We want programs besides the compositor to be able to enable or disable
panel power saving features. However, since they are currently only

On GFX 9.4.3, for a given KFD node, fetch the correct drm device from

This is to work around a bug in function drm_prime_pages_to_sg if length
of nr_pages >= 4GB, by doing the same check for max_segment and then
calling sg_alloc_table_from_pages_segment directly instead.
This issue shows up on APU because VRAM is allocated as GTT memory. It

Some manufacturers have intentionally put an EDID that differs from

The ACPI specification allows for an EDID to be up to 512 bytes but
the _DDC EDID fetching code will only try up to 256 bytes.
Modify the code to instead start at 512 bytes and work it's way
down instead.

Some laptops ship an EDID in the BIOS encoded in the _DDC method that

This is the EDID that is used by the AMD Windows driver, and so sometimes
different results are found in different operating systems.

Hi guys,
those two patches clean up gang submit. The first one should prevent
crashes when gang submit is used together with a reserved VMID.
The second rejects gang submits with a reserved VMID when this won't
work because of HW limitations.
