Chris Wilson 3466a3def2 drm/i915/gt: Cleanup heartbeat systole first
Before we grab the engine wakeref, tidy up the previous heartbeat
request. If we then abort because the engine powerwell is off, we ensure
the request is freed as we know we will not have freed it when
cancelling the work (as the work is running!).

Chris Wilson 841e867286 drm/i915/gt: Only drop heartbeat.systole if the sole owner
Mika spotted that only using cancel_delayed_work() could mean that we
attempted to clear the heartbeat.systole while the worker was still
running. Rectify the situation by only touching the systole from outside
the worker if we suceeded in cancelling the worker before it could run.
The worker is expected to clean up by itself upon idling.

Ville Syrjälä 1e460bf9ea drm/i915: Frob the correct crtc state in intel_crtc_disable_noatomic()
The uapi vs. hw state split introduced a bug in
intel_crtc_disable_noatomic() where it's now frobbing an already
freed temp crtc state instead of adjusting the crtc state we
are really left with. Fix that by making a cleaner separation
beteen the two.

This causes explosions on any machine that boots up with pipes
already running but not hooked up to any encoder (typical
behaviour for gen2-4 VBIOS).

If the device does not have an aperture through which we can indirectly

extend the ioctl to support different modes, but as an extension the
user must opt in and explicitly control the mmap type (viz
MMAP_OFFSET_IOCTL).

Jani Nikula 59ed05ccdd drm/i915: update rawclk also on resume
Since CNP it's possible for rawclk to have two different values, 19.2
and 24 MHz. If the value indicated by SFUSE_STRAP register is different
from the power on default for PCH_RAWCLK_FREQ, we'll end up having a
mismatch between the rawclk hardware and software states after
suspend/resume. On previous platforms this used to work by accident,
because the power on defaults worked just fine.

Update the rawclk also on resume. The natural place to do this would be
intel_modeset_init_hw(), however VLV/CHV need it done before
intel_power_domains_init_hw(). Thus put it there even if it feels
slightly out of place.

v2: Call intel_update_rawclck() in intel_power_domains_init_hw() for all
    platforms (Ville).

After the reset, we do another clflush before checking the CSB to be

unlikely to be an incoherent view of the CSB, and more likely that
Icelake didn't reset its pointers.

Chris Wilson c601cb2135 drm/i915: Defer rc6 shutdown to suspend_late
Currently we shutdown rc6 during i915_gem_resume() but this is called
during the preparation phase (i915_drm_prepare) for all suspend paths,
but we only want to shutdown rc6 for S3+. Move the actual shutdown to
i915_gem_suspend_late().

We then need to differentiate between suspend targets, to distinguish S0
(s2idle) where the device is kept awake but needs to be in a low power
mode (the same as runtime suspend) from the device suspend levels where
we lose control of HW and so must disable any HW access to dangling
memory.

Maarten Lankhorst 1f594b209f drm/i915: Remove special case slave handling during hw programming, v3.
Now that we split plane_state which I didn't want to do yet, we can
program the slave plane without requiring the master plane.

This is useful for programming bigjoiner slave planes as well. We
will no longer need the master's plane_state.

Changes since v1:
- set src/dst rectangles after copy_uapi_to_hw_state.
Changes since v2:
- Use the correct color_plane for pre-gen11 by using planar_linked_plane != NULL.
- Use drm_format_info_is_yuv_semiplanar in skl_plane_check() to fix gen11+.

Maarten Lankhorst 380015bfd9 drm/i915: Complete plane hw and uapi split, v2.
Splitting plane state is easier than splitting crtc_state,
before plane check we copy the drm properties to hw so we can
do the same in bigjoiner later on.

We copy the state after we did all the modeset handling, but fortunately
i915 seems to be split correctly and nothing during modeset looks
at plane_state.

Changes since v1:
- Do not clear hw state on duplication.

before color management is checked.

Changes since v1:

- Clear crtc_state->hw on disable, instead of using clear_intel_crtc_state().
Changes since v2:
- Use intel_crtc_free_hw_state + clear in intel_crtc_disable_noatomic().
- Make a intel_crtc_prepare_state() function that clears the crtc_state
  and copies hw members.
- Remove setting uapi.adjusted_mode, we now have a direct call to
  drm_calc_timestamping_constants().
Changes since v3:
- Rename prefix copy_hw_to_uapi_state() with intel_crtc.
- Copy color blobs to uapi as well.
- Add a intel_crtc_copy_uapi_to_hw_state_nomodeset() function for clarity.
Changes since v4:
