Hi,
>> Based on your description, the above code should use "||" instead of "&&",
&& is to add more restriction here. To avoid skipping necessary TLB flush by
return.
For Asics < GFX11, !adev->gfx.is_poweron is always true (this paremeter is
intrudoced from GF
Since the script that collected the list of the expectation files was
bogus and placing test to the flakes list incorrectly, restart the
expectation files with the correct script.
This reduces a lot the number of tests in the flakes list.

Subject: [PATCH] drm/amdgpu:Check gfx poweron when skip flush_gpu_tlb
To fix the gpu recover
To fix the gpu recovery failed on GFX11 with gfxhub pagefault,
flush gpu tlb after reset on GFX11.
Gfxhub tlb flush need check if adev->gfx.is_poweron set.

SI hardware does not have doorbells at all, however currently the code
will try to do the allocation and thus fail, makes SI AMDGPU not usable.
Fix this failure by skipping doorbells allocation when doorbells count
is zero.
