069b78f5d1 drm/i915/dp: Respect the sink's max TMDS clock when dealing with DP->HDMI DFPs 
Currently we only look at the DFPs max TMDS clock limit when
considering whether the mode is valid, or whether we can do
deep color. The sink's max TMDS clock limit may be lower than
the DFPs, so we need to account for it as well.

055634e4b6 drm/i915: Expose client engine utilisation via fdinfo 
Similar to AMD commit
8744425411 ("drm/amdgpu: Add show_fdinfo() interface"), using the
infrastructure added in previous patches, we add basic client info
and GPU engine utilisation for i915.

Example of the output:

  pos:    0
  flags:  0100002
  mnt_id: 21
  drm-driver: i915
  drm-pdev:   0000:00:02.0

  drm-engine-render:  9288864723 ns
  drm-engine-copy:    2035071108 ns
  drm-engine-video:   0 ns
  drm-engine-video-enhance:   0 ns

v2:
 * Update for removal of name and pid.

v3:
 * Use drm_driver.name.

v4:
 * Added drm-engine-capacity- tag.
 * Fix typo. (Umesh)

v5:
 * Don't output engine data before Gen8.

bb6287cb18 drm/i915: Track context current active time 
Track context active (on hardware) status together with the start
timestamp.

This will be used to provide better granularity of context
runtime reporting in conjunction with already tracked pphwsp accumulated
runtime.

The latter is only updated on context save so does not give us visibility
to any currently executing work.

As part of the patch the existing runtime tracking data is moved under the
new ce->stats member and updated under the seqlock. This provides the
ability to atomically read out accumulated plus active runtime.

v2:
 * Rename and make __intel_context_get_active_time unlocked.

v3:
 * Use GRAPHICS_VER.

50203b943b drm/i915: Change SDVO fixed mode handling 
SDVO is the only connector type currently returning the VBT
fixed mode directly from .get_modes(), everyone else just
adds it to the fixed_modes list and then returns that from

7a36980cd2 drm/i915: Use intel_panel_edid_fixed_mode() for sdvo 
Despite the name intel_panel_edid_fixed_mode() doesn't actually
look in the EDID. All it does is dig out the preferred mode from
the connector's probed_modes list. That is also what the SDVO
LVDS code is doing by hand. Let's just call
intel_panel_edid_fixed_mode().

The slight difference in behaviour is that the SDVO code currently
bails if it can't find the preferred mode, whereas
intel_panel_edid_fixed_mode() will fall back to just returning
the first mode from the probed_modes list. Can't imagine why
such an LVDS panel would even exist, and also why would you have
a panel and be expected to not use it? So I'm going to assume
this is a total non-issue.
