[Intel-gfx] [PATCH 00/18] Haswell eDP enablement v3

[Paulo Zanoni]

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

Hi

Here is the third version, which is the result of the discussions I had with
Daniel both on the mailing list and on IRC.

In my discussions with Daniel we were wondering about code that would or would
not be run on VGA (the only output that requires the PCH), so what I actually
did was an attempt to fix VGA and see what changes would really be needed on our
PCH code. After my investigation I partially fixed our VGA support (some modes
still didn't work) but it was enough to get a clear idea of what we would need
to do with the PCH/FDI code. The "partially fix VGA" series will come later.

So this new series contains 4 new patches at its beginning. These patches do
some small adjustments to consider the fact that we only have 1 PCH transcoder
on Haswell. This way we can avoid running PCH/FDI code on eDP, allowing us to
port even less code to use cpu_transcoder instead of pipe, possibly making
Daniel happier.

Comments? Reviews?

Thanks,
Paulo
