All the low level cdclk bits are present, so let's add the required
hooks to reconfigure cdclk on the fly.
Cannonlake also needs to adjust the minimal pixel rate
as gen9 platforms. Specially for the Azalia audio case.
v2: Rebase due to cnl_sanitize_cdclk()
v3: Rebased by Rodrigo on top of Ville's cdclk rework.
v4: Rebase moving cnl_calc_cdclk up to follow same order
as previous platforms.
v2: Squash drm/i915/cnl: Adjust min pixel rate. to address
the current limitation where CDCLK cannot be set to 168MHz
if audio is used with 96MHz. (Imre)
v3: adjust some of the clock limits within
bdw_adjust_min_pipe_pixel_rate. (Ville/DK/Imre).
Fix commit message messed by squash.

Implement the CNL display init/uninit sequence as outlined in Bspec.
Quite similar to SKL/BXT. The main complicaiton is probably the extra
procmon setup we must do based on the process/voltage information we
can read out from some register.
v2: s/skl_dbuf/gen9_dbuf/ to follow upstream
bxt needed a cdclk sanitize step, so let's add it for cnl too
v3: s/CHICKEN_MISC_1/CHICKEN_MISC_2/ (Ander)
v4: Rebased by Rodrigo after Ville's cdclk rework
v5: Removed unecessary Aux IO forced enable/disable, Fix DW10 setup
Fix procpon Mask. (Credits-to Paulo and Clint)
Remove A0 workaround.
v6: Rebased on top of recent code (Rodrigo).
v7: Respect the order of sanitize_ after set_
(Done by Rodrigo, Requested by Ville)
v8: Commit message updated to matvh v5 changes besides
Remove unused DW8 and an extra blank line. (all noticed

v9: Remove __attribute__((unused)) added on latest version

Add support for changing the cdclk frequency on CNL. Again, quite
similar to BXT, but there are some annoying differences which means
trying to share more code might not be feasible:
* PLL ratio now lives in the PLL enable register
* pcode came from SKL, not from BXT
We support three cdclk frequencies: 168,336,528 Mhz. The first two
use the same PLL frequency, the last one uses a different one meaning
we once again may need to toggle the PLL off and on when changing
cdclk.
v2: Rebased by Rodrigo on top of Ville's cdclk rework.
v3: Respect order of set_ bellow get_ (Ville)
v4: Added __attribute__((unused)) to avoid broken compilation with Werror.

Add support for reading out the cdclk frequency from the hardware on
CNL. Very similar to BXT, with a few new twists and turns:
* the PLL is now called CDCLK PLL, not DE PLL
* reference clock can be 24 MHz in addition to the 19.2 MHz BXT had
* the ratio now lives in the PLL enable register
* Only 1x and 2x CD2X dividers are supported
v2: Deal with PLL lock bit the same way as BXT/SKL do now
v3: DSSM refclk indicator is bit 31 not 24 (Ander)
v4: Rebased by Rodrigo after Ville's cdclk rework.
v5: Set cdclk to the ref clock as previous platforms. (Imre)

Pass crtc_state to the enable callback, and connector_state to all callbacks.
This will eliminate the need to guess for the correct pipe in these
callbacks.
The crtc state is required for pch_enable_backlight to obtain the correct
cpu_transcoder.
intel_dp_aux_backlight's setup function is called before hw readout, so
crtc_state and connector_state->best_encoder are NULL in the enable()
and set() callbacks.
This fixes the following series of warns from intel_get_pipe_from_connector:

Make use of the irq_preinstall/uninstall callback to clear and
mask all interrupts. Use write 1 to clear as documented by the
data sheet (writing a 0 seems to have cleared interrupt status
too). Remove fsl_dcu_drm_irq_init and call drm_irq_install
directly from fsl_dcu_load makes error handling a bit simpler.
Do not set irq_enabled since drm_irq_install is taking care of
it.

So let's force it on the virtual detection.
Also it is still the only silicon for now on this PCH,
so WARN otherwise.
v2: Rebased on top of Cannonlake and added the missed
debug message as pointed by DK.

Coffee Lake is a Intel® Processor containing Intel® HD Graphics
following Kabylake.
It is Gen9 graphics based platform on top of CNP PCH.
Let's start by adding the platform definition based on previous
platforms but yet as preliminary_hw_support.
On following patches we will start adding PCI IDs and the
platform specific changes.
v2: Also add BS2 ring that is present on GT3. As on KBL, according
spec: "GT3 also has additional media blocks with second instance
of VEBox and VDBox each", i.e. BSD2 ring in our case. Noticed
when reviewing PCI ID patches.
v3: CFL_PLATFORM instead for CFL_FEATURES because it contains
Platform information and no new features when compared to
BDW_FEATURES definition.
v4: Rebased on top of Cannonlake patches.

Even if CONFIG_DRM_AMDGPU_CIK is enabled.
There is no feature parity yet for CIK, in particular amdgpu doesn't
support HDMI/DisplayPort audio without DC.
v2:
* Clarify the lack of feature parity being related to HDMI/DP audio.
* Fix "SI" typo in DRM_AMDGPU_CIK help entry.

of these options for using the out-of-tree amdgpu driver instead of the

Originally we would enable and disable the breadcrumb interrupt
immediately on demand. This was slow enough to have a large impact
(>30%) on tasks that hopped between engines. However, by using a shadow
to keep the irq alive for an extra interrupt (see commit 67b807a89230
("drm/i915: Delay disabling the user interrupt for breadcrumbs")) and
by recently reducing the cost in adding ourselves to the signal tree, we
no longer need to spin-request during await_request to avoid delays in
throughput tests. Without the earlier patches to stop the wakeup when
signaling if the irq was already active, we saw no improvement in
execbuf overhead (and corresponding contention in other clients) despite
the removal of the spinner in a simple test like glxgears. This means
there will be scenarios where now we spend longer enabling the interrupt
than we would have spent spinning, but these are not likely to have as
noticeable an impact as the high frequency test cases (where there
should not be any regression).
Ulterior motive: generalising the engine->sync_to to handle different
types of semaphores and non-semaphores.

The important condition that we need to check after enabling the
interrupt for signaling is whether the request completed in the process
(and so we missed that interrupt). A large cost in enabling the
signaling (rather than waiters) is in waking up the auxiliary signaling
thread, but we only need to do so to catch that missed interrupt. If we
know we didn't miss any interrupts (because we didn't arm the interrupt)
then we can skip waking the auxiliary thread.
