[Intel-gfx] [PATCH 1/2] drm/i915: Reject 90/270 degree rotated initial fbs

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We don't currently handle the initial fb readout correctly
for 90/270 degree rotated scanout. Reject it.

[Intel-gfx] [PATCH 2/2] drm/i915: Try to handle 90/270 degree rotated initial fb

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Do the fb size readout correctly for the 90/270 degree rotated
cases. Not sure if we're missing something else as well.

Also no idea whether the BIOS would ever do this.

Cross check with tiling-y to rule out garbage?

We could also check the stride is suitable for tiling. How much do you
trust that the registers light up a plane?

I guess we could do that. Hmm, and we should probably reject Yf because
it has no fence and so seems like it should not even be possible.

The hw stride is specified in tile units (hence the stride_mult).

Only skl+ have 90/270 rotation so i9xx_get_initial_plane_config() does
not require the check.
error: seems valid

And as evidenced by the next patch, plenty needs to be done to handle
90/270.
