2012-11-01DRM/radeon: For single CRTC GPUs move handling of CRTC_CRT_ON to crtc_dpms().Egbert Eich
On all dual CRTC GPUs the CRTC_CRT_ON in the RADEON_CRTC_EXT_CNTL register controls the CRTC of the primary DAC. Therefore it is set in the DAC DMPS function. This is different for GPU's with a single CRTC but a primary and a TV DAC: here it controls the single CRTC no matter where it is routed. Therefore we set it here. This avoids an elaborate on/off state tracking since both primary_dac_dpms() and tv_dac_dpms() functions would have to touch this bit. On single CRTC GPUs with just one DAC it's irrelevant where this bit is handled. agd5f: fix warning Signed-off-by: Egbert Eich <eich@suse.de> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2012-11-01DRM/Radeon: On DVI-I use Load Detection when EDID is bogus.Egbert Eich
The Radeon driver uses the analog/digital flag to determine if the DAC or the TMDS encoder should be enabled on a DVI-I connector. If the EDID is bogus this flag is no longer reliable. This fix adds a fallback to DAC load detection to determine if anything is connected to the DAC. If not and a (bogus) EDID is found it assumes a digital display is connected. This works around problems with some crappy IPMI devices using Radeon ES1000. Signed-off-by: Egbert Eich <eich@suse.de> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2012-11-01DRM/Radeon: Fix primary DAC Load Detection for RV100 chips.Egbert Eich
For Radeon 7500 ATI recommends a DAC_FORCE value of 0x1ac. This value works better on ES1000 (RV100) chips, too, as it doesn't produce any false positives on any cards I have tested. Therefore let's assume that this value is good for all RV100 and RV200 chipset generations. Signed-off-by: Egbert Eich <eich@suse.de> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2012-10-23drm/ttm: Fix a theoretical race in ttm_bo_cleanup_refs()Thomas Hellstrom
In theory, that function could release the lru lock between checking for bo on ddestroy list and a successful reserve if the bo was already reserved, and the function was called with waiting reserves allowed. However, all current reservers of a bo on the ddestroy list would atomically take the bo off the list after a successful reserve so this race should not have been hit, so no need to backport for stable. This patch also fixes a case found by Maarten Lankhorst where ttm_mem_evict_first called with no_wait_gpu would incorrectly spin waiting for bo idle if trying to evict a busy buffer that also sits on the ddestroy list.

So, from now on, this perliminary_hw_support module parameter shall be used by all upcoming platforms that are still under enabling.

2012-10-16Revert "drm/i915: Try harder to complete DP training pattern 1"Daniel Vetter
This reverts commit 2477367083b3eaa97f87993ab26627a02f350551. If (for whatever reason) the DP sink device never asks for the maximal voltage level, we never don't hit the check that should bail us out after 5 retries of the same voltage. Which leads to an endless loop in the DP link training code, which hangs the driver. Now some more DP link training experiments on eDP panels seem to indicate that our training algorithm isn't robust enough anyway and needs more work. Hence for 3.7-fixes, let's just revert the regressing commit instead of trying to apply more duct-tape.
