Currently, the driver code is flushing TLB on XCC 0 only.
Fix it by flushing on all XCCs within the partition.

Currently, we do not turn off retry faults in VM_CONTEXT_CNTL value
when passing it to MES if XNACK is off. This creates a situation where
XNACK is disabled in SQ but enabled in UTCL2, which is not recommended.
As a result, turn off/on retry faults in both SQ and UTCL2 when passing
vm_context_cntl value to MES if XNACK is disabled/enabled.

v4:
use func "amdgpu_gfx_get_hdp_flush_mask" to get ref_and_mask for
gfx9 through gfx12.
v3:
Unify the get_ref_and_mask function in amdgpu_gfx_funcs,
to support both GFX11 and earlier generations
v2:
place "get_ref_and_mask" in amdgpu_gfx_funcs instead of amdgpu_ring,
since this function only assigns the cp entry.
v1:
both gfx ring and mes ring use cp0 to flush hdp, cause conflict.
use function get_ref_and_mask to assign the cp entry.
reassign mes to use cp8 instead.

amdgpu_acpi_detect() calls some helper functions it calls have large
local structures. When the compiler inlines these helpers, their local
data adds to the amdgpu_acpi_detect() stack frame.
Mark the helpers with noinline_for_stack:
- amdgpu_atif_verify_interface()
- amdgpu_atif_get_notification_params()
- amdgpu_atif_query_backlight_caps()
- amdgpu_atcs_verify_interface()
- amdgpu_acpi_enumerate_xcc()
This keeps the large temporary objects inside the helper’s own stack
frame instead of being inlined into the caller, preventing the caller
from growing beyond the stack limit.
Fixes the below with gcc W=1:
drivers/gpu/drm/amd/amdgpu/amdgpu_acpi.c:1403:6: warning: stack frame size (1688) exceeds limit (1024) in 'amdgpu_acpi_detect' [-Wframe-larger-than]
