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)

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.

On future platforms the index of the color-clear plane will change from
the one used by the GEN12 RC CCS CC modifier, so add a way to retrieve
the index independently of the platform/modifier.

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.

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)

This reverts commit 05734ca2a8f76c9eb3890b3c9dfc3467f03105c1.
It's not graceful, instead it leads to boot time warning splats in the
case it is supposed to handle gracefully. Apparently the BIOS/GOP
enabling the port we end up skipping leads to state readout
problems. Back to the drawing board.

[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.

Just like we do for internal objects. Also just use
i915_gem_object_set_cache_coherency() here. No need for over-flushing on
LLC platforms.

While the pages can't be swapped out, they can be discarded by the shrinker.
Normally such objects are marked with __I915_MADV_PURGED, which can't be
unset, and therefore requires a new object. For kernel internal objects
this is not true, since the madv hint is reset for our special volatile
objects, such that we can re-acquire new pages, if so desired, without
needing a new object. As a result we should probably be paranoid here
and put the object back into the CPU domain when discarding the pages,
and also correctly set cache_dirty, if required.

Add some details around non-LLC platforms and cflushing, when dealing
with the flush-on-acquire, which is potentially security sensitive.

On non-LLC platforms, force the flush-on-acquire if this is ever
swapped-in. Our async flush path is not trust worthy enough yet(and
happens in the wrong order), and with some tricks it's conceivable for
userspace to change the cache-level to I915_CACHE_NONE after the pages
are swapped-in, and since execbuf binds the object before doing the
async flush, there is a potential race window.

Even though userptr objects are always coherent with the GPU, with no
way for userspace to change this with the set_caching ioctl, even on
non-LLC platforms, there is still the 'Bypass LCC' mocs setting, which
might permit reading the contents of main memory directly.

As pointed out by Thomas, we likely need to flush the pages here if the
GPU can read the page contents directly from main memory. Underneath we
don't know what the sg_table is pointing to, so just add a
wbinvd_on_all_cpus() here, for now.

These are userspace objects, so mark them as such. In a later patch it's
useful to determine how paranoid we need to be when managing cache
flushes. In theory no functional changes.
