It was lately understood that the current mechanism available in the
driver to get SMU firmware info works only on internal SMU builds and
there is a separate way to get all the SMU logging counters (addressed
in the next patch). Hence remove all the smu info shown via debugfs as it
is no more useful.

The protocol to submit a job request to SMU is to wait for
AMD_PMC_REGISTER_RESPONSE to return 1,meaning SMU is ready to take
requests. PMC driver has to make sure that the response code is always
AMD_PMC_RESULT_OK before making any command submissions.
When we submit a message to SMU, we have to wait until it processes
the request. Adding a read_poll_timeout() check as this was missing in
the existing code.
Also, add a mutex to protect amd_pmc_send_cmd() calls to SMU.

The Think-lmi driver was missing pending_reboot support as it wasn't
available from the BIOS. Turns out this is really useful to have from
user space so implementing from a purely SW point of view.
Thanks to Mario Limonciello for guidance on how fwupd would use this.

We skip filling out the pt with scratch entries if the va range covers
the entire pt, since we later have to fill it with the PTEs for the
object pages anyway. However this might leave open a small window where
the PTEs don't point to anything valid for the HW to consume.
When for example using 2M GTT pages this fill_px() showed up as being
quite significant in perf measurements, and ends up being completely
wasted since we ignore the pt and just use the pde directly.
Anyway, currently we have our PTE construction split between alloc and
insert, which is probably slightly iffy nowadays, since the alloc
doesn't actually allocate anything anymore, instead it just sets up the
page directories and points the PTEs at the scratch page. Later when we
do the insert step we re-program the PTEs again. Better might be to
squash the alloc and insert into a single step, then bringing back this
optimisation(along with some others) should be possible.

QCOM IOMMU driver calls bus_set_iommu() for every IOMMU device controller,
what fails for the second and latter IOMMU devices. This is intended and
must be not fatal to the driver registration process. Also the cleanup
path should take care of the runtime PM state, what is missing in the
current patch. Revert relevant changes to the QCOM IOMMU driver until
a proper fix is prepared.

When user calls dmaengine_terminate_sync, the driver will clean up any
remaining descriptors for all the pending or active transfers that had
previously been submitted. However, this might happen whilst the tasklet is
invoking the DMA callback for the last finished transfer, so by the time it
returns and takes over the channel's spinlock, the list of completed
descriptors it was traversing is no longer valid. This leads to a
read-after-free situation.
Fix it by signalling whether a user-triggered termination has happened by
means of a boolean variable.

The conversion to ww mutexes failed to address the fence code which
already returns -EDEADLK when we run out of fences. Ww mutexes on
the other hand treat -EDEADLK as an internal errno value indicating
a need to restart the operation due to a deadlock. So now when the
fence code returns -EDEADLK the higher level code erroneously
restarts everything instead of returning the error to userspace
as is expected.
To remedy this let's switch the fence code to use a different errno
value for this. -ENOBUFS seems like a semi-reasonable unique choice.
Apart from igt the only user of this I could find is sna, and even
there all we do is dump the current fence registers from debugfs
into the X server log. So no user visible functionality is affected.
If we really cared about preserving this we could of course convert
back to -EDEADLK higher up, but doesn't seem like that's worth
the hassle here.
Not quite sure which commit specifically broke this, but I'll
just attribute it to the general gem ww mutex work.

Commit 99ba0ea616aa ("sfc: adjust efx->xdp_tx_queue_count with the real
number of initialized queues") intended to fix a problem caused by a
round up when calculating the number of XDP channels and queues.
However, this was not the real problem. The real problem was that the
number of XDP TX queues had been reduced to half in
commit e26ca4b53582 ("sfc: reduce the number of requested xdp ev queues"),
but the variable xdp_tx_queue_count had remained the same.
Once the correct number of XDP TX queues is created again in the
previous patch of this series, this also can be reverted since the error
doesn't actually exist.
Only in the case that there is a bug in the code we can have different
values in xdp_queue_number and efx->xdp_tx_queue_count. Because of this,
and per Edward Cree's suggestion, I add instead a WARN_ON to catch if it
happens again in the future.
Note that the number of allocated queues can be higher than the number
of used ones due to the round up, as explained in the existing comment
in the code. That's why we also have to stop increasing xdp_queue_number
beyond efx->xdp_tx_queue_count.

Fixes: e26ca4b53582 sfc: reduce the number of requested xdp ev queues
The buggy commit intended to allocate less channels for XDP in order to
be more unlikely to reach the limit of 32 channels of the driver.
The idea was to use each IRQ/eventqeue for more XDP TX queues than
before, calculating which is the maximum number of TX queues that one
event queue can handle. For example, in EF10 each event queue could
handle up to 8 queues, better than the 4 they were handling before the
change. This way, it would have to allocate half of channels than before
for XDP TX.
The problem is that the TX queues are also contained inside the channel
structs, and there are only 4 queues per channel. Reducing the number of
channels means also reducing the number of queues, resulting in not
having the desired number of 1 queue per CPU.
This leads to getting errors on XDP_TX and XDP_REDIRECT if they're
executed from a high numbered CPU, because there only exist queues for
the low half of CPUs, actually. If XDP_TX/REDIRECT is executed in a low
numbered CPU, the error doesn't happen. This is the error in the logs
(repeated many times, even rate limited):
sfc 0000:5e:00.0 ens3f0np0: XDP TX failed (-22)
This errors happens in function efx_xdp_tx_buffers, where it expects to
have a dedicated XDP TX queue per CPU.
Reverting the change makes again more likely to reach the limit of 32
channels in machines with many CPUs. If this happen, no XDP_TX/REDIRECT
will be possible at all, and we will have this log error messages:
At interface probe:
sfc 0000:5e:00.0: Insufficient resources for 12 XDP event queues (24 other channels, max 32)
At every subsequent XDP_TX/REDIRECT failure, rate limited:
sfc 0000:5e:00.0 ens3f0np0: XDP TX failed (-22)
However, without reverting the change, it makes the user to think that
everything is OK at probe time, but later it fails in an unpredictable
way, depending on the CPU that handles the packet.
It is better to restore the predictable behaviour. If the user sees the
error message at probe time, he/she can try to configure the best way it
fits his/her needs. At least, he/she will have 2 options:
- Accept that XDP_TX/REDIRECT is not available (he/she may not need it)
- Load sfc module with modparam 'rss_cpus' with a lower number, thus
creating less normal RX queues/channels, letting more free resources
for XDP, with some performance penalty.
Anyway, let the calculation of maximum TX queues that can be handled by
a single event queue, and use it only if it's less than the number of TX
queues per channel. This doesn't happen in practice, but could happen if
some constant values are tweaked in the future, such us
EFX_MAX_TXQ_PER_CHANNEL, EFX_MAX_EVQ_SIZE or EFX_MAX_DMAQ_SIZE.

In May 2019 when commit 640f763f98c2 ("net: dsa: sja1105: Add support
for Spanning Tree Protocol") was introduced, the comment that "STP does
not get called for the CPU port" was true. This changed after commit
0394a63acfe2 ("net: dsa: enable and disable all ports") in August 2019
and went largely unnoticed, because the sja1105_bridge_stp_state_set()
method did nothing different compared to the static setup done by
sja1105_init_mac_settings().
With the ability to turn address learning off introduced by the blamed
commit, there is a new priv->learn_ena port mask in the driver. When
sja1105_bridge_stp_state_set() gets called and we are in
BR_STATE_LEARNING or later, address learning is enabled or not depending
on priv->learn_ena & BIT(port).
So what happens is that priv->learn_ena is not being set from anywhere
for the CPU port, and the static configuration done by
sja1105_init_mac_settings() is being overwritten.
To solve this, acknowledge that the static configuration of STP state is
no longer necessary because the STP state is being set by the DSA core
now, but what is necessary is to set priv->learn_ena for the CPU port.

The thunk needs to mmap all BOs for CPU access to allow the debugger to
access them. Invisible ones are mapped with PROT_NONE.

[Why]
The original logic is to update eDP's backlight level
on every amdgpu dm atomic commit, which causes excessive
DMUB write. As a result, when playing game or moving window
around, DMUB timeout and system lagging are observed.
[How]
We only need to update eDP's backlight level when current level
doesn't match requested level.

Since there's nothing special in smu implementation for yellow carp,
it's better to reuse the common smu_v13_0 interfaces and drop the
specific smu_v13_0_1.c|h files.
v2: remove the duplicate register offset and shift mask header files as
well.

[Why]
We're only treating TMDS as a valid target for infoframe updates which
results in PSR being unable to transition from state 4 to state 5.
[How]
Also allow infoframe updates for DCN3.1 - following how we handle
this path for earlier ASIC as well.

In amdgpu_ras_query_error_count() return an error
if the device doesn't support RAS. This prevents
that function from having to always set the values
of the integer pointers (if set), and thus
prevents function side effects--always to have to
set values of integers if integer pointers set,
regardless of whether RAS is supported or
not--with this change this side effect is
mitigated.
Also, if no pointers are set, don't count, since
we've no way of reporting the counts.
Also, give this function a kernel-doc.
