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

2011-10-16T21:14:54+00:00

commit cb7cf41961fe10773c491c75ae73539ad4bbed66 upstream.

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: retry aux transactions if there are status flags

2011-10-16T21:14:54+00:00

commit 4f332844cc87c5f99c5300f788abbe8a8c731390 upstream.

If there are error flags in the aux status, retry the transaction.
This makes aux much more reliable, especially on llano systems.

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

2011-10-16T21:14:52+00:00

commit 12d5180bd7e683a4ae80830b82ba67e7b7fac7b2 upstream.

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.

v2: drop now unused channel_remap functions.

drm/radeon/kms: add retry limits for native DP aux defer

2011-10-16T21:14:52+00:00

commit 6375bda073724ead7df08746866b724b1799a295 upstream.

The previous code could potentially loop forever.  Limit
the number of DP aux defer retries to 4 for native aux
transactions, same as i2c over aux transactions.

drm/radeon/kms: fix regression in DP aux defer handling

2011-10-16T21:14:52+00:00

commit 109bc10d30f33e84f1d7289f0039e0c858ade82f upstream.

An incorrect ordering in the error checking code lead
to DP aux defer being skipped in the aux native write
path.  Move the bytes transferred check (ret == 0)
below the defer check.

commit 5ba7ddf81634bfdf32d09261d2959e3f5b7c4263 upstream.

Only disable the pipe if the monitor is physically
disconnected.  The previous logic also disabled the
pipe if the link was trained.

drm/radeon/kms: fix DDIA enable on some rs690 systems

2011-10-03T18:41:03+00:00

commit fdfc61594e6de21c23f955818ef78bcab9bafe40 upstream.

DVOOutputControl checks the value of of bios scratch reg 3
on some tables and assumes the encoder is already enabled
if the DFP2_ACTIVE bit is set.  Clear that bit so the table
sets the DDIA enable bit properly.

drm/radeon/kms: Make GPU/CPU page size handling consistent in blit code (v2)

2011-10-03T18:40:33+00:00

commit 003cefe0c238e683a29d2207dba945b508cd45b7 upstream.

The BO blit code inconsistenly handled the page size.  This wasn't
an issue on system with 4k pages since the GPU's page size is 4k as
well.  Switch the driver blit callbacks to take num pages in GPU
page units.

Fixes lemote mipsel systems using AMD rs780/rs880 chipsets.

v2: incorporate suggestions from Michel.
