bf89c01215 When atrac3+ decoding fails, stop decoding silently-ish instead of decoding garbage, spamming the log 2013-10-21 23:10:30 +02:00
Unknown W. Brackets
f5e0d80ead Pass arguments to root threads same as regular. 
Before it would have issues or crash if the args were > 256 bytes.
Fixes Ys 1 & 2 Chronicles.

e06889069c Don't use the destructor to free thread stacks. 
If we do, kernelObjects.clear() will trash perfectly good memory on
loading a state.  I guess it also makes shutdown slower.

Fixes #4186.

b928f50353 Cleanup sceKernelRegisterExitCallback() per tests. 2013-09-29 01:10:07 -07:00

a7ec139b5a Savestate the exit callback, reporting. 
Seems like LoadExecForUser_362A956B() uses it, so we need to save it.
I have no confidence that function works correctly, so let's report it.

50e9e45d65 Check version in each DoState() func. 
They bail on PointerWrap error or bad version.

b898e397aa Correct sceKernelGetThreadStackFreeSize(). 
It was always returning 0.

0f7ac377cd Offset the root thread's stack by arg size. 
Otherwise it'll just overwrite, right?

ccf021cef0 Return a negative error code in __KernelGetWaitID. 
This way we can use 0 as a proper wait id.

a3637a1cad Set the low mystery bits of the thread attr. 
Tests on PSP show this, and I can't find a way to not have them set.
But I don't really know what they mean.

Anyway, since you can refer the status, you can see them, may improve
compatibility.

0af3c50924 Eat cycles after creating a thread. 
Improves things on some tests, should be more accurate.
Creating a thread sure takes a long time.

64b75ed3ff Decentralize callback registration. 
Callbacks are always tied to THEIR thread, and the registration was all
based on the current thread which is just not the right way.
 2013-09-09 00:21:15 -07:00
Unknown W. Brackets
94e88943d8 Keep a single list of pending callbacks. 
Doing it per type only meant that we'd incorrectly call a callback twice
if it was notified by e.g. scePowerRegisterCallback() and
sceKernelNotifyThread(), which isn't what's supposed to happen.

1bf974aff6 Implement VPL/FPL callback handlers. 
Smells like time to refactor, there are less differences than I expected.

648dd5f154 Don't allow sceKernelWakeupThread() on cur thread. 
I don't know why you wouldn't allow this, but the PSP firmware doesn't.

83bc12ea08 Reschedule in sceKernelReferThreadStatus().

7ac67a8931 Add a function to walk the stack, not yet perfect. 
Could use improvements, but with a decent symbol table does very well so
far in the games I tested it in.
