Editing SC Manager

[[Category:Software]]
*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  ===

<pre>

{
    u8 field0[20];
    u8 res1[4];
    u8 field18[20];
    u8 res2[4];
};
</pre>

=== 0x9003 - SC Encrypt  ===

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

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

=== 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'''.

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

=== 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'''.

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

=== 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.

<pre>
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 */
};
</pre>

=== 0x900C - SC Write EPROM  ===

<pre>
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 */
};
</pre>

=== 0x900E - SC Get Status ===

Here is what the service returned on my fat PS3:
<pre>
0x00 0x00 0x00 0x03 0x00 0x00 0x00 0x00 0xC0 0x00 0x00 0xFF 0x00 0x00 0x00 0x00
</pre>

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

<pre>
struct ss_sc_mgr_get_sc_status
{
    u32 version;
    u8 res1[4];
    u32 mode;
    u8 res2[4];
};
</pre>

=== 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  ====
<pre>struct sc_iso_header
{
    u32 seqno;
    u32 mbmsg;
    u32 cmd;
    u32 cmd_size;
    u8 cmd_data[0];
};
</pre>
