Hi,
I'm looking at the initialization sequences in gfxhub_v2_1.c. I'm
confused on whether the GCVM_CONTEXT1_CNTL CNTL reg can be written
before the corresponding GCVM_CONTEXT1_PAGE_TABLE_START_ADDR and
GCVM_CONTEXT1_PAGE_TABLE_END_ADDR reg is written.
Here is the background:

GFX PG is a pre-requisite for gfxoff IIRC. We shouldn't disable it on s2idle I
think.

In practice this should never happen. Applied with some minor coding

Function rv740_get_decoded_reference_divider() may return 0 due to
unpredictable reference divider value calculated in
radeon_atom_get_clock_dividers(). This will lead to
division-by-zero error once that value is used as a divider
in calculating 'clk_s'.
While unlikely, this issue should

Change the KFD_XCP_MEMORY_SIZE macro to return page align size, so KFD

application VRAM

Thanks for the fix. Please use move the +#ifdef CONFIG_ACPI_NUMA up a bit to
cover amdgpu_acpi_get_numa_size as well.

Looks it's better to add a Fixes tag like Fixes: 4dd9b5392c57 ("drm/amd/pm: fix
possible power mode mismatch between driver and PMFW"), if I understand it
correctly.

Check and pass the readonly flags when set amdgpu_ttm_tt flags
for readonly ptr pages. Otherwise, there is EPERM error returned
