[PATCH 0/5] eDP improvements

[PATCH 0/5] eDP improvements

[Daniel Vetter]

Hi all,

This is useful fallout of my futile attempts at getting the eDP panel on my ivb
working without the BIOS' help. I now at least get a backlit black screen though
;-)

Paulo said that this is good enough for his hsw eDP machine already, and it
definitely improves the code a bit and (hopefully) makes it a tad more robust.

Comments, flames and test results highly welcome.

Cheers, Daniel

[PATCH 1/5] drm/i915: make edp panel power sequence setup more robust

[Daniel Vetter]

3 changes:
- If a given value is unset, use the maximal limits from the eDP spec.
- Write back the new values, since otherwise the panel power sequencing
  hw will not dtrt.
- Revert the early bail-out in case the register values are unset.

The last change reverts

    drm/i915: check PPS regs for sanity when using eDP

v2:
- Unlock the PP regs as the very first thing. This is a required w/a
  for cpu eDP on port A, and generally a good idea.
- Fixup the panel power control port selection bits.

v3: Paulo Zanoni noticed that I've fumbled the computation of the spec
limit values. Fix them up. We've also noticed that the t8/t9 values in
the vbt/bios-programmed pp are much larger than any limits. My guess
is that this is to conceal any backlight enable/disable delays. So by
using the much shorter limits from the spec, which only concerns the
sink, we risk that we might display before the backlight is fully on,
or disable the output while the backlight still has afterglow. I've
figured I don't care too much, since this will only happen when both
the pp regs are not programmed, and the vbt tables don't contain
anything useful.

v4: Don't set the port selection bits on hsw/LPT, they don't exist any
more.

settings only needs two "t"s.

If the current field is not zero and doesn't match the VBT, we might
add a debug statement.  It could indicate a BIOS programmed value that
didn't involve a VBT update (I can imagine some vendors might do
this).  Overwriting the current with the different VBT value may lead
to breakage or sub-optimal timings.

I really hate the inline macros, but that's just me.  It might be good
to factor out this stuff into a separate function too (I see you do
that in a later patch).  Assuming you take care of the above.

We dump the current values (read out from the PP regs), the vbt values
and now also the new values we write back into the regs. That not good
enough?

I suppose, it just means more digging if there's a mismatch.

[PATCH 2/5] drm/i915: enable/disable backlight for eDP

[Daniel Vetter]

Like we already do for the LVDS panels. This seems to help greatly
in setting up the backlight, since the BIOS might refuse to cooperate.

[PATCH 3/5] drm/i915/eDP: compute the panel power clock divisor from the pch rawclock

[Daniel Vetter]

We need this when the bios forgets even to set that bit up. Most seem
to do that, even when they don't set up anything else in the panel
power sequencer.

Note that on IBX the rawclk is variable according to Bspec, but
everyone is using 125MHz. The rawclk is fixed to 125MHz on CPT, but
luckily we still have the same register available. On hsw, different
variants have different clocks, hence we need to check the register.

Since other pieces are driven by the rawclock, too, keep the little
helper in a central place.

Did you check that the calculation generally matched the existing value
on the machines you looked at?

[PATCH 4/5] drm/i915/dp: compute the pch dp aux divider from the rawclk

[Daniel Vetter]

Otherwise dp aux won't work on some hsw platforms, since they use a
different rawclk than the 125MHz clock used thus far.

To absolutely not change anything, round up: That way we get the old
63 divider for the default 125MHz clock.

Re: [PATCH 0/5] eDP improvements

[Oleksij Rempel]

[-- Attachment #1: Type: text/plain, Size: 1453 bytes --]

Hi Daniel,

i assume this patch set should/may fix this bug:
https://bugs.freedesktop.org/show_bug.cgi?id=48652

i tested it on top of linux/master + drm-intel-fixes + "[PATCH] 
drm/i915/dp: actually nack test request".

eDP is listed now and xserver use it. But eDP stays blank/black.
I also got some warnings, see attached dmesg.

Yeah, you have the same issue as I do: eDP link training somehow fails.

Those are expected, since we turn off the edp port when the link
training fails, which means that the entire display pipeline stops.

Yes. With this series, the Kernel is able to enable the eDP panel even
when the BIOS does not enable it. A nice improvement!

Tested-by: Paulo Zanoni <paulo.r.zanoni@intel.com>

A few details:
- Due to the lack of more context lines, "git am" fails at properly
applying patch 02, so please make sure it compiles after you apply it
(the "int pipe" variable might be added to the wrong function)
- There's a small trivial conflict with patch 05 because dinq changed
since you submitted these.
- My Haswell eDP patches add another conflict, so I'm hoping you will
merge these before the actuall Haswell eDP patches.
