Pull IOMMU updates from Joerg Roedel:
- support for interrupt virtualization in the AMD IOMMU driver. These
patches were shared with the KVM tree and are already merged through
that tree.

some changes outside of the IOMMU code, but these are acked by the
respective maintainers.

If we run out of enough aperture space to fit the entire object, we
fallback to trying to insert a single page. However, if that also fails,
we currently fail to userspace with an unexpected ENOSPC. (ENOSPC means
to userspace that their batch could not be fitted within the GTT.) Prior
to commit e8cb909ac3ab ("drm/i915: Fallback to single page GTT
mmappings for relocations") the approach is to fallback to using the
slow CPU relocation path in case of iomapping failure, and that is the
behaviour we need to restore.

In order not to trigger hangcheck on a idle-but-waiting engine, we need
to distinguish between the pending request queue and the actual
execution queue. This is done later in "drm/i915: Enable multiple
timelines" but for now we need a temporary fix to prevent blaming the
wrong engine for a GPU hang.
(Note that this causes a temporary subtle change in how we decide when
to allow a waitboost to be re-awarded back to the waiter, the temporary
effect is that if the wait is upon the most current execution the wait
is given for free, instead of checking to see if the client stalled
itself. This will be repaired in "drm/i915: Enable multiple timelines".)

We can't rely on connector->status in the detect() hook if the long hpd
was already handled by the dig_port_work as that won't update
connector->status. Thus we have to defer the long hpd handling entirely
until the hotplug work runs to avoid the double long hpd handling
the "detect_done" flag is trying to prevent.
We'll start to depend on connector->status being up to date in a
following patch.

On Braswell, at least, we observe that the context image is written in
multiple phases. The first phase is to clear the register state, and
subsequently rewrite it. A GPU reset at the right moment can interrupt
the context update leaving it corrupt, and our update of the RING_HEAD
is not sufficient to restart the engine afterwards. To recover, we need
to reset the registers back to their original values. The context state
is lost. What we need is a better mechanism to serialise the reset with
pending flushes from the GPU.

When we enable the per-register access mmiodebug, it is to detect which
access is illegal. Reporting on earlier untraced access outside of the

We were previously adding all the planes owned by the CRTC even when
the ddb partitioning didn't change for them. As a consequence, a lot
of functions were being called when we were just moving the cursor
around the screen, such as skylake_update_primary_plane().
This was causing flickering on the primary plane when moving the
cursor. I'm not 100% sure which operation caused the flickering, but
we were writing to a lot of registers, so it could be any of these
writes. With this patch, just moving the mouse won't add the primary
plane to the commit since it won't trigger a change in DDB
partitioning.

DPLL_SDVO_HIGH_SPEED must be set for SDVO/HDMI/DP, but nowhere is it
forbidden to set it for LVDS/CRT as well. So let's also set it on
CRT to make it possible to share the DPLL between HDMI and CRT.
What that bit apparently does is enable the x5 clock to the port,
which then pumps out the bits on both edges of the clock. The DAC
doesn't need that clock since it's not pumping out bits, but I don't
think it hurts to have the DPLL output that clock anyway.
This is fairly important on IVB since it has only two DPLLs with three
pipes. So trying to drive three or more PCH ports with three pipes
is only possible when at least one of the DPLLs gets shared between
two of the pipes.
SNB doesn't really need to do this since it has only two pipes. It could
be done to avoid enabling the second DPLL at all in certain cases, but
I'm not sure that's such a huge win. So let's not do it for SNB, at
least for now. On ILK it never makes sense as the DPLLs can't be shared.
v2: Just always enable the high speed clock to keep things simple (Daniel)

Again, this should only affect the Y tiling cases.
It looks like the relevant code was introduced in 0fda65680e92, but
there's always the possibility that it matched our specification when
it was introduced, and then the specification changed while the code
stayed the same. So we can't really say this was a regression, but
let's try to add a "Fixes" tag anyway to help backporting.
v2: Try to add a "Fixes" tag (Maarten).

The confusing thing is that plane_blocks_per_line is listed as part of
the method 2 calculation but is also used for other things. We
calculated it in two different places and different ways: one inside
skl_wm_method2() and the other inside skl_compute_plane_wm(). The
skl_wm_method2() implementation is the one that matches the
specification.
With this patch we fix the skl_compute_plane_wm() calculation and just
pass it as a parameter to skl_wm_method2(). We also take care to not
modify the value of plane_bytes_per_line since we're going to rely on
it having a correct value in later patches.
This should affect the watermarks for Linear and Y-tiled.
From my analysis, it looks like the two plane_blocks_per_line
variables got out of sync on 0fda65680e92, but we can't really say
that commit was a regression, it looks like just an incomplete fix.
There's always the possibility that 0fda65680e92 matched our
specification at that time, and then later the specification changed.
v2: Try to add a "Fixes" tag (Maarten).

During watermarks calculations, this value is used in 3 different
places. Only one of them was not using a hardcoded 4. Move the code up
so everybody can benefit from the actual value.
This should only help on situations with Y tiling + 90/270 rotation +
1 or 2 bpp or NV12.

Bspec says:
"The mailbox response data may not account for memory read latency.
If the mailbox response data for level 0 is 0us, add 2 microseconds
to the result for each valid level."
This means we should only do the +2 in case wm[0] == 0, not always.
So split the sanitizing implementation from the WA implementation and
fix the WA implementation.

And use it to move knowledge about the SAGV-supporting platforms from
the callers to the SAGV code.
We'll add more platforms to intel_has_sagv(), so IMHO it makes more
sense to move all this to a single function instead of patching all
the callers every time we add SAGV support to a new platform.

The plan is to introduce intel_has_sagv() and then use it to discover
which platforms actually support it.
I thought about keeping the functions with their current skl names,
but found two problems: (i) skl_has_sagv() would become a very
confusing name, and (ii) intel_atomic_commit_tail() doesn't seem to be
calling any functions whose name start with a platform name, so the
"intel_" naming scheme seems make more sense than the "firstplatorm_"
naming scheme here.

We never remembered to set it (so it was zero), but this was not a
problem in the past due to the way handled the hardware registers.
Unfortunately we changed how we set the hardware and forgot to set
intel_crtc->dspaddr_offset.
This started to reflect on a few kms_frontbuffer_tracking subtests
that relied on page flips with CRTCs that don't point to the x:0,y:0
coordinates of the frontbuffer. After the page flip the CRTC was
showing the x:0,y:0 coordinate of the frontbuffer instead of
x:500,y:500. This problem is present even if we don't enable FBC or
PSR.
While trying to bisect it I realized that the first bad commit
actually just gives me a black screen for the mentioned tests instead
of showing the wrong x:0,y:0 offsets. A few commits later the black
screen problem goes away and we get to the point where the code is
today, but I'll consider the black screen as the first bad commit
since it's the point where the IGT subtests start to fail.

Some boards have an entirely passive RGB to VGA bridge, based on DACs
implemented by resistor ladders.
Those might or might not have an i2c bus routed to the VGA connector in
order to access the screen EDIDs.
Add a bridge that doesn't do anything but expose the modes available on the
screen, either based on the EDIDs if available, or based on the XGA
standards.

Now that we have infoframes to report the pixel repeat flag, we can
start using it. Fixes locking the 720x480i and 720x576i modes on my
Dell 2408WFP. Like the 1920x1080i case, they don't fit properly on
the screen, though.

Fixes a purple bar on the left side of the screen with my Dell
2408WFP. It will also be required for supporting the double-clocked
video modes.

We really do need to be using the halved V fields. I had been
confused by the code I was using as a reference because it stored
halved vsync fields but not halved vdisplay, so it looked like I only
needed to divide vdisplay by 2.
This reverts part of Mario's timestamping fixes that prevented
CRTC_HALVE_V from applying, and instead adjusts the timestamping code
to not use the crtc field in that case.
Fixes locking of 1920x1080x60i on my Dell 2408WFP. There are black
bars on the top and bottom, but I suspect that might be an
under/overscan flags problem as opposed to video timings.

Fixes occasional debug spew at boot when connected directly through
HDMI, and probably confusing the HDMI state machine when we go trying
to poke registers for the enable sequence too soon.

On Pi0/1/2, we use an external GPIO line for hotplug detection, since
the HDMI_HOTPLUG register isn't connected to anything. However, with
the Pi3 the HPD GPIO line has moved off to a GPIO expander that will
be tricky to get to (the firmware is constantly polling the expander
using i2c0, so we'll need to coordinate with it).
As a stop-gap, if we don't have a GPIO line, use an EDID probe to
detect connection. Fixes HDMI display on the pi3.

Fixes broken grayscale ramps on many HDMI monitors, where large areas
at the ends of the ramp would all appear as black or white.

With the introduction of bin/render pipelining, the previous job may
not be completed when we start binning the next one. If the previous
job wrote our VBO, IB, or CS textures, then the binning stage might
get stale or uninitialized results.
Fixes the major rendering failure in glmark2 -b terrain.

This reverts commit 1dcd32fb9c54334ec948a0f18174a748d6b14364.
The block size is indeed an equal match, so this can cause performance regressions.

If this happens (and it recently did), we free a structure while part of
it is still in use, which results in non-obvious crashes. The way it's
detached is not trivial (DRM core has to call the connector .destroy
callback and things must be torn down in the right order), so better
detect it and warn early.
