contexts simultaneously.
* LV1 has an array of context pointers.
* Each context has an index and a handle. The handle is derived from the index of the context.

<pre>
<context handle> = 0x55555555 xor <context index>
</pre>

* Thats why first created context will have handle 0x55555555.

====Context Object====

offset 0x8 - handle (4 bytes)

offset 0x48 - IO page size, valid range is 4kB, 64KB and 1MB (8 bytes)

====Flags====

'''0x2 - tells LV1 to use 64KB pages for GART memory mapping else LV1 uses 1MB pages'''

===lv1_gpu_context_iomap===

* Internally uses lv1_put_iopte function
* IO page size is the one set during lv1_gpu_context_allocate
* IO address space id is 0x0. IO id is 0x1.

===lv1_gpu_context_attribute===

====Attribute 0x1====

=====FIFO Command Buffer Setup=====

<pre>
lv1_gpu_context_attribute(context handle, 0x1, PUT offset, GET offset, 0x0, 0x0)
</pre>

====Attribute 0x101====

=====Set Flip Mode=====

<pre>
lv1_gpu_attribute(0x2, 0x1 /* head */, 0x0, 0x0)
lv1_gpu_context_attribute(context handle, 0x101, 0x1 /* head */, sync mode, 0x0, 0x0)
</pre>

====Attribute 0x104====

=====Set Display Buffer=====

<pre>
lv1_gpu_context_attribute(context handle, 0x104, id, width << 32 | height, pitch << 32 | offset, 0x0)
</pre>

====Attribute 0x10a====

=====Get Flip Status=====

* Reads a value at offset '''0x10C0 + 0x1 * 0x40''' in lpar_reports memory.

=====Reset Flip Status=====

<pre>
lv1_gpu_context_attribute(context handle, 0x10a, 0x1 /* id */, 0x7fffffff /* mask */, 0x0 /* value */, 0x0)
</pre>

* The LV1 call '''lv1_gpu_context_attribute(0x10a)''' accesses LPAR memory returned in '''lpar_reports''' by LV1 call '''lv1_gpu_context_allocate'''.
* Offset into lpar_reports is '''0x10C0 + id * 0x40 = 0x10C0 + 0x1 * 0x40'''.
* Why not access lpar_reports memory directly and use LV1 call instead ???

====Attribute 0x10b====

* '''This attribute is NOT available on 3.15 LV1 e.g. but on 3.41 it's implemented.'''

=====Set Cursor Position=====

<pre>
lv1_gpu_context_attribute(context handle, 0x10b, 0x1, 0x3, x, y)
</pre>

=====Set Cursor Image Offset=====

<pre>
lv1_gpu_context_attribute(context handle, 0x10b, 0x1, 0x2, offset, 0x0)
</pre>

====Attribute 0x10c====

* '''This attribute is NOT available on 3.15 LV1 e.g. but on 3.41 it's implemented.'''

=====Cursor Function 1=====

=====Set Invalidate Tile=====

=====Bind Tile=====

=====Unbind Tile=====

====Attribute 0x301====

=====Set Zcull=====

=====Bind Zcull=====

=====Unbind Zcull=====

====Attribute 0x601====

* Copies data from GART memory to VRAM.
* LV1 uses internally the FIFO command buffer passed by ps3fb driver with lv1_gpu_context_iomap.

==FIFO Command Buffer==

===FIFO Control Registers===

* LV1 call '''lv1_gpu_context_allocate''' returns LPAR address of FIFO control registers.
* You have to map it into Linux address space before you can access FIFO control registers.
* Value of PUT and GET registers are NOT expressed in Linux address space but in RSX address space. You have to convert it to RSX address space.
* GET register is read-only and is modified by RSX while it's processing FIFO commands.

===Kicking FIFO Command Buffer===

* As long as values of GET and PUT FIFO control registers are equal, RSX doesn't process commands from the FIFO command buffer.
* When the value of PUT register is not equal to the value of GET register, RSX starts processing commands in the FIFO command buffer.
* To execute FIFO commands, place them in the FIFO command buffer and change the value of PUT register.

===FIFO Setup Programs of emer_init.self===

* [[PS3:HvReverseEngineering:emer_init.self:Program 1]]
* [[PS3:HvReverseEngineering:emer_init.self:Program 2]]
* [[PS3:HvReverseEngineering:emer_init.self:Program 3]]

===FIFO Commands===

[[PS3:HvReverseEngineering:RSXFIFOCommands]]

===Example How to Use FIFO Command Buffer===

Here is a small Linux kernel module which shows you how to use FIFO command buffer on Linux.

* RSX allows to create multiple contexts.
* This kernel module should run without problems with '''ps3fb''' driver already running.
* Make sure you unload '''ps3vram''' driver before running this module because '''ps3vram''' allocates all available RSX memory for itself and because of this, '''lv1_gpu_memory_allocate''' will always fail.
* This kernel module lets the RSX execute a simple program which contains only NOP (No Operation) commands.

As you see, RSX processed our FIFO commands :)

==Linux Driver==

* '''DRI/DRM is the ONLY way to go !!! No hacks like kernel modules with tons of IOCTLs !!!'''
* First implement 2D acceleration and then add 3D support
* The driver consists of 2 parts: '''DDX driver''' for X11 (user space) and '''DRM driver''' for Linux Kernel (kernel space)
* First implement DRM driver and test it from user space without DDX and libdrm by talking to it directly

===DDX Driver===

* Use '''libdrm'''
* Use '''EXA API''' for 2D acceleration on X11 (or maybe use '''XAA API''')
* Use '''Kernel Mode Setting'''

===DRM Driver===

* Extend '''nouveau''' driver or create a new one ???
* '''Decision: create new DRM driver in order to learn how DRM framework in Linux kernel works and because we have to use LV1 calls to access RSX (and because it's a lot more fun to do it on my own). But use nouveau as an example for DRM driver. Maybe i should better use radeon DRM driver as an example beacuse it seems to be better designed and implemnted !!!'''
* The driver is very low level and allows direct access to almost all RSX funtions, e.g. FIFO buffer, to achieve maximum performance.
* All data buffers, e.g. vertices and textures, are managed by DRM framework (Linux kernel). To avoid copying from user to kernel space, the buffers will be mmaped into user space.
* Provides an interface to manage graphic objects in VRAM.
* Use '''TTM''' or '''GEM''' ??? TTM is used by radeon and nouvea drivers, so i guess we could use it too. GEM is for Intel chips.
* Extend '''libdrm''' library to support new DRM driver.
* Fences can be implemented with '''RSX REF Control Register'''

====Memory Management====

* Size of all memory objects must be multiple of the page size (4096 bytes) even if a smaller size is requested by user
* Nouveau driver uses IOCTL '''DRM_NOUVEAU_GEM_NEW''' to allocate memory objects in VRAM or GART. The IOCTL returns the handle of the newly allocated memory object.
* An example from Mesa how memory objects are used: [http://fxr.watson.org/fxr/source/external/bsd/drm/dist/libdrm/nouveau/nouveau_bo.c?v=NETBSD;im=10] [http://www.opensource.apple.com/source/X11libs/X11libs-60/mesa/Mesa-7.8.2/src/mesa/drivers/dri/nouveau/nouveau_bufferobj.c]

====Video RAM====

* VRAM is allocated once during context creating and cannot be changed during the whole life of the context.
* '''lv1_gpu_memory_allocate''' returns LPAR address of allocated VRAM which can be mapped into kernel address space.
* '''VRAM starts at offset 0x0 in GPU address space.'''
* VRAM heap management is necessary, use e.g. TTM (ttm_bo_init_mm).
* This memory type is used e.g. for vertices or textures.
* It should be mappable from user space in order to allow user to put data there.
* GameOS calls it '''Local Memory'''.
* VRAM can be mapped into kernel-space with '''ioremap'''.
* To map VRAM into user-space map it first into kernel-space with '''ioremap''' and then use '''remap_pfn_range''' to map into user-space.
* Use '''VM_IO''' flag for this kind of memory when mapping it into user-space.
* Mapping examples: [http://www.scs.ch/~frey/linux/memorymap.html] [http://www.cs.fsu.edu/~baker/devices/projects/antgeo/avnet_june19/pci_avnet.c]

====GART Memory====

* GART memory region is a memory region in System Memory but accessible by RSX through GART [http://dri.freedesktop.org/wiki/GART].
* GameOS calls it '''Main Memory'''.
* '''Problem: lv1_gpu_context_iomap supports ONLY 1MB and 64kB pages'''
* Size of system memory objects mapped into GPU address space should be either multiple of 1MB which means wasting lots of RAM and we don't have enough of it anyways. This solution is NOT suitable.
* Or place several GART memory objects into 1 MB page and map it. That would mean we have to use memory manager for each 1MB page.
* That means, we have to allocate 1MB page even if user requested a smaller memory region. Then initialize a heap manager for this 1MB page and return ONLY requested size. The following requests for GART memory regions can be satisfied from the previously allocated 1MB pages which still have enough free memory.
* FIFO command buffer is an example of a GART memory object which has to be mapped into GPU address space with lv1_gpu_context_iomap before it can be used by RSX.
* User allocates FIFO command buffer in GART address space, maps it into user space, write commands into it and then pushes it to DRM driver which maps it into RSX address space and CALLs it.
* '''TTM: TTM_PL_FLAG_TT for GART memory'''
* '''GameOS applications using GCM library map GART memory beginning at offset 0x10000000 or 0x20000000, just after where the whole VRAM is mapped.'''
* '''Don't use kmalloc for this type of memory. Use __get_free_pages and mark pages with flag VM_RESERVED before exporting it to user-space else they can be swapped out.'''
* TTM uses '''struct ttm_backend_func''' to call driver specific GART mapping functions. '''nouveau_sgdma.c''' handles GART memory mapping.

====CPU Memory====

* This type of memory cannot be accessed by RSX at all.
* Because this type of memory is not mapped into RSX address space through GART we don't need to allocate it in 1MB multiples.
* What do we need it for ???

====Mapping Memory Objects into Kernel-Space====

* Nouveau driver uses '''ttm_bo_kmap''' to map memory objects into kernel-space (see '''ttm_bo_util.c''').
* Nouveau driver uses '''ttm_bo_ioremap''' to map IO memory into kernel-space, e.g. VRAM or GPU registers (see '''ttm_bo_util.c''') which uses '''ioremp_wc''' or '''ioremp_nocache'''.
* TTM uses page-wise allocation for buffers. The buffers are contiguous ONLY in a single page. That has a huge advantage over allocating 1MB contiguous memory blocks in kernel space. It's far easier to allocate a single page in Linux kernel than 1MB memory chunk, especially on PS3 arch which has only 256MB.
* '''Problem: lv1_gpu_context_iomap allows ONLY 1MB pages. Use lv1_put_iopte ???'''. See [http://lwn.net/Articles/304188/], [http://lxr.free-electrons.com/source/arch/powerpc/platforms/ps3/mm.c?a=sh#L562],  [http://wiki.ps2dev.org/ps3:hypervisor:lv1_put_iopte ] and [http://wiki.ps2dev.org/ps3:hypervisor:lv1_gpu_context_iomap].
* Yes, we can use '''lv1_put_iopte''' instead of '''lv1_gpu_context_iomap'''. That would solve the problem with 1MB pages on Linux. Both LV1 calls use the same internal LV1 function to map memory pages.
* '''lv1_gpu_context_iomap uses IOAS_ID 0 and IOID 1.'''
* TTM allows to map a buffer multiple times. Mapping information is stored in '''struct ttm_bo_kmap_obj'''.
* '''To make single allocated pages look contiguous to kernel-space, TTM uses vmap'''.
* '''It is possible to use 64KB pages for GART mapping without patching LV1. To enable 4KB pages support we have to patch LV1.'''
* Tested with 64kB IO page size. It works fine.

====Mapping Memory Objects into User-Space====

* User-space programs should be able to allocate memory objects in VRAM or GART and map it with '''mmap syscall'''.
* See '''nouveau_ttm.c:nouveau_ttm_mmap'''.
* Mapping memory objects into user-space avoids copying of data between user/kernel spaces.
* Problem: how to identify memory objects ???
* '''libdrm''' uses handles which are returned by DRM kernel driver when a new memory object is created. The handle is passed to mmap syscall as parameter '''offset'''. DRM driver looks up the handle and identifies the appropriate memory object which is mapped into user-space then.
* Nouveau driver uses TTM framework to map memory objects into user-space. TTM doesn't map all pages owned by the memory object at once but installs '''VM operation fault''' which maps single pages on demand. It makes sense because user application rarely accesses all pages of the mapped memory object at once.
* To map memory objects located in VRAM we have to map it into kernel space first with '''ioremap'''.

====FIFO Command Buffer====

* Every context has its own one main FIFO command buffer which is NOT accessible directly by user space.
* User-space applications can allocate additional FIFO command buffers in GART memory space, map it into user space, store commands there and submit to DRM driver.
* Nouveau driver uses IOCTL '''NOUVEAU_GEM_PUSHBUF''' to execute FIFO command buffers. See '''nouveau_gem.c:nouveau_gem_ioctl_pushbuf'''.
* By user applications submitted FIFO command buffers are mapped by DRM driver into RSX address space first and then executed with CALL command.
* '''Problem: All references to graphics objects contained in FIFO command buffers must be expressed in RSX address space. How does user space know the right offsets of the referenced objects ???'''
* To solve the above problem, Nouveau driver uses relocations which are submitted to DRM driver together with FIFO command buffers. The DRM driver applies the specified relocations before executing the FIFO command buffer. See '''nouveau_gem.c:nouveau_gem_pushbuf_reloc_apply'''.
* Relocations contain memory object handles which they apply to. The DRM driver looks up the memory object by its handle and the memory objects contain GPU address space offsets.

</pre>

====Fences====

* Nouveau driver implements DRM fences with REF control register. See '''nouveau_fence.c:nouveau_fence_new'''.
* Newer Nvidia chips support semaphores. Nouveau driver uses semaphores for fences if they are supported.
* libgcm functions '''SetWriteCommandLabel''' and '''SetWaitLabel''' use semaphores.
* '''SetWriteCommandLabel''' releases semaphore and '''SetWaitLabel''' acquires semaphore.
* Semaphores are placed in VRAM. Nouveau driver creates a small VRAM heap for semaphores. See '''nouveau_fence.c:nouveau_fence_channel_init'''.

====IOCTLs====

=====Context Create=====

* Creates new RSX context
* Allocates VRAM and memory for FIFO buffer
* Needed VRAM size and FIFO buffer size must be known during context creation

=====Context Destroy=====

* Destroys previously allocated context

=====Context Attribute=====

* Changes context attributes

=====Graphic Object Creatre=====

* Create a graphic object either in VRAM or in XDR
* Used to create FIFO command buffers too (only in XDR of course because RSX supoorts FIFO command buffer in XDR only)

=====Graphic Object Destroy=====

* Frees previously created graphic object

=====FIFO Execute=====

* Allows user space applications to execute FIFO commands.
* To avoid copying of buffers allocated by user space to main FIFO command buffer use CALL and RET RSX FIFO commands to execute FIFO commands in buffers allocated by user space.
* Several FIFO command buffers can be submitted at once.

=====Framebuffer=====

* Kernel DRM driver has to implement a frame buffer driver too
* Nouvea driver allocates frame buffer in video RAM and maps it into kernel address space (see '''nouveau_fbcon.c:nouveau_fbcon_create'''). Current ps3fb Linux driver doesn't allocate frame buffer in vide RAM but in system RAM.
* Direct access to video RAM from kernel is very very slow but some of frame buffer functions in Nouvea driver are hardware accelerated. We could do it the same way on Linux and get a hardware accelerated frame buffer this way. Not sure why ps3fb authors didn't add hardware acceleration to frame buffer. The reason why it was not implemnted in ps3fb is because LV1 doesn't create 2D graphic objects needed for 2D hardware acceleration.
* '''lv1_gpu_allocate_memory''' returns LPAR address of video RAM allocated for the RSX context.
* Unfortunately '''lv1_gpu_context_allocate''' doesn't initialize 2D ROP objects but we could use 3D operations to implement 2D ROPs.

===libdrm===

* Add support for RSX DRM to '''libdrm'''

===Test Kernel Module and Program===

* I uploaded here a test kernel module and a test user application: [http://www.gitbrew.org/~glevand/ps3/linux/ps3rsx_kernel.tar.gz] and [http://www.gitbrew.org/~glevand/ps3/linux/ps3rsx_user.tar.gz]
* I used a similar technique for mapping GPU resources into user-space like Linux kernel DRM drivers do it, e.g. Nouveau. But of course everything is very simplified in comparison with Nouveau driver. All GPU resources are mapped to user-space with mmap and there is no data copying between user and kernel space, for performance reasons. Mapping GPU resources into user-space like this is more flexible than IOCTLs.
* '''The purpose of the kernel module and the user application is to test how RSX works, to test FIFO commands and other stuff i reversed from Lv2. It's NOT for end users.'''
* Before loading the kernel module make sure ps3vram kernel module is NOT loaded.
* I used 64kB IO pages for GPU context. 4kB IO page size would be definitely a lot better for that we have to patch LV1. I will add this patch to my ps3mfw tasks for LV1.
* Just load the kernel module and then run the user application.
* The user application maps all context resources and executes some simple FIFO commands, like JMP or SET REF.
* I will add more examples later.
* By default, the kernel module allocates 8MB VRAM, 64kB FIFO and 1MB GART memory. You can change it by using kernel module parameters.
* Take a look at how i made non-contiguous allocated GART memory look contiguous to GPU, kernel-space and user-space.
* The kernel module needs some IOCTLs, e.g. for setting display buffers or flip status, because it can be done ONLY with LV1 calls. I will add it later.

===HRL Buffer===

* Size is 32KB just like AACS specifications prescribes (See AACS Common Specification 3.2.5.2 Host Revocation List Record)
* '''We could replace HRL with an older one in BD drive flash and restore revoked Host Certificates !!!'''

==Device Commands==

===Get Profile (0x11)===

* BD profile can be read with LV1 call '''lv1_send_storage_device_command''' and command '''0x11'''
* LV1 sends SCSI command '''GET CONFIGURATION''' to BD drive with '''requested type 0x0''', '''starting feature number 0x0''' and '''allocation length 0x8'''
* See SCSI command '''GET CONFIGURATION'''

===Auto Request Sense Mode On/Off (0x30)===

* LV1 expects a 4 byte value: 0x0 - On, 0x1 - Off
* can be get/set via GameOS sc0x25C/604: sys_storage_send_device_command(fd of bdvd,0x30,value,4,0,0 )

==SCSI Commands==

===Get Configuration===

</pre>

===Get SS Key===

* By SCSI standard undocumented parameters are used
* '''SCSI Report Key''' command with '''key format 0x3''' and '''key class 0xe0'''
* 8 bytes are returned by BD drive
* Used by VSH

Test with PS3 game disc:
<pre>
# sg_raw -r 8 /dev/sr0 a4 00 00 00 00 00 00 e0 00 08 03 00
SCSI Status: Good

sense buffer empty

Received 8 bytes of data:
 00     00 06 00 00 00 00 00 04                             ........        
</pre>

===Eject Media===

<pre>
sg_raw /dev/sr0 0x1b 00 00 00 02 00
</pre>

===Load Media===

<pre>
sg_raw /dev/sr0 0x1b 00 00 00 03 00
</pre>

===Mode Select 10===

====Enable Buffer Write====

* Uses '''PF 0x1''', '''SP 0x0''' and '''parameter list length 0x10'''
* Uses the following parameter list: '''0x00 0x0e 0x00 0x00 0x00 0x00 0x00 0x00 0x2d 0x6 <buffer id> 0x00 0x00 0x00 0x00 0x00'''
* '''Enables writing to BD drive flash, e.g. to HRL buffer !!!'''

Test with sg3-utils which enables write to HRL buffer:
<pre>
sg_raw /dev/sr0 55 10 00 00 00 00 00 00 10 00 00 0e 00 00 00 00 00 00 2d 06 04 00 00 00 00 00
</pre>

===Write Buffer===

* Used e.g. by Update Manager to send BD firmware to BD drive
* '''Mode 0x5 (Download microcode and save)''' is used e.g. to write HRL to BD drive flash
* '''Mode 0x7 (Download microcode with offsets and save)''' is used e.g. to write BD firmware to BD drive flash

==AACS==

===AACS SPU Module===

* BD player on GameOS uses '''AacsModule.spu.isoself''' (/dev_flash/bdplayer) to perform AACS authentication
* Tested on OtherOS++ 3.55
* Host certificate, host private key and AACS LA public key are stored encrypted with AES-256-CTR in the SPU module and are decrypted when the SPU module is loaded or when it's accessed first. The AES-256-CTR key and IV are in the SPU module too.
* 4.76 uses new Host certificate

====Communication====

* BD player reads '''EID3''' with '''Indi Info Manager 0x17001/0x17002''' services and passes it to SPU module
* '''EID3 is NEVER used in the SPU module although BD player passes it to the SPU module'''
* Data is exchanged with the SPU module through '''SPU In Mbox''', '''SPU Out Intr Mbox''' and a data buffer in XDR memory of size '''0x2000''' bytes.

====Commands====

* The SPU module supports max '''0x78''' (til 4.75, 0x57 since 4.76) commands but not all are implemented
* After a command is finished by the SPU module, it sends the status of the command to PPU through '''SPU Out Intr Mbox'''. Value 0 means success.

==CSS==

===CSS SPU Module===

* DVD player on GameOS uses '''CssModule.spu.isoself''' (/dev_flash/bdplayer) to perform CSS authentication

====Commands====

* The SPU module supports max '''0x25''' commands but not all are implemented
* After a command is finished by the SPU module, it sends the status of the command to PPU through '''SPU Out Intr Mbox'''. Value 0 means success.

=====Generate Host Challenge Key (0x3)=====

* Generates '''0x10''' bytes of '''host challenge key'''

=====Set Drive Key1 (0x4)=====

* Sends '''key1''' of size '''0x5''' returned by DVD drive to the SPU module

=====Set Drive Challenge Key (0x5)=====

* Sends '''0x10''' bytes of '''drive challenge key''' to the SPU module

=====Calculate Host Key2 (0x6)=====

* Calculates '''key2''' of size '''0x5'''

=====Get Host Key2 (0x7)=====

* Returns '''key2''' of size '''0x5'''

=====Set Disc Key (0x8)=====

* Sends Disc Key block of size '''0x800''' to the SPU module

=====Decrypt Sector (0xc)=====

* Decrypts the passed sector

===CSS Salt===

* It's NOT in clear text in the SPU module, it's obfuscated by xoring '''0xDEAF''' (SONY employees have a sense of humor).
* There are 2 bytes for every salt byte

Obfuscated:
<pre>
71 ED 3F A3 DA FE E4 94  40 8C
</pre>

Clear text:
<pre>
F4  10  45  A3  E2

==Remarrying BD Drive on OtherOS++==

===fdm_spu_module.self===

* This SPU module can create either P- or S-Block which are sent to BD drive
* '''EID2''' is passed to the SPU module
* A XDR memory buffer of size '''0x1000''' is passed to the SPU module
* 4 bytes at offset 0x10 of the XDR memory buffer contain the type of block which should be produced by the SPU module
* When the SPU module is finished, the XDR memory buffer contains the needed block
* After the S- and P-Blocks are produced by the SPU module, they are decrypted again but with '''DES''' (CBC mode, key length is 64 bits, initialization vector length is 64 bits) before they are sent to BD drive. S$ny cuts the header and the footer of 16 bytes each from final P- and S-blocks before sending them to drive.

====Block types====

{| class="wikitable"
|-
! Type !! Description !! BD Drive Buffer ID
|-
| 0x1 || P-Block || 0x2
|-
| 0x2 || S-Block || 0x3
|}

===Remarrying===

====Preparations====

* You will need '''ps3dm-utils''' and '''sg3-utils'''
* Dump your '''EID2''' from '''flash''' or with '''ps3dm-utils'''
* First create P- and S-Blocks from your EID2 with kernel module '''fdm_spu_module'''

====P-Block====

Decrypted P-Block (and EID4) contains region settings (see below)

In decrypted P-Block(bytes 0x30 and 0x32) and in EID4(first byte) these bytes match [[Product Code]]:

==VTRM Services==

===Store With Update (0x2003)===

* Used by GameOS BD player to update DRL/CRL hashes

===Retrieve (0x2005)===

* '''Product mode''' is NOT required
* '''0x40''' bytes of data are read from NOR flash, decrypted by SYSCON and returned to the caller
* Used e.g. by GameOS BD player to read SHA1 hashes of DRL and CRL

====DRL and CRL Hashes====

* Written by GameOS BD player during DRL/CRL update
* Read by GameOS BD player
* Hashes are stored encrypted on NOR flash
* Encryption/decryption is done by SYSCON (SYSCON Manager)

Test with ps3dm-utils:
<pre>
# mount dev_flash3

glevand@debian-hdd:~/ps3dm-utils$ sudo mount /dev/ps3vflashe /mnt

=Revoke List=
Crossreference: [http://wiki.gitbrew.org/wikibrew/PS3:HvReverseEngineering#Revoke_List gitbrew::Revoke List]<br />

==LPAR 1 System Call 0x1004A==

* Installs new revoke list in LV1
* LPAR 1 processes can use this syscall to install new revoke lists at runtime
* '''lv2ldr''' is loaded by LV1 and used to verify the passed revoke list
* After lv2ldr is done verifying the passed revoke list, it checks for stop code and if it's '''0xB''' then LV1 replaces the old revoke list with the new one
* If the verification of the revoke list was successfull then LV1 installs new revoke list and replaces the old one in the ISO loader table at address '''0x10100'''

==rvk_list_verifier==

* Stop code 0xB means that the passed revoke list is valid.
