SceSblSmCommForKernel

sceSblSmCommStopSm

Version NID
1.69 0x0631F8ED
3.60 0x0631F8ED

This function calls sceSblSmCommCallFunc with -1 as command_id and then calls sceSblSmSchedProxyWait. 

int sceSblSmCommStopSm(int id, int result[2]);

sceSblSmCommStartSmFromData

Version NID
1.69 0x992BB9DB
3.60 0x039C73B1 
int sceSblSmCommStartSmFromData(int priority, const char *sm_self_data, int sm_self_size, int num1, SceSblSmCommContext130 *ctx_130, int* id);

sceSblSmCommStartSmFromFile

Version NID
3.60 0x7863A0CC 
int sceSblSmCommStartSmFromFile(int priority, char* sm_self_path, int num1, SceSblSmCommContext130* ctx_130, int* id);

Priority is binary: 1 = low, 0 = high. Running a high priority SM module while a low priority one is currently running will suspend it.

sceSblSmCommCallFunc

Version NID
1.69 0xDB9FC204
3.60 0xDB9FC204

sm_comm_context is described more here

f00d_resp comes from Request Buffer from offset 0x08
