- Ensure incoming texture is large enough that the original one fits inside it to avoid back-and-forth succession.
- Make use of the resource manager to remove the obsolete textures to avoid holding on to the them which "leaks" VRAM.
The memory isn't leaking, it's just wasting space in temporary pool until renderer is closed.
- Partial stencil buffer clears were not implemented. This is for example where a game can choose to clear only some bits from the stencil buffer.
- Vulkan does not support masked stencil clears natively, it has to be implemented as a graphics operation.
- Also refactors vulkan overlay passes to use global resource system instead of forcing the render backend to own all of them and manage lifetimes.
- A few nagging issues remain, specifically that partial command stream
largely caused by poor synchronization structures for partial CS flush
and also the fact that occlusion map entries wait on a command buffer
and not an EID!
- Further improve aliased data preservation by unconditionally scanning.
Its is possible for cache aliasing to occur when doing memory split.
- Also sets up for RCB/RDB implementation
- Tagged eventIDs can be used to safely delete resources that are no
longer used
- TODO: Expand gc to collect images as well
- TODO: Fix the texture cache to avoid over-allocating image resources
- Ensures the current renderpass matches the image properties even when a cyclic reference is detected
- Solves SDK debug output error spam due to mismatching layouts and renderpasses
- Transition attachments to LAYOUT_GENERAL in case of a feedback loop
- Fixes appearance of garbage along polygon edges in some
post-processing passes.
- Also reverse this transition when rendering goes back to normal
- The fixed-point D24S8 format does special Z clamping during compare which matches PS3 behaviour
- D32S8 is a floating point format and comparison with Dref > 1 always fails causing black edges/borders
- Properly wait for the buffer transfer operation to finish before map/readback!
- Change vkFence to vkEvent which works more like a GL fence which is what is needed.
- Implement supporting methods and functions
- Do not destroy fence by immediately waiting after copying to dma buffer
- Properly synchronize when transitioning to/from GENERAL layout.
- General layout requires full pipeline dependency since its used in a 'general' sense. As such, its use is to be largely avoided.
- NVIDIA drivers hook into the msq before our nativeEvent handler. This means NV is aware of events before rpcs3 is aware of them and sometimes stops until a new event is triggered.
If rpcs3 is inside a driver call at this time, the system will deadlock since the driver waits for msq which waits for the renderer which waits for the driver.
- Use explicit hook management to control window events
- Add fence timeout to attempt detection of surface loss events
- Disable DEPTH<->RGBA typeless transfers for now as they require a lot more work to work for all vendors
- Do not allow switching layouts to UNDEFINED/PREINITIALIZED formats
- gl: Include an execution state wrapper to ensure state changes are consistent. Also removes a lot of required 'cleanup' for helper methods
- texture_cache: Make execition context a mandatory field as it is required for all operations. Also removes a lot of situations where duplicate argument is added in for both fixed and vararg fields
- Explicit read/write barrier for framebuffer resources depending on
usage. Allows for operations like optional memory initialization before
reading
