This allows us more reliable hotplug notification and ELD transfer without accessing HD-audio bus; it's more efficient, and more importantly, it works without waking up the runtime PM. The implementation is rather simplistic: radeon driver provides the get_eld ops for HD-audio, and it notifies the audio hotplug via pin_eld_notify callback upon each radeon_audio_enable() call. The pin->id is referred as the port number passed to the notifier callback, and the corresponding connector is looked through the encoder list in the get_eld callback in turn. The bind and unbind callbacks handle the device-link so that it assures the PM call order. Also, as a gratis bonus, this patch "fixes" the regression by the recent change in HD-audio to be more strict for the HDMI/DP connection, too. Since the HD-audio HDMI/DP codec requires both the connection bit and the valid ELD to be provided, it started failing on some RADEON gfx boards where the ELD update performed instably. As this change switches the communication to a direct way between the audio and the graphics drivers, now the system receives the proper ELD, and the HDMI/DP hotplug starts working again. [ v2: fix the logic in radeon_audio_component_get_eld to walk the connector list since that is where the EDID lives and we can derive the encoder from the connector because the encoder has not been assigned at this point (i.e., during monitor probe). v3: the component binding is moved outside radeon_audio_init() and _fini(), as those are called from suspend/resume, too. Drop modeset lock calls that caused Oops. Moved Kconfig change so that it can be applied on older kernels. v4: revive drm_modeset_lock*() again, add the missing device_link_remove() call at unbinding v5: squash in mutex fix v6: squash in fix for audio get_eld callback ] Link: https://gitlab.freedesktop.org/drm/amd/-/issues/1569 Signed-off-by: Takashi Iwai Signed-off-by: Alex Deucher --- drivers/gpu/drm/Kconfig | 1 + drivers/gpu/drm/radeon/radeon.h | 8 +++ drivers/gpu/drm/radeon/radeon_audio.c | 117 +++++++++++++++++++++++++++++++++ drivers/gpu/drm/radeon/radeon_device.c | 4 ++ 4 files changed, 130 insertions(+) (limited to 'drivers/gpu/drm/radeon') diff --git a/drivers/gpu/drm/Kconfig b/drivers/gpu/drm/Kconfig index 34f5a092c99e..fa986075e8fb 100644 --- a/drivers/gpu/drm/Kconfig +++ b/drivers/gpu/drm/Kconfig @@ -243,6 +243,7 @@ config DRM_RADEON select DRM_KMS_HELPER select DRM_TTM select DRM_TTM_HELPER + select SND_HDA_COMPONENT if SND_HDA_CORE select POWER_SUPPLY select HWMON select BACKLIGHT_CLASS_DEVICE diff --git a/drivers/gpu/drm/radeon/radeon.h b/drivers/gpu/drm/radeon/radeon.h index 166c18d62f6d..2e7161acd443 100644 --- a/drivers/gpu/drm/radeon/radeon.h +++ b/drivers/gpu/drm/radeon/radeon.h @@ -79,6 +79,7 @@ #include #include +#include #include "radeon_family.h" #include "radeon_mode.h" @@ -1796,6 +1797,9 @@ struct r600_audio { struct radeon_audio_funcs *hdmi_funcs;
