Liu Ying d7868cb7ac gpu: ipu-v3: ipu-dmfc: Use static DMFC FIFO allocation mechanism
For all video modes we support currently, we always get 2 slots for
a plane by using the current existing dynamic DMFC FIFO allocation
mechanism.  So, let's change to use the static one to simplify the
code.  This also makes it easier to implement the atomic mode setting
as we don't need to handle allocation failure cases then.

Liu Ying 08a8901882 drm/imx: ipuv3 plane: Check different types of plane separately
The IPUv3 primary plane doesn't support partial off screen.
So, this patch separates plane check logics for primary plane and overlay
plane and adds more limitations on the primary plane.

Chris Wilson 396f5d62d1 drm: Restore double clflush on the last partial cacheline
This effectively reverts

commit afcd950caf
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Wed Jun 10 15:58:01 2015 +0100

    drm: Avoid the double clflush on the last cache line in drm_clflush_virt_range()

as we have observed issues with serialisation of the clflush operations
on Baytrail+ Atoms with partial updates. Applying the double flush on the
last cacheline forces that clflush to be ordered with respect to the
previous clflush, and the mfence then protects against prefetches crossing
the clflush boundary.

The same issue can be demonstrated in userspace with igt/gem_exec_flush.

Fixes: afcd950caf (drm: Avoid the double clflush on the last cache...)

Bhaktipriya Shridhar 7b2d16f55c drm/qxl: Remove deprecated create_singlethread_workqueue
System workqueues have been able to handle high level of concurrency
for a long time now and there's no reason to use dedicated workqueues
just to gain concurrency. Since the workqueue in the QXL graphics device
driver is involved in freeing and processing the release ring
(workitem &qdev->gc_workqxl, maps to gc_work which calls
qxl_garbage_collect) and is not being used on a memory reclaim path,
dedicated gc_queue has been replaced with the use of system_wq.

Unlike a dedicated per-cpu workqueue created with create_workqueue(),
system_wq allows multiple work items to overlap executions even on
the same CPU; however, a per-cpu workqueue doesn't have any CPU
locality or global ordering guarantees unless the target CPU is
explicitly specified and thus the increase of local concurrency
shouldn't make any difference.

flush_work() has been called in qxl_device_fini() to ensure that there
are no pending tasks while disconnecting the driver.

This is a cleanup spotted while working on other changes.

(The way it was previously handled could also theoretically result in
drm_queue_vblank_event unnecessarily bumping vblwait->request.sequence,

Mario Kleiner 1bf59f1dcb drm/vc4: Implement precise vblank timestamping.
Precise vblank timestamping is implemented via the
usual scanout position based method. On VC4 the
pixelvalves PV do not have a scanout position
register. Only the hardware video scaler HVS has a
similar register which describes which scanline for
the output is currently composited and stored in the
HVS fifo for later consumption by the PV.

This causes a problem in that the HVS runs at a much
faster clock (system clock / audio gate) than the PV
which runs at video mode dot clock, so the unless the
fifo between HVS and PV is full, the HVS will progress
faster in its observable read line position than video
scan rate, so the HVS position reading can't be directly
translated into a scanout position for timestamp correction.

Additionally when the PV is in vblank, it doesn't consume
from the fifo, so the fifo gets full very quickly and then
the HVS stops compositing until the PV enters active scanout
and starts consuming scanlines from the fifo again, making
new space for the HVS to composite.

Therefore a simple translation of HVS read position into
elapsed time since (or to) start of active scanout does
not work, but for the most interesting cases we can still
get useful and sufficiently accurate results:

1. The PV enters active scanout of a new frame with the
   fifo of the HVS completely full, and the HVS can refill
   any fifo line which gets consumed and thereby freed up by
   the PV during active scanout very quickly. Therefore the
   PV and HVS work effectively in lock-step during active
   scanout with the fifo never having more than 1 scanline
   freed up by the PV before it gets refilled. The PV's
   real scanout position is therefore trailing the HVS
   compositing position as scanoutpos = hvspos - fifosize
   and we can get the true scanoutpos as HVS readpos minus
   fifo size, so precise timestamping works while in active
   scanout, except for the last few scanlines of the frame,
   when the HVS reaches end of frame, stops compositing and
   the PV catches up and drains the fifo. This special case
   would only introduce minor errors though.

2. If we are in vblank, then we can only guess something
   reasonable. If called from vblank irq, we assume the irq is
   usually dispatched with minimum delay, so we can take a
   timestamp taken at entry into the vblank irq handler as a
   baseline and then add a full vblank duration until the
   guessed start of active scanout. As irq dispatch is usually
   pretty low latency this works with relatively low jitter and
   good results.

   If we aren't called from vblank then we could be anywhere
   within the vblank interval, so we return a neutral result,
   simply the current system timestamp, and hope for the best.

Measurement shows the generated timestamps to be rather precise,
and at least never off more than 1 vblank duration worst-case.

Limitations: Doesn't work well yet for interlaced video modes,
             therefore disabled in interlaced mode for now.

v2: Use the DISPBASE registers to determine the FIFO size (changes
    by anholt)

One of the numerous VT-d workarounds we require is that the display
hardware reads past the end of the buffer triggering VT-d faults. This
is acknowledged in the code as being safe "since we fill the unused
portions of the GGTT with the scratch page". Alas, that is no longer
always true and so we trigger DMAR read faults.

Skylake also requires another workaround to avoid mixing VT-d and
unpopulated PTE, and so there we also need to ensure we fill unused

Same problem as with the VM page tables. The user fence address must be

Lyude b636a1b3d6 drm/amdgpu: Poll for both connect/disconnect on analog connectors
DRM_CONNECTOR_POLL_CONNECT only enables polling for connections, not
disconnections. Because of this, we end up losing hotplug polling for
analog connectors once they get connected.

Easy way to reproduce:
 - Grab a machine with an AMD GPU and a VGA port
 - Plug a monitor into the VGA port, wait for it to update the connector
   from disconnected to connected
 - Disconnect the monitor on VGA, a hotplug event is never sent for the
   removal of the connector.

Originally, only using DRM_CONNECTOR_POLL_CONNECT might have been a good
idea since doing VGA polling can sometimes result in having to mess with
the DAC voltages to figure out whether or not there's actually something
there since VGA doesn't have HPD. Doing this would have the potential of
showing visible artifacts on the screen every time we ran a poll while a
VGA display was connected. Luckily, amdgpu_vga_detect() only resorts to
this sort of polling if the poll is forced, and DRM's polling helper
doesn't force it's polls.

Additionally, this removes some assignments to connector->polled that
weren't actually doing anything.

Arindam Nath 505bc983bf drm/amd/powerplay: make sure VCE is disabled by default
This patch is a port of similar patch for amdgpu
when PP is disabled. Since the code flow is little
different when PP is enabled, we need to make sure
the patch is applied for PP enabled path as well.

With the current code, when we boot with the amdgpu
driver enabled and loaded, the VCE also automatically
remains enabled since bootup. This can be verified from
the output of amdgpu_pm_info. It does not matter whether
we boot into command line directly or into X, the VCE
stays enabled the entire time.

before accessing the BO with the CPU again.
