Hi Dave, Daniel, One small suspend/resume fix, and the rest is restoring the runtime pm behavior that changed for some people when efifb dropped its extra runtime pm reference. Unfortunately the issue has not been something we've been able to reproduce consistently. The patches here basically re-enable the previous behavior, but in the driver if the device is the one that was used by the firmware framebuffer. It is limited to the device used by firmware since I don't want to regress hybrid graphics laptops and other systems that have been working fine years. The first patch adds a helper to fbmem.c to determine if the adapter is the one used by firmware. This needs a more indepth analysis, but with the holidays and the late state of the 5.16 cycle, this seems like the best option. The following changes since commit ce9b333c73a5a8707f2f446a837a6ca743ddcffd: Merge branch 'drm-misc-fixes' of ssh://git.freedesktop.org/git/drm/drm-misc into drm-fixes (2021-12-31 11:40:29 +1000) are available in the Git repository at: https://gitlab.freedesktop.org/agd5f/linux.git tags/amd-drm-fixes-5.16-2021-12-31 for you to fetch changes up to b95dc06af3e683d6b7ddbbae178b2b2a21ee8b2b: drm/amdgpu: disable runpm if we are the primary adapter (2021-12-31 08:57:45 -0500) ---------------------------------------------------------------- amd-drm-fixes-5.16-2021-12-31: amdgpu: - Suspend/resume fix - Restore runtime pm behavior with efifb ---------------------------------------------------------------- Alex Deucher (2): fbdev: fbmem: add a helper to determine if an aperture is used by a fw fb drm/amdgpu: disable runpm if we are the primary adapter Evan Quan (1): drm/amd/pm: keep the BACO feature enabled for suspend drivers/gpu/drm/amd/amdgpu/amdgpu.h | 1 + drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 28 ++++++++++++++++++ drivers/gpu/drm/amd/amdgpu/amdgpu_kms.c | 6 ++++ drivers/gpu/drm/amd/pm/swsmu/amdgpu_smu.c | 8 +++++- drivers/video/fbdev/core/fbmem.c | 47 +++++++++++++++++++++++++++++++ include/linux/fb.h | 1 + 6 files changed, 90 insertions(+), 1 deletion(-)
