drm/amdgpu: skip to program GFXDEC registers for suspend abort

2024-03-01T12:34:56+00:00

[ Upstream commit 93bafa32a6918154aa0caf9f66679a32c2431357 ]

In the suspend abort cases, the gfx power rail doesn't turn off so
some GFXDEC registers/CSB can't reset to default value and at this
moment reinitialize GFXDEC/CSB will result in an unexpected error.
So let skip those program sequence for the suspend abort case.

drm/amd: Enable PCIe PME from D3

2024-01-25T23:35:45+00:00

commit bd1f6a31e7762ebc99b97f3eda5e5ea3708fa792 upstream.

When dGPU is put into BOCO it may be in D3cold but still able send
PME on display hotplug event. For this to work it must be enabled
as wake source from D3.

When runpm is enabled use pci_wake_from_d3() to mark wakeup as
enabled by default.

drm/amdgpu: expand runpm parameter

2023-08-15T22:08:29+00:00

Allow the user to specify -2 as auto enabled with displays.

By default we don't enter runtime suspend when there are
displays attached because it does not work well in some
desktop environments due to the driver sending hotplug
events on resume in case any new displays were attached
while the GPU was powered down.  Some users still want
this functionality though, so this lets you enable it.

[Why&How]
Freesync Video mode was enabled by default. Hence no need for the module

	The switch to drm eu helpers in 8a206685d36f ("drm/amdgpu: use
	drm_exec for GEM and CSA handling v2") clashed with the
	cosmetic cleanups from 30953c4d000b ("drm/amdgpu: Fix style
	issues in amdgpu_gem.c"). I
	kept the former since the cleanup up code is gone.
- drivers/gpu/drm/amd/amdgpu/atom.c.
	adf64e214280 ("drm/amd: Avoid reading the VBIOS part number
	twice") removed code that 992b8fe106ab ("drm/radeon: Replace
