2011-10-03drm/radeon/kms: add retry limits for native DP aux deferAlex Deucher
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.

2011-10-03drm/radeon/kms: fix regression in DP aux defer handlingAlex Deucher
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.

2011-08-15drm/radeon/kms: don't try to be smart in the hpd handlerAlex Deucher
Attempting to try and turn off disconnected display hw in the hotput handler lead to more problems than it helped. For now just register an event and only attempt the do something interesting with DP. Other connectors are just too problematic: - Some systems have an HPD pin assigned to LVDS, but it's rarely if ever connected properly and we don't really care about hpd events on LVDS anyway since it's always connected. - The HPD pin is wired up correctly for eDP, but we don't really have to do anything since the events since it's always connected. - Some HPD pins fire more than once when you connect/disconnect - etc. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=39882 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com>
2011-07-26drm/radeon/kms: fix DP training for DPEncoderService revision bigger than 1.1Jerome Glisse
DPEncoderService newer than 1.1 can't properly program the DP (display port) link training. When facing such version use the DIGxEncoderControl method instead. Fix DP link training on some R7XX.

2011-05-20drm/radeon/kms: simplify hotplug handler logicAlex Deucher
In the hotplug handler, just use the drm dpms functions. If the monitor is plugged in, turn it on, if it's not, turn it off. This also reduces power usage by turning off the encoder and crtc when the monitor is unplugged. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2010-08-20drm/radeon/kms: rework encoder handlingAlex Deucher
On most newer asics, digital encoders have two links each and they can be used independantly. As such, treat them as separate encoders otherwise the individual links will not get programmed properly at modeset time.

2010-02-01drm/kms/radeon: pick digitial encoders smarter. (v3)Dave Airlie
booting a Lenovo W500 with LVDS + DP outputs showed up a TODO we had on our list, to pick a correct digital encoder block. The LVTMA encoder requires the second digital encoder, all others can use any encoder at all. This fixes the digital encoder selection logic to enable LVDS/DP combos to work okay. V2: fix silly addition of connector dig_block and cleanup the other places in the code that pick the encoder. V3: rename to dig_encoder and clean up further - also fix the picking algorithm. tested on Lenovo W500 + desktop 3650 cards. Signed-off-by: Dave Airlie <airlied@redhat.com>
