Second iteration of my endeavour to rid nouveau, radeon and amdgpu of runtime pm ref leaks. Patches 1 to 8 are identical to v1. Patch 9 of v1 modified the DRM core to turn off all CRTCs on driver unload. Based on feedback by Daniel Vetter, I've replaced this with a helper to turn off all CRTCs, which is called by nouveau, radeon and amdgpu on unload. In other words, this is now opt-in. So patch 9 of v1 is replaced with new patches 9 to 12. A by-product of patch 9 is a helper which turns off a *single* CRTC. This is open coded in three other places in the DRM tree and patches 13 to 15 refactor those to use the new helper. To ease reviewing, I've pushed this series to GitHub: https://github.com/l1k/linux/commits/drm_runpm_fixes_v2 The discussion on v1 is archived here: https://lists.freedesktop.org/archives/dri-devel/2016-May/thread.html#108278 Thanks, Lukas Lukas Wunner (15): drm/nouveau: Don't leak runtime pm ref on driver unload drm/nouveau: Forbid runtime pm on driver unload drm/radeon: Don't leak runtime pm ref on driver unload drm/radeon: Don't leak runtime pm ref on driver load drm/radeon: Forbid runtime pm on driver unload drm/amdgpu: Don't leak runtime pm ref on driver unload drm/amdgpu: Don't leak runtime pm ref on driver load drm/amdgpu: Forbid runtime pm on driver unload drm: Add helpers to turn off CRTCs drm/nouveau: Turn off CRTCs on driver unload drm/radeon: Turn off CRTCs on driver unload drm/amdgpu: Turn off CRTCs on driver unload drm: Use helper to turn off CRTC drm/i2c/ch7006: Use helper to turn off CRTC drm/nouveau/dispnv04: Use helper to turn off CRTC drivers/gpu/drm/amd/amdgpu/amdgpu_device.c | 1 + drivers/gpu/drm/amd/amdgpu/amdgpu_kms.c | 12 +++++-- drivers/gpu/drm/drm_crtc.c | 53 ++++++++++++++++++++++++++---- drivers/gpu/drm/i2c/ch7006_drv.c | 9 ++--- drivers/gpu/drm/nouveau/dispnv04/disp.c | 10 ------ drivers/gpu/drm/nouveau/dispnv04/tvnv17.c | 9 ++--- drivers/gpu/drm/nouveau/nouveau_display.c | 1 + drivers/gpu/drm/nouveau/nouveau_drm.c | 6 +++- drivers/gpu/drm/radeon/radeon_device.c | 4 +++ drivers/gpu/drm/radeon/radeon_display.c | 1 + drivers/gpu/drm/radeon/radeon_kms.c | 5 ++- include/drm/drm_crtc.h | 2 ++ 12 files changed, 77 insertions(+), 36 deletions(-) -- 2.8.1 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
