In case of Gen12.50 video and compute engines, TLB_INV registers are
masked - to modify one bit, corresponding bit in upper half of the register
must be enabled, otherwise nothing happens.

Post_disable was sending the D-PHY sequence to put any device
into ULPS suspend mode, and then cutting power to the DSI block.
The power-on reset state of the DSI block is for DSI to be in
an operational state, not ULPS, so it then never sent the sequence
for exiting ULPS. Any attached device that didn't have an external
reset therefore remained in ULPS / standby, and didn't function.
Use of ULPS isn't well specified in DRM, therefore remove entering
it to avoid the above situation.

Remove the encoder functions, and create a bridge attached to
this dumb encoder which implements the same functionality.
As a bridge has state which an encoder doesn't, we need to
add the state management functions as well.
As there is no bridge atomic_mode_set, move the initialisation
code that was in mode_set into _pre_enable.
The code to actually enable and disable sending video are split
from the general control into _enable and _disable.

Splitting the bridge chain fails for atomic bridges as the
framework can't add the relevant state in
drm_atomic_add_encoder_bridges.
The chain was split because we needed to power up before
calling pre_enable, but that is now done in mode_set, and will
move into the framework.

Breaking the bridge chain does not work for atomic bridges/panels
and generally causes issues.
We need to initialise the DSI host before the bridge pre_enables
are called, so move that to encoder_mode_set in the same way that
dw-mipi-dsi does.

This reverts commit f9d00a4a8dc8fff951c97b3213f90d6bc7a72175.
This causes problem for KFD because when we overcommit we accidentially
bind the BO to GTT for moving it into VRAM. We also need to make sure

Remove the "domain" argument to amdgpu_bo_create_kernel_at() since this
function takes an "offset" argument which is the offset off of VRAM, and as
such allocation always takes place in VRAM. Thus, the "domain" argument is

It seems we can have one or more framebuffers that are still pinned when
suspending lmem, in such a case we end up creating a shmem backup
object, instead of evicting the object directly, but this will skip
copying the CCS aux state, since we don't allocate the extra storage for
the CCS pages as part of the ttm_tt construction. Since we can already
deal with pinned objects just fine, it doesn't seem too nasty to just
extend to support dealing with the CCS aux state, if the object is a
pinned framebuffer. This fixes display corruption (like in gnome-shell)
seen on DG2 when returning from suspend.

git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd
Pull iommufd implementation from Jason Gunthorpe:
"iommufd is the user API to control the IOMMU subsystem as it relates
to managing IO page tables that point at user space memory.
It takes over from drivers/vfio/vfio_iommu_type1.c (aka the VFIO
container) which is the VFIO specific interface for a similar idea.
We see a broad need for extended features, some being highly IOMMU
device specific:
- Binding iommu_domain's to PASID/SSID
- Userspace IO page tables, for ARM, x86 and S390
- Kernel bypassed invalidation of user page tables
- Re-use of the KVM page table in the IOMMU
- Dirty page tracking in the IOMMU
- Runtime Increase/Decrease of IOPTE size
- PRI support with faults resolved in userspace
Many of these HW features exist to support VM use cases - for instance
the combination of PASID, PRI and Userspace IO Page Tables allows an
implementation of DMA Shared Virtual Addressing (vSVA) within a guest.
Dirty tracking enables VM live migration with SRIOV devices and PASID
support allow creating "scalable IOV" devices, among other things.
As these features are fundamental to a VM platform they need to be
uniformly exposed to all the driver families that do DMA into VMs,
which is currently VFIO and VDPA"

If the ring is nearly full when calling into emit_pte(), we might
incorrectly trample the reserved_space when constructing the packet to
emit the PTEs. This then triggers the GEM_BUG_ON(rq->reserved_space >
ring->space) when later submitting the request, since the request itself
doesn't have enough space left in the ring to emit things like
workarounds, breadcrumbs etc.

Bspecs has updated recently to remove the restriction to disable
DDI/Transcoder before setting PHY test pattern. This update is to
address PHY compliance test failures observed on a port with LTTPR.
The issue is that when Transc. is disabled, the main link signals fed
to LTTPR will be dropped invalidating link training, which will affect
the quality of the phy test pattern when the transcoder is enabled again.

Despite what I claimed in commit c3c5dc1d9224
("drm/i915/audio: Do the vblank waits") the vblank
interrupts are in fact not enabled yet when we do the
audio enable sequence on VLV/CHV (all other platforms are
fine).
Reorder the enable sequence on VLV/CHV to match that of the
other platforms so that the audio enable happens after the
pipe has been enabled.

Fix intel_dp_dsc_compute_config, previously timeslots parameter
was used in fact not as a timeslots, but more like a ratio
timeslots/64, which of course didn't have any effect for SST DSC,
but causes now issues for MST DSC.
Secondly we need to calculate pipe_bpp using intel_dp_dsc_compute_bpp
only for SST DSC case, while for MST case it has been calculated
earlier already with intel_dp_dsc_mst_compute_link_config.
Third we also were wrongly determining sink min bpp/max bpp, those
limites should be intersected with our limits to find common
acceptable bpp's, plus on top of that we should align those with
VESA bpps and only then calculate required timeslots amount.
Some MST hubs started to work only after third change was made.
v2: Make kernel test robot happy(claimed there was unitialzed use,
while there is none)

We might to use that function separately from intel_dp_dsc_compute_config
for DP DSC over MST case, because allocating bandwidth in that
case can be a bit more tricky. So in order to avoid code copy-pasta
lets extract this to separate function and reuse it for both SST
and MST cases.
v2: Removed multiple blank lines

Whenever we are not able to get enough timeslots
for required PBN, let's try to allocate those
using DSC, just same way as we do for SST.
v2: Removed intel_dp_mst_dsc_compute_config and refactored
intel_dp_dsc_compute_config to support timeslots as a
parameter(Ville Syrjälä)
v3: - Rebased
- Added a debug to see that we at least try reserving
VCPI slots using DSC, because currently its not visible
from the logs, thus making debugging more tricky.
- Moved timeslots to numerator, where it should be.
v4: - Call drm_dp_mst_atomic_check already during link
config computation, because we need to know already
by this moment if uncompressed amount of VCPI slots
needed can fit, otherwise we need to use DSC.
(thanks to Vinod Govindapillai for pointing this out)
v5: - Put pipe_config->bigjoiner_pipes back to original
condition in intel_dp_dsc_compute_config
(don't remember when I lost it)
v6: - Removed unnecessary drm_dp_mst_atomic_check as it is
now always called in a newly introduced

We currently always exit that bpp loop because
drm_dp_atomic_find_vcpi_slots doesn't care if we actually
can fit those or not.
I think that wasn't the initial intention here, especially when
we keep trying with lower bpps, we are supposed to keep trying
until we actually find some _working_ configuration, which isn't the
case here.
So added that drm_dp_mst_check here, so that we can make sure
that try all the bpps before we fail.

We could use the dsb to load the LUT in any gamma mode, not just
when using the multi-segment mode. So replace the direct mmio
on all ilk+ paths with the wrapper.
There are a few functions (ilk_load_lut_10(), ivb_load_lut_10())
that would never be used on a platform with dsb so we could
skip those, but probably better to keep all this 100% consistent
to avoid people getting confused and copy pasting the wrong thing
when adding a new gamma mode.
The gmch stuff I left with direct mmio since those are fairly
distinct and shouldn't cause too much confusion. Although
I've also pondered about converting everything over to dsb
command buffers and just executing it on the CPU when the
real hw is not available. But dunno if that would actually
be a good idea or not...

The DSB has problem loading the LUTs at the moment. Some
of that is due to the palette anti collision logic, some
due to what seem real hw issues. Disable it the whole
thing locally in the color management code for now.
Note that we currently have this weird situation where on
adl+ we load parts of the LUT with DSB and parts with mmio.
That is due to the fact that only some parts of the LUT code
are using the DSB register write functions (ivb_load_lut_ext*()),
while the rest is using pure mmio (bdw_load_lut_10()). So now
we'll go back to pure mmio temporarily, until the DSB issues
get fixed (at which point we should be going for pure DSB).

We could have many different uses for the DSB(s) during a
single commit, so the current approach of passing the whole
crtc_state to the DSB functions is far too high level. Lower
the abstraction a little bit so each DSB user can decide where
to stick the command buffer/etc.

Since the color management code is the only user of the DSB
at the moment move the DSB prepare/cleanup there too. The
code has to anyway make decisions on whether to use the DSB
or not (and how to use it). Also we'll need a place where we
actually generate the DSB command buffer ahead of time rather
than the current situation where it gets generated too late
during the mmio programming of the hardware.
