2013-12-08drm/radeon/audio: correct ACR tablePierre Ossman
commit 3e71985f2439d8c4090dc2820e497e6f3d72dcff upstream. The values were taken from the HDMI spec, but they assumed exact x/1.001 clocks. Since we round the clocks, we also need to calculate different N and CTS values. Note that the N for 25.2/1.001 MHz at 44.1 kHz audio is out of spec. Hopefully this mode is rarely used and/or HDMI sinks tolerate overly large values of N. bug: https://bugs.freedesktop.org/show_bug.cgi?id=69675 Signed-off-by: Pierre Ossman <pierre@ossman.eu> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: Josh Boyer <jwboyer@fedoraproject.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Commit 99d79aa2f3b7729e7290e8bda5d0dd8b0240ec62 (backported by b2a9484006875ecd7d94582e7bcb72a02682be92) was supposed to fix rv6xx_asic struct. In kernel 3.10 we didn't have that struct yet, so the original patch should never be backported to the 3.10. Accidentally it has applied and modified different struct (r520_asic) that shouldn't have any HDMI callbacks at all.

2013-10-01drm/radeon/atom: workaround vbios bug in transmitter table on rs880 (v2)Alex Deucher
commit 91f3a6aaf280294b07c05dfe606e6c27b7ba3c72 upstream. The OUTPUT_ENABLE action jumps past the point in the coder where the data_offset is set on certain rs780 cards. This worked previously because the OUTPUT_ENABLE action is always called immediately after the ENABLE action so the data_offset remained set. In 6f8bbaf568c7f2c497558bfd04654c0b9841ad57 (drm/radeon/atom: initialize more atom interpretor elements to 0), we explictly reset data_offset to 0 between atom calls which then caused this to fail. The fix is to just skip calling the OUTPUT_ENABLE action on the problematic chipsets. The ENABLE action does the same thing and more. Ultimately, we could probably drop the OUTPUT_ENABLE action all together on DCE3 asics. fixes: https://bugzilla.kernel.org/show_bug.cgi?id=60791 v2: only rs880 seems to be affected Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2013-08-14drm/radeon: select audio dto based on encoder id for DCE3Alex Deucher
commit e1accbf0543eecfdb161131208c3dfefee22d61f upstream. 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@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit 9cc2e0e9f13315559c85c9f99f141e420967c955 upstream. Changing the UVD BOs offset on suspend/resume doesn't work because the VCPU internally keeps pointers to it. Just keep it always pinned and save the content manually.

commit aeea40cbf9388fc829e66fa049f64d97fd72e118 upstream. They still seem to cause instability on some r6xx parts. As a follow up, we can switch to using CP DMA for bo moves on r6xx as a lighter weight alternative to using the 3D engine. A version of this patch should also go to stable kernels.

2013-08-04radeon kms: do not flush uninitialized hotplug workSergey Senozhatsky
commit a01c34f72e7cd2624570818f579b5ab464f93de2 upstream. Fix a warning from lockdep caused by calling flush_work() for uninitialized hotplug work. Initialize hotplug_work, audio_work and reset_work upon successful radeon_irq_kms_init() completion and thus perform hotplug flush_work only when rdev->irq.installed is true.

The ProcessAuxChannel table on some rv635 boards assumes the divmul members are initialized to 0 otherwise we get an invalid fb offset since it has a bad mask set when setting the fb base.

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.
