SceSblSmCommForKernel

sceSblSmCommStopSmForKernel

Version NID
0.931-3.60 0x0631F8ED

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

int sceSblSmCommStopSmForKernel(SceSmSchedRequestId req_id, status_handler *pStatusHandler);

sceSblSmCommStartSmFromDataForKernel

Version NID
3.60 0x039C73B1 
int sceSblSmCommStartSmFromDataForKernel(SceBool priority, const char *sm_self, SceSize sm_self_size, int cmd_id, SceSblSmCommContext130 *ctx_130, SceSmSchedRequestId *req_id);

sceSblSmCommStartSmForKernel

Version NID
0.931-3.60 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. 

int sceSblSmCommStartSmForKernel(SceBool priority, void *sm_self, SceSize sm_self_size, SceSblSmCommContext130* ctx_130, SceSmSchedRequestId *req_id);

sceSblSmCommStartSm_ForKernel
