If GuC fails to load, the driver wedges, but in the process it tries to
do stuff that may not be initialized yet. This moves the
xe_gt_tlb_invalidation_init() to be done earlier: as its own doc says,
it's a software-only initialization and should had been named with the
_early() suffix.
Move it to be called by xe_gt_init_early(), so the locks and seqno are
initialized, avoiding a NULL ptr deref when wedging:

The struct device_node *next pointer is not initialized, and it is
used in an error path in which it may have never been modified by
function mtk_drm_of_get_ddp_ep_cid().
Since the error path is relying on that pointer being NULL for the
OVL Adaptor and/or invalid component check and since said pointer
is being used in prints for %pOF, in the case that it points to a
bogus address, the print may cause a KP.
To resolve that, initialize the *next pointer to NULL before usage.

This is a set of squashed commits to facilitate smooth applying to
stable. Each commit message is retained for reference.
1) Allow a GGTT mapped batch to be submitted to user exec queue
For a OA use case, one of the HW registers needs to be modified by
submitting an MI_LOAD_REGISTER_IMM command to the users exec queue, so
that the register is modified in the user's hardware context. In order
to do this a batch that is mapped in GGTT, needs to be submitted to the
user exec queue. Since all user submissions use q->vm and hence PPGTT,
add some plumbing to enable submission of batches mapped in GGTT.
v2: ggtt is zero-initialized, so no need to set it false (Matt Brost)
2) xe/oa: Use MI_LOAD_REGISTER_IMMEDIATE to enable OAR/OAC
To enable OAR/OAC, a bit in RING_CONTEXT_CONTROL needs to be set.
Setting this bit cause the context image size to change and if not done
correct, can cause undesired hangs.
Current code uses a separate exec_queue to modify this bit and is
error-prone. As per HW recommendation, submit MI_LOAD_REGISTER_IMM to
the target hardware context to modify the relevant bit.
In v2 version, an attempt to submit everything to the user-queue was
made, but it failed the unprivileged-single-ctx-counters test. It
appears that the OACTXCONTROL must be modified from a remote context.
In v3 version, all context specific register configurations were moved
to use LOAD_REGISTER_IMMEDIATE and that seems to work well. This is a
cleaner way, since we can now submit all configuration to user
exec_queue and the fence handling is simplified.
v2:
(Matt)
- set job->ggtt to true if create job is successful
- unlock vm on job error
(Ashutosh)
- don't wait on job submission
- use kernel exec queue where possible
v3:
(Ashutosh)
- Fix checkpatch issues
- Remove extra spaces/new-lines
- Add Fixes: and Cc: tags
- Reset context control bit when OA stream is closed
- Submit all config via MI_LOAD_REGISTER_IMMEDIATE
(Umesh)
- Update commit message for v3 experiment
- Squash patches for easier port to stable
v4:
(Ashutosh)
- No need to pass q to xe_oa_submit_bb
- Do not support exec queues with width > 1
- Fix disabling of CTX_CTRL_OAC_CONTEXT_ENABLE
v5:
(Ashutosh)
- Drop reg_lri related comments
- Use XE_OA_SUBMIT_NO_DEPS in xe_oa_load_with_lri

Fix dp mode valid issue to avoid abnormal display of limit state.
After DP passes link training, it can express the lane count of the
current link status is good. Calculate the maximum bandwidth supported
by DP using the current lane count.
The color format will select the best one based on the bandwidth
requirements of the current timing mode. If the current timing mode
uses RGB and meets the DP link bandwidth requirements, RGB will be used.
If the timing mode uses RGB but does not meet the DP link bandwidthi
requirements, it will continue to check whether YUV422 meets
the DP link bandwidth.
FEC overhead is approximately 2.4% from DP 1.4a spec 2.2.1.4.2.
The down-spread amplitude shall either be disabled (0.0%) or up
to 0.5% from 1.4a 3.5.2.6. Add up to approximately 3% total overhead.

mtk_crtc_finish_page_flip() is used to notify userspace that a
page flip has been completed, allowing userspace to free the frame
buffer of the last frame and commit the next frame.
In MediaTek's hardware design for configuring display hardware by using
GCE, `DRM_EVENT_FLIP_COMPLETE` should be notified to userspace after
GCE has finished configuring all display hardware settings for each
atomic_commit().
Currently, mtk_crtc_finish_page_flip() cannot guarantee that GCE has
configured all the display hardware settings of the last frame.
Therefore, to increase the accuracy of the timing for notifying
`DRM_EVENT_FLIP_COMPLETE` to userspace, mtk_crtc_finish_page_flip()
should be moved to ddp_cmdq_cb().

According to spec VDR_CUSTOM_WIDTH register gets programmed after pll
specific VDR registers and TX Lane programming registers are done.
Moreover we only program into C10_VDR_CONTROL1 to update config and
setup master lane once all VDR registers are written into.

Fix a potential GPU page fault during tt -> system moves by waiting for
migration jobs to complete before unmapping SG. This ensures that IOMMU
mappings are not prematurely torn down while a migration job is still in
progress.

Ensure a non-interruptible wait is used when moving a bo to
XE_PL_SYSTEM. This prevents dma_mappings from being removed prematurely
while a GPU job is still in progress, even if the CPU receives a

The host_node pointer was assigned and freed in adv7533_parse_dt(), and
later, adv7533_attach_dsi() uses the same. Fix this use-after-free issue
by dropping of_node_put() in adv7533_parse_dt() and calling of_node_put()
in error path of probe() and also in the remove().

AUDIO_UPDATE bit (Bit 5 of MAIN register 0x4A) needs to be set to 1
while updating Audio InfoFrame information and then set to 0 when done.
Otherwise partially updated Audio InfoFrames could be sent out. Two
cases where this rule were not followed are fixed:
- In adv7511_hdmi_hw_params() make sure AUDIO_UPDATE bit is updated
before/after setting ADV7511_REG_AUDIO_INFOFRAME.
- In audio_startup() use the correct register for clearing
AUDIO_UPDATE bit.
The problem with corrupted audio infoframes were discovered by letting
a HDMI logic analyser check the output of ADV7535.
Note that this patchs replaces writing REG_GC(1) with
REG_INFOFRAME_UPDATE. Bit 5 of REG_GC(1) is positioned within field
GC_PP[3:0] and that field doesn't control audio infoframe and is read-
only. My conclusion therefore was that the author if this code meant to
clear bit 5 of REG_INFOFRAME_UPDATE from the very beginning.

Commit baf4afc5831438 ("drm/sched: Improve teardown documentation")
added a list of drm_sched_fini()'s problems. The list triggers htmldocs
warning (but renders correctly in htmldocs output):
Documentation/gpu/drm-mm:571: ./drivers/gpu/drm/scheduler/sched_main.c:1359: ERROR: Unexpected indentation.
Separate the list from the preceding paragraph by a blank line to fix
the warning. While at it, also end the aforementioned paragraph by a
colon.
