- This drastically improves memory allocation behavior.
Holding too many invalidated resources can lead to a cascading overallocation error as old resources hold refs to even older resources and nothing gets deleted.
- It's not worth it. We end up with a mish-mash of internal configuration parameters that don't match the surface.
Maybe with more abstraction it can work, but there is little benefit.
- Beware of clone operations. Blindly inheriting the parent's metadata is wrong.
- It is possible, especially when reusing a pre-existing slice, that the parent and child info has diverged
- For some reason this has a massive impact on performance above some arbitrary threshold of calls
Shows up under surface_cache::get_merged_memory_region when doing gathers.
- Replace old format-based detection with proper aspect test.
Explicit image aspect has been available for a long time, but older
code was not updated.
- Transfer writes are expected to clobber surface cache contents. Do NOT reload from CPU memory for writes.
- TODO: During transfer write to surface cache objects, lock memory if it was unlocked to avoid silly problems.
- Tracks which kind of raster was done (Z-ordered vs linear) throughout the application.
- This allows to identify if data is in the expected format or not.
- Do not allocate too many objects. This is a problem in games using dynamic memory allocators that can make it rare for a surface to fall on the same address twice, keeping zombie RTVs and DSVs alive much longer than needed.
- Current limit used is 256M of virtual VRAM which is impossible on retail PS3
- Avoid silly broken tests due to queue_tag being called before pitch is initialized.
- Return actual memory range covered and exclude trailing padding.
- Coordinates in src are to be calculated with src_pitch, not required_pitch.
- Implements render target data load (aka Read Color Buffer/Read Depth Buffer)
- Refactors vulkan surface barrier to be much cleaner.
- Removes redundant surface barrier invocations after doing a merged load
from surface cache.
- Adds explicit access modes when gathering surfaces from cache.
- Allows render targets to behave like stacked 3D views same as shader inputs are resolved
- Basically implements most of 'Read Color/Depth Buffers" option for 'free'.
- Allows splitting RTV/DSV resources if they are superceded by a partial surface
- Also allows intersecting new resources through the surface cache for proper inheritance from other scattered data
- TODO: Refactor bind_surface_as_rtt and bind_surface_as_ds to reduce asinine code duplication
