drm: remove the EDID blob stored in the EDID property when it is disconnected

2010-04-26T14:47:45+00:00

commit 725398322d05486109375fbb85c3404108881e17 upstream.

Now the EDID property will be updated when the corresponding EDID can be
obtained from the external display device. But after the external device
is plugged-out, the EDID property is not updated. In such case we still
get the corresponding EDID property although it is already detected as
disconnected.

drm: Keep disabled outputs disabled after suspend / resume

2010-01-11T04:36:08+00:00

With the current DRM code, an output that has been powered off
from userspace will automatically power back on when resuming
from suspend. This patch fixes this behaviour.

Tested only with the Intel i915 driver on an Intel GM45 Express
chipset.

drm: disable all the possible outputs/crtcs before entering KMS mode

2009-12-09T03:28:07+00:00

Sometimes we will use a crtc for integerated LVDS, which is different with
that assigned by BIOS. If we want to get flicker-free transitions,
then we could read out the current state for it and set our current state
accordingly.

But it is true that if we aren't reading current state out, we do need
to turn everything off before modesetting.  Otherwise the clocks can get very
angry and we get things worse than a flicker at boot.
In fact we also do the similar thing in UMS mode. We will disable all the
possible outputs/crtcs for the first modesetting.

So we disable all the possible outputs/crtcs before entering the KMS mode.
Before we configure connector/encoder/crtc, the function of
drm_helper_disable_unused_function can disable all the possible outputs/crtcs.

If drivers don't init the fb helper on the connector, the cmdline
code won't work, but it shouldn't crash either.
