DSC is supported on eDP starting GEN 10 display (on GLK) and on DP starting
GEN 11.
This patch implements the discovery phase of DSC. On hotplug,
source reads the DSC DPCD register set (0x00060 - 0x0006F) to
read the decompression capabilities of the sink device.
This entire block of registers is cached in intel_dp so that
capability information can be used during DSC configuration
phase during compute_config phase of the modeset.
For eDP, this caching happens during the eDP initialization.
This caching is done only for eDP and DP rev >= 1.4
v5:
* Fix the block comment (Gaurav)
* Fix the commit message DSC DPCD addresses (Gaurav)
* Use DRM_ERROR for dpcd_read fail (Gaurav,Anusha)
v4:
* Cache these only for Gen >= 11
v3:
* Remove the dsc_sink_support field in intel_dp (Jani N)
v2:
* Clear the cached registers on hotplug always (Jani N)
* Combine the eDP and DP caching in same function (Jani N)

Add the newly added slice_row_per_frame parameter
in the Picture Parameter Set registers.
This defines the number of vertically stacked slices
in a frame.

Program the timeout values (in escape clock) for HS TX, LP RX and TA
timeout.
HX TX: Ensure that host does not continuously transmit in the HS
state. If this timer expires, then host will gracefully end its HS
transmission and allow the link to enter into LP state.
LP RX: Monitor the length of LP receptions from Peripheral. If timeout
happens then host will drive the stop state onto all data lanes (only
Data Lane 0 should be receiving anything from the Peripheral). This
effectively takes back ownership of the bus transmit in the HS state.
TA timeout: Timeout valuefor monitoring Bus Turn-Around (BTA) sequence.
BTA sequence should complete within a bounded amount of time, with
peripheral acknowledging BTA by driving the stop state.
v2 by Jani:
- Rebase
- Use intel_dsi_bitrate() and intel_dsi_tlpx_ns(intel_dsi)
- Squash HX TX, LP RX and TA timeout into one patch
- Fix bspec mode set sequence reference
- Add FIXME about two timeouts

Driver needs payload/header credits for sending any command
and data over DSI link. These credits are released once command
or data sent to link. This patch adds functions to wait for releasing
of payload and header credits.
As per BSPEC, driver needs to ensure that all of commands/data
has been dispatched to panel before the transcoder is enabled.
This patch implement those steps i.e. sending NOP DCS command,
wait for header/payload credit to be released etc.
v2 by Jani:
- squash the credit wait helpers patch with the first user
- pass dev_priv to the credit wait helpers
- bikeshed credit helper names
- wait for *at least* the current maximum number of credits
- indentation fix
- add helpers for credits available

When using softpin it's not enough to just pad the vma size, we also
need to ensure the vma offset is at the start of the pt boundary, if we
plan to utilize 64K pages. Therefore to improve test coverage we should
use both aligned and unaligned gtt offsets in igt_write_huge.

If we reduce the suspend function for intel_opregion to do the minimum
required, the resume function can also do the simple task of notifier
the ACPI bios that we are back. This avoid some nasty restrictions on
the likes of register_acpi_notifier() that are not allowed during the
early phase of resume.
v2: Keep the order of acpi notify vs turning off ardy/drdy the same.

If we can prevent stray writes from landing in the scratch page, we can
reuse the same page and same scratch PT for all contexts without fear of
information leaks and side-channels.

Record the scratch PTE encoding upon creation rather than recomputing
the bits everytime. This is important for the next patch where we forgo
having a valid scratch page with which we may compute the bits and so
require keeping the PTE value instead.
v2: Fix up scrub_64K to use scratch_pte as well.

intel_fb_pitch_limit() has the parameters pixel_format and fb_modifier
switched in their positions. The parameters are however used correctly,
but change the order for consistency.
Also use kernel data types for both parameters.

The vm of two contexts are supposed to be independent, such that a stray
write by one cannot be detected by another. Normally the GTT is filled
explicitly by userspace, but the space in between objects is filled with
a scratch page -- and that scratch page should not be able to form an
inter-context backchannel.

While checking the opportunity to add a display_gen
check to allow glk and cnl to be on same bucket I noticed
these FIXME cases here.
So I got the confirmation from HW architect that we actually
never needed this workaround.
"GLK supports 2 pixel per clock, so pixel clock can be up to 2 * cdclk."
So, this reverts commit 97f55ca5b662 ("drm/i915/glk: limit pixel
clock to 99% of cdclk workaround")

commit ac657f6461e5 ("drm/i915: Introduce IS_GEN macro") introduced
GEN_FOREVER that was never used.
My first attempt was to rename it to FOREVER since GEN is
already part of the macro. Then I used coccinelle to change all
-INTEL_GEN(e1) >= e2
+INTEL_GEN_RANGE(e1, e2, FOREVER)
-INTEL_GEN(e1) <= e2
+INTEL_GEN_RANGE(e1, 0, e2)
and I liked it.
However I didn't like very much the remaining
INTEL_GEN(dev_priv) < n
and:
INTEL_GEN(e1) < n
INTEL_GEN_RANGE(e1, 0, n - 1)
didn't make much sense either.
So INTEL_GEN use for > or < seems a better unified way for unlimited
bounds. So, no reason to keep GEN_FOREVER here.
Let's kill before someone start using it.
v2: Remove remaining GEN_FOREVER forgotten in a comment. (Daniel)

In order to ensure that our system suspend and resume callbacks are
called in the correct order wrt. those of the HDA driver add a device
link to the HDA driver during audio component binding time. With i915 as
the supplier and HDA as the consumer the PM framework will guarantee
the HDA->i915 suspend (and shutdown) and i915->HDA resume order.
Atm, the lack of this ordering is not a problem, since all the i915
suspend/resume steps that need to be ordered wrt. the HDA driver's
suspend/resume steps are separated out to the i915
suspend_late/resume_early hooks. That will change in a follow-up
patchset where we'll need this ordering guarantee for steps that are in
the i915 suspend/resume hooks (and which can't be moved to
suspend_late/resume_early for other reasons). So this patch is a
preparation for that follow-up patchset.
The change also allows us to move towards removing the i915
suspend_late/resume_early hooks alltogether.
Since we only need to ensure the ordering during suspend/resume and not
during driver probing create the link with DL_FLAG_STATELESS. Since the
probe time ordering has to be optional we use the component framework
for that.
Similarly for runtime PM we depend on the audio driver getting/putting
an i915 runtime PM reference whenever it needs it (along with the proper
i915 display power domain) via the audio component ops get_power /
put_power hooks. So we create the device link without
DL_FLAG_PM_RUNTIME.
v2: (Ville)
- Add a note to the commit message about not using the device link
runtime PM ordering.
- Handle the error return from device_link_add().

The 16Gb DIMM w/a is not applicable to BXT or GLK. Limit it to
the appropriate platforms.
This was especially harsh on GLK since we don't even try to read
the DIMM information on that platforms, hence valid_dimm was
always false and thus we always tried to apply the w/a.
Furthermore the w/a pushed the level 0 latency above the
level 1 latency, which doesn't really make sense.

Now that we implemented support for planar formats on gen11, we can
finally advertise it.
Changes since v1:
- Re-add change to skl_plane_has_planar(), was lost in rebase noise.

The UV plane is the master plane that does all color correction etc.
It needs to be programmed with the dimensions for color plane 1 (UV).
The Y plane just feeds the Y pixels to it. Program the scaler from the
master only, and set PLANE_CTL_YUV420_Y_PLANE on the slave plane.
Changes since v1:
- Make a common skl_program_plane, and use it for both plane updates.
Changes since v2:
- Make color_plane explicit, to clarify skl_update_plane(). (Ville)
