[PATCH v10 1/2] drm: Introduce new DRM_FORMAT_XYUV

[Stanislav Lisovskiy]

v5: This is YUV444 packed format same as AYUV, but without alpha,
    as supported by i915.

v6: Removed unneeded initializer for new XYUV format.

v7: Added is_yuv field initialization according to latest
    drm_fourcc format structure initialization changes.

v8: Edited commit message to be more clear about skl+, renamed
    PLANE_CTL_FORMAT_AYUV to PLANE_CTL_FORMAT_XYUV as this format
    doesn't support per-pixel alpha. Fixed minor code issues.

v9: Moved DRM format check to proper place in intel_framebuffer_init.

[PATCH v10 2/2] drm/i915: Adding YUV444 packed format support for skl+

[Stanislav Lisovskiy]

PLANE_CTL_FORMAT_AYUV is already supported, according to hardware
specification.

v2: Edited commit message, removed redundant whitespaces.

v3: Fixed fallthrough logic for the format switch cases.

v4: Yet again fixed fallthrough logic, to reuse code from other case
    labels.

v5: Started to use XYUV instead of AYUV, as we don't use alpha.

v6: Removed unneeded initializer for new XYUV format.

v7: Added scaling support for DRM_FORMAT_XYUV

v8: Edited commit message to be more clear about skl+, renamed
    PLANE_CTL_FORMAT_AYUV to PLANE_CTL_FORMAT_XYUV as this format
    doesn't support per-pixel alpha. Fixed minor code issues.

v9: Moved DRM format check to proper place in intel_framebuffer_init.

v10: Added missing XYUV format to sprite planes for skl+.

Ping. There is an IGT patch which got Reviewed-by Ville.
This one left in order to get XYUV support.

Did we figure out userspace for this?

Was the conflict solved with the other guy (forgot who it is)
trying to add the same format with a different name?

Currently for userspace we have VLC(checked with Juha-Pekka) and
also IGT test case.

I think those guys were from ARM and they were adding also support for
XYUV. The only difference was that they called XYUV, like XYUV8888
something. 
Our patches were otherwise identical regarding drm_fourcc.c part, I
don't see their stuff merged, but I guess it really shouldn't matter,
who does this first. i915 specific part doesn't conflict with their
stuff. To be honest, I forgot the guy's name neither could find his
email in my mailbox. 
So hopefully somebody shows up here.

Yes, that's me.
Not a real conflict here, as long as your patches are ready to be
merged feel free to do it and I will just rebase my series on top of
that.

I can change DRM_FORMAT_XYUV naming to DRM_FORMAT_XYUV8888 also, so
that my patch series then is compatible with yours.

Hei, no. VLC was *not* showing the mode correctly back then when we 
tested. VLC kms plugin is able to initialize the mode and it's all 
stable but VLC didn't have correct video converter to reach matching 
xYUV output. You remember Stan we tried to increase the recursion for 
decoding in case it would help? VLC doesn't have codec which produce 
correct output, one of those xxx -> YUV plug-ins in VLC should be 
patched before VLC can be considered as userspace for this mode.

Ok, I remember we managed to make it work somehow and saw some picture,
so for some reason I thought it is working already. What is our plan
then? Should we try to improve VLC codecs/plugins or may be I should
then work with some other user space case?

For VLC there are codecs which know about xYUV format but they seem to 
use it for input, I figure nobody so far needed it for output. If want 
to use VLC as userspace demo one of those codecs need to be patched up 
for outputting xYUV. As they already support many other YUV formats I 
wouldn't expect needed change to be significant on code level as KMS 
support is already in VLC.
