[Intel-gfx] [PATCH 00/89] Basic Skylake enabling (reviewers)

[Damien Lespiau]

Of course, the series now needs reviewers. There's a list of known
problems that I'm planning to address, a few of those problems are easy
to solve and ca be addressed as a new revision of those pathes. However
I'm hoping other ones can be follup up patches instead.


Known issues:

  - There a known limitation in the DDB allocation code. It doesn't
    respect the minimal allocation of 8 blocks. When we're trying to
    scannout two planes (not counting the cursor) that have widely
    different data rates (1080p and 64x64), we'll under-allocate the
    small plane and hit underuns.

    (follow up series)

  - There are a fair number of patches that are just "|| IS_GEN9(dev)".
    I'd do a "let's by optimistic" pass on the driver to turn those into
    "gen >= 9" to try to limit the number of small patches in the
    future.

    (follow up series)

  - I haven't done a pass of the W/A just yet, waiting for things to
    settle a bit. In particular I haven't checked that the few W/A
    implemented can be done in init_clock_gating() or needs to be LRIs.
    (the patch predates all of that).

    (follow up series)

  - While looking at the patches before sending, I've noticed some
    extraneous defines in "Fix the extra defines in "drm/i915/skl: Read
    the Memory Latency Values for WM computation".

    Will send a new version of this patch rigth away

  - There's potential to unify the primary and sprite planes functions
    now that the primary plane is just another plane. This needs a bit
    of work to unify those paths.

    My current plan is to address this as a follow up series, not high
    priority.

  - Daniel had a few comments piped up already, the bigger ones have been
    addressed. I, however didn't look at this one

    < danvet> edp unconditionally uses cdclk/dpll0
    < danvet> but we don't track the port clock for that anywhere in the pipe
              config


Reviewers

some of the patches already have a r-b tag, having another look has some
value as patches get rebased and churned a bit. Some people have 2 lines
below.  

I've left some people out of the list as they're just jumping on the
list and give feedback already. If you expect some big delays in the
review, please do speak up so I can try to find somebody else.

Patches  1 to 20, excluding 12: Thomas Wood

Patches 12 + 21 to 42: Rodrigo

Patches 43 to 52: Ville (WM)

Patches 53 to 56: Mika (forcewake engine + a bit of rc6)

Patch 57 is already merged

Patches 58 to 68: Paulo (DPLL + removal of the eDP training W/A)

Patches 69 to 73: Imre (Power wells)

Patches 74 to 75: Paulo (queue_flip, pfit)

Patches 76 to 83: Ville (WM part2)

Patch 84 to 89: Mika (turbo and various small patches, some of them already
                dropped and/or reviewed)

Thanks,
