Add vram based cgroup eviction to Xe.
Most hardware with VRAM uses TTM for its management, and can be
similarly trivially enabled.

cgroup resource allocation has to be handled in TTM, so -EAGAIN from
cgroups can be converted into -ENOSPC, and the limitcg can be properly
evicted in ttm code.
When hitting a resource limit through -EAGAIN, the cgroup for which the
limit is hit is also returned. This allows eviction to delete only from
cgroups which are a subgroup of the current cgroup.
The returned CSS is used to determine if eviction is valuable for a
given resource, and allows TTM to only target specific resources to
lower memory usage.

Enable basic 128b/132b SST functionality without compression. Reuse
intel_dp_mtp_tu_compute_config() to figure out the TU after we've
determined we need to use an UHBR rate.
It's slightly complicated as the M/N computation is done in different
places in MST and SST paths, so we need to avoid trashing the values
later for UHBR.
If uncompressed UHBR fails, we drop to compressed non-UHBR, which is
quite likely to fail as well. We still lack 128b/132b SST+DSC.
We need mst_master_transcoder also for 128b/132b SST. Use cpu_transcoder
directly. Enhanced framing is "don't care" for 128b/132b link.

We'll want to distinguish 128b/132b SST and MST modes at state
readout. There's a catch, though. From the hardware perspective,
128b/132b SST and MST programming are pretty much the same. And we can't
really ask the sink at this point.
If we have more than one transcoder in 128b/132b mode associated with
the port, we can safely assume it's MST. But for MST with only a single
stream enabled, we are pretty much out of luck. Let's fall back to
looking at the software state, i.e. intel_dp->is_mst. It should be fine
for the state checker, but for hardware takeover at probe, we'll have to
trust the GOP has only enabled SST.
TODO: Not sure how this *or* our current code handles 128b/132b enabled
by GOP.

The callers of mst_stream_find_vcpi_slots_for_bpp() don't need the
returned slots for anything. On the contrary, they need to jump through
hoops to just distinguish between success and failure. Just return 0
instead of slots from mst_stream_find_vcpi_slots_for_bpp() for success,
and simplify the callers.
There's a pointless ret local variable that we can drop in the process.

The struct drm_dp_mst_topology_mgr *mgr parameter is only used for debug
logging in case the passed in link rate or lane count are zero. There's
no further error checking as such, and the function returns 0.
There should be no case where the parameters are zero. The returned
value is generally used as a divisor, and if we were hitting this, we'd
be seeing division by zero.
Just remove the debug logging altogether, along with the mgr parameter,
so that the function can be used in non-MST contexts without the
topology manager.

Currently, when bandwidth is insufficient for a given mode, we attempt
to use DSC. This is indicated by a debug print, followed by a check for
DSC support.
The debug message states that we are trying DSC, but DSC might not be
supported, which can give an incorrect picture in the logs if we bail
out later.
Correct the order for both DP and DP MST to:
- Check if DSC is required and supported, and return early if DSC is
not supported.
- Print a debug message to indicate that DSC will be tried next.

This code is based on the RDMA and misc cgroup initially, but now
uses page_counter. It uses the same min/low/max semantics as the memory
cgroup as a result.
There's a small mismatch as TTM uses u64, and page_counter long pages.
In practice it's not a problem. 32-bits systems don't really come with
>=4GB cards and as long as we're consistently wrong with units, it's
fine. The device page size may not be in the same units as kernel page
size, and each region might also have a different page size (VRAM vs GART
for example).
The interface is simple:
- Call dmem_cgroup_register_region()
- Use dmem_cgroup_try_charge to check if you can allocate a chunk of memory,
use dmem_cgroup__uncharge when freeing it. This may return an error code,
or -EAGAIN when the cgroup limit is reached. In that case a reference
to the limiting pool is returned.
- The limiting cs can be used as compare function for
dmem_cgroup_state_evict_valuable.
- After having evicted enough, drop reference to limiting cs with
dmem_cgroup_pool_state_put.
This API allows you to limit device resources with cgroups.
You can see the supported cards in /sys/fs/cgroup/dmem.capacity
You need to echo +dmem to cgroup.subtree_control, and then you can
partition device memory.

The Arch Linux glibc package contains a versioned dependency on
"linux-api-headers". If the linux-api-headers package provided by
pacman-pkg does not specify an explicit version this dependency is not
satisfied.
Fix the dependency by providing an explicit version.

Use the helper function to update the connector's information. This
makes sure that HDMI-related events are handled in a generic way.
Currently it is limited to the HDMI state reporting to the sound system.

The vc4_hdmi_connector_detect_ctx() via vc4_hdmi_handle_hotplug()
already reads EDID and propagates it to the drm_connector. Stop
rereading EDID as a part of the .get_modes() callback and just update
the list of modes. This matches the behaviour of the i915 driver.
