Question about drm-intel-next vs drm-intel-next-fixes for HDMI scrambling patch

[Jerome Tollet]

Hi Jani,

I would like to better understand the i915 patch flow, rather than question
the decision itself.

The commit b7d51d65e4f1 ("drm/i915/hdmi: Poll for 200 msec for
TMDS_Scrambler_Status") was pushed to drm-intel-next on June 11. It was then
included in the July 2 drm-intel-next pull, described as the first feature
pull towards v7.3.

However, it was not included in the drm-intel-next-fixes pulls for v7.2,
including the June 25 pull, and it is consequently not present in v7.2-rc5.

Could you please explain how the decision is made to route a patch to
drm-intel-next versus drm-intel-next-fixes? In this particular case, was
there a technical or review reason why the patch was not considered for the
v7.2 fixes pull, or was it mainly a timing/queueing decision?

I am asking to understand the process for future contributions.

Thanks,
Jerome

All i915 patches get applied to drm-intel-next first, and fixes are
cherry-picked to drm-intel-fixes/drm-intel-next-fixes based on Fixes:
and Cc: stable trailers. In this case, the patch had neither, and none
were added while applying the patch.

It can still be cherry-picked for drm-intel-fixes if necessary.


BR,
Jani.
