So apparently jiffies<->nsec<->ktime isn't accurate or something. At

Stuff I've tried and thrown out again:
- Sampling the before timestamp before jiffies. Doesn't improve test
path rate at all.
- Using jiffies. Way to inaccurate, which means way too much drift
with signals plus automatic ioctl restarting in userspace. In
hindsight we should have used an absolute timeout, but hey we need

- Trying to figure out where accuracy gets lost. gl testcase really
don't care all that much about this (as long as isn't not massively
off), it's just that the testcase gets a bit upset if it receives an
EITME with timeout > 0.
So as long as we're in the ballbark it's good enough. So patch
everything up if we're at most one jiffies off. I get's me a solid

drm/i915: Reject modeset when the same digital port is used more than once
On pre-HSW we have two encoders per digital port: one HDMI, one DP.
However they are the same physical port in hardware and we can't enable
both at the same time. Reject the modeset if the user attempts this.
So far we've been saved by the fact that we never see both HDMI and DP
connectors as connected. But if the user decides to force a mode anyway,
all kinds of funny stuff might happen.
Unfortunately we don't seem to have any way to inform userspace that
such configurations are invalid except by returning an error from
setcrtc. possible_clones only covers real cloning situations, and
looking at the connector names doesn't work either since we don't
always register both connectors for the same port. I suppose the
only way to fix that would be to expose only a single encoder per
digital port like we do on HSW+ but that would be a fairly large
undertaking for little gain.
kms_setmode hits this since it forces modes on non-connected VGA and
HDMI connectors. Previosuly it just resulted in weirdness such as
failed link training. With this patch it will now get an error back
from the kernel and will die with an assert since it thinks that the
configuration should be fine.

drm/i915: mask RPS IRQs properly when disabling RPS
Atm, igt/gem_reset_stats can trigger the recently added WARN on
left-over PM_IIR bits in gen6_enable_rps_interrupts(). There are two
reasons for this:
1. we call intel_enable_gt_powersave() without a preceeding
intel_disable_gt_powersave()
2. gen6_disable_rps_interrupts() doesn't mask interrupts in PM_IMR
1. means RPS interrupts will remain enabled and can be serviced during
the HW initialization after a GPU reset. 2. means even if we called
gen6_disable_rps_interrupts() any new RPS interrupt during RPS
initialization would still propagate to PM_IIR too early (though
wouldn't be serviced).
This patch solves the 2. issue by also masking interrupts in PM_IMR, the
following patch fixes 1. getting rid of the WARN. This also makes
intel_enable_gt_powersave() and intel_disable_gt_powersave() more
symmetric.
Since gen6_disable_rps_interrupts() is called during driver loading with
i915 interrupts disabled add a new version of gen6_disable_pm_irq() that
doesn't WARN for this.
Also while at it, get the irq_lock around the whole PM_IMR/IER/IIR
programming sequence and make sure that any queued PM_IIR bit is also
cleared.
The WARN was caught by PRTS after I sent my previous RPS sanitizing
patchset and I could easily reproduce it on HSW. To actually fix it we
also need the next patch.

drm/i915: Handle runtime pm in the CRC setup code
The crc code doesn't handle anything really that could drop the
register state (by design so that we have less complexity). Which
means userspace may only start crc capture once the pipe is fully set
up.
With an i-g-t patch this will be the case, but there's still the
problem that this results in obscure unclaimed register write
failures. Which is a pain to debug.
So instead make sure we don't have the basic unclaimed register write
failure by grabbing runtime pm references. And reject completely
invalid requests with -EIO. This is still racy of course, but for a
test library we don't really care - if userspace shuts down the pipe
right afterwards the entire setup will be lost anyway.

When doing a nop modeset we currently leave crtc->new_config point at
the already freed temporary pipe_config. That will anger the sanity
checks in intel_modeset_update_state() when the nop modeset gets
followed by a GPU reset on gen3/4 where the display block gets fully
reinitialized during the reset.

drm: rcar-du: Fix NULL encoder pointer dereference
The DRM connector's encoder pointer is managed internally by the DRM
core and set to NULL when the DRM connector is disconnected from the
CRTC it was attached to. This results in a NULL pointer dereference in
the HDMI connector functions when trying to call the associated slave
encoder's operations.
Fix this by retrieving the slave encoder pointer from the R-Car
connector structure instead of the DRM connector structure.

v2: Broke out individual context dumping into a new function as the indentation
was getting a bit crazy. Added notification of contexts with no gem object for
debugging purposes. Removed unnecessary pin_pages and unpin_pages, replaced
with explicit get_pages for the context object as there may be no backing store
allocated at this time (Comment for get_pages says "Ensure that the associated
pages are gathered from the backing storage and pinned into our object").
Improved error checking - get_pages and get_page are checked for failure.

drm/nouveau/bios: log if auxch accesses fail, also return 0x00 from rd when it does
