[Why]
While booting into OS, driver updates DPP/DISP CLKs.
But init clock value is zero which is invalid.
[How]
Get current clocks value to update init clocks.
To avoid underflow.

Prior to sanitizing the GGTT, the only operations allowed in
intel_display_init_nogem() are those to reserve the preallocated (and
active) regions in the GGTT leftover from the BIOS. Trying to allocate a
GGTT vma (such as intel_pin_and_fence_fb_obj during the initial modeset)
may then conflict with other preallocated regions that have not yet been
protected.
Move the initial modesetting from the end of init_nogem to the beginning
of init so that any vma pinning (either framebuffers or DSB, for example),
is after the GGTT is ready to handle it.
This will prevent the DSB object from being destroyed too early:

We treat idling the GT (intel_rps_park) as a downclock event, and reduce
the frequency we intend to restart the GT with. Since the two workloads
are likely related (e.g. a compositor rendering every 16ms), we want to
carry the frequency and load information from across the idling.
However, we do also need to update the frequencies so that workloads
that run for less than 1ms are autotuned by RPS (otherwise we leave
compositors running at max clocks, draining excess power). Conversely,
if we try to run too slowly, the next workload has to run longer. Since
there is a hysteresis in the power graph, below a certain frequency
running a short workload for longer consumes more energy than running it
slightly higher for less time. The exact balance point is unknown
beforehand, but measurements with 30fps media playback indicate that RPe
is a better choice.

As we use a shmemfs file to hold the context state, when not in use it
may be swapped out, such as across suspend. Since we wrote into the
shmemfs without marking the pages as dirty, the contents may be dropped
instead of being written back to swap. On re-using the shmemfs file,
such as creating a new context after resume, the contents of that file
were likely garbage and so the new context could then hang the GPU.
Simply mark the page as being written when copying into the shmemfs
file, and it the new contents will be retained across swapout.

As we funnel more and more contexts into the breadcrumbs on an engine,
the hold time of b->irq_lock grows. As we may then contend with the
b->irq_lock during request submission, this increases the burden upon
the engine->active.lock and so directly impacts both our execution
latency and client latency. If we split the b->irq_lock by introducing a
per-context spinlock to manage the signalers within a context, we then
only need the b->irq_lock for enabling/disabling the interrupt and can
avoid taking the lock for walking the list of contexts within the signal
worker. Even with the current setup, this greatly reduces the number of
times we have to take and fight for b->irq_lock.
Furthermore, this closes the race between enabling the signaling context
while it is in the process of being signaled and removed:

This is caused by virtual engines where although we take the breadcrumb
lock on each of the active engines, they may be different engines on
different requests, It turns out that the b->irq_lock was not a
sufficient proxy for the engine->active.lock in the case of more than
one request, so introduce an explicit lock around ce->signals.
v2: ce->signal_lock is acquired with only RCU protection and so must be
treated carefully and not cleared during reallocation. We also then need
to confirm that the ce we lock is the same as we found in the breadcrumb
list.

Allow a brief period for continued access to a dead intel_context by
deferring the release of the struct until after an RCU grace period.
As we are using a dedicated slab cache for the contexts, we can defer
the release of the slab pages via RCU, with the caveat that individual
structs may be reused from the freelist within an RCU grace period. To
handle that, we have to avoid clearing members of the zombie struct.
This is required for a later patch to handle locking around virtual
requests in the signaler, as those requests may want to move between
engines and be destroyed while we are holding b->irq_lock on a physical
engine.
v2: Drop mutex_reinit(), if we never mark the mutex as destroyed we
don't need to reset the debug code, at the loss of having the mutex
debug code spot us attempting to destroy a locked mutex.
v3: As the intended use will remain strongly referenced counted, with
very little inflight access across reuse, drop the ctor.
v4: Drop the unrequired change to remove the temporary reference around
dropping the active context, and add back some more missing ctor
operations.
v5: The ctor is back. Tvrtko spotted that ce->signal_lock [introduced
later] maybe accessed under RCU and so needs special care not to be
reinitialised.
v6: Don't mix SLAB_TYPESAFE_BY_RCU and RCU list iteration.

Ville noticed that the last mocs entry is used unconditionally by the HW
when it performs cache evictions, and noted that while the value is not
meant to be writable by the driver, we should program it to a reasonable
value nevertheless.
As it turns out, we can change the value of mocs:63 and the value we
were programming into it would cause hard hangs in conjunction with
atomic operations.

The probe routine acquires the reset GPIO using GPIOD_OUT_LOW. Directly
afterwards it calls acx565akm_detect(), which sets the GPIO value to
HIGH. If the bootloader initialized the GPIO to HIGH before the probe
routine was called, there is only a very short time period of a few
instructions where the reset signal is LOW. Exact time depends on
compiler optimizations, kernel configuration and alignment of the stars,
but I expect it to be always way less than 10us. There are no public
datasheets for the panel, but acx565akm_power_on() has a comment with
timings and reset period should be at least 10us. So this potentially
brings the panel into a half-reset state.
The result is, that panel may not work after boot and can get into a
working state by re-enabling it (e.g. by blanking + unblanking), since
that does a clean reset cycle. This bug has recently been hit by Ivaylo
Dimitrov, but there are some older reports which are probably the same
bug. At least Tony Lindgren, Peter Ujfalusi and Jarkko Nikula have
experienced it in 2017 describing the blank/unblank procedure as
possible workaround.
Note, that the bug really goes back in time. It has originally been
introduced in the predecessor of the omapfb driver in commit 3c45d05be382
("OMAPDSS: acx565akm panel: handle gpios in panel driver") in 2012.
That driver eventually got replaced by a newer one, which had the bug
from the beginning in commit 84192742d9c2 ("OMAPDSS: Add Sony ACX565AKM
panel driver") and still exists in fbdev world. That driver has later
been copied to omapdrm and then was used as a basis for this driver.
Last but not least the omapdrm specific driver has been removed in
commit 45f16c82db7e ("drm/omap: displays: Remove unused panel drivers").

In the Rockchip DRM LVDS component driver, the endpoint id provided to
drm_of_find_panel_or_bridge is grabbed from the endpoint's reg property.
However, the property may be missing in the case of a single endpoint.
Initialize the endpoint_id variable to 0 to avoid using an
uninitialized variable in that case.

Pull drm fixes from Dave Airlie:
"Unfortunately this has a bit of thanksgiving stuffing in it, as it a
bit larger (at least the vc4 patches) than I like at this point in
time.
The main thing is it has a bunch of regressions fixes for reports in
the last couple of weeks, ast, nouveau and the amdgpu ttm init fix,
along with the usual selection of amdgpu and i915 fixes.
The vc4 fixes are a few but they are fixes and the nastiest one is a
fix for when you have a 2.4Ghz Wifi and a HDMI signal with a clock in
that range and there isn't enough shielding and interference happen
between the two, the fix adjusts the mode clock to try and avoid the
wifi channels in that case.

should be quieter.

Marc Kleine-Budde says:
====================
pull-request: can 2020-11-27
The first patch is by me and target the gs_usb driver and fixes the endianess
problem with candleLight firmware.
Another patch by me for the mcp251xfd driver add sanity checking to bail out if
no IRQ is configured.
The next three patches target the m_can driver. A patch by me removes the
hardcoded IRQF_TRIGGER_FALLING from the request_threaded_irq() as this clashes
with the trigger level specified in the DT. Further a patch by me fixes the
nominal bitiming tseg2 min value for modern m_can cores. Pankaj Sharma's patch
add support for cores version 3.3.x.
The last patch by Oliver Hartkopp is for af_can and converts a WARN() into a
pr_warn(), which is triggered by the syzkaller. It was able to create a
situation where the closing of a socket runs simultaneously to the notifier
call chain for removing the CAN network device in use.

When setting sk_err, set it to ee_errno, not ee_origin.
Commit f5f99309fa74 ("sock: do not set sk_err in
sock_dequeue_err_skb") disabled updating sk_err on errq dequeue,
which is correct for most error types (origins):
- sk->sk_err = err;
Commit 38b257938ac6 ("sock: reset sk_err when the error queue is
empty") reenabled the behavior for IMCP origins, which do require it:
+ if (icmp_next)

If an msk listener receives an MPJ carrying an invalid token, it
will zero the request socket msk entry. That should later
cause fallback and subflow reset - as per RFC - at
subflow_syn_recv_sock() time due to failing hmac validation.
Since commit 4cf8b7e48a09 ("subflow: introduce and use
mptcp_can_accept_new_subflow()"), we unconditionally dereference
- in mptcp_can_accept_new_subflow - the subflow request msk
before performing hmac validation. In the above scenario we
hit a NULL ptr dereference.
Address the issue doing the hmac validation earlier.

Currently, the openvswitch module is not accepting the correctly formated
netlink message for the TTL decrement action. For both setting and getting
the dec_ttl action, the actions should be nested in the
OVS_DEC_TTL_ATTR_ACTION attribute as mentioned in the openvswitch.h uapi.
When the original patch was sent, it was tested with a private OVS userspace
implementation. This implementation was unfortunately not upstreamed and
reviewed, hence an erroneous version of this patch was sent out.
Leaving the patch as-is would cause problems as the kernel module could
interpret additional attributes as actions and vice-versa, due to the
actions not being encapsulated/nested within the actual attribute, but
being concatinated after it.

Pull arm64 fixes from Will Deacon:
"The main changes are relating to our handling of access/dirty bits,
where our low-level page-table helpers could lead to stale young
mappings and loss of the dirty bit in some cases (the latter has not
been observed in practice, but could happen when clearing "soft-dirty"
if we enabled that). These were posted as part of a larger series, but
the rest of that is less urgent and needs a v2 which I'll get to
shortly.
In other news, we've now got a set of fixes to resolve the
lockdep/tracing problems that have been plaguing us for a while, but
they're still a bit "fresh" and I plan to send them to you next week
after we've got some more confidence in them (although initial CI
results look good).
Summary:
- Fix kerneldoc warnings generated by ACPI IORT code
- Fix pte_accessible() so that access flag is ignored
- Fix missing header #include
- Fix loss of software dirty bit across pte_wrprotect() when HW DBM
is enabled"
