SC Manager

• SC Manager cannot be accessed directly by using DM unfortunately (DM discards all requests) but it's used by other services that are accessable through DM
• E.g. Update_Manager services "Read EEPROM" and "Write EEPROM" send requests to SC Manager services "Read EEPROM" and "Write EEPROM"
• SC Manager runs sc_iso.self
• With full HV rights you could patch Dispatcher Manager and enable access to SC Manager from GameOS.

0x9001 - SC Get SRH

struct ss_sc_mgr_get_srh
{
    u8 field0[20];
    u8 res1[4];
    u8 field18[20];
    u8 res2[4];
};

0x9003 - SC Encrypt

• There are 5 different types/kinds of encryption: 1 - 5.

struct ss_sc_mgr_encrypt
{
    u32 type;               /* 1 - 5 */
    u8 res[4];
    u8 field8[16];
    u8 field18[16];
    u64 field28;
};

0x9004 - SC Decrypt

• There are 5 different types/kinds of decryption: 1 - 5.
• Virtual TRM Decrypt Master (0x200E) service uses e.g. decryption type 4.

0x9006 - SC Get Region Data

• This service expects an ID. The valid range of ID is 0 - 15.
• E.g. Update Manager uses this service to retrieve hash and version of some SELFs and firmwares, e.g. lv0 and lv1.

struct ss_sc_mgr_get_region_data
{
    u64 id;
    u64 data_size;    /* max 0x30 bytes */
    u8 data[0];
};

Update Package Type - ID Mapping Table

Update Package Type	ID
1	0
2	2
3	4
4	6
5	7
6	8

0x9007 - SC Set Region Data

• This service expects an ID. The valid range of ID is 0 - 15.
• E.g. Update Manager uses this service to store hash and version of some SELFs and firmwares, e.g. lv0 and lv1.

struct ss_sc_mgr_set_region_data
{
    u64 id;
    u64 data_size;    /* max 0x30 bytes */
    u8 data[0];
};

0x900B - SC Read EPROM

• There are 2 ways to access SC EPROM: NVS Service and Device Access Service.
• NVS Service uses Block ID and Block Offset.
• Not all EPROM offsets can be accessed through SC Manager.

struct ss_sc_mgr_read_eprom
{
    u32 offset;
    u8 res1[4];
    u32 nread;               /* max 0x100 bytes */
    u8 res2[4];
    u64 buf_size;
    u8 buf[0];
    /* here follows buf */
};

EPROM Offset - Block ID and Block Offset Mapping Table (NVS Service)

EPROM Offset	Block ID	Block Offset	Notes
0x48000 - 0x480FF	0x00	0x48000 - 0x480FF
0x48800 - 0x488FF	0x01	0x48800 - 0x488FF
0x48C00 - 0x48CFF	0x02	0x48C00 - 0x48CFF
0x48D00 - 0x48DFF	0x03	0x48D00 - 0x48DFF
0x2F00 - 0x2FFF	0x10	0x2F00 - 0x2FFF	"Industry Area" aka OS Version Area
0x3000 - 0x30FF	0x20	0x3000 - 0x30FF	"CS Area"
All other offsets	Invalid	Invalid

0x900C - SC Write EPROM

struct ss_sc_mgr_write_eprom
{
    u32 offset;
    u8 res1[4];
    u32 nwrite;
    u8 res2[4];
    u64 buf_size;
    u8 buf[0];
    /* here follows buf */
};

0x900E - SC Get Status

Here is what the service returned on my fat PS3:

0x00 0x00 0x00 0x03 0x00 0x00 0x00 0x00 0xC0 0x00 0x00 0xFF 0x00 0x00 0x00 0x00

So, version is 0x00000003 and mode is 0xC00000FF.

struct ss_sc_mgr_get_sc_status
{
    u32 version;
    u8 res1[4];
    u32 mode;
    u8 res2[4];
};

0x9011 - SC Binary Patch

• This service is used by Update Manager to send a new SC firmware version to SYSCON.

SC Isolation DMA Buffer Header

struct sc_iso_header
{
    u32 seqno;
    u32 mbmsg;
    u32 cmd;
    u32 cmd_size;
    u8 cmd_data[0];
};
