2a6457b6ab Cut down on h files including PointerWrap. 
This makes changes to it a bit faster to build.

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.

3ed2045f6b Add state saving to tertiary kernel modules. 2012-12-28 13:55:25 -08:00

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?

87fcdc9080 Use KERNELOBJECT_MAX_NAME_LENGTH for name length. 
Just avoiding magic numbers, didn't know there was a constant.

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.
 2012-12-09 01:04:53 -08:00
Unknown W. Brackets
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.
 2012-11-30 22:58:42 -08:00
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
Unknown W. Brackets
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?

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.
