Hi, This is unlikely to have any performance benefit except for maybe Vega and Raven.
The goals of this series are: - Remove 4 user SGPRs by merging per-shader descriptor arrays. Shader buffers and constant buffers share one array. Samplers and images share the other one. - Only upload (or dump to L2) those descriptor slots that are used by shaders. For example, it no longer does 2KB uploads of sampler slots in most situations. - For GFX9, allocate only those descriptors slots in CE RAM that are likely to be used by apps. If some shader needs more, the driver will upload the bigger array directly instead of using CE. This will switch dynamically based on what the current shader needs. CE RAM on GFX9 is actually large enough to handle most apps, we just need to use it intelligently. Please review.
