      drm/i915/display/psr: Use plane damage clips to calculate damaged area · 3fea9f42
      由 José Roberto de Souza 提交于 
      Now using plane damage clips property to calcualte the damaged area.
Selective fetch only supports one region to be fetched so software
needs to calculate a bounding box around all damage clips.

Now that we are not complete fetching each plane, there is another
loop needed as all the plane areas that intersect with the pipe
damaged area needs to be fetched from memory so the complete blending
of all planes can happen.

v2:
- do not shifting new_plane_state->uapi.dst only src is in 16.16 format

v4:
- setting plane selective fetch area using the whole pipe damage area
- mark the whole plane area damaged if plane visibility or alpha
changed

v5:
- taking in consideration src.y1 in the damage coordinates
- adding to the pipe damaged area planes that were visible but are
invisible in the new state

v6:
- consider old state plane coordinates when visibility changes or it
moved to calculate damaged area
- remove from damaged area the portion not in src clip

v7:
- intersec every damage clip with src to minimize damaged area

v8:
- adjust pipe_damaged area to 4 lines grouping
- adjust calculation now that is understood that uapi.src is the
framebuffer coordinates that plane will start to fetch from

v9:
- Only add plane dst or src to damaged_area if visible
- Early skip plane damage calculation if it was not visible in old and
new state

      drm/i915: Fix encoder lookup during PSR atomic check · 00e5deb5
      由 Imre Deak 提交于 
      The atomic check hooks must look up the encoder to be used with a
connector from the connector's atomic state, and not assume that it's
the connector's current attached encoder. The latter one can change
under the atomic check func, or can be unset yet as in the case of MST
connectors.

      drm/i915/tgl: Fix stepping WA matching · c33298cb
      由 José Roberto de Souza 提交于 
      TGL made stepping a litte mess, workarounds refer to the stepping of
the IP(GT or Display) not of the GPU stepping so it would already
require the same solution as used in commit 96c5a15f
("drm/i915/kbl: Fix revision ID checks").
But to make things even more messy it have a different IP stepping
mapping between SKUs and the same stepping revision of GT do not match
the same HW between TGL U/Y and regular TGL.

So it was required to have 2 different macros to check GT WAs while
for Display we are able to use just one macro that uses the right
revids table.

All TGL workarounds checked and updated accordingly.

v2:
- removed TODO to check if WA 14010919138 applies to regular TGL.
- fixed display stepping in regular TGL (Anusha)

      drm/i915/params: switch to device specific parameters · 8a25c4be
      由 Jani Nikula 提交于 
      Start using device specific parameters instead of module parameters for
most things. The module parameters become the immutable initial values
for i915 parameters. The device specific parameters in i915->params
start life as a copy of i915_modparams. Any later changes are only
reflected in the debugfs.

The stragglers are:

* i915.force_probe and i915.modeset. Needed before dev_priv is
  available. This is fine because the parameters are read-only and never
  modified.

* i915.verbose_state_checks. Passing dev_priv to I915_STATE_WARN and
  I915_STATE_WARN_ON would result in massive and ugly churn. This is
  handled by not exposing the parameter via debugfs, and leaving the
  parameter writable in sysfs. This may be fixed up in follow-up work.

* i915.inject_probe_failure. Only makes sense in terms of the module,
  not the device. This is handled by not exposing the parameter via
  debugfs.

      drm/dp: Introduce EDID-based quirks · 0883ce81
      由 Lyude Paul 提交于 
      The whole point of using OUIs is so that we can recognize certain
devices and potentially apply quirks for them. Normally this should work
quite well, but there appears to be quite a number of laptop panels out
there that will fill the OUI but not the device ID. As such, for devices
like this I can't imagine it's a very good idea to try relying on OUIs
for applying quirks. As well, some laptop vendors have confirmed to us
that their panels have this exact issue.

So, let's introduce the ability to apply DP quirks based on EDID
identification. We reuse the same quirk bits for OUI-based quirks, so
that callers can simply check all possible quirks using
drm_dp_has_quirk().

      drm/i915/psr: Force PSR probe only after full initialization · df1a5bfc
      由 José Roberto de Souza 提交于 
      Commit 60c6a14b ("drm/i915/display: Force the state compute phase
once to enable PSR") was forcing the state compute too earlier
causing errors because not everything was initialized, so here
moving to the end of i915_driver_modeset_probe() when the display is
all initialized.

Also fixing the place where it disarm the force probe as during the
atomic check phase errors could happen like the ones due locking and
it would cause PSR to never be enabled if that happens.
Leaving the disarm to the atomic commit phase, intel_psr_enable() or
intel_psr_update() will be called even if the current state do not
allow PSR to be enabled.

v2: Check if intel_dp is null in intel_psr_force_mode_changed_set()
v3: Check intel_dp before get dev_priv
v4:
- renamed intel_psr_force_mode_changed_set() to
intel_psr_set_force_mode_changed()
- removed the set parameter from intel_psr_set_force_mode_changed()
- not calling intel_psr_set_force_mode_changed() from
intel_psr_enable/update(), directly setting it after the same checks
that intel_psr_set_force_mode_changed() does
- moved intel_psr_set_force_mode_changed() arm call to
i915_driver_modeset_probe() as it is a better for a PSR call, all the
functions calls happening between the old and the new function call
will cause issue
