[Intel-gfx] [PATCH 00/12] drm/i915: More VBT stuff

[Intel-gfx] [PATCH 00/12] drm/i915: More VBT stuff

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Bunch of VBT work:
- cleanup of version number comments
- document more bits
- rename a few misnamed things
- warn if any port wants to use the VBT vswing tables
- parse the new DP lane count limit

Ville Syrjälä (12):
  drm/i915: Unify VBT version number comments
  drm/i915: Add some more VBT version number comments
  drm/i915: Properly define the DP redriver VBT bits
  drm/i915: Define VBT eDP/DP max lane count bits
  drm/i915: Add the VBT LTTPR transparent vs. non-transparent bits
  drm/i915: Define VBT max HDMI FRL rate bits
  drm/i915: Document the sets of bits in the driver features block
  drm/i915: Define more VBT driver features block bits
  drm/i915: Define all possible VBT device handles
  drm/i915: Rename some VBT bits
  drm/i915: WARN if a port should use VBT provided vswing tables
  drm/i915: Parse DP/eDP max lane count from VBT

[Intel-gfx] [PATCH 01/12] drm/i915: Unify VBT version number comments

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Use a more standard form for the VT version number comments.

Had to do some digging for this one.

So the story is that the field was introduced in 216 but
then they totally changed the meaning of the bits in 230.
See parse_bdb_216_dp_max_link_rate() vs.
parse_bdb_230_dp_max_link_rate(). But naturally the current
version of the spec totally fails to mention this. Sigh.

The GLK comment originally said CNL (it got changed during mass
rename when CNL stuff was dropped), and that was just based on
a note in the spec at the time that said the field is valid for
CNL+. Whether that actually included GLK or not is not at all
clear.

Also currently we parse this for everything so it's not super
obvious if we're accidentlaly parsing it on platforms where
it should not be used. But that should actually be fine since
the value should then be 0 which either means 8.1Gbps or
"no limit" which should not therefore impose any accidental
limit on anything.

I should probably put some of that into the commit message
for posterity...

That's 155 in current bspec as well as some old doc I had.

VBT gained a bit to indicate whether LTTPRs should use transparent

[Intel-gfx] [PATCH 06/12] drm/i915: Define VBT max HDMI FRL rate bits

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

The VBT gained some bits to inidicate the max FRL rate for
HDMI 2.1, define them.

These just outright replaced the slave_port bits for ganged eDP.
Apparently that feature was never actually used so someone decided
that reusing the bits is fine. Although the actual ganged eDP
enable bit was still left defined elsewhere for some reason.

[Intel-gfx] [PATCH 11/12] drm/i915: WARN if a port should use VBT provided vswing tables

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We don't parse the VBT vswing/preemphassis tables at all currently.
Let's WARN if a port wants to use them so we get a heads up that
whether we really need to implement this stuff or not. My
current stash contains no VBTs with this bit set.

let's unlock a new can of worms?! :)

I believe this deserves a /* XXX: comment with the code in case
someone else finds this warns first and doesn't use the git blame

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Limit the DP lane count based on the new VBT DP/eDP max
lane count field.

do we really need 2 functions here since this one is small and we don't have any
bit switches and all?!
or do you plan to reuse this anywhere else later?

This is modelled after the other similar functions. I think Jani had
some plans for cleaning up a lot of this stuff, but dunno how far we
are on that path.

They just won't learn that non-zero is a really crappy "default" to
set. *sigh*

A bit stalled. Eventually I'd like all encoders to have encoder->devdata
and callers would pass that instead of encoder, and we wouldn't have
this i915->vbt.ports[encoder->port]; lookup.

But the first function could be used in print_ddi_port() for printing
the info while the latter couldn't. So I kinda prefer the split.
