drm/radeon/audio: correct ACR table

2013-12-08T15:29:17Z

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 Signed-off-by: Alex Deucher Cc: Josh Boyer Signed-off-by: Greg Kroah-Hartman

drm/radeon/audio: improve ACR calculation

2013-12-08T15:29:17Z

commit a2098250fbda149cfad9e626afe80abe3b21e574 upstream. In order to have any realistic chance of calculating proper ACR values, we need to be able to calculate both N and CTS, not just CTS. We still aim for the ideal N as specified in the HDMI spec though. bug: https://bugs.freedesktop.org/show_bug.cgi?id=69675 Signed-off-by: Pierre Ossman Signed-off-by: Alex Deucher Cc: Josh Boyer Signed-off-by: Greg Kroah-Hartman

drm/radeon/vm: don't attempt to update ptes if ib allocation fails

2013-12-04T19:06:29Z

commit 4cc948b94a222c310ae089c36718aac7a03aec90 upstream. If we fail to allocate an indirect buffer (ib) when updating the ptes, return an error instead of trying to use the ib. Avoids a null pointer dereference.

radeon: workaround pinning failure on low ram gpu

2013-12-04T19:05:53Z

commit 97b6ff6be9da7675aab339334fda996d6c5077d9 upstream. GPU with low amount of ram can fails at pinning new framebuffer before unpinning old one. On such failure, retry with unpinning old one before pinning new one allowing to work around the issue. This is somewhat ugly but only affect those old GPU we care about.

drm/radeon: adjust TN dpm parameters for stability (v2)

2013-12-04T19:05:52Z

commit 958b84fb3bef193198538b5c5902fa687cc8363f upstream. Adjust some of the TN dpm settings for stability. Enabling these features causes hangs and other stability problems on certain boards. v2: leave uvd dpm enabled Bug: https://bugzilla.kernel.org/show_bug.cgi?id=63101 Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman
