6f2f7c8330 Merge tag 'drm-intel-gt-next-2021-10-21' of git://anongit.freedesktop.org/drm/drm-intel into drm-next 
UAPI Changes:

- Expose multi-LRC submission interface

  Similar to the bonded submission interface but simplified.
  Comes with GuC only implementation for now. See kerneldoc
  for more details.

  Userspace changes: https://github.com/intel/media-driver/pull/1252

- Expose logical engine instance to user

  Needed by the multi-LRC submission interface for GuC

  Userspace changes: https://github.com/intel/media-driver/pull/1252

Driver Changes:

- Fix blank screen booting crashes when CONFIG_CC_OPTIMIZE_FOR_SIZE=y (Hugh)
- Add support for multi-LRC submission in the GuC backend (Matt B)
- Add extra cache flushing before making pages userspace visible (Matt A, Thomas)
- Mark internal GPU object pages dirty so they will be flushed properly (Matt A)

- Move remaining debugfs interfaces i915_wedged/i915_forcewake_user into gt (Andi)
- Replace the unconditional clflushes with drm_clflush_virt_range() (Ville)
- Remove IS_ACTIVE macro completely (Lucas)
- Improve kerneldocs for cache_dirty (Matt A)

- Add missing includes (Lucas)
- Selftest improvements (Matt R, Ran, Matt A)

bb115220d2 drm/i915/hdmi: Introduce intel_hdmi_is_ycbr420() 
Introduce a small helper which given the crtc state tells us
whether we're output YCbCr 4:2:0 or not. For native HDMI this
is rather simple as we just look at the output_format. But I
think the helper is beneficial since with DP HDMI DFPs we're
going to need a more complex variant, and I want to unify the
DP and HDMI sides of that as much as possible.

3cf460bd68 drm/i915/hdmi: Split intel_hdmi_bpc_possible() to source vs. sink pair 
intel_hdmi_bpc_possible() is used by the DP code as well where
the native HDMI source limits do not apply. So let's split this
into a pair of functions: one for the source vs. one for the sink.

This is basically reverting some of commit 41828125ac ("drm/i915:
Move platform checks into intel_hdmi_bpc_possible()") slightly,
but in a nicer form. I guess I forgot at the time that the DP side
uses this too.

f504234361 drm/i915: Add a platform independent way to check for CCS AUX planes 
Future platforms change the location of CCS AUX planes in CCS
framebuffers, so add intel_fb_is_ccs_aux_plane() to query for these
planes independently of the platform. This function can be used
everywhere instead of is_ccs_plane() (or is_ccs_plane() && !cc_plane()),
since all the callers are only interested in CCS AUX planes (and not CCS
color-clear planes).

Add the corresponding intel_fb_is_gen12_ccs_aux_plane(), which can be
used everywhere instead of is_gen12_ccs_plane(), based on the above
explanation.

This change also unexports the is_gen12_ccs_modifier(),
is_gen12_ccs_plane(), is_gen12_ccs_cc_plane() functions as they are only
used in intel_fb.c

v1-v2: Unchanged
v3: (Ville)
- Use ccs_aux instead of the ccs_ctrl term everywhere.
- Use color_plane instead of plane term for FB plane indicies.
v4: Fix version range check. (Jani)

df63860da9 drm/i915: Handle CCS CC planes separately from CCS AUX planes 
CCS CC planes are quite different from CCS AUX planes, even though we
regard the CC planes as a linear buffer having a 64 byte stride.  Thus
it's clearer to check for either CCS plane types explicitly when we need
to handle them; add the required CCS CC planes check here, while the
next patch will change all is_ccs_plane()/is_gen12_ccs_plane() checks to
consider only the CCS AUX planes.

0f2922ef48 drm/i915: Move intel_format_info_is_yuv_semiplanar() to intel_fb.c 
Move intel_format_info_is_yuv_semiplanar() to intel_fb.c . The number of
planes for YUV semiplanar formats using CCS modifiers will change on
future platforms. We can use the modifier descriptors to simplify
getting the plane numbers for all modifiers, prepare for that here.

e2b8329432 drm/i915: Add a table with a descriptor for all i915 modifiers 
Add a table describing all the framebuffer modifiers used by i915 at one
place. This has the benefit of deduplicating the listing of supported
modifiers for each platform and checking the support of these modifiers
on a given plane. This also simplifies in a similar way getting some
attribute for a modifier, for instance checking if the modifier is a
CCS modifier type.

While at it drop the cursor plane filtering from skl_plane_has_rc_ccs(),
as the cursor plane is registered with DRM core elsewhere.

v1: Unchanged.
v2:
- Keep the plane caps calculation in the plane code and pass an enum
  with these caps to intel_fb_get_modifiers(). (Ville)
- Get the modifiers calling intel_fb_get_modifiers() in i9xx_plane.c as
  well.
v3:
- s/.id/.modifier/ (Ville)
- Keep modifier_desc vs. plane_cap filter conditions consistent. (Ville)
- Drop redundant cursor plane check from skl_plane_has_rc_ccs(). (Ville)
- Use from, until display version fields in modifier_desc instead of a mask. (Jani)
- Unexport struct intel_modifier_desc, separate its decl and init. (Jani)
- Remove enum pipe, plane_id forward decls from intel_fb.h, which are
  not needed after v2.
v4:
- Reuse IS_DISPLAY_VER() instead of open-coding it. (Jani)
- Preserve the current modifier order exposed to user space. (Ville)
v5: Use }, { on one line to seperate the descriptor array elements. (Jani)

dd8cb18906 drm/amd/display: Increase watermark latencies for DCN3.1 
[why]
The original latencies were causing underflow in some modes

[how]
Replace with the up-to-date watermark values based on new measurments

4835ea6c17 drm/amd/display: increase Z9 latency to workaround underflow in Z9 
[Why]
Z9 latency is higher than when we originally tuned the watermark
parameters, causing underflow. Increasing the value until the latency
issues is resolved.

672437486e drm/amd/display: Require immediate flip support for DCN3.1 planes 
[Why]
Immediate flip can be enabled dynamically and has higher BW requirements
when validating which voltage mode to use.

If we validate when it's not set then potentially DCFCLK will be too low
and we will underflow.

[How]
DM always requires support so always require it as part of DML input
parameters.

This can't be enabled unconditionally on older ASIC because it blocks
some expected modes so only target DCN3.1 for now.

c938aed88f drm/amd/display: Fix prefetch bandwidth calculation for DCN3.1 
[Why]
Prefetch BW calculated is lower than the DML reference because of a
porting error that's excluding cursor and row bandwidth from the
pixel data bandwidth.

[How]
Change the dml_max4 to dml_max3 and include cursor and row bandwidth
in the same calculation as the rest of the pixel data during vactive.

i915_gem_object_set_cache_coherency() here. No need for over-flushing on
LLC platforms.
