Subject: drm/sun4i: Fix sun8i HDMI PHY clock initialization

Current code initializes HDMI PHY clock driver before reset line is
deasserted and clocks enabled. Because of that, initial readout of
clock divider is incorrect (0 instead of 2). This causes any clock
rate with divider 1 (register value 0) to be set incorrectly.

Fix this by moving initialization of HDMI PHY clock driver after reset
line is deasserted and clocks enabled.

Subject: drm/sun4i: sun6i_mipi_dsi: Fix hsync_porch overflow

Loop N1 instruction delay for burst mode devices are computed
based on horizontal sync and porch timing values.

The current driver is using u16 type for computing this hsync_porch
value, which would failed to fit within the u16 type for large sync
and porch timings devices. This would result in hsync_porch overflow
and eventually computed wrong instruction delay value.

Example, timings, where it produces the overflow
{
	.hdisplay       = 1080,
	.hsync_start    = 1080 + 408,
        .hsync_end      = 1080 + 408 + 4,
        .htotal         = 1080 + 408 + 4 + 38,
}

It reproduces the desired delay value 65487 but the correct working
value should be 7.

So, Fix it by computing hsync_porch value separately with u32 type.

Subject: 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.

Subject: drm/i915: Downgrade NEWCLIENT to non-preemptive

Commit 1413b2bc0717 ("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.

Subject: drm/i915: Truly bump ready tasks ahead of busywaits

In commit b7404c7ecb38 ("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):

Subject: 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.

Subject: drm/i915/gvt: emit init breadcrumb for gvt request

"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.

v2: cc to stable kernel

Subject: 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)
v2: update vreg when scanning indirect context for inhibit context for
gen9

Subject: drm/vmwgfx: Fix user space handle equal to zero

User-space handles equal to zero are interpreted as uninitialized or
illegal by some drm systems (most notably kms). This means that a
dumb buffer or surface with a zero user-space handle can never be
used as a kms frame-buffer.

Subject: drm/vmwgfx: Fix compat mode shader operation

In compat mode, we allowed host-backed user-space with guest-backed
kernel / device. In this mode, set shader commands was broken since
no relocations were emitted. Fix this.

Subject: 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.

If SVGA_3D_CMD_DX_SET_SHADER is called with a shader ID

Subject: drm/gma500/cdv: Check vbt config bits when detecting lvds panels

Some machines have an lvds child device in vbt even though a panel is
not attached. To make detection more reliable we now also check the lvds
config bits available in the vbt.

Subject: drm/panfrost: Select devfreq

Currently, there is some logic for the driver to work without devfreq.
However, the driver actually fails to probe if !CONFIG_PM_DEVFREQ.

Fix this by selecting devfreq, and drop the additional checks
for devfreq.

Subject: drm/i915: Maintain consistent documentation subsection ordering

With Sphinx 2.0 (or prior versions with the deprecation warnings fixed) the
docs build fails with:

  Documentation/gpu/i915.rst:403: WARNING: Title level inconsistent:

  Global GTT Fence Handling
  ~~~~~~~~~~~~~~~~~~~~~~~~~

  reST markup error:
  Documentation/gpu/i915.rst:403: (SEVERE/4) Title level inconsistent:

I "fixed" it by changing the subsections in i915.rst, but that didn't seem
like the correct change.  It turns out that a couple of i915 files create
their own subsections in kerneldoc comments using apostrophes as the
heading marker:

  Layout
  ''''''

That breaks the normal subsection marker ordering, and newer Sphinx is
rather more strict about enforcing that ordering.  So fix the offending
comments to make Sphinx happy.

(This is unfortunate, in that kerneldoc comments shouldn't need to be aware
of where they might be included in the heading hierarchy, but I don't see
a better way around it).

Subject: drm/amd/display: Don't load DMCU for Raven 1 (v2)

[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.

v2: Fix ifdef (Alex)

Subject: drm/imx: ipuv3-plane: fix atomic update status query for non-plus
 i.MX6Q

The current buffer check halves the frame rate on non-plus i.MX6Q,
as the IDMAC current buffer pointer is not yet updated when
ipu_plane_atomic_update_pending is called from the EOF irq handler.

The devcoredump needs to operate on a stable state of the MMU while
it is writing the MMU state to the coredump. The missing lock
allowed both the userspace submit, as well as the GPU job finish
paths to mutate the MMU state while a coredump is under way.
