We link every DRM "file_priv" to a "drm_master" structure. Currently, the
drmSetMaster() call returns 0 when there is _any_ active master associated
with the "drm_master" structure of the calling "file_priv". This means,
that after drmSetMaster() we are not guaranteed to be DRM-Master and might
not be able to perform mode-setting.
A way to reproduce this is by starting weston with the DRM backend from
within an X-console (eg., xterm). Because the xserver's "drm_master" is
currently active, weston is assigned to the same master but is inactive
because its VT is inactive and the xserver is still active. But when
"fake-activating" weston, it calls drmSetMaster(). With current behavior
this returns "0/success" and weston thinks that it is DRM-Master, even
though it is not (as the xserver is still DRM-Master).
Expected behavior would be drmSetMaster() to return -EINVAL, because the
xserver is still DRM-Master. This patch changes exactly that.
The only way this bogus behavior would be useful is for clients to check
whether their associated "drm_master" is currently the active DRM-Master.
But this logic fails if no DRM-Master is currently active at all. Because
then the client itself would become DRM-Master (if it is root) and this
makes this whole thing useles.
Also note that the second "if-condition":
file_priv->minor->master != file_priv->master
is always true and can be skipped.

This commit makes hsw_fdi_link_train responsible for implementing
everything described in the "Enable and train FDI" section from the
Hawell CRT mode set sequence documentation. We completely rewrite
hsw_fdi_link_train to match the documentation and we also call it in
the right place.
This patch was initially sent as a series of tiny patches fixing every
little problem of the function, but since there were too many patches
fixing the same function it got a little difficult to get the "big
picture" of how the function would be in the end, so here we amended
all the patches into a single big patch fixing the whole function.
Problems we fixed:
1 - Train Haswell FDI at the right time.
We need to train the FDI before enabling the pipes and planes, so
we're moving the call from lpt_pch_enable to haswell_crtc_enable
directly.
We are also removing ironlake_fdi_pll_enable since the PLL
enablement on Haswell is completely different and is also done
during the link training steps.
2 - Use the right FDI_RX_CTL register on Haswell
There is only one PCH transcoder, so it's always _FDI_RXA_CTL.
Using "pipe" here is wrong.
3 - Don't rely on DDI_BUF_CTL previous values
Just set the bits we want, everything else is zero. Also
POSTING_READ the register before sleeping.
4 - Program the FDI RX TUSIZE register on hsw_fdi_link_train
According to the mode set sequence documentation, this is the
right place. According to the FDI_RX_TUSIZE register description,
this is the value we should set.
Also remove the code that sets this register from the old
location: lpt_pch_enable.
5 - Properly program FDI_RX_MISC pwrdn lane values on HSW
6 - Wait only 35us for the FDI link training
First we wait 30us for the FDI receiver lane calibration, then we
wait 5us for the FDI auto training time.
7 - Remove an useless indentation level on hsw_fdi_link_train
We already "break" when the link training succeeds.
8 - Disable FDI_RX_ENABLE, not FDI_RX_PLL_ENABLE
When we fail the training.
9 - Change Haswell FDI link training error messages
We shouldn't call DRM_ERROR when still looping through voltage
levels since this is expected and not really a failure. So in this
commit we adjust the error path to only DRM_ERROR when we really
fail after trying everything.
While at it, replace DRM_DEBUG_DRIVER with DRM_DEBUG_KMS since
it's what we use everywhere.

drm/i915: export a CPT mode set verification function
Note that this old code has unconditionally set the w/a, which might
explain why fdi link training sometimes silently fails, and especially
why the auto-train did not seem to work properly.
v3: Paulo Zanoni pointed out that this workaround is also required on
the LPT PCH. And Arthur Ranyan confirmed that this workaround is
requierd for all ports on the pch, not just DP: The important part
is that the bit is set whenever the pch transcoder is enabled, and
that it is _not_ set while the fdi link is trained. It is also
important that the pch transcoder is fully disabled, i.e. we have to
wait for bit 30 to clear before clearing the w/a bit.
Hence move to workaround into enable/disable_transcoder, where the pch
transcoder gets enabled/disabled.
v4: Whitespace changes dropped.
v5: Don't run the w/a on IBX, we only need it on CPT/PPT and LPT.
v6:

- s/!IBX/CPT since hsw paths are now all separate, and Paulo's patch

drm/i915: Initialize LVDS and eDP outputs before anything else
simply because it doesn't scale: It misses SDVO and DVO panels,
and now with DDI encoders on haswell this is becoming unmanageable.
Instead we simply sort the connector list after everything is

Now intel_ddi_init is just like intel_hdmi_init and intel_dp_init: it
inits the encoder and then calls the proper init_connector functions.
Notice that for non-eDP ports we call both HDMI and DP connector init,
so we have 2 connectors attached to each DDI encoder.
After this change, intel_hdmi_init and intel_dp_init are only called
by Ivy Bridge and earlier, while hardware containing DDI outputs
should call intel_ddi_init.
Also added/removed quite a few "static" keywords due to the fact that
some function pointers were moved from intel_dp.c and intel_hdmi.c to
intel_ddi.c.

actually have two connectors attached to it: HDMI and DP.

The goal is to have one single encoder capable of controlling both DP
and HDMI outputs. This patch just adds the initial infrastructure, no
functional changes.
Previously, both intel_dp and intel_hdmi were intel_encoders. Now,
these 2 structs do not have intel_encoder as members anymore. The new
struct intel_digital_port has intel_encoder as a member, and it also
includes intel_dp and intel_hdmi as members. In other words: see the
changes inside intel_drv.h: it's the most important change, everything
else is only to make it compile and work.
For now, each intel_digital_port is still only able to control one of
HDMI or DP, but not both together.
In the future we should also try to merge the common fields from
intel_dp and intel_hdmi (e.g., port).
