Now that our state comparison functions are pretty complete, we should
enable fastset by default when a modeset can be avoided. Even if we're
not completely certain about the inherited state, we can be certain
after the first modeset that our sw state matches the hw state.
There is one testcase explicitly testing fastset,
kms_panel_fitting.atomic-fastset but other testcases do so indirectly
because most tests don't clean up the display during exit, or otherwise
indirectly preserve mode by doing igt_display_reset or inheriting during
init.

On lynxpoint the bios sometimes sets up the backlight using the CPU
display, but the driver expects using the PWM PCH override register.
Read the value from the CPU register, then convert it to the other
units by converting from the old duty cycle, to freq, to the new units.
This value is then programmed in the override register, after which
we set the override and disable the CPU display control. This allows
us to switch the source without flickering, and make the backlight
controls work in the driver.
Changes since v1:
- Read BLC_PWM_CPU_CTL2 to cpu_ctl2.
- Clean up cpu_mode if slightly.
- Always disable BLM_PWM_ENABLE in cpu_ctl2.
Changes since v2:
- Simplify cpu_mode handling (Jani)

indicator. Also check for crtc->state->active.

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

When reading GEN11_GT_INTR_DWx closely after enabling the interrupts
in gen11_irq_postinstall, the returned value is garbage. This can
cause other parts of the setup code (e.g. gen11_reset_one_iir) to
think that there are interrupts to be cleared when there are none.
The garbage value is only seen on the first read done after the enable,
so this looks like a posting issue. Adding a posting read after enabling
the interrupts does indeed fix the problem.
Note that the posting read has been purposely added outside of
gen11_master_intr_enable since the issue has only been observed when the
full interrupt setup is performed.

PSR mode: PSR1 enabled
Source PSR ctl: enabled [0x81f00e26]

The 'Main link in standby mode' was removed as it is not useful but
if needed by someone the information is still in the register value
of 'Source PSR ctl' inside of the brackets, PSR mode and Enabled was
squashed into PSR mode, some renames and reorders and we have this

Before adding yet another copy of struct live_test and its handler,
refactor the existing code into a common framework for live selftests.
For many live selftests, we want to know if the GPU hung or otherwise
misbehaved during the execution of the test (beyond any infraction in
the behaviour under test), live_test provides this by comparing the
GPU state before and after, alerting if it unexpectedly changed (e.g.
the reset counter changed). It also ensures that the GPU is idle before
and after the test, so that residual code running on the GPU is flushed

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.

Mixed C99 and kernel types use is getting ugly. Prefer kernel types.

The evict selftests presumed that all objects in use had been allocated
by itself. This is a dubious claim and so instead of asserting complete
control over the object lists, take (temporary) ownership of them
instead.

Since commit d4ccceb055 ("drm/i915/icl: Ringbuffer interrupt handling")
we have required a mechanism to avoid touching the interrupt hardware
for breadcrumbs, superseding our mock interface for selftests.
The residual problem (ideas welcome) is in probing the mock ring
registers for ring_is_idle. Hmm, maybe we should just install
mock handlers for i915->uncore.mmio__write and friends? Only problem
being is that we would to truly mock some expected reads. :(

Since we have the ppgtt we want to test, we can ask it directly if it is
suitable for the hugepage test we intend to undertake.

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.
