drm/amdgpu: Fix comparison in amdgpu_res_cpu_visible

2024-05-10T17:05:13+00:00

It incorrectly claimed a resource isn't CPU visible if it's located at
the very end of CPU visible VRAM.

drm/amdkfd: don't allow mapping the MMIO HDP page with large pages

2024-05-10T17:05:13+00:00

We don't get the right offset in that case.  The GPU has
an unused 4K area of the register BAR space into which you can
remap registers.  We remap the HDP flush registers into this
space to allow userspace (CPU or GPU) to flush the HDP when it
updates VRAM.  However, on systems with >4K pages, we end up
exposing PAGE_SIZE of MMIO space.

drm/xe: Use ordered WQ for G2H handler

2024-05-09T14:41:27+00:00

System work queues are shared, use a dedicated work queue for G2H
processing to avoid G2H processing getting block behind system tasks.

drm/xe/guc: Check error code when initializing the CT mutex

2024-05-09T14:40:59+00:00

The initialization via drmm_mutex_init can fail, so we need to check the
return code and escalate the failure.

The mutex initialization has been moved after all the other init steps
that can't fail, so we're always guaranteed to have those done and don't
have to check in the cleanup code.
