bf652e4f46 Don't report for <= 4 sized option parameters. 
Also don't crash in sceKernelCreateVTimer(NULL, NULL).

933c8abb55 Check kernel object types when looking up ids. 
Some games misuse it, need to return an error.

77b0688d92 Recalculate numWaitThreads all the time. 
Before, it could go negative by having a thread woken a second time
(e.g. because of a delete) before it actually scheduled and woke up.

ac9e936ba8 Fix sema and event flag refer to check size. 
If it's zero, write nothing, just like the others.

9ce8c07530 Reschedule the timeout event on callback end. 
Darn, missed that 3 times before I caught it.

0918ec8598 Return negative for UnscheduleEvent(). 
It usually won't be, but it could be negative.

Also some other minor warnings.

fe60677f75 Make mutexes handle callbacks better + before. 
Mutex and semaphores (but NOT lwmutexes) call callbacks before attempting
the lock, but only if it would not generate errors.

Have not yet tested other wait types.

eace0e75c1 sceKernelWaitSemaCB() should run callbacks first. 
Patapon 2 gets back to the menu with this.

e133d33167 Don't re-wake a thread already woken by delete.

2a6457b6ab Cut down on h files including PointerWrap.

1cb7a88137 Don't use a dynamic string for wait debugging. 
Happens in release, and shows up on the profiler.
Not huge, but should save ~0.5% of cpu time.

305c41c932 Prevent duplicate waiting threads in sema/mutex. 
If something did a tight loop of a short wait/timeout, it might end
up getting on the waitingThreads list multiple times.

Eventually this caused a massive performance problem.

bcecd881b1 Savestate cleanup + be more careful with vectors. 
For some reason I debugged it going into std::string so I just made
them all more explicit which fixed everything.

595759ef78 Implement a factory for kernel objects. 
Couldn't think of a better way to do this, maybe there's some fancy
one I don't know about.

Also finished up a couple left over kernel objects.

Maybe a quarter the way there?

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.

45258bb61f Cleanup behavior in sceKernel*EventFlag() funcs.

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.

Unknown W. Brackets
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.
 2012-11-30 22:58:41 -08:00

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.
