drm/radeon/kms/atom: fix handling of FB scratch indices

2011-10-19T08:47:47Z

FB scratch indices are dword indices, but we were treating them as byte indices. As such, we were getting the wrong FB scratch data for non-0 indices. Fix the indices and guard the indexing against indices larger than the scratch allocation. Fixes memory corruption on some boards if data was written past the end of the FB scratch array.

drm/radeon/kms/DCE4.1: fix Select_CrtcSource EncodeMode setting for DP bridges (v2)

2011-10-18T09:16:55Z

Settings in this table reflect the physical panel/connector rather than the internal dig encoding. v2: fix typo for DRM_MODE_CONNECTOR_VGA case. Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie

drm/radeon/kms/DCE4.1: ss is not supported on the internal pplls

2011-10-18T09:16:33Z

It's handled via external clock. It should already be protected by the external ss flag, but add an explicit check just in case. Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie

drm/radeon/kms/DCE4.1: fix dig encoder to transmitter mapping

2011-10-18T09:16:10Z

llano has fully routeable dig encoders similar to DCE3.2 while ontario has a hardcoded mapping similar to DCE4.0. Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie

drm/radeon/kms: use hardcoded dig encoder to transmitter mapping for DCE4.1

2011-10-06T10:45:30Z

The encoders are supposedly fully routeable, but changing the mapping doesn't always seem to take. Using a hardcoded mapping is much more reliable.

drm/radeon/kms: fix dp_detect handling for DP bridge chips

2011-10-05T09:31:40Z

The HPD pin is not reliable for detecting whether a monitor is connected or not. Skip HPD and just use DDC or load detection. Fixes phantom VGA connected bugs.

drm/radeon/kms: retry aux transactions if there are status flags

2011-10-05T09:30:50Z

If there are error flags in the aux status, retry the transaction. This makes aux much more reliable, especially on llano systems. Signed-off-by: Alex Deucher Reviewed-by: Michel Dänzer Cc: stable@kernel.org Signed-off-by: Dave Airlie

drm/radeon/kms: fix channel_remap setup (v2)

2011-10-04T16:24:14Z

Most asics just use the hw default value which requires no explicit programming. For those that need a different value, the vbios will program it properly. As such, there's no need to program these registers explicitly in the driver. Changing MC_SHARED_CHREMAP requires a reload of all data in vram otherwise its contents will be scambled. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=40103 v2: drop now unused channel_remap functions.

drm/radeon: Set cursor x/y to 0 when x/yorigin > 0.

2011-10-03T17:37:37Z

Apart from the obvious cleanup, this should make the line cursor_end = x - xorigin + w; correct now. Signed-off-by: Michel Dänzer Reviewed-by: Alex Deucher Signed-off-by: Dave Airlie
