2013-08-08drm/radeon: fix audio dto calculation on DCE3+ (v3)Alex Deucher1-2/+24
Need to set the wallclock ratio and adjust the phase and module registers appropriately. May fix problems with audio timing at certain display timings. v2: properly handle clocks below 24mhz v3: rebase r600 changes Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-07-30drm/radeon: fix audio dto programming on DCE4+Alex Deucher1-1/+1
We need to set the dto source before setting the dividers otherwise we may get stability problems with the dto leading to audio playback problems. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Cc: stable@vger.kernel.org
2013-07-14drm/radeon/hdmi: make sure we have an afmt block assignedAlex Deucher1-0/+6
Prevents a segfault if an afmt block is not assigned to the encoder such as in the LVDS or eDP case. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=66714 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
2013-06-12drm/radeon: fix AVI infoframe generationAlex Deucher1-9/+2
- remove adding 2 to checksum, this is incorrect. This was incorrectly introduced in: 92db7f6c860b8190571a9dc1fcbc16d003422fe8 http://lists.freedesktop.org/archives/dri-devel/2011-December/017717.html However, the off by 2 was due to adding the version twice. From the examples in the URL above: [Rafał Miłecki][RV620] fglrx: 0x7454: 00 A8 5E 79 R600_HDMI_VIDEOINFOFRAME_0 0x7458: 00 28 00 10 R600_HDMI_VIDEOINFOFRAME_1 0x745C: 00 48 00 28 R600_HDMI_VIDEOINFOFRAME_2 0x7460: 02 00 00 48 R600_HDMI_VIDEOINFOFRAME_3 =================== (0x82 + 0x2 + 0xD) + 0x1F8 = 0x289 -0x289 = 0x77 However, the payload sum is not 0x1f8, it's 0x1f6. 00 + A8 + 5E + 00 + 00 + 28 + 00 + 10 + 00 + 48 + 00 + 28 + 00 + 48 = 0x1f6 Bits 25:24 of HDMI_VIDEOINFOFRAME_3 are the packet version, not part of the payload. So the total would be: (0x82 + 0x2 + 0xD) + 0x1f6 = 0x287 -0x287 = 0x79 - properly emit the AVI infoframe version. This was not being emitted previous which is probably what caused the issue above. This should fix blank screen when HDMI audio is enabled on certain monitors. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org Cc: Rafał Miłecki <zajec5@gmail.com>
2013-05-20drm/radeon/dce2: use 10khz units for audio dto calculationAlex Deucher1-4/+3
Avoids overflows on DCE2.x devices. Also clarify the calculation on other asics. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
2013-04-24drm/radeon/evergreen: set SAD registersRafał Miłecki1-0/+63
This allows audio (alsa) driver to read them and have a clue about audio capabilities of connected receiver. This has been verified to be compatible with fglrx behaviour for Onkyo TX-SR605 and Denon 1912. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-04-24drm/radeon: switch audio handling to use callbacksAlex Deucher1-0/+17
