== | == 0x18000 - DM (Dispatcher Manager) == | ||
*Dispatcher Manager runs in Process 3. | |||
*When SLL (Secure LPAR Loader) creates GamesOS LPAR and loads it, it also creates a VUART with port number '''10''' owned by GameOS using a service provided by Dispatcher Manager (0x18001 - Construct Service Port). | |||
*Dispatcher Manager communicates with GameOS through this VUART. It opens the file '''/proc/partitions/<LPAR id>/vuart/10'''. When the file '''/proc/partitions/<LPAR id>/vuart/10''' is opened by Dispatcher Manager, the Hypervisor creates a peer VUART which is connected to the GameOS's VUART 10. | |||
*After that Dispatcher Manager reads requests from this VUART sent by GameOS and dispatches these requests to services (functions) provided by Hypervisor Processes through sockets. '''Through VUART and Dispatcher Manager, the GameOS LPAR has access to all services provided by Hypervisor Processes.''' | |||
*However, the services provided by Hypervisor Processes are protected by Security Policy Manager (SPM). Before Dispatcher Manager routes the requests from GameOS to these services, it consults SPM (by using 0x11001 service of SPM) and checks if the GameOS has access rights to the requested service. If not then the request is not routed. | |||
*DM overwrites the LAID sent in SS packet header with the LAID of the LPAR that sent the request. So, no matter what LAID you send in SS packet header, it will be always overwritten with the correct one by DM. That is the reason why e.g. USB Dongle Master Key cannot be decrypted by GameOS without patching DM. But with HV access rights, DM can be easily patched and access to SYSCON can be gained. | |||
*Linux LPAR doesn't have a VUART communication link to Dispatcher Manager. | |||
*I tested VUART 10 on GameOS with PSGroove and it's there. | |||
*On GamesOS, '''_ss_multiplexer''' accesses DM (VUART 10) | |||

*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 | |||

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 !!! 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. | |||

== 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. | |||

== 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. | |||

*''' | *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)'''. | |||

= | = 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 | |||

== 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 !!! | |||
*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. | |||

SYSCON MMIO registers can be accessed on Linux with a driver using lv1_undocumented_function_114, e.g. '''ps3sbmmio'''. | |||
Use ps3sbmmio device driver carefully, an access at some addresses could shutdown your PS3. | |||
==Packet Header== | |||
* Size is '''0x10'''. | |||
<pre> | |||
struct sc_hdr { | |||
uint8_t service_id; | |||
uint8_t version; /* must be 1 !!! */ | |||
uint16_t transaction_id; /* returned in response */ | |||
uint8_t res[2]; | |||
uint16_t cksum; /* checksum of first 6 header bytes */ | |||
uint32_t index; /* SYSCON index: 0-4 */ | |||
uint16_t payload_size[2]; /* body size */ | |||
}; | |||
</pre> | </pre> | ||
==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 :) | |||

Crossreference: [http://wiki.gitbrew.org/index.php/PS3:HvReverseEngineering#Gelic_Device gitbrew.org::Gelic Device] <br /> | |||
==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. | |||
==== Parameters ==== | |||
r3 - command (16 bits) | |||
r4 - effective address of command data buffer | |||
r5 - size of command data buffer | |||

== | == 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. | |||

===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> | <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> | </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) | |||

* 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. | |||

= | * 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. | |||

* '''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==== | |||

==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 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==== | |||
Received 8 bytes of data: | * Every context has its own one main FIFO command buffer which is NOT accessible directly by user space. | ||
00 00 06 00 00 00 00 00 04 ........ | * 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. | ||
</pre> | * 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. | |||

====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. | |||
