Originally a job was only bound to the queue when we pushed this, but
now that's done in drm_sched_job_init, making that parameter entirely
redundant.
Remove it.
The same applies to the context parameter in
lima_sched_context_queue_task, simplify that too.

It might be good enough on x86 with just READ_ONCE, but the write side
should then at least be WRITE_ONCE because x86 has total store order.
It's definitely not enough on arm.
Fix this proplery, which means
- explain the need for the barrier in both places
- point at the other side in each comment
Also pull out the !sched_list case as the first check, so that the
code flow is clearer.
While at it sprinkle some comments around because it was very
non-obvious to me what's actually going on here and why.
Note that we really need full barriers here, at first I thought
store-release and load-acquire on ->last_scheduled would be enough,
but we actually requiring ordering between that and the queue state.

Originally drm_sched_job_init was the point of no return, after which
drivers really should submit a job. I've split that up, which allows
us to fix this issue pretty easily.
Only thing we have to take care of is to not skip to error paths after
that. Other drivers do this the same for out-fence and similar things.
v2: It's not really a bugfix, just an improvement, since all
drm_sched_job_arm does is reserve the fence number. And gaps should be
fine, as long as the drm_sched_job doesn't escape anywhere at all.
For robustness it's still better to align with other drivers here and
not bail out after job_arm().
v3: I misplaced drm_sched_job_arm by _one_ line! Thanks to Rob for
testing and debug help.

This is a very confusingly named function, because not just does it
init an object, it arms it and provides a point of no return for
pushing a job into the scheduler. It would be nice if that's a bit
clearer in the interface.
But the real reason is that I want to push the dependency tracking
helpers into the scheduler code, and that means drm_sched_job_init
must be called a lot earlier, without arming the job.
v2:
- don't change .gitignore (Steven)
- don't forget v3d (Emma)
v3: Emma noticed that I leak the memory allocated in
drm_sched_job_init if we bail out before the point of no return in
subsequent driver patches. To be able to fix this change
drm_sched_job_cleanup() so it can handle being called both before and
after drm_sched_job_arm().
Also improve the kerneldoc for this.
v4:
- Fix the drm_sched_job_cleanup logic, I inverted the booleans, as
usual (Melissa)
- Christian pointed out that drm_sched_entity_select_rq() also needs
to be moved into drm_sched_job_arm, which made me realize that the
job->id definitely needs to be moved too.
Shuffle things to fit between job_init and job_arm.
v5:
Reshuffle the split between init/arm once more, amdgpu abuses
drm_sched.ready to signal gpu reset failures. Also document this
somewhat. (Christian)
v6:
Rebase on top of the msm drm/sched support. Note that the
drm_sched_job_init() call is completely misplaced, and hence also the
split-out drm_sched_entity_push_job(). I've put in a FIXME which the next
patch will address.
v7: Drop the FIXME in msm, after discussions with Rob I agree it shouldn't
be a problem where it is now.

Add infrastructure to maintain a pending list of HWRM commands awaiting
completion and reduce the scope of the hwrm_cmd_lock mutex so that it
protects only the request mailbox. The mailbox is free to use for one
or more concurrent commands after receiving deferred response events.
For uniformity and completeness, use the same pending list for
collecting completions for commands that respond via a completion ring.
These commands are only used for freeing rings and for IRQ test and
we only support one such command in flight.
Note deferred responses are also only supported on the main channel.
The secondary channel (KONG) does not support deferred responses.

The conversion follows this general pattern for most of the calls:
1. The input message is changed from a stack variable initialized
using bnxt_hwrm_cmd_hdr_init() to a pointer allocated and intialized
using hwrm_req_init().
2. If we don't need to read the firmware response, the hwrm_send_message()
call is replaced with hwrm_req_send().
3. If we need to read the firmware response, the mutex lock is replaced
by hwrm_req_hold() to hold the response. When the response is read, the
mutex unlock is replaced by hwrm_req_drop().
If additional DMA buffers are needed for firmware response data, the
hwrm_req_dma_slice() is used instead of calling dma_alloc_coherent().
Some minor refactoring is also done while doing these conversions.

We currently use the hwrm_cmd_lock to serialize the update of the
firmware's link status response data and the copying of link status data
to the VF. This won't work when we update the firmware message APIs, so
we use the link_lock mutex instead. All link_info data should be
updated under the link_lock mutex. Also add link_lock to functions that
touch link_info in __bnxt_open_nic() and bnxt_probe_phy(). The locking
is probably not strictly necessary during probe, but it's more consistent.

Slices are a mechanism for suballocating DMA mapped regions from the
request buffer. Such regions can be used for indirect command data
instead of creating new mappings with dma_alloc_coherent().
The advantage of using a slice is that the lifetime of the slice is
bound to the request and will be automatically unmapped when the
request is consumed.
A single external region is also supported. This allows for regions
that will not fit inside the spare request buffer space such that
the same API can be used consistently even for larger mappings.

During firmware crash recovery, it is possible for firmware to respond
to stale HWRM commands that have already timed out. Because response
buffers may be reused, any out of sequence responses need to be ignored
and only the matching seq_id should be accepted.
Also, READ_ONCE should be used for the reads from the DMA buffer to
ensure that the necessary loads are scheduled.

This change constitutes a major step towards supporting multiple
firmware commands in flight by maintaining a separate response buffer
for the duration of each request. These firmware commands are also
known as Hardware Resource Manager (HWRM) commands. Using separate
response buffers requires an API change in order for callers to be
able to free the buffer when done.
It is impossible to keep the existing APIs unchanged. The existing
usage for a simple HWRM message request such as the following:
struct input req = {0};
bnxt_hwrm_cmd_hdr_init(bp, &req, REQ_TYPE, -1, -1);
rc = hwrm_send_message(bp, &req, sizeof(req), HWRM_CMD_TIMEOUT);
if (rc)
/* error */
changes to:
struct input *req;
rc = hwrm_req_init(bp, req, REQ_TYPE);
if (rc)
/* error */
rc = hwrm_req_send(bp, req); /* consumes req */
if (rc)
/* error */
The key changes are:
1. The req is no longer allocated on the stack.
2. The caller must call hwrm_req_init() to allocate a req buffer and
check for a valid buffer.
3. The req buffer is automatically released when hwrm_req_send() returns.
4. If the caller wants to check the firmware response, the caller must
call hwrm_req_hold() to take ownership of the response buffer and
release it afterwards using hwrm_req_drop(). The caller is no longer
required to explicitly hold the hwrm_cmd_lock mutex to read the
response.
5. Because the firmware commands and responses all have different sizes,
some safeguards are added to the code.
This patch maintains legacy API compatibiltiy, implementing the old
API in terms of the new. The follow-on patches will convert all
callers to use the new APIs.

The additional response buffer serves no useful purpose. There can
be only one firmware command in flight due to the hwrm_cmd_lock mutex,
which is taken for the entire duration of any command completion,
KONG or otherwise. It is thus safe to share a single DMA buffer.
Removing the code associated with the additional mapping will simplify
matters in the next patch, which allocates response buffers from DMA
pools on a per request basis.

This patch enables the qcom_ipcc driver to be loaded as a
module. IPCC is fairly core to system, so as such it should
never be unloaded. It registers as a mailbox + irq controller
and the irq controller drivers in kernel are not supposed to
be unloaded as they don't have the visibility over the clients
consuming the irqs. Hence adding supress_bind_attrs to disable
bind/unbind via sysfs.

Use kernel-doc struct notation for the mailbox structs to prevent
these kernel-doc warnings:
drivers/mailbox/mailbox-sti.c:39: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
* STi Mailbox device data
drivers/mailbox/mailbox-sti.c:63: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
* STi Mailbox platform specific configuration
drivers/mailbox/mailbox-sti.c:74: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
* STi Mailbox allocated channel information
Also move the field descriptions ahead of the function description as
is expected in kernel-doc. This prevents another kernel-doc warning.

====================
pull-request: wireless-drivers-next-2021-08-29
here's a pull request to net-next tree, more info below. Please let me know if
there are any problems.
wireless-drivers-next patches for v5.15
Second, and most likely last, set of patches for v5.15. Lots of
iwlwifi patches this time, but smaller changes to other drivers as
well. Nothing special standing out.
Major changes:
rtw88
* add quirk to disable pci caps on HP Pavilion 14-ce0xxx
brcmfmac
* Add WPA3 Personal with FT to supported cipher suites
wcn36xx
* allow firmware name to be overridden by DT
iwlwifi
* support scanning hidden 6GHz networks
* support for a new hardware family (Bz)
* support for new firmware API versions
mwifiex
* add reset_d3cold quirk for Surface gen4+ devices
