There are two audio dtos on radeon asics that you can select between. Normally, dto0 is used for hdmi and dto1 for DP, but it seems that the dto is somehow tied to the encoders on DCE3 asics. fixes: https://bugs.freedesktop.org/show_bug.cgi?id=67435 Signed-off-by: Alex Deucher <alexander.deucher@xxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/gpu/drm/radeon/r600_hdmi.c | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) --- a/drivers/gpu/drm/radeon/r600_hdmi.c +++ b/drivers/gpu/drm/radeon/r600_hdmi.c @@ -242,9 +242,15 @@ void r600_audio_set_dto(struct drm_encod /* according to the reg specs, this should DCE3.2 only, but in * practice it seems to cover DCE3.0 as well. */ - WREG32(DCCG_AUDIO_DTO0_PHASE, base_rate * 100); - WREG32(DCCG_AUDIO_DTO0_MODULE, clock * 100); - WREG32(DCCG_AUDIO_DTO_SELECT, 0); /* select DTO0 */ + if (dig->dig_encoder == 0) { + WREG32(DCCG_AUDIO_DTO0_PHASE, base_rate * 100); + WREG32(DCCG_AUDIO_DTO0_MODULE, clock * 100); + WREG32(DCCG_AUDIO_DTO_SELECT, 0); /* select DTO0 */ + } else { + WREG32(DCCG_AUDIO_DTO1_PHASE, base_rate * 100); + WREG32(DCCG_AUDIO_DTO1_MODULE, clock * 100); + WREG32(DCCG_AUDIO_DTO_SELECT, 1); /* select DTO1 */ + } } else { /* according to the reg specs, this should be DCE2.0 and DCE3.0 */ WREG32(AUDIO_DTO, AUDIO_DTO_PHASE(base_rate / 10) | Patches currently in stable-queue which might be from alexander.deucher@xxxxxxx are queue-3.10/drm-radeon-select-audio-dto-based-on-encoder-id-for-dce3.patch queue-3.10/drm-radeon-stop-sending-invalid-uvd-destroy-msg.patch -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
