libretroadmin f1208a7a5a Make threading lock-free 
The core and the headless tools no longer use mutexes, condition variables,
spinlocks, std::atomic, std::thread or volatile flags. Threads hand off through
libretro-common's retro_atomic and rthreads plus a few small pieces on top of
them in Common/Thread: Thread, MpscQueue, EventCounter, ParkingLot waits and
ReaderGate. Every wait blocks until it's woken; nothing polls on a timer.

State that only one thread touches just loses its lock. The PSP filesystem,
sceIo and the savedata dialog now belong to the emulation thread: async reads
and writes run when they're queued and complete later in emulated time, and
the IO and savedata threads are gone. The friend finder only talks to the
adhoc server and hands what it gets to the emulation thread. GPU init always
runs on the thread that starts the game.

The Vulkan render and compile queues, pipeline and render pass caches, delete
list and SPIR-V cache, the GL render queue, the software renderer's jit caches,
the file loader caches, the web debugger, UPnP, input, savestates, logging and
the GE debugger all hand off through queues and atomics. The IR jit's spinning
profiler thread goes.

A CPU thread with nothing to run now sleeps until work is queued instead of
spinning. Headless with --debugger waits for a client while stopped, and ends
the run once every client that connected has left. Web server shutdown keeps
servicing the CPU queue until the server has finished.

Henrik RydgårdandClaude Opus 5.5 71bc3187db Vulkan: Reload the shader cache after a device restore 
DeviceLost saves the cache and clears everything, and the next save wrote
back only what was drawn since, so each Android background/resume cycle
shrank the cache.

Henrik Rydgård d31ba393af Don't load the shader cache on a separate thread - all it does is already async 2023-09-24 10:53:23 +02:00

Henrik Rydgård be63ce3a4a Minor refactor allowing getting the GPU profile string outside games 2023-08-03 16:31:20 +02:00
Henrik Rydgård 05b6bbdc56 Add a trivial profiling tool to the OpenGL backend - meaasure the time it takes to run a frame of commands. 
Accessed from the in-game dev menu just like the Vulkan frame profiler.

With this we can easily see that actually submitting the GL commands is often the bottleneck on old
devices like a Galaxy S3.

Henrik Rydgård effbe6376a Remove an unused VulkanPushBuffer. 
Saves about 0.75MB of VRAM, but mainly just to clean things up.

I think I meant to use this one instead of grabbing the one from
DrawEngine in the TextureCache.

Unknown W. Brackets 8a5f07b860 Vulkan: Don't cache vulkan_ with draw context. 
Since we can get the VulkanContext cheaply from the draw context, it's
easier to make sure things stay up to date.

Unknown W. Brackets cebcfb1bbd GPU: Use old frame when presenting a skip. 
If we flip using a skipped frame, we may show an even older frame causing
weird flickering.

Unknown W. Brackets 40ca49d0e3 GPU: Cancel shader preload on shutdown/lost. 
Otherwise, we could've ended up with shaders loading after or during the
lost event, and dense hash map corruption.

Henrik Rydgård 614cabb115 Implement pipeline/shader cache for Vulkan, to avoid shader compile stutters on second and subsequent runs. 
The raw pipeline cache got pretty large. Instead, store IDs like GL.

There's still a disabled option to store the pipeline cache objects.
