b04e5925d2 Add a scheduling stress test to TestThreadManager.cpp. 
Was hoping to find the cause of the issue I looked at in #15431

2479d52202 Global: Reduce includes of common headers. 
In many places, string, map, or Common.h were included but not needed.

55c11425e4 softgpu: Use persistent bin task state. 
It's constant, so it's better to avoid the copying and allocation.  A
small win, but removes new from the profile.

dffc333120 softgpu: Avoid thread ordering hazard. 
Must run the primitives in the right order.  No shortcutting allowed.

7c7340e338 ThreadManager: Check for exchange failure. 
Even if expected stays null, since it's weak assume it can fail.

f9a7ad3e3d ThreadManager: Use separate pool for IO blocking. 
This prevents starving the compute pool (which may be used very regularly
parallel loops or other tasks) if the IO operations are slow.

8b5173350f ThreadManager: Make TaskType a property of a Task. 2021-12-05 21:01:49 -08:00
Unknown W. Brackets
12b790bb81 ThreadManager: Protect against teardown hang/leak. 
Make sure we lock during canceled checks/updates, and also try to free
tasks queued on threads that didn't end up running.
 2021-11-27 08:57:19 -08:00

de9a4dcede ThreadManager: Lock notify on global queue add. 
Otherwise, it's possible the chosen thread might not wake up, and then it
may wait for another task to be enqueued - potentially causing a hang.
 2021-11-27 08:57:19 -08:00
Unknown W. Brackets
d15af6e9d9 ThreadManager: Use atomic task optimistically. 
This makes EnqueueTaskOnThread take priority as well.
Gives about 1% improvement in softgpu, reducing overhead a bit.

4f85b8b2ef Threading: Remove a level of indirection from Promise and Mailbox. 
Makes using small copyable or POD objects in these more efficient, and if you want
to you can just put a pointer or smart pointer in there, which will
effectively do the same thing as the old setup.

Common: UWP buildfix. 
Just use SetThreadDescription() directly, assuming new enough Windows.

9f1c9b9963 Buildfix 2021-11-13 18:12:09 +01:00
Henrik Rydgård
6e1455fd55 Use the "new" API SetThreadDescription to set thread names on Windows. 
Mainly useful in debugging and profiling tools. Using the new function helps
modern debugging/profiling tools like Superluminal which don't support the
old exception method.

(Is there any old tool left that might be a reason we'd want to do both?)

02a24cdb7d Fix black screen on multiple libretro content loads. 
Moves ThreadPool teardown to retro_unload_game. Gives ThreadPool threads some breathing room to terminate before game load starts spamming it with tasks.
