SC Manager

From PS3 Developer wiki
Jump to: navigation, search
  • 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.
 note: inside ss_server2.fself

0x9001 - SC Get SRH[edit]

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

0x9003 - SC Encrypt[edit]

  • 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[edit]

  • 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[edit]

  • 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[edit]

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

0x9007 - SC Set Region Data[edit]

  • 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[edit]

  • 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)[edit]

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[edit]

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[edit]

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];
};
mode[3] == 0xFF (SC_INIT_FLAG_NON_PRODUCT_MODE)
clrlwi mode, 24 != 0 (SC_INIT_FLAG_NEED_PERSONALIZE)

0x9011 - SC Binary Patch[edit]

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

SC Isolation DMA Buffer Header[edit]

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