drm/nouveau: fix duplication of nv50_head_atom struct
nv50_head_atomic_duplicate_state() makes a copy of nv50_head_atom
struct. This patch adds copying of struct member named "or", which
previously was left uninitialized in the duplicated structure.
Due to this bug, incorrect nhsync and nvsync values were sometimes used.
In my particular case, that lead to a mismatch between the output
resolution of the graphics device (GeForce GT 630 OEM) and the reported
input signal resolution on the display. xrandr reported 1680x1050, but
the display reported 1280x1024. As a result of this mismatch, the output
on the display looked like it was cropped (only part of the output was
actually visible on the display).
git bisect pointed to commit
2ca7fb5c1cc6 ("drm/nouveau/kms/nv50: handle
SetControlOutputResource from head"), which added the member "or" to
nv50_head_atom structure, but forgot to copy it in
nv50_head_atomic_duplicate_state().

drm/nouveau/i2c: Disable i2c bus access after ->fini()
For a while, we've had the problem of i2c bus access not grabbing
a runtime PM ref when it's being used in userspace by i2c-dev, resulting
in nouveau spamming the kernel log with errors if anything attempts to
access the i2c bus while the GPU is in runtime suspend. An example:
[ 130.078386] nouveau 0000:01:00.0: i2c: aux 000d: begin idle timeout
ffffffff
Since the GPU is in runtime suspend, the MMIO region that the i2c bus is
on isn't accessible. On x86, the standard behavior for accessing an
unavailable MMIO region is to just return ~0.
Except, that turned out to be a lie. While computers with a clean
concious will return ~0 in this scenario, some machines will actually
completely hang a CPU on certian bad MMIO accesses. This was witnessed
with someone's Lenovo ThinkPad P50, where sensors-detect attempting to
access the i2c bus while the GPU was suspended would result in a CPU
hang:

watchdog: BUG: soft lockup - CPU#5 stuck for 23s! [sensors-detect:12438]
Yikes! While I wanted to try to make it so that accessing an i2c bus on
nouveau would wake up the GPU as needed, airlied pointed out that pretty
much any usecase for userspace accessing an i2c bus on a GPU (mainly for
the DDC brightness control that some displays have) is going to only be
useful while there's at least one display enabled on the GPU anyway, and
the GPU never sleeps while there's displays running.
Since teaching the i2c bus to wake up the GPU on userspace accesses is a
good deal more difficult than it might seem, mostly due to the fact that
we have to use the i2c bus during runtime resume of the GPU, we instead
opt for the easiest solution: don't let userspace access i2c busses on
the GPU at all while it's in runtime suspend.
Changes since v1:
* Also disable i2c busses that run over DP AUX

drm/msm/gpu: Attach to the GPU GX power domain
99.999% of the time during normal operation the GMU is responsible
for power and clock control on the GX domain and the CPU remains
blissfully unaware. However, there is one situation where the CPU
needs to get involved:
The power sequencing rules dictate that the GX needs to be turned
off before the CX so that the CX can be turned on before the GX
during power up. During normal operation when the CPU is taking
down the CX domain a stop command is sent to the GMU which turns
off the GX domain and then the CPU handles the CX domain.
But if the GMU happened to be unresponsive while the GX domain was
left then the CPU will need to step in and turn off the GX domain
before resetting the CX and rebooting the GMU. This unfortunately
means that the CPU needs to be marginally aware of the GX domain
even though it is expected to usually keep its hands off.
To support this we create a semi-disabled GX power domain that
does nothing to the hardware on power up but tries to shut it
down normally on power down. In this method the reference counting
is correct and we can step in with the pm_runtime_put() at the right
time during the failure path.
This patch sets up the connection to the GX power domain and does
the magic to "enable" and disable it at the right points.

- The definition states it's in # of frames
- CRTC treats it like it's ms
- frame_done_timeout comment thinks it's Hz, but it stores ms
- frame_done timer is setup such that it _should_ be in frames, but the
timeout is super long
So this patch tries to interpret what the driver really wants. I've
de-centralized the #define since the consumers are expecting different
units.
For crtc, we just use 60ms since that's what it was doing before.
Perhaps we could get fancy and scale with vrefresh, but that's for
another time.
For encoder, fix the comments and rename frame_done_timeout so it's
obvious what the units are. In practice, frame_done_timeout is really
just checked against 0 || !0, which I guess is why the units being wrong
didn't matter. I've also dropped the timeout from the previous 60 frames
to 5. That seems like more than enough time to give up on a frame, and
my guess is that no one intended for the timeout to _actually_ be 60
frames.

calculate it once and set it in both places at the same time.

drm/msm: Remove pm_runtime calls from msm_iommu.c
Currently the IOMMU code calls pm_runtime_get/put on the GPU or display
device before doing a IOMMU operation. This was because usually the
IOMMU driver didn't do power control of its own and since the hardware
used the same clocks and power as the respective multimedia device it
was a easy way to make sure that the power was available.
Now two things have changed. First, the SMMU devices can do their own power
control and more important bringing up the a6xx GPU isn't as easy as
turning on some clocks. To bring the GPU up we need the GMU which itself
needs the IOMMU so we have a chicken and egg problem.
Luckily this is easily fixed by removing the pm_runtime calls from the
functions and letting the device link to the IOMMU device handle the magic.

few pinned pages in CMA will lead to failure to find the

drm/tegra: gem: Fix CPU-cache maintenance for BO's allocated using get_pages()
The allocated pages need to be invalidated in CPU caches. On ARM32 the
DMA_BIDIRECTIONAL flag only ensures that data is written-back to DRAM and
the data stays in CPU cache lines. While the DMA_FROM_DEVICE flag ensures
that the corresponding CPU cache lines are getting invalidated and nothing
more, that's exactly what is needed for a newly allocated pages.
This fixes randomly failing rendercheck tests on Tegra30 using the
Opentegra driver for tests that use small-sized pixmaps (10x10 and less,
i.e. 1-2 memory pages) because apparently CPU reads out stale data from
caches and/or that data is getting evicted to DRAM at the time of HW job
execution.
