Exports a DMA buf fd of a given KFD buffer handle. This is intended for being able to import KFD BOs into GEM contexts to leverage the amdgpu_bo_va API for more flexible virtual address mappings. It will also be used for the new upstreamable RDMA solution coming to UCX and RCCL. The corresponding user mode change (Thunk API and kfdtest) is here: https://github.com/fxkamd/ROCT-Thunk-Interface/commits/fxkamd/dmabufSigned-off-by:

This will let us pass the kms_hdr.bpc_switch IGT test. The reason the bpc restriction was required is historical. At one point in time we were not falling back to a lower bpc when we didn't have enough bandwidth for the maximum bpc reported by a display. This meant that we couldn't enable some high refresh modes unless we limitted the bpc. Starting with this patch the issue is fixed: commit cbd14ae7 ("drm/amd/display: Fix incorrectly pruned modes with deep color") This patch implemented a fallback mechanism if mode validation failed at the max bpc. This means users now automatically get all modes that can be supported by at least 6 bpc. The driver will enable the mode with the highest possible bpc that is supported by the display. v2: - explain why this is no longer needed (Michel) - refer to commit that fixed bpc fallback (Michel) Signed-off-by:

Apple iMac11,2 (mid 2010) also with Radeon HD-4670 that has the same issue as iMac10,1 (late 2009) where the internal eDP panel stays dark on driver load. This patch treats iMac11,2 the same as iMac10,1, so the eDP panel stays active. Additional steps: Kernel boot parameter radeon.nomodeset=0 required to keep the eDP panel active.

The parent for the backlight device should be the drm-connector object, not the PCI device. Userspace relies on this to be able to detect which backlight class device to use on hybrid gfx devices where there may be multiple native (raw) backlight devices registered. Specifically gnome-settings-daemon expects the parent device to have an "enabled" sysfs attribute (as drm_connector devices do) and tests that this returns "enabled" when read. This aligns the parent of the backlight device with i915, nouveau, radeon. Note that drivers/gpu/drm/amd/amdgpu/atombios_encoders.c also already uses the drm_connector as parent, only amdgpu_dm.c used the PCI device as parent before this change. Note this is marked as a RFC because I don't have hw to test, so this has only been compile tested! If someone can test this on actual hw which hits the changed code path that would be great.
