[PATCH 0/7] sdvo tv clock improvements + some random stuff

[PATCH 0/7] sdvo tv clock improvements + some random stuff

[Daniel Vetter]

Hi all,

So I'm still blazing ahead with converting everything over to pipe_config. This
is (mostly) a tiny detour into sdvo TV support, which accidentally ended up
fixing a regression going back to the introduction of multi-function sdvo
support in 2.6.35.

Quick update on this pipe_config endeavour: I have a few more smaller things
outstanding around pll limits and handling that, but the big thing I'm currently
working on is beating sanity into our different clocks: dotclock, adjusted
dotclock, port clock (i.e. what we program the dpll with), reduced clock
versions of all of the above. Next up is handling dpll computation and clock
sharing.

Cheers, Daniel

[PATCH 1/7] drm/i915: simplify DP/DDI port width macros

[Daniel Vetter]

If we ever leak a non-DP compliant port width through here, we have a
pretty serious issue. So just rip out all these WARNs - if we need
them it's probably better to have them at a central place where we
compute the dp lane count.

Also use the new DDI width macro for FDI mode.

[PATCH 2/7] drm/i915: move sdvo TV clock computation to intel_sdvo.c

[Daniel Vetter]

We have a very nice infrastructure for this now!

Note that the multifunction sdvo support is pretty neatly broken: We
completely ignore userspace's request for which connector to wire up
with the encoder and just use whatever the last detect callback has
seen.

Not something I'll fix in this patch, but unfortunately something
which is also broken in the DDI code ...

v2: Don't call sdvo_tv_clock twice.

[PATCH 3/7] drm/i915: drop TVclock special casing on ilk+

[Daniel Vetter]

TV-out uses the same reference clock as everyone else. The only
difference seems to be in the slightly different CB tuning limit.

[PATCH 4/7] drm/i915: rip out TV-out lore ...

[Daniel Vetter]

This seems to be an impressive piece of copy&pasta lore. I've
checked all docs and on most platforms these bits are all MBZ, with
the exception of the SDVO pixel multiplier on gen3. On gen4 that
moved to a special DPLL_MD registers.

No indication whatsoever that we actually need this for native
TV-out support. I suspect this started as a hack when we didn't
yet have proper pixel multiplier support in place for SDVO TV, but
then got stuck in a life of its own.

Just rip it out.

We need to track this correctly. While at it shovel the boolean
to track whether the sdvo is in tv mode or not into pipe_config.

What is becoming less clear over time is what is derived state internal
to the modesetting sequence, and what is the state used to select a mode
e.g. to decide if two configs are compatible.

Atm everything is derived state and we currently have don't take the
pipe config into account for comparing state. My plan is that we
eventually add flags to the pipe_config compare function to decide
whether we need a full-blown modeset or can go with an "update pfit
state" fastpath.

So atm I'm just moving state around, since pipe_config will also be
used for atomic modeset. And checking the hw config upfront e.g. for
pll sharing has similar, but not completely overlapping needs to the
state comparison fastboot needs to do.

Another thing I don't yet have an opinion about is what we should do
if the mode matches, but the configuration details are a bit
suboptimal (like wasteful watermark settings). I guess we need to
rework the code so that we can fix this all up without stopping the
crtc. And there's tons of little bits of state like that (audio
config, infoframes, clock trees, watermarks, fdi config, ...). Added
fun is that often it is highly platform specific whether a given piece
of state must match for fastboot or not ...

My current plan is to just chip away with pipe_config conversions,
with more a focus towards atomic modeset (i.e. upfront checking),
leaving some of the harder fastboot issues for Jesse ;-)

Cheers, Daniel

And now that I've actually booted a Kernel with the patch I see that
the chunk inside intel_ddi_enable_transcoder_func is wrong. We should
assign to the "temp" variable, not "intel_dp->DP". This gives me a
nice black screen on DP.

Yeah, I've copy&pasted the wrong bugzilla link, that's the 2nd one.

With this change, is_sdvo and is_tv are no longer used, and could be
dropped from the function. All the same,

An observation, this code path is actually dead code for ilk+, as is the
else if (is_tv) branch below. Good riddance.

The commit message could reflect that this is actually a reserved value

I found a g45 spec saying this about bits 7:0 on CTG:

"FPB1 P1 Post Divisor: Writes to this byte cause the staging register
 contents to be written into the active register when in the VGA mode of
 operation. This will also occur when the VGA MSR register is written."

Additionally 3 is an illegal value...
