bb10140728 Oops, event flags weren't always deleting properly. 
Added some comments to explain why removal from waitingThreads is
deferred.  Also had to move things around so the right outBitsPtr
is always written to on timeouts.

67f7f6b05d Oops, these flags can be or'd together of course. 2012-12-14 23:24:04 -08:00

45258bb61f Cleanup behavior in sceKernel*EventFlag() funcs. 
Biggest change is just that sceKernelSetEventFlag() rescheds.

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.

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.

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.

619a9906de Remove threads from semaphores when they timeout. 
This makes wait tests *almost* pass.  There's some timing
related issues left, though.

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

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

This makes threads/semaphores *almost* pass.
It's now failing from sceKernelStartThread() or something, though.

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.
