292a9ea567 Clear module text and bss on unload. 
Text is set to break instructions, data/bss to -1.  Matches results on a
PSP.

ef4847b6f5 Don't double decrease g_inCbCount. 
Happened when a thread was deleted, it seems like.  Fixes #6542.

0078faef8b Fix some log semicolons that might affect logic. 
But, these should all be right.

b68ad3844e Simplify __KernelReSchedule(). 
It no longer needs all these checks, and we can Advance within callbacks,
interrupts, etc. safely.

0edeb085ab Allow rescheduling within callbacks. 2014-06-28 14:58:56 -07:00
Unknown W. Brackets
10096b94f2 Correctly remember callback status when sleeping. 
If a callback triggered right away after a sceKernelSleepThreadCB(), it
would trigger the "current callback" and remember callback status as
false, instead of true (since it was set later.)

This corrects that by ignoring it if both are set.

5ab3750186 Reduce the thread switching cost. 
Maybe it was actually too high.  Some tests fail with it that high.

4626e63294 Wake good pri threads immediately from delays. 2014-06-24 00:45:38 -07:00
Unknown W. Brackets
118736ff75 Don't eat extra cycles when idling. 
Rescheduling between threads takes about 3000 cycles, but that's not true
for both sides of e.g. a delay.

Fixes #6409 (assuming 60fps is what a PSP gets.)

392edb4f84 Eat some cycles when switching threads. 
There's a cost and it seems to be at least this much.  Matters for
Wipeout Pure when callbacks are allowed to wait.

e8803c4e9b Improve sceKernelDelayThread() timing. 
A delay of 0 never reschedules, actually, unless there's a better priority
thread.  A greater delay depends on if a >= or similar check matches, but
generally is at least 200us.

It seems like this actually completes in at least another 10-20us.

This should be usable from sceIo as well.

641064f0bc Consistently use MIPS_REG_V0 for return values. 
This way all instances are a lot easier to search for (was trying to find
where we were writing an incorrect value to v0, turns out to be callback
related of course.)

48fd33b201 Remove callback return injection and related. 
With paused waits, this is no longer correct.  Callbacks still don't allow
waits inside callbacks yet (they should.)

c9b037815f Reschedule instead of switching to delayed threads. 
This will hopefully take care of #5263, and might fix other issues too.
If a thread goes into a wait, it may reschedule right into an interrupt.

In this case, it would've been switched back to, and woken up early.

21cdcb5c0d Force rescheduling within a callback.

cb4e72058a Report usage if callback "injection." 
These are generally giving incorrect results, but it will help to know
what games are triggering it.

1a38f6fa7d Properly remove terminated thread from ready queue. 
If we change the priority first, we'll remove from the wrong priority
level, oops.  Gotta change afterward.

Should improve Darkstalkers Chronicle: The Chaos Tower.

183b4cb45c Add a static method for creating PSPPointers. 
This is still kinda ugly, but the assignment thing was just too ugly, I
couldn't do it anymore.

7dedf54bc3 Always resched in thread queue rotation. 
It might be time to reschedule anyway, some games call this in a loop with
an empty queue.

May help Harukanaru Toki No Naka de Hachiyoushou (#4669.)

To reduce overhead/improve perf.  Actually, it used to be only the current

Some, like sceMpegRingbufferPut(), we don't, since... it's complicated.
