2012-10-21drm/i915: use adjusted_mode instead of mode for checking the 6bpc force flagJani Nikula
commit 0c96c65b48fba3ffe9822a554cbc0cd610765cd5 upstream. The dithering introduced in commit 3b5c78a35cf7511c15e09a9b0ffab290a42d9bcf Author: Adam Jackson <ajax@redhat.com> Date: Tue Dec 13 15:41:00 2011 -0800 drm/i915/dp: Dither down to 6bpc if it makes the mode fit stores the INTEL_MODE_DP_FORCE_6BPC flag in the private_flags of the adjusted mode, while i9xx_crtc_mode_set() and ironlake_crtc_mode_set() use the original mode, without the flag, so it would never have any effect. However, the BPC was clamped by VBT settings, making things work by coincidence, until that part was removed in commit 4344b813f105a19f793f1fd93ad775b784648b95 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Fri Aug 10 11:10:20 2012 +0200 Use adjusted_mode instead of mode when checking for INTEL_MODE_DP_FORCE_6BPC to make the flag have effect. v2: Don't forget to fix this in i9xx_crtc_mode_set() also, pointed out by Daniel both before and after sending the first patch.

2012-10-21drm/radeon: Don't destroy I2C Bus Rec in radeon_ext_tmds_enc_destroy().Egbert Eich
commit 082918471139b07964967cfe5f70230909c82ae1 upstream. radeon_i2c_fini() walks thru the list of I2C bus recs rdev->i2c_bus[] to destroy each of them. radeon_ext_tmds_enc_destroy() however also has code to destroy it's associated I2C bus rec which has been obtained by radeon_i2c_lookup() and is therefore also in the i2c_bus[] list. This causes a double free resulting in a kernel panic when unloading the radeon driver.

commit c205b232a64fed6d26edd7e40985b396de99a27f upstream. Power gating is per crtc pair, but the powergating registers should be called individually. The hw handles power up/down properly. The pair is powered up if either crtc in the pair is powered up and the pair is not powered down until both crtcs in the pair are powered down. This simplifies programming and should save additional power as the previous code never actually power gated the crtc pair.

commit 81ee8fb6b52ec69eeed37fe7943446af1dccecc5 upstream. It seems we can not update the crtc scanout address. After disabling crtc, update to base address do not take effect after crtc being reenable leading to at least frame being scanout from the old crtc base address. Disabling crtc display request lead to same behavior. So after changing the vram address if we don't keep crtc disabled we will have the GPU trying to read some random system memory address with some iommu this will broke the crtc engine and will lead to broken display and iommu error message. So to avoid this, disable crtc. For flicker less boot we will need to avoid moving the vram start address.

2012-08-26drm/i915: reorder edp disabling to fix ivb MacBook AirDaniel Vetter
commit 35a38556d900b9cb5dfa2529c93944b847f8a8a4 upstream. eDP is tons of fun. It turns out that at least the new MacBook Air 5,1 model absolutely doesn't like the new force vdd dance we've introduced in commit 6cb49835da0426f69a2931bc2a0a8156344b0e41 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sun May 20 17:14:50 2012 +0200 drm/i915: enable vdd when switching off the eDP panel But that patch also tried to fix some neat edp sequence issue with the force_vdd timings. Closer inspection reveals that we've raised force_vdd only to do the aux channel communication dp_sink_dpms. If we move the edp_panel_off below that, we don't need any force_vdd for the disable sequence, which makes the Air happy. Unfortunately the reporter of the original bug that the above commit fixed is travelling, so we can't test whether this regresses things. But my theory is that since we don't check for any power-off -> force_vdd-on delays in edp_panel_vdd_on, this was the actual root-cause of this failure. With that force_vdd dance completely eliminated, I'm hopeful the original bug stays fixed, too. For reference the old bug, which hopefully doesn't get broken by this: https://bugzilla.kernel.org/show_bug.cgi?id=43163 In any case, regression fixers win over plain bugfixes, so this needs to go in asap. v2: The crucial pieces seems to be to clear the force_vdd flag uncoditionally, too, in edp_panel_off. Looks like this is left behind by the firmware somehow. v3: The Apple firmware seems to switch off the panel on it's own, hence we still need to keep force_vdd on, but properly clear it when switching the panel off.

2012-08-26drm/i915: ignore eDP bpc settings from vbtDaniel Vetter
commit 4344b813f105a19f793f1fd93ad775b784648b95 upstream. This has originally been introduced to not oversubscribe the dp links in commit 885a5fb5b120a5c7e0b3baad7b0feb5a89f76c18 Author: Zhenyu Wang <zhenyuw@linux.intel.com> Date: Tue Jan 12 05:38:31 2010 +0800 drm/i915: fix pixel color depth setting on eDP Since then we've fixed up the dp link bandwidth calculation code and should now automatically fall back to 6bpc dithering. So this is unnecessary. Furthermore it seems to break the new MacbookPro with retina display, hence let's just rip this out.

2012-08-26drm/i915: correctly order the ring init sequenceDaniel Vetter
commit 0d8957c8a90bbb5d34fab9a304459448a5131e06 upstream. We may only start to set up the new register values after having confirmed that the ring is truely off. Otherwise the hw might lose the newly written register values. This is caught later on in the init sequence, when we check whether the register writes have stuck.

2012-08-26drm/i915: prefer wide & slow to fast & narrow in DP configsJesse Barnes
commit 2514bc510d0c3aadcc5204056bb440fa36845147 upstream. High frequency link configurations have the potential to cause trouble with long and/or cheap cables, so prefer slow and wide configurations instead. This patch has the potential to cause trouble for eDP configurations that lie about available lanes, so if we run into that we can make it conditional on eDP.

2012-08-09nouveau: Fix alignment requirements on src and dst addressesMaarten Lankhorst
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.

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.

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.

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.
