drm/amdgpu: Handle null atom context in VBIOS info ioctl

2023-10-06T11:18:16+00:00

[ Upstream commit 5e7e82254270c8cf8b107451c5de01cee2f135ae ] On some APU systems, there is no atom context and so the atom_context struct is null. Add a check to the VBIOS_INFO branch of amdgpu_info_ioctl to handle this case, returning all zeroes.

drm/amdgpu: disable runpm if we are the primary adapter

2022-01-11T14:35:17+00:00

commit b95dc06af3e683d6b7ddbbae178b2b2a21ee8b2b upstream. If we are the primary adapter (i.e., the one used by the firwmare framebuffer), disable runtime pm. This fixes a regression caused by commit 55285e21f045 which results in the displays waking up shortly after they go to sleep due to the device coming out of runtime suspend and sending a hotplug uevent. v2: squash in reworked fix from Evan Fixes: 55285e21f045 ("fbdev/efifb: Release PCI device's runtime PM ref during FB destroy") Bug: https://bugzilla.kernel.org/show_bug.cgi?id=215203 Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1840 Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman
