drm/i915: Don't try to use the hardware frame counter with i965gm TV output
On i965gm the hardware frame counter does not work when
the TV encoder is active. So let's not try to consult
the hardware frame counter in that case. Instead we'll
fall back to the timestamp based guesstimation method
used on gen2.
Note that the pipe timings generated by the TV encoder
are also rather peculiar. Apparently the pipe wants to
run at a much higher speed (related to the oversample
clock somehow it seems) but during the vertical active
period the TV encoder stalls the pipe every few lines
to keep its speed in check. But once the vertical
blanking period is reached the pipe gets to run at full
speed. This means our vblank timestamp estimates are
suspect. Fixing all that would require quite a bit
more work. This simple fix at least avoids the nasty
vblank timeouts that are happening currently.
Curiously the frame counter works just fine on i945gm
and gm45. I don't really understand what kind of mishap
occurred with the hardware design on i965gm. Sadly
I wasn't able to find any chicken bits etc. that would
fix the frame counter :(

drm/i915: Remove GPU reset dependence on struct_mutex
Now that the submission backends are controlled via their own spinlocks,
with a wave of a magic wand we can lift the struct_mutex requirement
around GPU reset. That is we allow the submission frontend (userspace)
to keep on submitting while we process the GPU reset as we can suspend
the backend independently.
The major change is around the backoff/handoff strategy for performing
the reset. With no mutex deadlock, we no longer have to coordinate with
any waiter, and just perform the reset immediately.

drm/i915/guc: Disable global reset
The guc (and huc) currently inexcruitably depend on struct_mutex for
device reinitialisation from inside the reset, and indeed taking any
mutex here is verboten (as we must be able to reset from underneath any
of our mutexes). That makes recovering the guc unviable without, for
example, reserving contiguous vma space and pages for it to use.
The plan to re-enable global reset for the GuC centres around reusing the
WOPM reserved space at the top of the aperture (that we know we can
populate a contiguous range large enough to dma xfer the fw image).
In the meantime, hopefully no one even notices as the device-reset is
only used as a backup to the per-engine resets for handling GPU hangs.

drm/i915: Validate userspace-provided color management LUT's (v4)
We currently program userspace-provided gamma and degamma LUT's into our
hardware without really checking to see whether they satisfy our
hardware's rules. We should try to catch tables that are invalid for
our hardware early and reject the atomic transaction.
All of our platforms that accept a degamma LUT expect that the entries
in the LUT are always flat or increasing, never decreasing. Also, our
GLK and ICL platforms only accept degamma tables with r=g=b entries; so
we should also add the relevant checks for that in anticipation of
degamma support landing for those platforms.
v2:
- Use new API (single check function with bitmask of tests to apply)
- Call helper for our gamma table as well (with no additional tests
specified) so that the table size will be validated.
v3:
- Don't call on the gamma table since the LUT size is already tested at
property blob upload and we don't have any additional hardware
constraints for that LUT.
v4:
- Apply equal color channel check on gen10 as well; the bspec has some
strange tagging for CNL platforms, but this appears to apply there as
well. (Ville)

cause other parts of the setup code (e.g. gen11_reset_one_iir) to

The garbage value is only seen on the first read done after the enable,

drm/i915/dsi: Fix pipe_bpp for handling for 6 bpc pixel-formats
There are 3 problems with the dsi code's pipe_bpp handling for 6 bpc
pixel-formats which this commit addresses:
1) It assumes that the pipe_bpp is the same as the bpp going over the dsi
lanes. This assumption is not valid for MIPI_DSI_FMT_RGB666, where pipe_bpp
should be 18 so that we do proper dithering but we actually send 24 bpp
over the dsi lanes (MIPI_DSI_FMT_RGB666_PACKED sends 18 bpp).
This assumption is enforced by an assert in *_dsi_get_pclk(). This assert
triggers on the initial hw-state readback on BYT/CHT devices which use
MIPI_DSI_FMT_RGB666, such as the Prowise PT301 tablet. PIPECONF is set to
6BPC / 18 bpp by the GOP, while mipi_dsi_pixel_format_to_bpp() returns 24.
This commits switches the calculations in *_dsi_get_pclk() to use the bpp
from mipi_dsi_pixel_format_to_bpp(intel_dsi->pixel_format) which
returns the bpp going over the mipi lanes and drops the assert.
2) On BXT bxt_dsi_get_pipe_config() wrongly overrides the pipe_bpp which
i9xx_get_pipe_config() reads from PIPECONF with the return value from
mipi_dsi_pixel_format_to_bpp(). This avoids the assert from 1. but is wrong
since the pipe is actually running at the value configured in PIPECONF.
This commit drops the override of pipe_bpp from bxt_dsi_get_pipe_config().
3) The dsi encoder's compute_config() never assigns a value to pipe_bpp,
unlike most other encoders. Falling back on compute_baseline_pipe_bpp()
which always picks 24. 24 is only correct for MIPI_DSI_FMT_RGB88 for the
others we should use 18 bpp so that we correctly do 6bpc color dithering.
This commit adds code to intel_dsi_compute_config() to properly set
pipe_bpp based on intel_dsi->pixel_format.

drm/i915/breadcrumbs: Drop assertion that we've already enabled irqs
The motivation for introducing the check that we only enable breadcrumb
irqs if the device's irq was installed was once upon a time we waited
during suspend after disabling interrupts (which was quite slow until
the bug was discovered). Since then we have the notion of pinning the
breadcrumb irq, broadening it from the sole purpose of user interrupt
notification and waiting, and more importantly decoupling it from a very
defined time period during which enabling the irq was expected. So stop
insisting the irq is installed before we setup our IMR masks, if the IER
isn't yet enabled, nothing will happen and we will timeout instead,
revealing the lack of irq in the hang debug messages.

drm/i915: Pass down rc in intel_encoder->compute_config()
Something that I completely missed when implementing the new MST VCPI
atomic helpers is that with those helpers, there's technically a chance
of us having to grab additional modeset locks in ->compute_config() and
furthermore, that means we have the potential to hit a normal modeset
deadlock. However, because ->compute_config() only returns a bool this
means we can't return -EDEADLK when we need to drop locks and try again
which means we end up just failing the atomic check permanently. Whoops.
So, fix this by modifying ->compute_config() to pass down an actual
error code instead of a bool so that the atomic check can be restarted
on modeset deadlocks.
Thanks to Ville Syrjälä for pointing this out!
Changes since v1:
* Add some newlines
* Return only -EINVAL from hsw_crt_compute_config()
* Propogate return code from intel_dp_compute_dsc_params()
* Change all of the intel_dp_compute_link_config*() variants
* Don't miss if (hdmi_port_clock_valid()) branch in
intel_hdmi_compute_config()

So we have a situation where we do not pull in <linux/types.h>
when building for alpha and for ia64 we need even more definitions
are required.
Two invasive fixes where considered:
- Change all declarations of arch_irqs_disabled_flags() to use bool
- Add include of <linux/types.h> to all files that uses bool for
arch_irqs_disabled_flags
To invasive with a too high pain/benefit ratio, so dropped.
They would not cover ia64 either.
Some less invasive fixes was also considered:
- Add include of <linux/types.h> to drm_util.h
- Add include of <linux/interrupt.h> to drm_util.h
The first was dropped as this did not cover the ia64 case.
The latter was considered the best option as there could
be other similar cases and we would like the header files below
include/drm/ to be selfcontained.
So we end up pulling in a lot of stuff not needed, but this is
the price we pay in drm/ because the kernel headers are not all
selfcontained.
While at it, ordred the includefiles in drm_util in alphabetical order.
Build tested with alpha,ia64,arm,x86 with allmodconfig and allyesconfig.
v2:
- fix ia64 build, changed to include interrupt.h
- sort include files alphabetically

drm/i915: Pass down rc in intel_encoder->compute_config()
Something that I completely missed when implementing the new MST VCPI
atomic helpers is that with those helpers, there's technically a chance
of us having to grab additional modeset locks in ->compute_config() and
furthermore, that means we have the potential to hit a normal modeset
deadlock. However, because ->compute_config() only returns a bool this
means we can't return -EDEADLK when we need to drop locks and try again
which means we end up just failing the atomic check permanently. Whoops.
So, fix this by modifying ->compute_config() to pass down an actual
error code instead of a bool so that the atomic check can be restarted
on modeset deadlocks.
Thanks to Ville Syrjälä for pointing this out!
Changes since v1:
* Add some newlines
* Return only -EINVAL from hsw_crt_compute_config()
* Propogate return code from intel_dp_compute_dsc_params()
* Change all of the intel_dp_compute_link_config*() variants
* Don't miss if (hdmi_port_clock_valid()) branch in
intel_hdmi_compute_config()

drm/i915/userptr: Avoid struct_mutex recursion for mmu_invalidate_range_start
Since commit
93065ac753e4 ("mm, oom: distinguish blockable mode for mmu
notifiers") we have been able to report failure from
mmu_invalidate_range_start which allows us to use a trylock on the
struct_mutex to avoid potential recursion and report -EBUSY instead.
Furthermore, this allows us to pull the work into the main callback and
avoid the sleight-of-hand in using a workqueue to avoid lockdep.
However, not all paths to mmu_invalidate_range_start are prepared to
handle failure, so instead of reporting the recursion, deal with it by
propagating the failure upwards, who can decide themselves to handle it
or report it.
v2: Mark up the recursive lock behaviour and comment on the various weak
points.
v3: Follow commit
3824e41975ae ("drm/i915: Use mutex_lock_killable() from
inside the shrinker") and also use mutex_lock_killable().

drm/i915/icl: Detect port F presence via VBT
Registering an output for a non-existent port (on a given SKU) can lead
to problems when trying to use the port, for instance timeouts during
power well enabling. Since there are no strap bits for port detection we
have to rely on VBT for this, so do that here.
There are no known SKUs where any of the A-E ports are non-existent, so
to reduce the likelihood of breakage due to incorrect VBT information,
do this detection only for port F (which is known to be missing on some
ICL SKUs).
