sceSblSmCommCallFunc_ForKernel

Version NID
0.931.010 0x4960DF9E
1.692.000-3.740.011 not present

This function is just a 4-argument wrapper for #sceSblSmCommCallFuncForKernel. 

typedef struct sceSblSmCommCallFunc_Param {
    void *pData;
    SceSize dataSize;
} sceSblSmCommCallFunc_Param;

int sceSblSmCommCallFunc_ForKernel(SceSmSchedRequestId req_id, SceUInt32 func_id, SceUInt32 *pResponse, sceSblSmCommCallFunc_Param *pParam);

sceSblSmCommStopCommForKernel

Version NID
0.931.010 0xC35FB95A
1.692.000-3.740.011 not present 
int sceSblSmCommStopCommForKernel(SceSmSchedRequestId req_id);

sceSblSmCommStartSmForKernel

Version NID
0.931.010 0x7863A0CC
1.692.000-1.810.021 not present
3.600.011-3.740.011 0x7863A0CC

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

The following conditions must be met in order for this function to be called successfully: - In kernel thread. - In kernel context.

Calling a function without satisfying the conditions freezes the system. 

int sceSblSmCommStartSmForKernel(SceBool priority, const char *sm_self_path, SceSblSmCommContext130 *ctx_130, SceSmSchedRequestId *req_id);

sceSblSmCommStartSm_ForKernel

Version NID
0.931.010-1.800.071 0x992BB9DB
3.600.011-3.740.011 not present 
int sceSblSmCommStartSm_ForKernel(SceBool priority, const char *path, SceBool some_bool, int unk_a4, int unk_a5, int unk_a6, SceSblSmCommContext130 *pCtx, SceSmSchedRequestId *pReqId);

sceSblSmCommStartSmFromDataForKernel

Version NID
0.931.010-1.800.071 not present
3.600.011-3.740.011 0x039C73B1 
int sceSblSmCommStartSmFromDataForKernel(SceBool priority, const void *sm_self, SceSize sm_self_size, int cmd_id, SceSblSmCommContext130 *ctx_130, SceSmSchedRequestId *req_id);

sceSblSmCommStopSmForKernel

Version NID
0.931.010-3.740.011 0x0631F8ED

This function calls sceSblSmCommCallFuncForKernel with -1 (0xFFFFFFFF) as func_id and then calls sceSblSmSchedProxyWaitForKernel. 

int sceSblSmCommStopSmForKernel(SceSmSchedRequestId req_id, status_handler *pStatusHandler);
