* 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
This lowers the relative cost of this function from ~2.25% to ~1.80% on
gcc 9 which I found quite surprising, some of it probably gets inlined
better in the callers, but I haven’t been able to isolate which parts.
Clear() error checking simplified a bit
Mount() now clears cache if ID was changed from last or NULL specified.
Implemented vfs::host::remove_all():
Clear() now uses vfs::host::remove_all() to match behaviour on Windows with ps3
* Ignore more warnings
These are intentional
* Signed/unsigned mismatch when comparing
* Explictly cast values
* Intentionally discard a nodiscard value
* Change ppu_tid to u32
* Do not use POSIX function name on Windows
* Qt: Use horizontalAdvance instead of width
* Change progress variables to u32
