SceDeci4pDbgpForDriver

_sceDbgpStartSupportingAppObject

Version NID
0.940.I-0.945 0x72AE00B7
0.990.030-3.730.011 not present

Seemingly replaced by _sceUlobjMgrStartSupportingUserlevelObject. 

// On success, *ppDebugInfo receives a pointer to a 0x81000 bytes memblock
SceInt32 _sceDbgpStartSupportingAppObject(ScePVoid** ppDebugInfo);

_sceDbgpStopSupportingAppObject

Version NID
0.940.I-0.945 0x11908EDB
0.990.030-3.730.011 not present

Seemingly replaced by _sceUlobjMgrStopSupportingUserlevelObject. 

SceInt32 _sceDbgpStopSupportingAppObject(void);

sceDbgpGetDTraceBreakpointHandlerForDriver

Version NID
0.940.I-0.945 not present
0.990.030-3.730.011 0x01D7C7BF

Version NID
0.940.I-0.945 not present
0.990.030-3.730.011 0x0509AC51

In FWs 0.990.030-0.995, this handles bkpt #0x90. Seems to handle breakpoints with code < 0x7F in FW 3.60. 

void sceDbgpSetDTraceBreakpointHandlerForDriver(SceDbgpBreakpointHandler* handler);

Version NID
0.940-1.000.041 not present
2.000.081-3.730.011 0x7251789E

Sets handler for bkpt #0x90. 

void SceDeci4pDbgpForDriver_7251789E(SceDbgpBreakpointHandler* handler);

SceDeci4pDbgpForDriver_9CD5EE8C

Version NID
0.940-1.81 not present
2.000.081-3.730.011 0x9CD5EE8C

Get handler set by SceDeci4pDbgpForDriver_7251789E. 

SceDbgpBreakpointHandler* SceDeci4pDbgpForDriver_9CD5EE8C(void);
