nouveau: Fix alignment requirements on src and dst addresses

2012-08-09T15:23:12Z

commit ce806a30470bcd846d148bf39d46de3ad7748228 upstream. Linear copy works by adding the offset to the buffer address, which may end up not being 16-byte aligned. Some tests I've written for prime_pcopy show that the engine allows this correctly, so the restriction on lowest 4 bits of address can be lifted safely. The comments added were by envyas, I think because I used a newer version. Signed-off-by: Maarten Lankhorst Signed-off-by: Greg Kroah-Hartman

drm/nouveau: init vblank requests list

2012-08-09T15:23:11Z

commit 715855457e6bc93e148caf8cb3b5dcabbf605b0d upstream. Fixes kernel panic when vblank interrupt triggers before first sync to vblank request. (Besides init, remove some relevant leftovers from vblank rework) Reported-by: Ortwin Glück Signed-off-by: Marcin Slusarz Signed-off-by: Ben Skeggs Signed-off-by: Greg Kroah-Hartman

drm/radeon: fix dpms on/off on trinity/aruba v2

2012-08-09T15:23:11Z

commit fcedac670c3da0d17aaa5db1708694971e8024a9 upstream. The external encoder need to be setup again before enabling the transmiter. This seems to be only needed on some trinity/aruba to fix dpms on. v2: Add comment, only setup again on dce6 ie aruba or newer.

drm/radeon: on hotplug force link training to happen (v2)

2012-08-09T15:23:11Z

commit ca2ccde5e2f24a792caa4cca919fc5c6f65d1887 upstream. To have DP behave like VGA/DVI we need to retrain the link on hotplug. For this to happen we need to force link training to happen by setting connector dpms to off before asking it turning it on again. v2: agd5f - drop the dp_get_link_status() change in atombios_dp.c for now. We still need the dpms OFF change. Signed-off-by: Jerome Glisse Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

drm/radeon: fix hotplug of DP to DVI|HDMI passive adapters (v2)

2012-08-09T15:23:11Z

commit 266dcba541a1ef7e5d82d9e67c67fde2910636e8 upstream. No need to retrain the link for passive adapters. v2: agd5f - no passive DP to VGA adapters, update comments - assign radeon_connector_atom_dig after we are sure we have a digital connector as analog connectors have different private data. - get new sink type before checking for retrain. No need to check if it's no longer a DP connection. Signed-off-by: Jerome Glisse Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

drm/radeon: fix non revealent error message

2012-08-09T15:23:10Z

commit 8d1c702aa0b2c4b22b0742b72a1149d91690674b upstream. We want to print link status query failed only if it's an unexepected fail. If we query to see if we need link training it might be because there is nothing connected and thus link status query have the right to fail in that case. To avoid printing failure when it's expected, move the failure message to proper place. Signed-off-by: Jerome Glisse Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

drm/radeon: Try harder to avoid HW cursor ending on a multiple of 128 columns.

2012-08-09T15:23:10Z

commit f60ec4c7df043df81e62891ac45383d012afe0da upstream. This could previously fail if either of the enabled displays was using a horizontal resolution that is a multiple of 128, and only the leftmost column of the cursor was (supposed to be) visible at the right edge of that display. The solution is to move the cursor one pixel to the left in that case.

gma500,cdv: Fix the brightness base

2012-07-16T16:20:33Z

Some desktop environments carefully save and restore the brightness settings from the previous boot. Unfortunately they don't all check to see if the range has changed. The end result is that they restore a brightness of 100/lots not 100/100. As the old driver and the non-free GMA36xx driver both use 0-100 we thus need to go back doing the same thing to avoid users getting a mysterious black screen after boot.
