3d57a4c838 Cleanup some wrappers now that rescheds defer. 2012-12-09 01:04:54 -08:00
Unknown W. Brackets
5e8aa4c071 Implement deferred rescheduling/callbacks. 
This way most HLE functions can be wrapped normally.  Hurray, sanity.

fda41752e8 Simplify the API for HLE funcs to do callbacks. 
__KernelWaitCurThread() already (ultimately) calls __KernelCheckCallbacks.

1a77b22e3a Implement priority signaling for semaphores. 2012-12-09 01:04:49 -08:00
Unknown W. Brackets
a67505761e Mutexes and semaphores were rescheduling twice. 
This was causing it to "jump" the correct thread and go to the next.

998104e2eb Consider threads still waiting until they wake. 
This seems to match the actual behavior of timeouts much better.

48c5efd0c2 Match hw timing of mutex/sema timeouts better. 
Affects some tests passing/not passing due to minor timing issues, ugh.

7164638799 Allow semaphores with waiters to signal. 
If the max is 1, but there's 1 waiting, it's okay to signal 2.
Really, the final result is what matters.

3ab41e515d Mutexes and semaphores don't always reschedule. 
It's just the normal rescheduling happening.  Previous tests weren't
correct.

Also some minor cleanup.

d3f2d9d10b Use u64 here to avoid warnings, better precision. 
The timeout value is u32 anyway, so an int was already a loss.

b71d998a20 Broadcast a threadend event to wake mutexes. 2012-11-20 02:20:16 -08:00
Unknown W. Brackets
8da2fb074c For mutexes/semaphores, register a global timer. 
Instead of leaking one per each.  Should be faster.
Since we can only wait on one thing per thread at a time, this is fine.

a81c138004 Create and Delete LwMutex funcs. 2012-11-20 02:20:15 -08:00
Unknown W. Brackets
619a9906de Remove threads from semaphores when they timeout. 
This makes wait tests *almost* pass.  There's some timing
related issues left, though.

fd41851503 Implement timeouts on semaphores too. 2012-11-20 02:20:14 -08:00

40a6ebfabe Fix sceKernelCancelSema() to handle any negative. 
So the test isn't failing.

This is what the PSP does.

306274ffdf Fix iterator in sceKernelSignalSema(). 
I'm sure we dont' want to change s.

f37dd7fefe Fix $v0 on wrong thread in semaphore funcs. 
Need to RETURN() prior to switching threads or it will write to the
wrong thread, oops.

33559d23db sceKernelDeleteSema() not returning 0? 
Seems to be a bug outside this func, adding a comment at least.

b58032039b Cleanup sceKernel semaphore funcs. 
Remove some duplication of code so it's cleaner.
 2012-11-11 18:54:06 -08:00

a69fd56573 Implement sceKernelCancelSema() based on jpcsp. 
Don't have any tests/users, but this jpcsp's behavior seems sane.

e7b6487c4e Wrap sceKernel DeleteSema and CancelSema. 
Also fix copy/paste mistake from SignalSema func.

70809bf1f5 Make sceKernelDeleteSema() resume waiting threads. 
This makes threads/semaphores *almost* pass.
It's now failing from sceKernelStartThread() or something, though.

deab1c21b7 Fix sceKernelSignalSema(). 
Handle numWaitThreads and currentCount more correctly.
Well, I'm not 100% sure it's totally right now but it matches the test.

3acca0f941 Fix crash in sceKernelReferSemaStatus. 
This was crashing threads/semaphores, and also PQ2 (and maybe other games.)
Note: threads/semaphores still not passing.
