9c16228359 ac/nir/tess: write TCS per-vertex outputs to memory as vec4 stores at the end
This improves write throughput for TCS outputs. It follows the same idea
as attribute stores in hw GS. The improvement is easily measurable with
a microbenchmark.

It also has the advantage that multiple output stores to the same address
don't result in multiple memory stores. Each output components gets only
one memory store at the end of the shader.

a59464b6e3 radv,radeonsi: precompute and pass TCS per-vertex output stride via a user SGPR
It's a stride of 1 output, which isn't 16. It's 16 * num_threads,
aligned to 256.

tcs_offchip_layout has 5 unused bits, so let's use them.

80236f2367 ac/nir/tess: add if/endif for HS threads in NIR instead of ACO/LLVM
This just removes the if/endif wrapping for LLVM, and hopefully the ACO

2. num_components could end up being 0, so we need to round up instead.

d8624e6a79 winsys/amdgpu: Add support for queue priority in Mesa
Some checks are pending
macOS-CI / macOS-CI (dri) (push) Waiting to run
macOS-CI / macOS-CI (xlib) (push) Waiting to run
This patch adds support for queue priority levels in Mesa's AMDGPU winsys layer.
The changes include:

1. Updated ac_drm_create_userqueue() to accept and pass through flags parameter
2. Modified amdgpu_userq_init() to use the flags when creating queues
3. Added flags field to amdgpu_userq struct to store priority settings
4. Updated header definitions to match kernel UAPI changes

This aligns with the kernel changes provided by Alex:

https://lists.freedesktop.org/archives/amd-gfx/2025-April/122786.html

v2: We only need 1 normal priority queue and 1 TMZ normal priority queue.(Marek Olšák)
v3: Simplified to only support normal priority queues
v4: use a local variable instead of being in struct amdgpu_userq.(Marek Olšák)
v5: rebase the latest main branch.

6d9e708642 ac/gpu_info: reduce the tess offchip ring size and compute it proportionately
.. to the CU count. We allocated too much.

This reduces the tess offchip ring size as follows (examples):
- GFX11-12:
  - Navi31, Navi33, and Navi48 get 75% decrease.
  - Navi32 gets 68.75% decrease.
  - Phoenix gets 81.25% decrease.
  - Phoenix2 gets 93.75% decrease.
- GFX10.3:
  - Navi21 and Navi22 get 37.5% decrease.
  - Navi23 and Navi24 get 50% decrease.
  - Rembrandt gets 62.5% decrease.
  - VanGogh gets 75% decrease.
  - Raphael gets 93.75% decrease.
- GFX8-9:
  - Vega10 gets 0% decrease.
  - Vega20 gets 49.6% decrease.
  - Raven gets 65.3% decrease.
  - Raven2 gets 93.7% decrease.
  - Stoney gets 81% decrease.

No difference in performance was measured.

9333c0a1ed ac/gpu_info: compute the tess factor ring size proportionately to the CU count
No change in the size on GPUs with 16 CUs per SE such as Navi31 and Navi48.
Navi21 and Navi32 get 25% increase. (20 CUs per SE)

APUs get a significant decrease. For example:
- Phoenix gets 25% decrease
- Vangogh gets 50% decrease
- Phoenix2 gets 75% decrease
- Raphael and Stoney get 87.5% decrease
