[Intel-gfx] [PATCH 0/9] Haswell DDI encoder (DP + HDMI on the same port)

[Paulo Zanoni]

From: Paulo Zanoni <paulo.r.zanoni at intel.com>

Hi

Finally, the last piece of the Haswell DP enablement: after this series xrandr
should show your connected DP monitors and hopefully enable them.

The problem this series tries to solve is that both DP and HDMI share the same
registers for any given port. So you can't just "intel_hdmi_init(PORT_A)" and
then "intel_dp_init(PORT_A)", as this will totally confuse the HW state readout
code, among other things.

Older versions of these patches (and all the previous ones I sent in the last
weeks) were already used by quite a few people and even tested by QA a few
times.

The amount of lines changed by this series is quite big, but most of these
changes are small adjustments to make the code compile. Because of this, as our
tree changes (especially intel_hdmi.c and intel_dp.c) these patches may start
needing some adjustments. I wrote these patches on top of today's
drm-intel-next-queued + the 3 "edp panel scaling" patches from Jani/Yuly (since
I believe these will probably get merged before my series, so I won't have to
resend in this case).

After this series I still have 2 more series to send, one with Haswell VGA fixes
and the other with small Haswell bug fixes.

Thanks in advance for your reviews,
Paulo
