drm/i915: Overcome display engine stride limits via GTT remapping
The display engine stride limits are getting in our way. On SKL+
we are limited to 8k pixels, which is easily exceeded with three
4k displays. To overcome this limitation we can remap the pages
in the GTT to provide the display engine with a view of memory
with a smaller stride.
The code is mostly already there as We already play tricks with
the plane surface address and x/y offsets.
A few caveats apply:
* linear buffers need the fb stride to be page aligned, as
otherwise the remapped lines wouldn't start at the same
spot
* compressed buffers can't be remapped due to the new
ccs hash mode causing the virtual address of the pages
to affect the interpretation of the compressed data. IIRC
the old hash was limited to the low 12 bits so if we were
using that mode we could remap. As it stands we just refuse
to remapp with compressed fbs.
* no remapping gen2/3 as we'd need a fence for the remapped
vma, which we currently don't have. Need to deal with the
fence POT requirements, and do something about the gen2
gtt page size vs tile size difference
v2: Rebase due to is_ccs_modifier()
Fix up the skl+ stride_mult mess
memset() the gtt_view because otherwise we could leave
junk in plane[1] when going from 2 plane to 1 plane format
v3: intel_check_plane_stride() was split out
v4: Drop the aligned viewport stuff, it was meant for ccs which
can't be remapped anyway
v5: Introduce intel_plane_can_remap()
Reorder the code so that plane_state->view gets filled
even for invisible planes, otherwise we'd keep using
stale values and could explode during remapping. The new
logic never remaps invisible planes since we don't have
a viewport, and instead pins the full fb instead
v6: Fix plane src coord checks after remapping by moving
plane_state->base.src to the final plane x/y offsets.
Allow intel_plane_check_stride() to fail even with
remapping (can happen at least with a linear 64bpp
fb with a 4k plane and a suitably inconvenient src
coordinates).
Improve aux plane FIXME (Daniel)
Move some code shuffling into a separate patch (Daniel)
