2013-05-11drm/i915: Add no-lvds quirk for Fujitsu Esprimo Q900Christian Lamparter
commit 9e9dd0e889c76c786e8f2e164c825c3c06dea30c upstream. The "Mobile Sandy Bridge CPUs" in the Fujitsu Esprimo Q900 mini desktop PCs are probably misleading the LVDS detection code in intel_lvds_supported. Nothing is connected to the LVDS ports in these systems.

2013-01-17Revert "drm/i915: no lvds quirk for Zotac ZDBOX SD ID12/ID13"Daniel Vetter
commit 48e858340dae43189a4e55647f6eac736766f828 upstream. This reverts commit 9756fe38d10b2bf90c81dc4d2f17d5632e135364. The bogus lvds output is actually a lvds->hdmi bridge, which we don't really support. But unconditionally disabling it breaks some existing setups.

2012-12-10i915: Quirk no_lvds on Gigabyte GA-D525TUD ITX motherboardCalvin Walton
commit a51d4ed01e5bb39d2cf36a12f9976ab08872c192 upstream. This board is incorrectly detected as having an LVDS connector, resulting in the VGA output (the only available output on the board) showing the console only in the top-left 1024x768 pixels, and an extra LVDS connector appearing in X. It's a desktop Mini-ITX board using an Atom D525 CPU with an NM10 chipset. I've had this board for about a year, but this is the first time I noticed the issue because I've been running it headless for most of its life.

2011-05-09drm/i915/lvds: Only act on lid notify when the device is onAlex Williamson
If we're using vga switcheroo, the device may be turned off and poking it can return random state. This provokes an OOPS fixed separately by 8ff887c847 (drm/i915/dp: Be paranoid in case we disable a DP before it is attached).

2011-04-05drm/i915/lvds: Remove 0xa0 DDC probe for LVDSChris Wilson
This is a revert of 428d2e828c0a68206e5158a42451487601dc9194. This is broken in the same manner as for VGA: trying to write to an invalid address on the (currently 7-bit) i2c bus. One notable failure appears to be for MacBooks. The scary part was that it gave the appearance of working (i.e. reporting the absence of the panel) on various all-in-one machines with ghost LVDS panels and not failing for laptops.

2011-03-24drm/i915/lvds: Always return connected in the absence of better informationChris Wilson
The LVDS connector should default to connected. We tried our best to verify the claims of the BIOS that the hardware exists during init(), and then during detect() we then try to verify that the panel is open. In the event of an unsuccessful query, we should then always report that the LVDS panel is connected. This was only the case for gen2/3, later generations leaked the return value from the panel probe instead.

Linus Torvalds pointed out that our code was unbalanced when powering on the panel with respect to the power off sequence in that we were failing to restore the panel-fitter. The consequence of this would be that across a simple DPMS off/on for a non-native mode, without an intervening modeset, the panel fitter would remain disabled and the output would shift on the panel.

2010-09-18drm/i915: use GMBUS to manage i2c linksChris Wilson
Use the GMBUS interface rather than direct bit banging to grab the EDID over DDC (and for other forms of auxiliary communication with external display controllers). The hope is that this method will be much faster and more reliable than bit banging for fetching EDIDs from buggy monitors or through switches, though we still preserve the bit banging as a fallback in case GMBUS fails.

Commit 77d07fd9d73ef28689737c0952dbd5d6a5017743 introduced a regression where by not waiting for the panel to be turned off, left the panel and PLL registers locked across the modeset. Thus the panel remaining blank. As pointed out by Daniel Vetter, when testing LVDS it helps to open the laptop and look at the actual panel you are purporting to test. A second issue with the patch was that in order to modify the panel fitter before gen5, the pipe and the panel must have be completely powered down. So we wait.
