drm/edid: don't return stack garbage from supports_rb

2012-06-21T08:34:13+00:00

We need to initialize this to false, because the is_rb callback only
ever sets it to true.

Noticed while reading through the code.

Merge branch 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel into drm-fixes

2012-06-16T13:45:17+00:00

* 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel:
  drm/i915: cache the EDID for eDP panels
  Revert "drm/i915/dp: Use auxch precharge value of 5 everywhere"
  drm/i915: eDP aux needs vdd
  drm/i915: don't enumerate HDMID if an eDP panel is already active on the port

drm/i915: cache the EDID for eDP panels

2012-06-16T13:39:02+00:00

They aren't going anywhere, and probing on DDC can cause the panel to
blank briefly, so read them up front and cache them for later queries.

v2: fix potential NULL derefs in intel_dp_get_edid_modes and
    intel_dp_get_edid (Jani)
    copy full EDID length, including extension blocks (Takashi)
    free EDID on teardown (Takashi)
v3: malloc a new EDID buffer that's big enough for the memcpy (Chris)
v4: change handling of NULL EDIDs, just preserve the NULL behavior
    across detects and mode list fetches rather than trying to re-fetch
    the EDID (Chris)
v5: be glad that Chris is around to remind me to hit C-x C-s before
    committing.

Revert "drm/i915/dp: Use auxch precharge value of 5 everywhere"

2012-06-16T13:39:02+00:00

This reverts commit 092945e11c5b84f66dd08f0b87fb729715d377bc.

This commit prevents a DP screen from properly training the link.
Oddly enough it works, once the machine has been warm-booted with an
older kernel.

According to DP docs this _should_ have been the right precharge time.
Also, the commit that originally introduces this was just general snb
DP enabling and didn't mention any specific reason for this special
value. Whatever, trust the reporter that this makes things worse and
let's just revert it.

v2: Less spelling fail.

v2: Do the eDP vdd dance of simply not probing the OUI on eDP panels
as suggested by Chris Wilson.

drm/i915: don't enumerate HDMID if an eDP panel is already active on the port

2012-06-16T13:39:01+00:00

This prevents the HDMI detect functions from poking at an eDP
connected panel, which can lead to trouble.

[danvet: Note that we have some other reports of DP vs. HDMI fighting,
but the general case is a much bigger fish to fry.]
