I have not yet sent the dGPU topology code because it depends on a patch

upstreamed we can continue with the rest of the dGPU code.

Looking at a CI failure with an ominous line of

if someone had scribbled over the HWSP. So include the HWSP in the

We should only attempt to remove requests from the execution queue that
are on the execution queue. These are the requests that have been
assigned a global_seqno, so we can assert that we only attempt to remove
requests with a nonzero global_seqno. Afterwards we assert that we
remove them in order, i.e. the global_seqno matches the engine's seqno,
but that leaves a small loophole for an unattached request on an unused
engine.

We can then make the same assertion on queuing the request to the
execution engine, it must have a zero global_seqno or else we are queuing
the same request twice.

We have plenty of global registers and whatnot programmed without
any further locking by the modeset code. Currently non-bocking
modesets are allowed to execute in parallel which could corrupt
said registers.

To avoid the problem let's run all non-blocking modesets on an
ordered workqueue. We still put page flips etc. to system_unbound_wq
allowing page flips on one pipe to execute in parallel with page flips
or a modeset on a another pipe (assuming no known state is shared
between them, at which point they would have been added to the same
atomic commit and serialized that way).

Blocking modesets are already serialized with each other by
connection_mutex, and thus are safe. To serialize them with
non-blocking modesets we just flush the workqueue before executing
blocking modesets.

Gen9+ need to disable GMBUS clock gating when doing multi part
transfers. Otherwise clock gating will kick in when GMBUS is in
the WAIT state and presumably that will corrupt the transfer.
This is documented as Display WA #0868.

Apparently older hardware doesn't allow clock gating in the WAIT
state and thus are unaffected by this problem.

Our QA reported a problem caused by movntdqa instructions. Currently,
the KVM hypervisor doesn't support VEX-prefix instructions emulation.
If users passthrough a GPU to guest with vfio option 'x-no-mmap=on',
then all access to the BARs will be trapped and emulated. The KVM
hypervisor would raise an inertal error to qemu which cause the guest
killed. (Since 'movntdqa' ins is not supported.)

This patch try not to enable movntdqa optimization if the driver is
running in hypervisor guest.

We don't need any active planes during load detection, so just disable
them all. This saves us from having to come up with a suitable
framebuffer. And we also avoid leaving sprite/cursor planes on and
potentially presenting them at a peculiar location during the load
detection.

Changes since v1 (Maarten):
- Add missing call to add_all_affected_planes.

Current code advertises (on the modifiers blob property) support for CCS
modifier for pipe C on GLK, only to reject it later when validating the
request before the atomic commit.

This fixes the tests igt@kms_ccs@pipe-c-*, which should skip on GLK for
pipe C (see bug 104096).
