Not sure what the point of this fbc->possible_frontbuffer_bits is.
And especially don't see why it's returning all the bits when
fbc is not even enabled. So let's just get rid of this and only
say we are interested in the plane's frontbuffer bits when fbc
is actually enabled.

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)
Remove the redundant comment (Jan N)
v5: Fixes the regression on older platforms by resetting the VRR
only if HAS_VRR
v6: Remove the checks from driver, add in drm core before
setting VRR prop (Ville)
v7: Move VRR set/reset to set/unset_edid (Ville)

Add support for the DG2 specific render compression with clear color
framebuffer format.
DG2 onwards discrete gfx has support for new flat CCS mapping,
which brings in display feature in to avoid Aux walk for compressed
surface. This support build on top of Flat CCS support added in XEHPSDV.
FLAT CCS surface base address should be 64k aligned,
Compressed displayable surfaces must use tile4 format.

In addition to the fp_timing,dvo_timing,panel_pnp_id tables
there also exists a panel_name table. Unlike the others this
is just one offset+table_size even though there are still 16
actual panel_names in the data block.
The panel_name table made its first appearance somewhere
around VBT version 156-163. The exact version is not known.
But we don't need to know that since we can just check whether
the pointers block has enough room for it or not.

Currently get_lvds_fp_timing() still returns a pointer to the original
data block rather than our copy. Let's convert the data pointer offsets
to be relative to the data block rather than the whole BDB. With that

Make a copy of each VBT data block with a guaranteed minimum
size. The extra (if any) will just be left zeroed.
This means we don't have to worry about going out of bounds
when accessing any of the structure members. Otherwise that
could easliy happen if we simply get the version check wrong,
or if the VBT is broken/malicious.

We skip the initialization of PHY A, but later we try to find out what
is the phy for that power well and dereference dig_port, which is NULL.
Failing the PHY calibration could be left as a warning or error, like it
was before commit b4eb76d82a0e ("drm/i915/dg2: Skip output init on PHY
calibration failure"). However that often fails for outputs not being
used, which would make the warning/error appear on systems that have no
visible issues. Anyway, there is still a need to fix those failures,
but that is left for later.

If ret isn't zero, it is almost for sure ETIMEDOUT, because
we use it in wait_for macro which does continuous retries
until timeout is reached. If we still ran out of time and
retries, we most likely would be interested in getting status,
to understand what was the actual error propagated from PCode,
rather than to find out that we had a time out, which is anyway
quite obvious, if the function fails.

Currently skl_pcode_try_request function doesn't
properly handle return value it gets from
snb_pcode_rw, but treats status != 0 as success,
returning true, which basically doesn't allow
to use retry/timeout mechanisms if PCode happens
to be busy and returns EGAIN or some other status
code not equal to 0.
We saw this on real hw and also tried simulating this
by always returning -EAGAIN from snb_pcode_rw for 6 times, which
currently will just result in false success, while it should
have tried until timeout is reached:
[ 22.357729] i915 0000:00:02.0: [drm:intel_cdclk_dump_config [i915]] Changing CDCLK to
307200 kHz, VCO 614400 kHz, ref 38400 kHz, bypass 19200 kHz, voltage level 0
[ 22.357831] i915 0000:00:02.0: [drm:__snb_pcode_rw [i915]] Returning EAGAIN retry 1
[ 22.357892] i915 0000:00:02.0: [drm:skl_pcode_request [i915]] Success, exiting
[ 22.357936] i915 0000:00:02.0: [drm] ERROR Failed to inform PCU about cdclk change (err -11, freq 307200)
We see en error because higher level api, still notices that status was wrong,
however we still did try only once.
We fix it by requiring _both_ the status to be 0 and
request/reply match for success(true) and function
should return failure(false) if either status turns
out to be EAGAIN, EBUSY or whatever or reply/request
masks do not match.
So now we see this in the logs:

The intent of the version check in the mmap ioctl was to maintain
support for existing platforms (i.e., ADL/RPL and earlier), but drop
support on all future igpu platforms. As we've seen on the dgpu side,
the hardware teams are using a more fine-grained numbering system for IP
version numbers these days, so it's possible the version number
associated with our next igpu could be some form of "12.xx" rather than
13 or higher. Comparing against the full ver.release number will ensure
the intent of the check is maintained no matter what numbering the
hardware teams settle on.

All of CI is just failing with the following, which prevents loading of
the module:
i915 0000:03:00.0: [drm] *ERROR* Scratch setup failed
Best guess is that this comes from the pin_map() for the scratch page,
which does an i915_gem_object_wait_moving_fence() somewhere. It looks
like this now calls into dma_resv_wait_timeout() which can return the
remaining timeout, leading to the caller thinking this is an error.

Freq caps (i.e. RP0, RP1 and RPn frequencies) are read from HW. However the
formats (bit positions, widths, registers and units) of these vary for
different generations with even more variations arriving in the future. In
order not to have to do identical computation for these caps in multiple
places, here we centralize the computation of these caps. This makes the
code cleaner and also more extensible for the future.

Add an usage for kernel submissions. Waiting for those are mandatory for
dynamic DMA-bufs.
As a precaution this patch also changes all occurrences where fences are
added as part of memory management in TTM, VMWGFX and i915 to use the
new value because it now becomes possible for drivers to ignore fences
with the WRITE usage.
v2: use "must" in documentation, fix whitespaces
v3: separate out some driver changes and better document why some
changes should still be part of this patch.

This change adds the dma_resv_usage enum and allows us to specify why a
dma_resv object is queried for its containing fences.
Additional to that a dma_resv_usage_rw() helper function is added to aid
retrieving the fences for a read or write userspace submission.
This is then deployed to the different query functions of the dma_resv
object and all of their users. When the write paratermer was previously
true we now use DMA_RESV_USAGE_WRITE and DMA_RESV_USAGE_READ otherwise.
v2: add KERNEL/OTHER in separate patch

Since gen6 we use FPGA_DBG register to detect unclaimed MMIO registers.
This register is in the display engine IP and can only ever detect
unclaimed accesses to registers in this area. However sometimes there
are reports of this triggering for registers in other areas, which
should not be possible.
Right now we always warn after the read/write of registers going through
unclaimed_reg_debug(). However places using __raw_uncore_* may be
triggering the unclaimed access and those being later accounted to a
different register. Let's warn both before and after the read/write
with a slightly different message, so it's clear if the register
reported in the warning is actually the culprit.
Commit dda960335e02 ("drm/i915: Just clear the mmiodebug before a
register access") attempted to solve the same issue by removing the
warning when if FPGA_DBG flags before the mmio read/write. However, it
doesn't solve it completely as FPGA_DBG may remain set when reading
registers outside display. So in the end the check after the mmio
read/write triggers the warning pointing to the wrong register.

Some functions defined in the intel-gtt module are used in several
areas, but is only supported on x86 platforms.
By separating these calls and their static underlying functions to
another area, we are able to compile out these functions for
non-x86 builds and provide stubs for the non-x86 implementations.
In addition to the problematic calls, we are moving the gmch-related
functions to the new area.

Accessing the DDI_BUF_CTL register without the port's DDI clock being
enabled (to set/clear the TypeC PHY ownership for the port) can lead to
a corrupted value read during any i915 register access right after the
DDI clock is enabled.
The root cause is the way clock synchronization works for this register,
controlled by the CHICKEN_DCPR_1 DDI_CLOCK_REG_ACCESS flag. Correctly
this flag should be cleared on ADLP (see the Bspec link below), however
after bootup the flag is set.
One easily reproducible issue is an unclaimed register access of the
PWR_WELL_CTL_DDI2 register, programmed right after DDI clock enabling to
enable the port's DDI_IO power well (see the HSDES, VLK links below).
With the correct setting above this problem can't be reproduced.

Instead of exit PSR when a frontbuffer invalidation happens, we can
enable the PSR2 selective fetch continuous full frame, that will keep
the panel updated like PSR was disabled but without keeping PSR active.
So as soon as the frontbuffer flush happens we can disable the
continuous full frame and start to do selective fetches much quicker
than the path that would enable PSR, that will wait a few frames
to actually activate PSR.
Also this approach has proven to fix some glitches found in Alderlake-P
when there are a lot of invalidations happening together with page
flips.
Some may ask why it is writing to CURSURFLIVE(), it is because
that is the way that hardware team provided us to poke display to
handle PSR updates, and it is being used since display 9.

Frontbuffer rendering and page flips can race with each other
and this can potentialy cause issues with PSR2 selective fetch.
And because pipe/crtc updates are time sentive we can't grab the
PSR lock after intel_pipe_update_start() and before
intel_pipe_update_end().
So here adding the lock and unlock functions and calls, the
proper PSR2 selective fetch handling will come in a separated patch.

"SF Partial Frame Enable" also on full update") and also setting
partial frame enable when psr_force_hw_tracking_exit() is called.
Also as PSR2_MAN_TRK_CTL is a double buffered registers do a RMW
is not a good idea so here also setting the man_trk_ctl_enable_bit()
that is required in TGL and only doing a register write.

The request to aqquire gem resources is failing for DSB in rare
scenario where it is busy and the register programming will be done
through mmio fallback path.
DSB has extra advantage of faster register programming which may
go away through mmio path. Adding wait for gem resource also may
not be right as anyways losing time.

for printing debug info during dsb buffer preparation.

Our YCbCr output is always supposed to be limited range BT.709.
That's what we send with native HDMI. The conn_state->colorspace

the generated output in any way. If we want a way to do that then
we need a new proprty for it.
Make it so that the RGB->YCbCr conversion when performed by the
DPF will match the BT.709 we would transmit with native HDMI.

Extend that support for DP as well.
With all the HDMI DFP TMDS clock handling sorted out this

output is possible, and if not we try YCbCr 4:2:0 instead.

Rework the HDMI DFP TMDS clock checks to also check at 8bpc.
Previously we only checked the deep color cases. But I suppose
a sink could potentially declare "4:2:0 also" modes that only
actually fit within its own limits when using 4:2:0. Even if
that is too nuts to be real there is no real harm in running
through the full checks for everything.
