and you can use the GPIO bits to check for display enable :)


What is the port for checking display enable?

Do you know the value for the standby event? The suspend even doesn't catch it when you hold the power switch for 3 seconds.

Here I've found scePowerIsRequest functions that return 1 if you try to shutdown or suspend the PSP in the both cases ( Power switch and scePower* functions )!
I've also finded scePowerCancelRequest function, I've tried it but doesn't works, maybe there's something to do to get it working!
If I'm right with this you can resolve "all" your problems...
Here is the asm of scePowerCancelRequest
Code:

scePowerCancelRequest:
   0x00002B30: 0x27BDFFF0 '...'' - addiu      $sp, $sp, -16
   0x00002B34: 0xAFBF0004 '....' - sw         $ra, 4($sp)
   0x00002B38: 0x0C0016D2 '....' - jal        sceKernelCpuSuspendIntr
   0x00002B3C: 0xAFB00000 '....' - sw         $s0, 0($sp)
   0x00002B40: 0x3C040000 '...<' - lui        $a0, 0x0
   0x00002B44: 0x24850258 'X..$' - addiu      $a1, $a0, 600
   0x00002B48: 0x8CB00028 '(...' - lw         $s0, 40($a1)
   0x00002B4C: 0xACA00028 '(...' - sw         $zr, 40($a1)
   0x00002B50: 0x0C0016D6 '....' - jal        sceKernelCpuResumeIntr
   0x00002B54: 0x00402021 '! @.' - move       $a0, $v0
   0x00002B58: 0x02001021 '!...' - move       $v0, $s0
   0x00002B5C: 0x8FBF0004 '....' - lw         $ra, 4($sp)
   0x00002B60: 0x8FB00000 '....' - lw         $s0, 0($sp)
   0x00002B64: 0x03E00008 '....' - jr         $ra
   0x00002B68: 0x27BD0010 '...'' - addiu      $sp, $sp, 16

Anyway, can be the args ( a0-1-2-...) be passed directly to sceKernelCpuSuspendIntr?
In this case the scePowerCancelRequest funct has to reiceve 2 args, right?

EDIT:
Sorry, sceKernelCpuSuspendIntr is void so...

AFAIK by the time you can use any of the above functions, the suspend process is already underway and any running game would have made preparations to suspend. Only the sysevent gets called before applications are aware of it.

scePowerCancelRequest only cancels hw requests, ie from the power switch. It doesnt cancel software requests, ie. calls from scePowerRequestStandby, scePowerRequestSuspend, scePower_driver_2875994B, & scePowerRequestColdReset.

If you look at the asm, it only zero's one global var (the hardware request), another var controls the software requests.

Does that mean there's a more efficient way to cancel a power switch suspend that using a sysevent? Because I only want to cancel the power switch event and not the idle timeout suspend. I have to make additional checks for this in my app when using the sysevent.

I tried to call the cancel request in the power callback for power switch pushed but it doesn't work. It still gets suspended.
