Kbuild updates for v6.10
- Avoid 'constexpr', which is a keyword in C23
- Allow 'dtbs_check' and 'dt_compatible_check' run independently of
'dt_binding_check'
- Fix weak references to avoid GOT entries in position-independent
code generation
- Convert the last use of 'optional' property in arch/sh/Kconfig
- Remove support for the 'optional' property in Kconfig
- Remove support for Clang's ThinLTO caching, which does not work with
the .incbin directive
- Change the semantics of $(src) so it always points to the source
directory, which fixes Makefile inconsistencies between upstream and
downstream
- Fix 'make tar-pkg' for RISC-V to produce a consistent package
- Provide reasonable default coverage for objtool, sanitizers, and
profilers
- Remove redundant OBJECT_FILES_NON_STANDARD, KASAN_SANITIZE, etc.
- Remove the last use of tristate choice in drivers/rapidio/Kconfig
- Various cleanups and fixes in Kconfig

Specific for timerlat:
- Improves the output of timerlat top by adding a missing \n,
and by avoiding printing color-formatting characters where
they are translated to regular characters.
- Improves timerlat auto-analysis output by replacing '\t'
with spaces to avoid copy-and-paste issues when reporting
problems.
- For timerlat, make the user-space (-u) option the default,
as it is the most complete test. Add a -k option to use
the in-kernel workload.
- On timerlat top and hist, add a summary with the overall
results. For instance, the minimum value for all CPUs,
the overall average and the maximum value from all CPUs.
- timerlat hist was printing initial values (i.e., 0 as max,
and ~0 as min) if the trace stopped before the first Ret-User
event. This problem was fixed by printing the " - "
no value string to the output if that was the case.
For all RTLA tools:
- Add a --warm-up <seconds> option, allowing the workload to
run for <seconds> before starting to collect results.
- Add a --trace-buffer-size option, allowing the user to set
the tracing buffer size for -t option. This option is mainly
useful for reducing the trace file. Now rtla depends on
libtracefs >= 1.6.
- Fix the -t [trace_file] parsing, now it does not require
the '=' before the option parameter, and better handles the
multiple ways a user can pass the trace_file.txt

user-event updates for v6.10:
- Minor update to the user_events interface The ABI of creating a user event states that the fields are separated by semicolons, and spaces should be ignored.

tracing ring buffer updates for v6.10:
- Add ring_buffer memory mappings The tracing ring buffer was created based on being mostly used with the splice system call. It is broken up into page ordered sub-buffers and the reader swaps a new sub-buffer with an existing sub-buffer that's part of the write buffer. It then has total access to the swapped out sub-buffer and can do copyless movements of the memory into other mediums (file system, network, etc). The buffer is great for passing around the ring buffer contents in the kernel, but is not so good for when the consumer is the user space task itself. A new interface is added that allows user space to memory map the ring buffer. It will get all the write sub-buffers as well as reader sub-buffer (that is not written to). It can send an ioctl to change which sub-buffer is the new reader sub-buffer. The ring buffer is read only to user space. It only needs to call the ioctl when it is finished with a sub-buffer and needs a new sub-buffer that the writer will not write over. A self test program was also created for testing and can be used as an example for the interface to user space. The libtracefs (external to the kernel) also has code that interacts with this, although it is disabled until the interface is in a official release. It can be enabled by compiling the library with a special flag. This was used for testing applications that perform better with the buffer being mapped. Memory mapped buffers have limitations. The main one is that it can not be used with the snapshot logic. If the buffer is mapped, snapshots will be disabled. If any logic is set to trigger snapshots on a buffer, that buffer will not be allowed to be mapped. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZkYzDRQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qttNAQCj3I0OpeI1vms85ShIa7Eha2qes5uC Yml2fnapkmRSwAEAp5UTGxtDctycWOk9B9PA7/oJmLgATaQwRKoEeTUwfAA= =TyEB -----END PGP SIGNATURE----- Merge tag 'trace-ringbuffer-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing ring buffer updates from Steven Rostedt: "Add ring_buffer memory mappings.

sysctl changes for v6.10-rc1
Summary
* Removed sentinel elements from ctl_table structs in kernel/*
Removing sentinels in ctl_table arrays reduces the build time size and
runtime memory consumed by ~64 bytes per array. Removals for net/, io_uring/,
mm/, ipc/ and security/ are set to go into mainline through their respective
subsystems making the next release the most likely place where the final
series that removes the check for proc_name == NULL will land. This PR adds
to removals already in arch/, drivers/ and fs/.
* Adjusted ctl_table definitions and references to allow constification
Adjustments:
- Removing unused ctl_table function arguments
- Moving non-const elements from ctl_table to ctl_table_header
- Making ctl_table pointers const in ctl_table_root structure
Making the static ctl_table structs const will increase safety by keeping the
pointers to proc_handler functions in .rodata. Though no ctl_tables where
made const in this PR, the ground work for making that possible has started
with these changes sent by Thomas Weißschuh.
Testing
* These changes went into linux-next after v6.9-rc4; giving it a good month of
testing.

net: dsa: microchip: Correct initialization order for KSZ88x3 ports
Adjust the initialization sequence of KSZ88x3 switches to enable
802.1p priority control on Port 2 before configuring Port 1. This
change ensures the apptrust functionality on Port 1 operates
correctly, as it depends on the priority settings of Port 2. The
prior initialization sequence incorrectly configured Port 1 first,
which could lead to functional discrepancies.

idpf: don't skip over ethtool tcp-data-split setting
Disabling tcp-data-split on idpf silently fails:
# ethtool -G $NETDEV tcp-data-split off
# ethtool -g $NETDEV | grep 'TCP data split'
TCP data split: on
But it works if you also change 'tx' or 'rx':
# ethtool -G $NETDEV tcp-data-split off tx 256
# ethtool -g $NETDEV | grep 'TCP data split'
TCP data split: off
The bug is in idpf_set_ringparam, where it takes a shortcut out if the
TX and RX sizes are not changing. Fix it by checking also if the
tcp-data-split setting remains unchanged. Only then can the soft reset
be skipped.

* MTD
Simon Glass wanted to support binman's output properties in order to
check their validity using the binding checks and proposed changes with
the missing properties as well as a binman compatible.
Krzysztof Kozlowski on his side shared a new yaml for describing
Samsung's OneNAND interface.
The interface with NVMEM has also been slightly improved/fixed,
especially now that OTP are also supported in the NAND subsystem.
Along with these changes, small cleanups have also been contributed
around ID tables, structure sizes, arithmetic checks and comments.
* Raw NAND subsystem
Two small fixes, one in the Hynix vendor code for properly returning an
error which might have been ignored and another in the Davinci driver to
properly synchronize the controller with the gpio domain.
* SPI NOR subsystem
SPI NOR now uses div_u64() instead of div64_u64() in places where the
divisor is 32 bits. Many 32 bit architectures can optimize this variant
better than a full 64 bit divide.

rtla: Documentation: Fix -t, --trace
Move -t, --trace from common_options.rst to
common_osnoise_options.rst and
common_timerlat_options.rst
so that it will appear in the man pages
rtla-timerlat-hist.1
rtla-timerlat-top.1
rtla-osnoise-hist.1
rtla-osnoise-top.1
Remove the equals ('=') sign and add a space.

rtla: Fix -t\--trace[=file]
The -t option has an optional argument.
The usual case is for a short option to be specified without an '='
and for the long version to be specified with an '='
Various forms of this do not work as expected.
For example:
rtla timerlat hist -T50 -tfile.txt
will result in a truncated file name of "ile.txt"
Another example is that the long form without the '=' will result in the
default file name instead of the requested file name.
This patch properly parses the optional argument with and without '='
and with and without spaces for the short form.
This patch was also tested using -t and --trace without providing a file
name both as the last requested option and with a following long and
short option.
For example:
rtla timerlat hist -T50 -t -u
rtla timerlat hist -T50 --trace -u
This fix is applied to both timerlat top and hist
and to osnoise top and hist.
Here is the full testing for rtla timerlat hist.
Before applying the patch
rtla timerlat hist -T50 -t=file.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 -tfile.txt
Truncated file name "ile.txt"
rtla timerlat hist -T50 -t file.txt
Default file name instead of file.txt
rtla timerlat hist -T50 --trace=file.txt
Truncated file name "ile.txt"
rtla timerlat hist -T50 --trace file.txt
Default file name "timerlat_trace.txt" instead of "file.txt"
After applying the patch:
rtla timerlat hist -T50 -t=file.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 -tfile.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 -t file.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 --trace=file.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 --trace file.txt
Works as expected, "file.txt"
In addition the following tests were performed to make sure that
the default file name worked as expected including with trailing
options.
rtla timerlat hist -T50 -t
Works as expected "timerlat_trace.txt"
rtla timerlat hist -T50 --trace
Works as expected "timerlat_trace.txt"
rtla timerlat hist -T50 -t -u
Works as expected "timerlat_trace.txt"
rtla timerlat hist -T50 --trace -u
Works as expected "timerlat_trace.txt"

rtla/timerlat: Fix histogram report when a cpu count is 0
On short runs it is possible to get no samples on a cpu, like this:
# rtla timerlat hist -u -T50
Index IRQ-001 Thr-001 Usr-001 IRQ-002 Thr-002 Usr-002
2 1 0 0 0 0 0
33 0 1 0 0 0 0
36 0 0 1 0 0 0
49 0 0 0 1 0 0
52 0 0 0 0 1 0
over: 0 0 0 0 0 0
count: 1 1 1 1 1 0
min: 2 33 36 49 52 18446744073709551615
avg: 2 33 36 49 52 -
max: 2 33 36 49 52 0
rtla timerlat hit stop tracing
IRQ handler delay: (exit from idle) 48.21 us (91.09 %)
IRQ latency: 49.11 us
Timerlat IRQ duration: 2.17 us (4.09 %)
Blocking thread: 1.01 us (1.90 %)
swapper/2:0 1.01 us
------------------------------------------------------------------------
Thread latency: 52.93 us (100%)
Max timerlat IRQ latency from idle: 49.11 us in cpu 2
Note, the value 18446744073709551615 is the same as ~0.
Fix this by reporting no results for the min, avg and max if the count
is 0.

rtla: Add --trace-buffer-size option
Add the option allow the users to set a different buffer size for the trace. For example, in large systems, the user might be interested on reducing the trace buffer to avoid large tracing files. The buffer size is specified in kB, and it is only affecting the tracing instance. The function trace_set_buffer_size() appears on libtracefs v1.6, so increase the minimum required version on Makefile.config.

powerpc/fadump: Fix section mismatch warning
With some compilers/configs fadump_setup_param_area() isn't inlined into
its caller (which is __init), leading to a section mismatch warning:
WARNING: modpost: vmlinux: section mismatch in reference:
fadump_setup_param_area+0x200 (section: .text.fadump_setup_param_area)
-> memblock_phys_alloc_range (section: .init.text)
Fix it by adding an __init annotation.
