drm/i915: Add YCBCR 4:2:0/4:4:4 support for LSPCON
LSPCON chips can generate YCBCR outputs, if asked nicely :).
In order to generate YCBCR 4:2:0 outputs, a source must:
- send YCBCR 4:4:4 signals to LSPCON
- program color space as 4:2:0 in AVI infoframes
Whereas for YCBCR 4:4:4 outputs, the source must:
- send YCBCR 4:4:4 signals to LSPCON
- program color space as 4:4:4 in AVI infoframes
So for both 4:2:0 as well as 4:4:4 outputs, we are driving the
pipe for YCBCR 4:4:4 output, but AVI infoframe's color space
information indicates LSPCON FW to start scaling down from YCBCR
4:4:4 and generate YCBCR 4:2:0 output. As the scaling is done by
LSPCON device, we need not to reserve a scaler for 4:2:0 outputs.
V2: rebase
V3: Addressed review comments from Ville
- add enum crtc_output_format instead of bool ycbcr420
- use crtc_output_format=4:4:4 for modeset of LSPCON 4:2:0 output
cases in this way we will have YCBCR 4:4:4 framework ready (except
the ABI part)
V4: Added r-b from Maarten (for v3)
Addressed review comments from Ville:
- Do not add a non-atomic state variable to determine lspcon output.
Instead add bool in CRTC state to indicate lspcon based scaling.
V5: Addressed review comments from Ville:
- Change the state bool name from external scaling to something more
relavent.
- Keep the info and adjusted_mode structures const.
- use crtc_state instead of pipe_config.
- Push all the config change into lspcon_ycbcr420_config function.

drm/i915: Check LSPCON vendor OUI
Intel LSPCON chip is provided by 2 vendors:
- Megachips America (MCA)
- Parade technologies (Parade tech)
Its important to know the vendor of this chip, as the address to
write AVI infoframes is different for those two.
This patch reads the vendor OUI signature, and marks into LSPCON
encoder structure for future usages.
This patch also does a small re-arrangement of the code, by moving
lspcon mode change into probe function.

drm/i915: DRM_FORMAT_C8 is not possible with Yf tiling
Function intel_framebuffer_init() checks for the possibilities during
framebuffer creation (addfb ioctl time). It is missing the fact that
the indexed format is not supported with Yf tiling.
It is worth noticing that skl_plane_format_mod_supported() correctly
handles for the C8/Yf combination, but this function runs during
modeset time, so we only reject the combination later.
Ville recently proposed a new IGT test that only uses addfb to assert
supported formats, so that IGT was failing. Add the check so we get
green squares right from the start after Ville merges his test.
Also drive-by fix the missing /* fall through */ in the chunk we
modified by just turning it into a "break;" since IMHO breaks are
easier to read than fall-throughs.

[ 2.980884] ---[ end trace

The cause of this appears to be due to the fact that if there's
pre-existing display state that was set by the BIOS when i915 loads, it
will attempt to perform a modeset before the driver is registered with
userspace. Since this happens before the driver's registered with
userspace, it's connectors are also unregistered and thus-states which
would turn on DPMS on a connector end up getting rejected since the
connector isn't registered.
These bugs managed to get past Intel's CI partially due to the fact it
never ran a full test on my patches for some reason, but also because
all of the tests unload the GPU once before running. Since this bug is
only really triggered when the drivers tries to perform a modeset before
it's been fully registered with userspace when coming from whatever
display configuration the firmware left us with, it likely would never
have been picked up by CI in the first place.
After some discussion with vsyrjala, we decided the best course of
action would be to just move the unregistered connector checks out of
update_connector_routing() and into drm_atomic_set_crtc_for_connector().
The reason for this being that legacy modesetting isn't going to be
expecting failures anywhere (at least this is the case with X), so
ideally we want to ensure that any DPMS changes will still work even on
unregistered connectors. Instead, we now only reject new modesets which
would change the current CRTC assigned to an unregistered connector
unless no new CRTC is being assigned to replace the connector's previous
one.

drm/i915/dp: Link train Fallback on eDP only if fallback link BW can fit panel's native mode
This patch fixes the original commit
c0cfb10d9e1de49 ("drm/i915/edp:
Do not do link training fallback or prune modes on EDP") that causes
a blank screen in case of certain eDP panels (Eg: seen on Dell XPS13 9350)
where first link training fails and a retraining is required by falling
back to lower link rate/lane count.
In case of some panels they advertise higher link rate/lane count
than whats required for supporting the panel's native mode.
But we always link train at highest link rate/lane count for eDP
and if that fails we can still fallback to lower link rate/lane count
as long as the fallback link BW still fits the native mode to avoid
pruning the panel's native mode yet retraining at fallback values
to recover from a blank screen.
v3:
* Add const for fixed_mode (Ville)
v2:
* Send uevent if link failure on eDP unconditionally

Currently, i915 appears to rely on blocking modesets on

disable the CRTC to fail. This is wrong however, since we still want to
allow userspace to disable CRTCs on no-longer-present MSTB ports by
changing the DPMS state to off and this still requires that we retrieve
an encoder.
So, fix this by always returning a valid encoder regardless of the state

impossible when the port has disappeared, since the VCPI slot searching
we try to do in intel_dp_mst_compute_config() will fail with -EINVAL.
Since the only commits we want to allow on no-longer-present MST ports
are ones that shut off display hardware, we already know that no VCPI

However, we're going to need access to intel_connector->mst_port in
order to fixup ->best_encoder() so that it can always return the correct
encoder for an MST port to prevent legacy DPMS prop changes from
failing. This should be safe, so instead keep intel_connector->mst_port

drm/i915: Fix ILK-IVB sprite enable delays
Sprite enable on ILK-IVB may take two frames to complete
when the hardware is in big FIFO mode (LP1+). That is
not entirely great as it means the sprite enable may
actually happen one frame after we've already signalled
flip completion. At the very least crc checks may fail
due to the sprite not yet being visible when we expect it.
We already have code to deal with big FIFO mode when it
comes to the sprite scaling on IVB
(WaCxSRDisabledForSpriteScaling:ivb). Let's extend that
workaround to kick in whenever the sprite is in the process
of being enabled. Also ILK/SNB bspec has some notes to
indicate that we should most likely also do the sprite
scaling w/a on all three platforms, so let's do that as well.
Pretty easy to reproduce on SNB/IVB. ILK has proved more
elusive, but let's trust the spec and include it as well.

we may have to do vblank waits etc. and the other pipe might
not even be enabled here. So let's pass the plane's current crtc to
intel_plane_disable_noatomic() so that it can its job correctly.
To do that semi-cleanly we also have to change the plane readout
to record the plane's visibility into the bitmasks of the crtc
where the plane is currently enabled rather than to the crtc
we want to use for the plane.
One caveat here is that our active_planes bitmask will get confused
if both planes are enabled on the same pipe. Fortunately we can use
plane_mask to reconstruct active_planes sufficiently since
plane_mask still has the same meaning (is the plane visible?)
during readout. We also have to do the same during the initial
plane readout as the second plane could clear the active_planes
bit the first plane had already set.
v2: Rely on fixup_active_planes() to populate active_planes fully (Daniel)
Add Daniel's proposed comment to better document why we do this
Drop the redundant intel_set_plane_visible() call

drm/i915: Restore vblank interrupts earlier
Plane sanitation needs vblank interrupts (on account of CxSR disable).
So let's restore vblank interrupts earlier.
v2: Make it actually build
v3: Add comment to explain why we need this (Daniel)
