RISC-V Devicetrees for v6.6 Part 2
T-Head:
Add a second minimal devicetree for the second board using the th1520
SoC, the BeagleV Ahead. As with the Lichee Pi 4a, this is sufficient
only for booting to a console, with work on the mmc, clocks and ethernet
sides of things under way. A relicense to a dual licence for the
existing devicetree files is also done, for good measure.

Fix the sort order of some nodes that I resolved incorrectly during a
merge conflict.

Qualcomm driver updates for v6.6
Compatible and clock handling in the Qualcomm SCM driver is cleaned up,
together with a couple stylistic cleanups and transition to mark
exported symbols GPL only.
An abstraction for the RPM subsystem is introduced, to make align the
structure of the SMD and GLINK nodes thereof with the structure when a
remoteproc is involved. This is done to facilitate associating
additional entities with the RPM subsystem.
The qmp_send() API is modified to not expose hardware requirements onto
the client drivers, and then further extended to allow command
formatting directly in the API, to facilitate this typical use case.
In the Qualcomm Command DB driver, NUL characters previously included in
identifiers are dropped from the debugfs, to facilitate scripting.
The thresholds of the BWMON driver are simplified to avoid hard coded
starting values.
The OCMEM driver is updated with some cleanups and fixes, and addition
of MSM8226 support.
PMIC_GLINK gains support for retimer switches, safe mode is selected
when the cable is disconnected from altmode and the same is enabled for
SM8550.
An off-by-one string length check is corrected in the QMI encoder
decoder library.
The RPMh tracepoints are extended to include the state of the request,
to provide needed context in the traced events.
The series from Ulf creating a genpd framework is integrated, to
facilitate the other changes to the cpr, rpmpd and rpmhpd driver.
SDX75 support is added to the rpmhpd driver, and the rpmpd driver is
extended with the same sync_state logic found in the rpmhpd driver.
The socinfo driver gains knowledge about SM4450 and SM7125, the IPQ5019
platform is dropped.
Clock handling in the GSBI driver is cleaned up with the use of
devm_clk_get_enabled().
The list of VMIDs defined for the SCM assign memory interface is
extended.

Merge series from Yang Yingliang <yangyingliang@huawei.com>:
I'm trying to rename the legacy name to modern name used in SPI drivers,
this is part4 patchset.
After introducing devm_spi_alloc_host/spi_alloc_host(), the legacy
named function devm_spi_alloc_master/spi_alloc_master() can be replaced.
And also change other legacy name master/slave to modern name host/target
or controller. Each patch compile test passed.

bpf: Add multi uprobe link
hi,
this patchset is adding support to attach multiple uprobes and usdt probes
through new uprobe_multi link.
The current uprobe is attached through the perf event and attaching many
uprobes takes a lot of time because of that.
The main reason is that we need to install perf event for each probed function
and profile shows perf event installation (perf_install_in_context) as culprit.
The new uprobe_multi link just creates raw uprobes and attaches the bpf
program to them without perf event being involved.
In addition to being faster we also save file descriptors. For the current
uprobe attach we use extra perf event fd for each probed function. The new
link just need one fd that covers all the functions we are attaching to.
v7 changes:
- fixed task release on error path and re-org the error
path to be more straightforward [Yonghong]
- re-organized uprobe_prog_run locking to follow general pattern
and removed might_fault check as it's not needed in uprobe/task
context [Yonghong]
There's support for bpftrace [2] and tetragon [1].

Adding elf symbol iterator object (and some functions) that follow
open-coded iterator pattern and some functions to ease up iterating
elf object symbols.
The idea is to iterate single symbol section with:
struct elf_sym_iter iter;
struct elf_sym *sym;
if (elf_sym_iter_new(&iter, elf, binary_path, SHT_DYNSYM))
goto error;
while ((sym = elf_sym_iter_next(&iter))) {
...
}
I considered opening the elf inside the iterator and iterate all symbol
sections, but then it gets more complicated wrt user checks for when
the next section is processed.
Plus side is the we don't need 'exit' function, because caller/user is
in charge of that.
The returned iterated symbol object from elf_sym_iter_next function
is placed inside the struct elf_sym_iter, so no extra allocation or
argument is needed.

BCMs with an enable_mask expect to only have that specific value written

so happens to be equal to that.
Use the correct value with keepalive voting.

We don't need all the complex arithmetic for BCMs utilizing enable_mask,
as all we need to do is to determine whether there's any user (or

Daniel T. Lee says:
====================
samples/bpf: make BPF programs more libbpf aware
The existing tracing programs have been developed for a considerable
period of time and, as a result, do not properly incorporate the
features of the current libbpf, such as CO-RE. This is evident in
frequent usage of functions like PT_REGS* and the persistence of "hack"
methods using underscore-style bpf_probe_read_kernel from the past.
These programs are far behind the current level of libbpf and can
potentially confuse users.
The kernel has undergone significant changes, and some of these changes
have broken these programs, but on the other hand, more robust APIs have
been developed for increased stableness.
To list some of the kernel changes that this patch set is focusing on,
- symbol mismatch occurs due to compiler optimization [1]
- inline of blk_account_io* breaks BPF kprobe program [2]
- new tracepoints for the block_io_start/done are introduced [3]
- map lookup probes can't be triggered (bpf_disable_instrumentation)[4]
- BPF_KSYSCALL has been introduced to simplify argument fetching [5]
- convert to vmlinux.h and use tp argument structure within it
- make tracing programs to be more CO-RE centric
In this regard, this patch set aims not only to integrate the latest
features of libbpf into BPF programs but also to reduce confusion and
clarify the BPF programs. This will help with the potential confusion
among users and make the programs more intutitive.
