I read through them, and they're removed on the component device nodes stuff. That looks somewhat fishy from a lifetime point of view, and I think removing all that code would be better, too. > - qxl because it's debugfs files list is part of struct qxl_device which > is freed on unload before drm_minor_unregister() is called cleaning debugfs. In -next qxl is already demidlayered and there's no longer an unload hook.

Well this is definitely a massive step into a good direction, great work. For msm I think we can just move the two calls left in msm_debugfs_cleanup in msm_drm_uninit, right after the call to drm_dev_unregister. -Daniel > > > Note: > The driver patches are only compile tested. > > > Noralf. > > > Noralf Trønnes (19): > drm: debugfs: Remove all files automatically on cleanup > drm: drm_minor_register(): Clean up debugfs on failure > drm/atomic: Remove drm_atomic_debugfs_cleanup() > drm/amd/amdgpu: Remove drm_debugfs_remove_files() call > drm/armada: Remove armada_drm_debugfs_cleanup() > drm/etnaviv: allow build with COMPILE_TEST > drm/etnaviv: Remove etnaviv_debugfs_cleanup() > drm/hdlcd: Remove hdlcd_debugfs_cleanup() > drm/msm: Remove drm_debugfs_remove_files() calls > drm/nouveau: Remove nouveau_drm_debugfs_cleanup() > drm/omap: Remove omap_debugfs_cleanup() > drm/radeon: Remove drm_debugfs_remove_files() call > drm/sti: Remove drm_debugfs_remove_files() calls > drm/tegra: Remove tegra_debugfs_cleanup() > drm/tilcdc: Remove tilcdc_debugfs_cleanup() > drm/vc4: Remove vc4_debugfs_cleanup() > drm/virtio: Remove virtio_gpu_debugfs_takedown() > drm/qxl: Remove qxl_debugfs_takedown() > drm/i915: Remove i915_debugfs_unregister() > > drivers/gpu/drm/amd/amdgpu/amdgpu.h | 1 - > drivers/gpu/drm/amd/amdgpu/amdgpu_device.c | 20 ------ > drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 1 - > drivers/gpu/drm/arm/hdlcd_drv.c | 7 --- > drivers/gpu/drm/armada/armada_debugfs.c | 65 +++----------------- > drivers/gpu/drm/armada/armada_drm.h | 1 - > drivers/gpu/drm/armada/armada_drv.c | 3 - > drivers/gpu/drm/drm_atomic.c | 7 --- > drivers/gpu/drm/drm_crtc_internal.h | 1 - > drivers/gpu/drm/drm_debugfs.c | 29 +++++---- > drivers/gpu/drm/drm_drv.c | 2 +- > drivers/gpu/drm/etnaviv/Kconfig | 2 +- > drivers/gpu/drm/etnaviv/etnaviv_drv.c | 7 --- > drivers/gpu/drm/i915/i915_debugfs.c | 97 ++++-------------------------- > drivers/gpu/drm/i915/i915_drv.c | 1 - > drivers/gpu/drm/i915/i915_drv.h | 2 - > drivers/gpu/drm/i915/intel_drv.h | 1 - > drivers/gpu/drm/i915/intel_pipe_crc.c | 68 ++++----------------- > drivers/gpu/drm/msm/mdp/mdp5/mdp5_kms.c | 7 --- > drivers/gpu/drm/msm/msm_debugfs.c | 2 - > drivers/gpu/drm/msm/msm_perf.c | 29 +-------- > drivers/gpu/drm/msm/msm_rd.c | 31 +--------- > drivers/gpu/drm/nouveau/nouveau_debugfs.c | 62 ++++--------------- > drivers/gpu/drm/nouveau/nouveau_debugfs.h | 6 -- > drivers/gpu/drm/nouveau/nouveau_drm.c | 1 - > drivers/gpu/drm/omapdrm/omap_debugfs.c | 9 --- > drivers/gpu/drm/omapdrm/omap_drv.c | 1 - > drivers/gpu/drm/omapdrm/omap_drv.h | 1 - > drivers/gpu/drm/qxl/qxl_debugfs.c | 9 --- > drivers/gpu/drm/qxl/qxl_drv.c | 1 - > drivers/gpu/drm/qxl/qxl_drv.h | 1 - > drivers/gpu/drm/radeon/radeon_device.c | 16 ----- > drivers/gpu/drm/sti/sti_drv.c | 48 ++------------- > drivers/gpu/drm/sti/sti_dvo.c | 10 --- > drivers/gpu/drm/sti/sti_hda.c | 11 ---- > drivers/gpu/drm/sti/sti_hdmi.c | 11 ---- > drivers/gpu/drm/sti/sti_tvout.c | 8 --- > drivers/gpu/drm/tegra/drm.c | 7 --- > drivers/gpu/drm/tilcdc/tilcdc_drv.c | 12 ---- > drivers/gpu/drm/tilcdc/tilcdc_drv.h | 2 - > drivers/gpu/drm/vc4/vc4_debugfs.c | 6 -- > drivers/gpu/drm/vc4/vc4_drv.c | 1 - > drivers/gpu/drm/vc4/vc4_drv.h | 1 - > drivers/gpu/drm/virtio/virtgpu_debugfs.c | 8 --- > drivers/gpu/drm/virtio/virtgpu_drv.c | 1 - > drivers/gpu/drm/virtio/virtgpu_drv.h | 1 - > 46 files changed, 76 insertions(+), 542 deletions(-) > > -- > 2.10.2 > > _______________________________________________ > dri-devel mailing list > dri-devel@xxxxxxxxxxxxxxxxxxxxx > https://lists.freedesktop.org/mailman/listinfo/dri-devel -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
