8dc39cfca3 drm/vmwgfx: Use the dma scatter-gather iterator to get dma addresses
Use struct sg_dma_page_iter in favour struct of sg_page_iter, which fairly
recently was declared useless for obtaining dma addresses.

With a struct sg_dma_page_iter we can't call sg_page_iter_page() so
when the page is needed, use the same page lookup mechanism as for the
non-sg dma modes instead of calling sg_dma_page_iter.

Note, the fixes tag doesn't really point to a commit introducing a
failure / regression, but rather to a commit that implemented a simple
workaround for this problem.

df2ea3c296 drm/i915/gvt: use cmd to restore in-context mmios to hw for gen9 platform
for restore-inhibit context, hardware will not load in-context mmios
(engine context part) to hardware, but hardware will save the mmio
values in hardware back to context image. So, in order to save correct
values of vGPU back to context image, values of vGPU mmios have to be
loaded into hardware first for restore-inhibit context.

In this patch, the mechanism is applied to all gen9 platform.

The reason excluding gen8 platforms is only because of lacking of testing
on those platforms.

v3: for mocs registers, goto in-context mmios save-restore path for skl
platform as well (weinan li)

"To track whether a request has started on HW, we can emit a breadcrumb at
the beginning of the request and check its timeline's HWSP to see if the
breadcrumb has advanced past the start of this request." It means all the
request which timeline's has_init_breadcrumb is true, then the
emit_init_breadcrumb process must have before emitting the real commands,
otherwise, the scheduler might get a wrong state of this request during
reset. If the request is exactly the guilty one, the scheduler won't
terminate it with the wrong state. To avoid this, do emit_init_breadcrumb
for all the requests from gvt.

55143dc23c drm/amd/display: Don't load DMCU for Raven 1
[WHY]
Some early Raven boards had a bad SBIOS that doesn't play nicely with
the DMCU FW. We thought the issues were fixed by ignoring errors on DMCU
load but that doesn't seem to be the case. We've still seen reports of
users unable to boot their systems at all.

[HOW]
Disable DMCU load on Raven 1. Only load it for Raven 2 and Picasso.

a491cc8e15 drm/i915: Truly bump ready tasks ahead of busywaits
In commit b7404c7ecb ("drm/i915: Bump ready tasks ahead of
busywaits"), I tried cutting a corner in order to not install a signal
for each of our dependencies, and only listened to requests on which we
were intending to busywait. The compromise that was made was that
instead of then being able to promote the request with a full
NOSEMAPHORE like its non-busywaiting brethren, as we had not ensured we
had cleared the semaphore chain, we settled for only using the NEWCLIENT
boost. With an over saturated system with multiple NEWCLIENTS in flight
at any time, this was found to be an inadequate promotion and left us
with a much poorer scheduling order than prior to using semaphores.

The outcome of this patch, is that all requests have NOSEMAPHORE
priority when they have no dependencies and are ready to run and not
busywait, restoring the pre-semaphore ordering on saturated systems.

We can demonstrate the effect of poor scheduling order by oversaturating
the system using gem_wsim on a system with multiple vcs engines
(i.e running the same workloads across more clients than required for
peak throughput, e.g. media_load_balance_17i7.wsim -c4 -b context):

c80274bb58 drm/i915: Downgrade NEWCLIENT to non-preemptive
Commit 1413b2bc07 ("drm/i915: Trim NEWCLIENT boosting") had the
intended consequence of not allowing a sequence of work that merely
crossed into a new engine the privilege to be promoted to NEWCLIENT
status. It also had the unintended consequence of actually making
NEWCLIENT effective on heavily oversubscribed transcode machines and
impacting upon their throughput.

If we consider a client packet composed of (rcsA, rcsB, vcs) and 30 of
those clients, using the NEWCLIENT boost that will be scheduled as

	rcsA x 30, (rcsB, vcs) x 30

where as before it would have been

	(rcsA, rcsB, vcs) x 30

That is with NEWCLIENT only boosting the first request of each client,
we would execute all rcsA requests prior to running on the vcs engines;
acruing a lot of dead time as compared to the previous case where the
vcs engine would be started in parallel to processing the second client.

The previous patch has the effect of delaying submission until it is
required by a third party (either the user with an explicit wait, or by
another client/engine). We reduce the NEWCLIENT bump to a mere WAIT,
which has the effect of removing its preemptive grant and reducing it to
the same level as any other user interaction -- that it will not be
promoted above the interengine dependencies, and so preventing NEWCLIENTS
from starving other engines. This a large nerf to the rrul properties of
the current NEWCLIENT, but it still does give prioritised submission to
new requests from light workloads.

9981927cc9 drm/i915: Bump signaler priority on adding a waiter
The handling of the no-preemption priority level imposes the restriction
that we need to maintain the implied ordering even though preemption is
disabled. Otherwise we may end up with an AB-BA deadlock across multiple
engine due to a real preemption event reordering the no-preemption
WAITs. To resolve this issue we currently promote all requests to WAIT
on unsubmission, however this interferes with the timeslicing
requirement that we do not apply any implicit promotion that will defeat
the round-robin timeslice list. (If we automatically promote the active
request it will go back to the head of the queue and not the tail!)

So we need implicit promotion to prevent reordering around semaphores
where we are not allowed to preempt, and we must avoid implicit
promotion on unsubmission. So instead of at unsubmit, if we apply that
implicit promotion on adding the dependency, we avoid the semaphore
deadlock and we also reduce the gains made by the promotion for user
space waiting. Furthermore, by keeping the earlier dependencies at a
higher level, we reduce the search space for timeslicing without
altering runtime scheduling too badly (no dependencies at all will be
assigned a higher priority for rrul).

v2: Limit the bump to external edges (as originally intended) i.e.
between contexts and out to the user.

Pull perf tooling updates from Ingo Molnar:
 "perf.data:

   - Streaming compression of perf ring buffer into
     PERF_RECORD_COMPRESSED user space records, resulting in ~3-5x
     perf.data file size reduction on variety of tested workloads what
     saves storage space on larger server systems where perf.data size
     can easily reach several tens or even hundreds of GiBs, especially
     when profiling with DWARF-based stacks and tracing of context
     switches.

  perf record:

   - Improve -user-regs/intr-regs suggestions to overcome errors

  perf annotate:

   - Remove hist__account_cycles() from callback, speeding up branch
     processing (perf record -b)

  perf stat:

   - Add a 'percore' event qualifier, e.g.: -e
     cpu/event=0,umask=0x3,percore=1/, that sums up the event counts for
     both hardware threads in a core.

     We can already do this with --per-core, but it's often useful to do
     this together with other metrics that are collected per hardware
     thread.

     I.e. now its possible to do this per-event, and have it mixed with
     other events not aggregated by core.

  arm64:

   - Map Brahma-B53 CPUID to cortex-a53 events.

   - Add Cortex-A57 and Cortex-A72 events.

  csky:

   - Add DWARF register mappings for libdw, allowing --call-graph=dwarf
     to work on the C-SKY arch.

  x86:

   - Add support for recording and printing XMM registers, available,
     for instance, on Icelake.

   - Add uncore_upi (Intel's "Ultra Path Interconnect" events) JSON
     support. UPI replaced the Intel QuickPath Interconnect (QPI) in
     Xeon Skylake-SP.

  Intel PT:

   - Fix instructions sampling rate.

   - Timestamp fixes.

   - Improve exported-sql-viewer GUI, allowing, for instance, to
     copy'n'paste the trees, useful for e-mailing"
