drm/i915: Stop the machine whilst capturing the GPU crash dump
The error state is purposefully racy as we expect it to be called at any
time and so have avoided any locking whilst capturing the crash dump.
However, with multi-engine GPUs and multiple CPUs, those races can
manifest into OOPSes as we attempt to chase dangling pointers freed on
other CPUs. Under discussion are lots of ways to slow down normal
operation in order to protect the post-mortem error capture, but what it
we take the opposite approach and freeze the machine whilst the error
capture runs (note the GPU may still running, but as long as we don't
process any of the results the driver's bookkeeping will be static).
Note that by of itself, this is not a complete fix. It also depends on
the compiler barriers in list_add/list_del to prevent traversing the
lists into the void. We also depend that we only require state from
carefully controlled sources - i.e. all the state we require for
post-mortem debugging should be reachable from the request itself so
that we only have to worry about retrieving the request carefully. Once
we have the request, we know that all pointers from it are intact.
v2: Avoid drm_clflush_pages() inside stop_machine() as it may use
stop_machine() itself for its wbinvd fallback.

drm/i915: Allow disabling error capture
We currently capture the GPU state after we detect a hang. This is vital
for us to both triage and debug hangs in the wild (post-mortem
debugging). However, it comes at the cost of running some potentially
dangerous code (since it has to make very few assumption about the state
of the driver) that is quite resource intensive.
This patch introduces both a method to disable error capture at runtime
(for users who hit bugs at runtime and need a workaround) and to disable
error capture at compiletime (for realtime users who want to minimise
any possible latency, and never require error capture, saving ~30k of
code). The cost is that we now have to be wary of (and test!) a kconfig
flag and a module parameter. The effect of the module parameter is easy
to verify through code inspection and runtime testing, but a kconfig flag
needs regular compile checking.

drm/i915/gen9: fix DDB partitioning for multi-screen cases
With the previous code we were only recomputing the DDB partitioning
for the CRTCs included in the atomic commit, so any other active CRTCs
would end up having their DDB registers zeroed. In this patch we make
sure that the computed state starts as a copy of the current
partitioning, and then we only zero the DDBs that we're actually
going to recompute.
How to reproduce the bug:
1 - Enable the primary plane on pipe A
2 - Enable the primary plane on pipe B
3 - Enable the cursor or sprite plane on pipe A
Step 3 will zero the DDB partitioning for pipe B since it's not
included in the commit that enabled the cursor or sprite for pipe A.
I expect this to fix many FIFO underrun problems on gen9+.
v2:
- Mention the cursor on the steps to reproduce the problem (Paulo).
- Add Testcase tag provided by Maarten (Maarten).

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

drm/i915: Allow PCH DPLL sharing regardless of DPLL_SDVO_HIGH_SPEED
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.

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

This should only help on situations with Y tiling + 90/270 rotation +

drm/i915: don't forget to set intel_crtc->dspaddr_offset on SKL+
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.

drm/i915: Register shadow VGA even when it produces spurious detection results
Having a shadow VGA connector is useful for testing purposes. We
currently skip registering the connector on machines where the
CRT detect falsely reports it as connected. Let's instead move the
the blacklist check to the detect callback (and hpd setup) and
if we get a match we always report the connector as disconnected.
This way we get a shadow VGA connector to help with testing, while
we still avoid the user facing problems from the incorrect
detection results.
commit
8ca4013d702d ("CHROMIUM: i915: Add DMI override to skip CRT
initialization on ZGB") doesn't provide much in the way of details
as to why 'ACER ZGB' was added to the blacklist. Trying to trace it
further leads me to a chromeos bugreport I can't access. So based on
the fact that the commit added the
"/* Skip machines without VGA that falsely report hotplug events */"
comment, I'm going to assume that it was just spurious CRT detection.
So it should be safe to move the blacklist to just block the detection
and hpd without causing a regression on said machine.
In fact Stéphane confirmed on irc that the problem was indeed just
crappy hotplug detect:
"22:29 < marcheu> vsyrjala: the port isn't there, but the load detect is
improperly stubbed in hw
22:29 < marcheu> vsyrjala: so it floats"

"disconnected" if there is no EDID.
This stuff used to broken already, I think, but it got more broken by

drm/i915: Move long hpd handling into the hotplug work
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.

Whilst we reset the GPU, we want to prevent execlists from submitting

disable the irq (and drain the irq tasklet) around the reset. When we
enable it again afters, the interrupt queue should be empty and we can
reinitialise from a known state without fear of the tasklet running
concurrently.

After a GPU reset, we want to replay our queue of requests. However, the
GPU reset clobbered the state and we only fixup the state for the guilty

we recover as completely as possible. However, we need to clear the sw
tracking of the ELSP ports even for innocent requests, so move the clear
to the common path of init_hw (from reset_hw).

drm/i915/execlists: Reinitialise context image after GPU hang
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.
