Most of the changes this time are for the Qualcomm Snapdragon platforms.
There are bug fixes for error handling in Qualcomm icc-bwmon, rpmh-rsc,
ramp_controller and rmtfs driver as well as the AMD tee firmware
driver and a missing initialization in the Arm ff-a firmware driver.
The Qualcomm RPMh and EDAC drivers need some rework to work correctly
on all supported chips.
The DT fixes include:
- i.MX8 fixes for gpio, pinmux and clock settings
- ADS touchscreen gpio polarity settings in several machines
- Address dtb warnings for caches, panel and input-enable
properties on Qualcomm platforms
- Incorrect data on qualcomm platforms fir SA8155P power domains,
SM8550 LLCC, SC7180-lite SDRAM frequencies and SM8550 soundwire.
- Remoteproc firmware paths are corrected for Sony Xperia 10 IV.

In the last step of the EEH recovery process, the EEH driver calls into
bnx2x_io_resume() to re-initialize the NIC hardware via the function
bnx2x_nic_load(). If an error occurs during bnx2x_nic_load(), OS and
hardware resources are released and an error code is returned to the
caller. When called from bnx2x_io_resume(), the return code is ignored
and the network interface is brought up unconditionally. Later attempts
to send a packet via this interface result in a page fault due to a null
pointer reference.
This patch checks the return code of bnx2x_nic_load(), prints an error
message if necessary, and does not enable the interface.

Since this driver used the "global rate limiter" feature of GWCA,
the TX performance of each port was reduced when multiple ports
transmitted frames simultaneously. To improve performance, remove

features of the following:
- "per priority pause" of GWCA
- "global pause" of COMA

When offloading a TC encap action, the action information for the
hardware might not be "ready": if there's currently no neighbour entry
available for the destination address, we can't construct the Ethernet
header to prepend to the packet. In this case, we still offload the
flow rule, but with its action-set-list ID pointing at a "fallback"
action which simply delivers the packet to its default destination (as
though no flow rule had matched), thus allowing software TC to handle
it. Later, when we receive a neighbouring update that allows us to
construct the encap header, the rule will become "ready" and we will
update its action-set-list ID in hardware to point at the actual
offloaded actions.
This patch sets up these fallback ASLs, but does not yet use them.

selftests: mptcp: skip tests not supported by old kernels (part 2)
After a few years of increasing test coverage in the MPTCP selftests, we
realised [1] the last version of the selftests is supposed to run on old
kernels without issues.
Supporting older versions is not that easy for this MPTCP case: these
selftests are often validating the internals by checking packets that
are exchanged, when some MIB counters are incremented after some
actions, how connections are getting opened and closed in some cases,
etc. In other words, it is not limited to the socket interface between
the userspace and the kernelspace.
In addition to that, the current MPTCP selftests run a lot of different
sub-tests but the TAP13 protocol used in the selftests don't support
sub-tests: one failure in sub-tests implies that the whole selftest is
seen as failed at the end because sub-tests are not tracked. It is then
important to skip sub-tests not supported by old kernels.
To minimise the modifications and reduce the complexity to support old
versions, the idea is to look at external signs and skip the whole
selftests or just some sub-tests before starting them. This cannot be
applied in all cases.
This second part focuses on marking different sub-tests as skipped if
some MPTCP features are not supported. A few techniques are used here:
- Before starting some tests:
- Check if a file (sysctl knob) is present: that's what patch 13/14 is
doing for the userspace PM feature.
- Check if a symbol is present in /proc/kallsyms: patch 1/14 adds some
helpers in mptcp_lib.sh to ease its use. Then these helpers are used
in patches 2, 3, 4, 10, 11 and 14/14.
- Set a flag and get the status to check if a feature is supported:
patch 8/14 is doing that with the 'fullmesh' flag.
- After having launched the tests:
- Retrieve the counters after a test and check if they are different
than 0. Similar to the check with the flag, that's not ideal but in
this case, the counters were already present before the introduction
of MPTCP but they have been supported by MPTCP sockets only later.
Patches 5 and 6/14 are using this technique.
Before skipping tests, SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES env var
value is checked: if it is set to 1, the test is marked as "failed"
instead of "skipped". MPTCP public CI expects to have all features
supported and it sets this env var to 1 to catch regressions in these
new checks.
Patches 7/14 and 9/14 are a bit different because they don't skip tests:
- Patch 7/14 retrieves the default values instead of using hardcoded
ones because these default values have been modified at some points.
Then the comparisons are done with the default values.
- patch 9/14 relaxes the expected returned size from MPTCP's getsockopt
because the different structures gathering various info can get new
fields and get bigger over time. We cannot expect that the userspace
is using the same structure as the kernel.

will come soon after in the third part with quite a few patches.

Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
One of them is the new listener events linked to the path-manager
introduced by commit f8c9dfbd875b ("mptcp: add pm listener events").
It is possible to look for "mptcp_event_pm_listener" in kallsyms to know

kernel can returned smaller sizes, e.g. recently the tcp_info structure
has been modified in commit 71fc704768f6 ("tcp: add rcv_wnd and
plb_rehash to TCP_INFO") where a new field has been added.
The userspace can also expect a smaller size if it is compiled with old
uAPI kernel headers.
So for these sizes, we can only check if they are above a certain
threshold, 0 for the moment. We can also only compared sizes with the
ones set by the kernel.

That's not ideal because something could be wrong with the feature and

In case user wants to configure the SFs, for example: to use only vdpa
functionality, he needs to fully probe a SF, configure what he wants,
and afterward reload the SF.
In order to save the time of the reload, local SFs will probe without
any auxiliary sub-device, so that the SFs can be configured prior to
its full probe.
The defaults of the enable_* devlink params of these SFs are set to
false.
Usage example:
Create SF:
$ devlink port add pci/0000:08:00.0 flavour pcisf pfnum 0 sfnum 11
$ devlink port function set pci/0000:08:00.0/32768 \
hw_addr 00:00:00:00:00:11 state active
Enable ETH auxiliary device:
$ devlink dev param set auxiliary/mlx5_core.sf.1 \
name enable_eth value true cmode driverinit
Now, in order to fully probe the SF, use devlink reload:
$ devlink dev reload auxiliary/mlx5_core.sf.1
At this point the user have SF devlink instance with auxiliary device
for the Ethernet functionality only.

mlx5_cmd_init_hca() is taking ~0.2 seconds. In case of a user who
desire to disable some of the SF aux devices, and with large scale-1K
SFs for example, this user will waste more than 3 minutes on
mlx5_cmd_init_hca() which isn't needed at this stage.
Downstream patch will change SFs which are probe over the E-switch,
local SFs, to be probed without any aux dev. In order to support this,
