bbd57d16d5 drm/i915/rps/tgl+: Remove RPS interrupt support
TGL+ and newer platforms don't support RPS up and low interruption
limits.
It is not used for broadwell and newer plaforms that supports
execlist but here making sure that it is explicit not used even in

b9ef89392c drm/i915/tgl: Simply subplatform detection
In the past we had a need to differentiate TGL U and TGL Y, there
was a different voltage swing table for each subplatform and some PCI
ids of this subplatforms are shared but it turned out that it was a
specification mistake and the voltage swing table was indeed the same
but we went ahead with that patch because we needed to differentiate
TGL U and Y from TGL H and by that time TGL H was embargoed so that
was the perfect way to land it upstream.

Now the embargo for TGL H is long past and now we even have
INTEL_TGL_12_GT1_IDS with all TGL H ids, so we can drop this PCI root
check and only rely in the PCI ids to differentiate TGL U and Y from
TGL H that actually has code differences.

Besides the simplification this will fix issues in virtualization
environments where the PCI root is virtualized and don't have the same
id as actual hardware.

v2:
- add and set INTEL_SUBPLATFORM_UY

d95c25668f drm/i915: Properly clear crtc state when disabling it fully, again
Currently we just leave the old gunk lying around in the crtc
state when userspace asks us to fully disable the crtc. That
doesn't match what the state would be had we never even enabled
the crtc in the first place. So let's make this consistent and
call intel_crtc_prepare_cleared_state() for disabled crtcs as well
(excluding bigjoiner slaves of course which have had their state
copied from the master).

I actually already did this once in commit fff13e63a1 ("drm/i915:
Clear most of crtc state when disabling the crtc") but then
commit 19f65a3dbf ("drm/i915: Try to make bigjoiner work in atomic
check") undid it all :(

7d7007686b drm/i915: Remove odd any_ms=true assignment
For some reason we're flagging that we need to run through the
full modeset calculations (any_ms==true -> do cdclk/etc. checks)
if any crtc got initially flagged for a modeset and is not
enabled via the uapi. No idea why this is here since later on
(after all fastset handling) we do full run through the crtcs
and flag any_ms if anything still needs a full modeset. So let's
just throw out this early weirdo.

9bc34b4d0f drm/i915/display/vrr: Reset VRR capable property on a long hpd
With some VRR panels, user can turn VRR ON/OFF on the fly from the panel settings.
When VRR is turned OFF ,sends a long HPD to the driver clearing the Ignore MSA bit
in the DPCD. Currently the driver parses that onevery HPD but fails to reset
the corresponding VRR Capable Connector property.
Hence the userspace still sees this as VRR Capable panel which is incorrect.

Fix this by explicitly resetting the connector property.

v2: Reset vrr capable if status == connector_disconnected
v3: Use i915 and use bool vrr_capable (Jani Nikula)
v4: Move vrr_capable to after update modes call (Jani N)

95ee2a8b4b drm: implement a method to free unused pages
On contiguous allocation, we round up the size
to the *next* power of 2, implement a function
to free the unused pages after the newly allocate block.

v2(Matthew Auld):
  - replace function name 'drm_buddy_free_unused_pages' with
    drm_buddy_block_trim
  - replace input argument name 'actual_size' with 'new_size'
  - add more validation checks for input arguments
  - add overlaps check to avoid needless searching and splitting
  - merged the below patch to see the feature in action
     - add free unused pages support to i915 driver
  - lock drm_buddy_block_trim() function as it calls mark_free/mark_split
    are all globally visible

v3(Matthew Auld):
  - remove trim method error handling as we address the failure case
    at drm_buddy_block_trim() function

v4:
  - in case of trim, at __alloc_range() split_block failure path
    marks the block as free and removes it from the original list,
    potentially also freeing it, to overcome this problem, we turn
    the drm_buddy_block_trim() input node into a temporary node to
    prevent recursively freeing itself, but still retain the
    un-splitting/freeing of the other nodes(Matthew Auld)

  - modify the drm_buddy_block_trim() function return type

v5(Matthew Auld):
  - revert drm_buddy_block_trim() function return type changes in v4
  - modify drm_buddy_block_trim() passing argument n_pages to original_size
    as n_pages has already been rounded up to the next power-of-two and
    passing n_pages results noop

v6:
  - fix warnings reported by kernel test robot <lkp@intel.com>

v7:
  - modify drm_buddy_block_trim() function doc description
  - at drm_buddy_block_trim() handle non-allocated block as
    a serious programmer error
  - fix a typo

476e406302 drm: implement top-down allocation method
Implemented a function which walk through the order list,
compares the offset and returns the maximum offset block,
this method is unpredictable in obtaining the high range
address blocks which depends on allocation and deallocation.
for instance, if driver requests address at a low specific
range, allocator traverses from the root block and splits
the larger blocks until it reaches the specific block and
in the process of splitting, lower orders in the freelist
are occupied with low range address blocks and for the
subsequent TOPDOWN memory request we may return the low
range blocks.To overcome this issue, we may go with the
below approach.

The other approach, sorting each order list entries in
ascending order and compares the last entry of each
order list in the freelist and return the max block.
This creates sorting overhead on every drm_buddy_free()
request and split up of larger blocks for a single page
request.

  - replace uint64_t with u64, which is preferred in the kernel

v4(Matthew Auld):

    actual range allocations
  - keep alloc_range() implementation for end bias allocations

v5(Matthew Auld):
  - modify drm_buddy_alloc() passing argument place->lpfn to lpfn

The VBT DSI video transfer mode field values have been defined in terms
of the VLV MIPI_VIDEO_MODE_FORMAT register. The ICL DSI code maps that
to ICL DSI_TRANS_FUNC_CONF() register. The values are the same, though
the shift is different.

Make a clean break and disassociate the values from each other. Assume
the values can be different, and translate the VBT value to VLV and ICL
register values as needed. Use the existing macros from intel_bios.h.

This will be useful in splitting the DSI register macros to files by DSI

d8a8cf8242 drm/vc4: Use drm_mode_copy()
struct drm_display_mode embeds a list head, so overwriting
the full struct with another one will corrupt the list
(if the destination mode is on a list). Use drm_mode_copy()
instead which explicitly preserves the list head of
the destination mode.

Even if we know the destination mode is not on any list
using drm_mode_copy() seems decent as it sets a good
example. Bad examples of not using it might eventually
get copied into code where preserving the list head
actually matters.

Obviously one case not covered here is when the mode
itself is embedded in a larger structure and the whole
structure is copied. But if we are careful when copying
into modes embedded in structures I think we can be a
little more reassured that bogus list heads haven't been
propagated in.

5e3094cfd9 drm/i915/xehpsdv: Add has_flat_ccs to device info
Platforms of XeHP and beyond support 3D surface (buffer) compression and
various compression formats. This is accomplished by an additional
compression control state (CCS) stored for each surface.

Gen 12 devices(TGL family and DG1) stores compression states in a separate
region of memory. It is managed by user-space and has an associated set of
user-space managed page tables used by hardware for address translation.

In Xe HP and beyond (XEHPSDV, DG2, etc), there is a new feature introduced
i.e Flat CCS. It replaced AUX page tables with a flat indexed region of
device memory for storing compression states.
