drm/i915: Make g4x_fixup_plane() operational again
Don't enable the cursor until g4x_fixup_plane() had a chance to do
cast its magic spell.
Egbert writes:
"Today I had the chance to test this. First I tried
if I can still reproduce the blank with this patch
added when I disable my voodoo g4x_fixup_plane():
It turned out it still happens however very rarely
(like 1 out of 20 tries). When I reenabled my voodoo
the issue still occurred.
I had to switch two lines around, ie:
intel_enable_plane(dev_priv, plane, pipe);
if (IS_G4X(dev))
g4x_fixup_plane(dev_priv, pipe);
+ intel_crtc_update_cursor(crtc, true);
to avoid the blank screen issue - which is it didn't
happen in ~75 tries."
v2: Add a comment to remind people of the ordering constraints
