- Adhere to workgroup count limits as exposed by the GPU vendor.
They already execute properly even when going beyond the limits but this removes validation noise.
- Fix invocation counts for deswizzle kernel. The count was incorrect if blocksize was not 4, causing a bunch of useless work to be done.
- Handles all LODs per layer meaning cubemaps are now fully handled in 6 passes instead of 6 * (log2(width)) passes.
- Handles all LODs of a 3D texture in one pass as well.
- The improvements do warrant dropping down the number of allowed compute invocations a bit
- Remove use of uniform buffers for compute static data. Use push
constants instead.
- Minor touchups to the deswizzle code to avoid redundant data copies.
- Allow delaying report flushes triggered by image_in or buffer_notify
- When the report is ready, all the delayed transfers will automatically
be done.
- TODO: Make this configurable?
* rsx: Optimise primitive_restart::upload_untouched() with SSE4.1
This optimisation is only applied when skip_restart is false.
I’ve only tested the u16 codepath, as it is the one used in NieR.
In some very unscientific profiling, this function used to take 2.76% of
the total frame time at the save point of the port town, it now takes
about 0.40%.
* rsx: Mark all SSE4.1 functions with attributes on gcc and clang
This assures the compiler we will take care of only calling these
functions after having checked that the CPU does support these
instructions.
* rsx: Add an AVX2 implementation of primitive restart ibo upload
* rsx: Remove redefinition of SSE4.1 instructions
Now that clang is aware that our functions are compiled with SSE4.1, it
lets us generate this code using its intrinsics.
* rsx: Optimise vector to scalar conversion
This is done using minpos and srli intrinsics and generate less code
than before.
Thanks Nekotekina for the suggestion!
- Simplify active instance management. While multicontext support will
be required in future, this is better done with multiple logical devices
rather than multiple instances.
- Destroy the WSI surface on exit
- Enable depthBoundsTest explicitly. TODO: Properly check for supported
features.
subresource_layout::dim_in_texel
- These two are not always linked when working with compressed textures.
The actual texels extend past the actual size of the image if the size
is not aligned. e.g if height is 1, the real height is 4, but its not
possible to determine this from the aligned size. It could be 1, 2, 3 or
4 for example.
- Fixes image out-of-bounds writes when uploading from CPU
