fde5f74ccf platform/x86: thinkpad_acpi: Fix profile mode display in AMT mode
Recently AMT mode was enabled (somewhat unexpectedly) on the Lenovo
Z13 platform. The FW is advertising it is available and the driver tries
to use it - unfortunately it reports the profile mode incorrectly.

Note, there is also some extra work needed to enable the dynamic aspect
of AMT support that I will be following up with; but more testing is
needed first. This patch just fixes things so the profiles are reported
correctly.

6e6eda44b9 sock: add tracepoint for send recv length
Add 2 tracepoints to monitor the tcp/udp traffic
of per process and per cgroup.

Regarding monitoring the tcp/udp traffic of each process, there are two
existing solutions, the first one is https://www.atoptool.nl/netatop.php.
The second is via kprobe/kretprobe.

Netatop solution is implemented by registering the hook function at the
hook point provided by the netfilter framework.

These hook functions may be in the soft interrupt context and cannot
directly obtain the pid. Some data structures are added to bind packets
and processes. For example, struct taskinfobucket, struct taskinfo ...

Every time the process sends and receives packets it needs multiple
hashmaps,resulting in low performance and it has the problem fo inaccurate
tcp/udp traffic statistics(for example: multiple threads share sockets).

We can obtain the information with kretprobe, but as we know, kprobe gets
the result by trappig in an exception, which loses performance compared
to tracepoint.

We compared the performance of tracepoints with the above two methods, and
the results are as follows:

ab -n 1000000 -c 1000 -r http://127.0.0.1/index.html
without trace:
Time per request: 39.660 [ms] (mean)
Time per request: 0.040 [ms] (mean, across all concurrent requests)

netatop:
Time per request: 50.717 [ms] (mean)
Time per request: 0.051 [ms] (mean, across all concurrent requests)

kr:
Time per request: 43.168 [ms] (mean)
Time per request: 0.043 [ms] (mean, across all concurrent requests)

tracepoint:
Time per request: 41.004 [ms] (mean)
Time per request: 0.041 [ms] (mean, across all concurrent requests

It can be seen that tracepoint has better performance.

8e8b6c63cc Merge branch 'rmnet-tx-pkt-aggregation'
Daniele Palmas says:

====================
net: add tx packets aggregation to ethtool and rmnet

Hello maintainers and all,

this patchset implements tx qmap packets aggregation in rmnet and generic
ethtool support for that.

Some low-cat Thread-x based modems are not capable of properly reaching the maximum
allowed throughput both in tx and rx during a bidirectional test if tx packets
aggregation is not enabled.

I verified this problem with rmnet + qmi_wwan by using a MDM9207 Cat. 4 based modem
(50Mbps/150Mbps max throughput). What is actually happening is pictured at
https://drive.google.com/file/d/1gSbozrtd9h0X63i6vdkNpN68d-9sg8f9/view

Testing with iperf TCP, when rx and tx flows are tested singularly there's no issue
in tx and minor issues in rx (not able to reach max throughput). When there are concurrent
tx and rx flows, tx throughput has an huge drop. rx a minor one, but still present.

The same scenario with tx aggregation enabled is pictured at
https://drive.google.com/file/d/1jcVIKNZD7K3lHtwKE5W02mpaloudYYih/view
showing a regular graph.

This issue does not happen with high-cat modems (e.g. SDX20), or at least it
does not happen at the throughputs I'm able to test currently: maybe the same
could happen when moving close to the maximum rates supported by those modems.
Anyway, having the tx aggregation enabled should not hurt.

The first attempt to solve this issue was in qmi_wwan qmap implementation,
see the discussion at https://lore.kernel.org/netdev/20221019132503.6783-1-dnlplm@gmail.com/

However, it turned out that rmnet was a better candidate for the implementation.

Moreover, Greg and Jakub suggested also to use ethtool for the configuration:
not sure if I got their advice right, but this patchset add also generic ethtool
support for tx aggregation.

The patches have been tested mainly against an MDM9207 based modem through USB
and SDX55 through PCI (MHI).

v2 should address the comments highlighted in the review: the implementation is
still in rmnet, due to Subash's request of keeping tx aggregation there.

v3 fixes ethtool-netlink.rst content out of table bounds and a W=1 build warning
for patch 2.

v4 solves a race related to egress_agg_params.

64b5d1f8f2 net: qualcomm: rmnet: add tx packets aggregation
Add tx packets aggregation.

Bidirectional TCP throughput tests through iperf with low-cat
Thread-x based modems revelead performance issues both in tx
and rx.

The Windows driver does not show this issue: inspecting USB
packets revealed that the only notable change is the driver
enabling tx packets aggregation.

Tx packets aggregation is by default disabled and can be enabled
by increasing the value of ETHTOOL_A_COALESCE_TX_MAX_AGGR_FRAMES.

The maximum aggregated size is by default set to a reasonably low
value in order to support the majority of modems.

This implementation is based on patches available in Code Aurora
repositories (msm kernel) whose main authors are

The LKGS instruction atomically loads a segment descriptor into the
%gs descriptor registers, *except* that %gs.base is unchanged, and the
base is instead loaded into MSR_IA32_KERNEL_GS_BASE, which is exactly
what we want this function to do.

acdebd8b4c ALSA: fireface: implement message parser for Fireface 400
This commit implements message parser for Fireface 400 to pass data of
knob control to user space. The parser has FIFO which can store maximum
32 events without no overrun detection since it doesn't matter to lose
the event.

4bdcb8d28f ALSA: fireface: pick up time stamp for request subaction of asynchronous transaction
The time stamp of isochronous cycle at which asynchronous transaction is
sent is perhaps useful somehow. A commit b2405aa948 ("firewire: add
kernel API to access packet structure in request structure for AR context")
adds kernel API to retrieve the time stamp in inner structure of request
subaction.

This commit changes local framework to handle message delivered by the
asynchronous transaction so that time stamp is picked up by the kernel API.

It's cleared that Fireface 400 transmits quadlet message for two purposes
at least; received MIDI messages and notification of knob control
operation. Nevertheless current implementation uses callback function name
just for MIDI messages.

This commit renames the callback functions.
