Hi, this is a patchset to add the support for HDMI/DP audio notification via drm_audio_component framework on radeon and nouveau drivers. The notification mechanism works for long time on i915, and now AMDGPU patch is floating around. This fills the rest gap, the support for remaining radeon and nouveau drivers. The implementation is rather simple, and it just adds the hook for notification and ELD retrieval. The patch for radeon is basically a respin of my previous RFC patch. The counterpart change in HD-audio side has been already merged in sound.git tree for 5.4 kernel. The persistent branch, topic/hda-acomp-base, is provided there, so that you can pull into yours freely: git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git topic/hda-acomp-base This patchset itself is almost harmless without the HD-audio side changes (IOW, it doesn't help anything else, either :) thanks, Takashi === Takashi Iwai (2): drm/radeon: Add HD-audio component notifier support drm/nouveau: Add HD-audio component notifier support drivers/gpu/drm/Kconfig | 1 + drivers/gpu/drm/nouveau/Kconfig | 1 + drivers/gpu/drm/nouveau/dispnv50/disp.c | 111 ++++++++++++++++++++++++++++++++ drivers/gpu/drm/nouveau/nouveau_drv.h | 7 ++ drivers/gpu/drm/radeon/radeon.h | 3 + drivers/gpu/drm/radeon/radeon_audio.c | 92 ++++++++++++++++++++++++++ 6 files changed, 215 insertions(+) -- 2.16.4 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
