[PATCH vkd3d 01/41] vkd3d: Deal correctly with SM 5.1 register spaces.

Hans-Kristian Arntzen post at arntzen-software.no
Wed Jan 29 05:51:26 CST 2020


Resource index is found in idx[0] in SM 5.0, but idx[1] when using SM
5.1, and register space is encoded reparately. An rb_tree keeps track of
the internal resource index idx[0] and can map that to space/binding as
required when emitting SPIR-V.

For this to work, we must also make UAV counters register space aware.
In earlier implementation, UAV counter mask was assumed to correlate 1:1
with register_index, which breaks on SM 5.1.
