* Limit Custom Anisotropic Filtering to only fully mipmapped textures
There's a major flaw with the anisotropic filtering setting that causes @GamerzHell9137 to report graphical bugs that otherwise wouldn't be there, because he just won't set it to Auto. This should fix those issues, hopefully.
These bugs are generally because anisotropic filtering is enabled on something that it shouldn't be, such as a post process filter or some data texture. This PR maintains two host samplers when custom AF is enabled, and only uses the forced AF one when the texture is 2d and fully mipmapped (goes down to 1x1). This is because game textures are the ideal target for this filtering, and they are typically fully mipmapped, unlike things like screen render targets which usually have 1 or just a few levels.
This also only enables AF on mipmapped samplers where the filtering is bilinear or trilinear. This should be self explanatory.
This PR also allows the changing of Anisotropic Filtering at runtime, and you can immediately see the changes. All samplers are flushed from the cache if the setting changes, causing them to be recreated with the new custom AF value. This brings it in line with our resolution scale. 😌
* Expected minimum mip count for large textures rather than all, address feedback
* Use Target rather than Info.Target
* Retrigger build?
* Fix rebase
* Replace CacheResourceWrite with more general "precise" write
The goal of CacheResourceWrite was to notify GPU resources when they were modified directly, by looking up the modified address/size in a structure and calling a method on each resource. The downside of this is that each resource cache has to be queried individually, they all have to implement their own way to do this, and it can only signal to resources using the same PhysicalMemory instance.
This PR adds the ability to signal a write as "precise" on the tracking, which signals a special handler (if present) which can be used to avoid unnecessary flush actions, or maybe even more. For buffers, precise writes specifically do not flush, and instead punch a hole in the modified range list to indicate that the data on GPU has been replaced.
The downside is that precise actions must ignore the page protection bits and always signal - as they need to notify the target resource to ignore the sequence number optimization.
I had to reintroduce the sequence number increment after I2M, as removing it was causing issues in rabbids kingdom battle. However - all resources modified by I2M are notified directly to lower their sequence number, so the problem is likely that another unrelated resource is not being properly updated. Thankfully, doing this does not affect performance in the games I tested.
This should fix regressions from #2624. Test any games that were broken by that. (RF4, rabbids kingdom battle)
I've also added a sequence number increment to ThreedClass.IncrementSyncpoint, as it seems to fix buffer corruption in OpenGL homebrew. (this was a regression from removing sequence number increment from constant buffer update - another unrelated resource thing)
* Add tests.
* Add XML docs for GpuRegionHandle
* Skip UpdateProtection if only precise actions were called
This allows precise actions to skip reprotection costs.
* Make GPU memory manager a member of GPU channel
* Move physical memory instance to the memory manager, and the caches to the physical memory
* PR feedback
* Support separate textures and samplers
* Add missing bindless flag, fix SNORM format on buffer textures
* Add missing separation
* Add comments about the new handles
