In macro definitions, parentheses are unnecessary in some cases,
such as the calling parameter of a function, the left variable
of the equal sign, and so on. So remove these unnecessary

In vsock_shutdown() we touched some socket fields without holding the
socket lock, such as 'state' and 'sk_flags'.
Also, after the introduction of multi-transport, we are accessing
'vsk->transport' in vsock_send_shutdown() without holding the lock
and this call can be made while the connection is in progress, so
the transport can change in the meantime.
To avoid issues, we hold the socket lock when we enter in
vsock_shutdown() and release it when we leave.
Among the transports that implement the 'shutdown' callback, only
hyperv_transport acquired the lock. Since the caller now holds it,
we no longer take it.

Wei Wang says:
====================
implement kthread based napi polle
The idea of moving the napi poll process out of softirq context to a
kernel thread based context is not new.
Paolo Abeni and Hannes Frederic Sowa have proposed patches to move napi
poll to kthread back in 2016. And Felix Fietkau has also proposed
patches of similar ideas to use workqueue to process napi poll just a
few weeks ago.
The main reason we'd like to push forward with this idea is that the
scheduler has poor visibility into cpu cycles spent in softirq context,
and is not able to make optimal scheduling decisions of the user threads.
For example, we see in one of the application benchmark where network
load is high, the CPUs handling network softirqs has ~80% cpu util. And
user threads are still scheduled on those CPUs, despite other more idle
cpus available in the system. And we see very high tail latencies. In this
case, we have to explicitly pin away user threads from the CPUs handling
network softirqs to ensure good performance.
With napi poll moved to kthread, scheduler is in charge of scheduling both
the kthreads handling network load, and the user threads, and is able to
make better decisions. In the previous benchmark, if we do this and we
pin the kthreads processing napi poll to specific CPUs, scheduler is
able to schedule user threads away from these CPUs automatically.
And the reason we prefer 1 kthread per napi, instead of 1 workqueue
entity per host, is that kthread is more configurable than workqueue,
and we could leverage existing tuning tools for threads, like taskset,
chrt, etc to tune scheduling class and cpu set, etc. Another reason is
if we eventually want to provide busy poll feature using kernel threads
for napi poll, kthread seems to be more suitable than workqueue.
Furthermore, for large platforms with 2 NICs attached to 2 sockets,
kthread is more flexible to be pinned to different sets of CPUs.
In this patch series, I revived Paolo and Hannes's patch in 2016 and
made modifications. Then there are changes proposed by Felix, Jakub,
Paolo and myself on top of those, with suggestions from Eric Dumazet.
In terms of performance, I ran tcp_rr tests with 1000 flows with
various request/response sizes, with RFS/RPS disabled, and compared
performance between softirq vs kthread vs workqueue (patchset proposed
by Felix Fietkau).
Host has 56 hyper threads and 100Gbps nic, 8 rx queues and only 1 numa
node. All threads are unpinned.
req/resp QPS 50%tile 90%tile 99%tile 99.9%tile
softirq 1B/1B 2.75M 337us 376us 1.04ms 3.69ms
kthread 1B/1B 2.67M 371us 408us 455us 550us
workq 1B/1B 2.56M 384us 435us 673us 822us
softirq 5KB/5KB 1.46M 678us 750us 969us 2.78ms
kthread 5KB/5KB 1.44M 695us 789us 891us 1.06ms
workq 5KB/5KB 1.34M 720us 905us 1.06ms 1.57ms
softirq 1MB/1MB 11.0K 79ms 166ms 306ms 630ms
kthread 1MB/1MB 11.0K 75ms 177ms 303ms 596ms
workq 1MB/1MB 11.0K 79ms 180ms 303ms 587ms
When running workqueue implementation, I found the number of threads
used is usually twice as much as kthread implementation. This probably
introduces higher scheduling cost, which results in higher tail
latencies in most cases.
I also ran an application benchmark, which performs fixed qps remote SSD
read/write operations, with various sizes. Again, both with RFS/RPS
disabled.
The result is as follows:
op_size QPS 50%tile 95%tile 99%tile 99.9%tile
softirq 4K 572.6K 385us 1.5ms 3.16ms 6.41ms
kthread 4K 572.6K 390us 803us 2.21ms 6.83ms
workq 4k 572.6K 384us 763us 3.12ms 6.87ms
softirq 64K 157.9K 736us 1.17ms 3.40ms 13.75ms
kthread 64K 157.9K 745us 1.23ms 2.76ms 9.87ms
workq 64K 157.9K 746us 1.23ms 2.76ms 9.96ms
softirq 1M 10.98K 2.03ms 3.10ms 3.7ms 11.56ms
kthread 1M 10.98K 2.13ms 3.21ms 4.02ms 13.3ms
workq 1M 10.98K 2.13ms 3.20ms 3.99ms 14.12ms
In this set of tests, the latency is predominant by the SSD operation.
Also, the user threads are much busier compared to tcp_rr tests. We have
to pin the kthreads/workqueue threads to limit to a few CPUs, to not
disturb user threads, and provide some isolation.
Changes since v9:
Small change in napi_poll() in patch 1.
Split napi_kthread_stop() functionality to add separately in
napi_disable() and netif_napi_del() in patch 2.
Add description for napi_set_threaded() and return dev->threaded when
dev->napi_list is empty for threaded sysfs in patch 3.
Changes since v8:
Added description for threaded param in struct net_device in patch 2.
Changes since v7:
Break napi_set_threaded() into 2 parts, one to create kthread called
from netif_napi_add(), the other to set threaded bit in napi_enable(),
to get rid of inconsistency through all napi in 1 dev.
Added documentation for /sys/class/net/<dev>/threaded.
Changes since v6:
Added memory barrier in napi_set_threaded().
Changed /sys/class/net/<dev>/thread to a ternary value.
Change dev->threaded to a bit instead of bool.
Changes since v5:
Removed ASSERT_RTNL() from napi_set_threaded() and removed rtnl_lock()
operation from napi_enable().
Changes since v4:
Recorded the threaded setting in dev and restore it in napi_enable().
Changes since v3:
Merged and rearranged patches in a logical order for easier review.
Changed sysfs control to be per device.
Changes since v2:
Corrected typo in patch 1, and updated the cover letter with more
detailed and updated test results.
Changes since v1:
Replaced kthread_create() with kthread_run() in patch 5 as suggested by
Felix Fietkau.
Changes since RFC:
Renamed the kthreads to be napi/<dev>-<napi_id> in patch 5 as suggested
by Hannes Frederic Sowa.

This patch adds a new sysfs attribute to the network device class.
Said attribute provides a per-device control to enable/disable the
threaded mode for all the napi instances of the given network device,
without the need for a device up/down.
User sets it to 1 or 0 to enable or disable threaded mode.
Note: when switching between threaded and the current softirq based mode
for a napi instance, it will not immediately take effect if the napi is
currently being polled. The mode switch will happen for the next time
napi_schedule() is called.

This patch allows running each napi poll loop inside its own
kernel thread.
The kthread is created during netif_napi_add() if dev->threaded
is set. And threaded mode is enabled in napi_enable(). We will
provide a way to set dev->threaded and enable threaded mode
without a device up/down in the following patch.
Once that threaded mode is enabled and the kthread is
started, napi_schedule() will wake-up such thread instead
of scheduling the softirq.
The threaded poll loop behaves quite likely the net_rx_action,
but it does not have to manipulate local irqs and uses
an explicit scheduling point based on netdev_budget.

This commit introduces a new function __napi_poll() which does the main
logic of the existing napi_poll() function, and will be called by other
functions in later commits.
This idea and implementation is done by Felix Fietkau <nbd@nbd.name> and
is proposed as part of the patch to move napi work to work_queue
context.
This commit by itself is a code restructure.

the compatible strings are a mess with vendor prefixes not being used

I dropped the 'm25p.*-nonjedec' compatible strings as these don't appear

This patch is to make the error log more clear for fine grain tuning
function, it covers Raven/Raven2/Picasso/Renoir/Vangogh.
The fine grain tuning function uses the sysfs file -- pp_od_clk_voltage,
but only when another sysfs file -- power_dpm_force_performance_level is
switched to "manual" mode, it is allowed to access "pp_od_clk_voltage".

It is possible for ret_vsnprintf to be assigned negative value in
error cases. As an unsigned variable, negative values which
are stored in their 2's complement form gets treated as a positive
number. This will led to treating bad cases as good ones.
eg: -1 gets stored as 0xFFFFFFFF on a 32 bit system

[WHY]
Virtual displays do not use the backend of the pipe, and so have
infinite backend bandwidth.
[HOW]
Add a skip_dio_check bool to the VBA struct, which is used to override
the DIOSupport calculations.

[Why]
Since dmub_rb_cmds are not initialized to 0,
the header is filled with invalid data.
This is causing issues on the fw side.
[How]
Initialize dmub_rb_cmd unions to 0.

[Why]
Current implementation of mod_hdcp_hdcp2_validate_ake_cert()
does not process HDCP status message
TA_HDCP2_MSG_AUTHENTICATION_STATUS__SIGNATURE_CERTIFICAT_ERROR.
As a result, when there is a signature certificate error,
mod_hdcp_hdcp2_validate_ake_cert would return the default status,
which is success.
[How]
For all messages other than TA_HDCP2_MSG_AUTHENTICATION_STATUS__SUCCESS
and TA_HDCP2_MSG_AUTHENTICATION_STATUS__RECEIVERID_REVOKED, return status
as failure.
