SceSblSmCommForKernel

sceSblSmCommStopSmForKernel

Version NID
1.69-3.60 0x0631F8ED

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

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

sceSblSmCommStartSmFromDataForKernel

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

sceSblSmCommStartSmFromFileForKernel

Version NID
3.60 0x7863A0CC 
int sceSblSmCommStartSmFromFileForKernel(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.

sceSblSmCommCallFuncForKernel

Version NID 1.69-3.60 0xDB9FC204

sm_comm_context is described more here

f00d_resp comes from Request Buffer from offset 0x08

gc_param is generated by game card and has value 0x01 

typedef struct SceSblSmCommGcData {
	int unk_0; // 1
	int gc_command;
	char gc_buffer[0x800];
	int gc_param;
	int length;

	unsigned int unk00;
	unsigned int unk04;
	unsigned int unk08;
	unsigned int unk0C;
	unsigned int unk10;
	unsigned int unk14;
