Fixes a major preformance regression in Skies of Arcadia during
battle transisions.
I had plans for a more advanced version of this code after 5.0,
but here is a minimal implemenation for now.
|
|
This pr fixes another regression that happened after pr #3165 was merged. The shadows in mario baseball should now work again.

Remove the restriction to use efb copies only once as partial update
|
|
This is an oversight from pr https://github.com/dolphin-emu/dolphin/pull/3266 . Thanks to degasus for pointing this out.
It's possible that MAX_TEXTURE_BINARY_SIZE can be optimised, but i wanted to play it safe considering the 5.0 stable release.
|

I'm not entirely sure what is happening, but this optimisation is causing an issue in Sonic Riders: Zero Gravity. Apparently the issue would also be fixed by PR#3747, but this PR should also fix similar issues.
Games that use partial updates might get slower with this, so some performance regression testing would be nice. Games like New Super Mario Bros, RS2, Zelda TP and Silent Hill. Testing with high graphics settings makes sense, since this would mostly end up in more work for the GPU.

- remove an outdated comment about the efb to ram and scaled efb restriction
- when upscaling efb copies, mark the new texture as efb copy
- dx12 fixes for the src box, especially the number of layers for 3D

target texture, not just the binary size.
This should get Donkey Kong Country Returns characters to be as broken as they should be. They will be fixed in a later pr.
Expected result is:
efbtex: characters are always flickering or invisible, no matter what scaling or IR setting
efb2ram: characters are always working properly at 1xIR, no matter what scaling or IR setting

Avoid the "Memory stride too small" assert
|
|
Also remedies places where the video backends and core rely on things
being indirectly included.
|
|
This was causing crashes/driver resets when odd-dimension textures were
being loaded, due to the size we were uploading being larger than the size
of the higher-level texture calculated by the runtime.
|
|
EFB2Tex still has no idea what to do with these weird textures so we
simply disable EFB2Tex when one is encountered.
|
|
TextureCache, fix an incorrect assert.

Approximately three or four times now, the issue of pointers being
in an inconsistent state been an issue in the video backend renderers
with regards to tripping up other developers.
Global (ugh) resources are put into a unique_ptr and will always have a
well-defined state of being - null or not null

This hopefully allows to use partial texture updates with strided efb copies that start at the same offset as the loaded texture
|
|
|
|
Texture updates have been moved into TextureCache, while
TMEM updates where moved into bpmem. Code for handling
efb2ram updates was added to TextureCache.
There was a bug for preloaded RGBA8 textures, it only copied
half the texture. The TODO was wrong too.

|
Store the base hash for paletted textures in the texture cache entries
|
|
General: Replace GC_ALIGN macros with alignas
|
|
|
|
This checks every TEXTURE_KILL_THRESHOLD frames, to see if the hash for the memory area of the efb copy has hanged. If it has changed, the efb copy can be removed, it wouldn't be used anymore. Before this pr, some efb copies would never be deleted.
Fixes issue https://bugs.dolphin-emu.org/issues/6101 and possibly some other VRAM leaks.

|
|
Standard supported alignment -> out with compiler-specific.
|
|
|
|
Instead of having special case code for efb2tex that ignores hashes,
the only diffence between efb2tex and efb2ram now is that efb2tex
writes zeros to the memory instead of actual texture data.
Though keep in mind, all efb2tex copies will have hashes of zero as
their hash.
|

|
|
Addded a few duplicated depth copy texture formats to the enum
in TextureDecoder.h. These texture formats were already implemented
in TextureCacheBase and the ogl/dx11 texture cache implementations.
