Hi,

Here is a first attempt at expanding the current Chamelium formats
test to YUV formats.

It builds on top of the current infrastructure for the YUV convertions, and
the format suppport of the Chamelium. It reworks igt_fb quite significantly
to add generic support for YUV formats, and adds a bunch of new formats
along the way.

Let me know what you think,
Maxime

Changes from v5:
- Fixed breakage on x86 platforms
- Fixed typo in a comment
- Split the size and strides check in a separate patch
- Added the various tags from Lyude and Paul
- Rebased on master

Changes from v4:
- Added Paul Reviewed-by's
- Removed the patch that moves calc_fb_size for everybody, and added some
asserts

Changes from v3:
- Fixed build breakage

Changes from v2:
- Added Paul Reviewed-by's
- Fixed a stride issue on the buffer allocation
- Take into account the plane bpp so that we don't overallocate
- Rebased on master

Changes from v1:
- Support more YUV formats than just NV12
- Rework the YUV convertion functions to add generic routines
- Took the comments into account.

Maxime Ripard (10):
igt: fb: Refactor dumb buffer allocation path
igt: fb: Add size checks and recalculation before dumb allocation
igt: fb: Account for all planes bpp
igt: fb: Don't pass the stride when allocating a dumb, multi-planar
buffer
igt: fb: Clear YUV dumb buffers
igt: fb: Rework YUV i915 allocation path
igt: fb: Add a bunch of new YUV formats
igt: tests: chamelium: Start to unify tests
igt: tests: chamelium: Convert VGA tests to do_test_display
igt: tests: chamelium: Add YUV formats tests
