drm/i915/fb: Fix rounding error in subsampled plane size calculation
For NV12 FBs with odd main surface tile-row height the CCS surface
height was incorrectly calculated 1 less than the actual value. Fix this
by rounding up the result of divison. For consistency do the same for
the CCS surface width calculation.

drm/i915/hdmi: Turn DP++ TMDS output buffers back on in encoder->shutdown()
Looks like our VBIOS/GOP generally fail to turn the DP dual mode adater
TMDS output buffers back on after a reboot. This leads to a black screen
after reboot if we turned the TMDS output buffers off prior to reboot.
And if i915 decides to do a fastboot the black screen will persist even
after i915 takes over.
Apparently this has been a problem ever since commit
b2ccb822d376 ("drm/i915:
Enable/disable TMDS output buffers in DP++ adaptor as needed") if one
rebooted while the display was turned off. And things became worse with
commit
fe0f1e3bfdfe ("drm/i915: Shut down displays gracefully on reboot")
since now we always turn the display off before a reboot.
This was reported on a RKL, but I confirmed the same behaviour on my
SNB as well. So looks pretty universal.
Let's fix this by explicitly turning the TMDS output buffers back on
in the encoder->shutdown() hook. Note that this gets called after irqs
have been disabled, so the i2c communication with the DP dual mode
adapter has to be performed via polling (which the gmbus code is
perfectly happy to do for us).
We also need a bit of care in handling DDI encoders which may or may
not be set up for HDMI output. Specifically ddc_pin will not be
populated for a DP only DDI encoder, in which case we don't want to
call intel_gmbus_get_adapter(). We can handle that by simply doing
the dual mode adapter type check before calling
intel_gmbus_get_adapter().

drm/i915: Fix type1 DVI DP dual mode adapter heuristic for modern platforms
Looks like we never updated intel_bios_is_port_dp_dual_mode() when
the VBT port mapping became erratic on modern platforms. This
is causing us to look up the wrong child device and thus throwing
the heuristic off (ie. we might end looking at a child device for
a genuine DP++ port when we were supposed to look at one for a
native HDMI port).
Fix it up by not using the outdated port_mapping[] in
intel_bios_is_port_dp_dual_mode() and rely on
intel_bios_encoder_data_lookup() instead.

It's not graceful, instead it leads to boot time warning splats in the
case it is supposed to handle gracefully. Apparently the BIOS/GOP
enabling the port we end up skipping leads to state readout
problems. Back to the drawing board.

drm/i915/dp: Ensure max link params are always valid
Atm until the DPCD for a connector is read the max link rate and lane
count params are invalid. If the connector is modeset, in
intel_dp_compute_config(), intel_dp_common_len_rate_limit(max_link_rate)
will return 0, leading to a intel_dp->common_rates[-1] access.
Fix the above by making sure the max link params are always valid.
The above access leads to an undefined behaviour by definition, though
not causing a user visible problem to my best knowledge, see the previous
patch why. Nevertheless it is an undefined behaviour and it triggers a
BUG() in CONFIG_UBSAN builds, hence CC:stable.

drm/i915/dp: Ensure sink rate values are always valid
Atm, there are no sink rate values set for DP (vs. eDP) sinks until the
DPCD capabilities are successfully read from the sink. During this time
intel_dp->num_common_rates is 0 which can lead to a
intel_dp->common_rates[-1] (*)
access, which is an undefined behaviour, in the following cases:
- In intel_dp_sync_state(), if the encoder is enabled without a sink
connected to the encoder's connector (BIOS enabled a monitor, but the
user unplugged the monitor until the driver loaded).
- In intel_dp_sync_state() if the encoder is enabled with a sink
connected, but for some reason the DPCD read has failed.
- In intel_dp_compute_link_config() if modesetting a connector without
a sink connected on it.
- In intel_dp_compute_link_config() if modesetting a connector with a
a sink connected on it, but before probing the connector first.
To avoid the (*) access in all the above cases, make sure that the sink
rate table - and hence the common rate table - is always valid, by
setting a default minimum sink rate when registering the connector
before anything could use it.
I also considered setting all the DP link rates by default, so that
modesetting with higher resolution modes also succeeds in the last two
cases above. However in case a sink is not connected that would stop
working after the first modeset, due to the LT fallback logic. So this
would need more work, beyond the scope of this fix.
As I mentioned in the previous patch, I don't think the issue this patch
fixes is user visible, however it is an undefined behaviour by
definition and triggers a BUG() in CONFIG_UBSAN builds, hence CC:stable.
v2: Clear the default sink rates, before initializing these for eDP.

amd/display: remove ChromeOS workaround

ddab8bd788f5 ("drm/amd/display: Fix two cursor duplication
when using overlay") and
e7d9560aeae5 ("Revert "drm/amd/display: Fix overlay
validation by considering cursors"").
tl;dr ChromeOS uses the atomic interface for everything except the cursor. This
is incorrect and forces amdgpu to disable some hardware features. Let's revert
the ChromeOS-specific workaround in mainline and allow the Chrome team to keep
it internally in their own tree.
See [1] for more details. This patch is an alternative to [2], which added
ChromeOS detection.

Normally such objects are marked with __I915_MADV_PURGED, which can't be

this is not true, since the madv hint is reset for our special volatile
objects, such that we can re-acquire new pages, if so desired, without

drm/i915: Convert unconditional clflush to drm_clflush_virt_range()
This one is apparently a "clflush for good measure", so bit more
justification (if you can call it that) than some of the others.
Convert to drm_clflush_virt_range() again so that machines without
clflush will survive the ordeal.

drm/i915: Replace the unconditional clflush with drm_clflush_virt_range()
Not all machines have clflush, so don't go assuming they do.
Not really sure why the clflush is even here since hwsp
is supposed to get snooped I thought.
Although in my case we're talking about a i830 machine where
render/blitter snooping is definitely busted. But it might
work for the hswp perhaps. Haven't really reverse engineered
that one fully.

drm/i915/guc: Handle errors in multi-lrc requests
If an error occurs in the front end when multi-lrc requests are getting
generated we need to skip these in the backend but we still need to
emit the breadcrumbs seqno. An issues arises because with multi-lrc
breadcrumbs there is a handshake between the parent and children to make
forward progress. If all the requests are not present this handshake
doesn't work. To work around this, if multi-lrc request has an error we
skip the handshake but still emit the breadcrumbs seqno.

drm/i915: Multi-BB execbuf
Allow multiple batch buffers to be submitted in a single execbuf IOCTL
after a context has been configured with the 'set_parallel' extension.
The number batches is implicit based on the contexts configuration.
This is implemented with a series of loops. First a loop is used to find
all the batches, a loop to pin all the HW contexts, a loop to create all
the requests, a loop to submit (emit BB start, etc...) all the requests,
a loop to tie the requests to the VMAs they touch, and finally a loop to
commit the requests to the backend.
A composite fence is also created for the generated requests to return
to the user and to stick in dma resv slots.
No behavior from the existing IOCTL should be changed aside from when
throttling because the ring for a context is full. In this situation,
i915 will now wait while holding the object locks. This change was done
because the code is much simpler to wait while holding the locks and we
believe there isn't a huge benefit of dropping these locks. If this
proves false we can restructure the code to drop the locks during the
wait.

drm/i915/guc: Implement no mid batch preemption for multi-lrc
For some users of multi-lrc, e.g. split frame, it isn't safe to preempt
mid BB. To safely enable preemption at the BB boundary, a handshake
between parent and child is needed, syncing the set of BBs at the
beginning and end of each batch. This is implemented via custom
emit_bb_start & emit_fini_breadcrumb functions and enabled by default if
a context is configured by set parallel extension.
Lastly, this patch updates the process descriptor to the correct size as
the memory used in the handshake is directly after the process
descriptor.
