dt-bindings: soc: loongson,ls2k-pmc: Allow syscon-reboot/syscon-poweroff as child
The reboot and poweroff features are actually part of the Power Management Unit system controller, thus allow them as its children, instead of specifying as separate device nodes with syscon phandle. Without it, the reboot/poweroff feature becomes unavailable.

arm64: dts: imx8mm-evk: Fix hdmi@3d node
The hdmi@3d node's compatible string is "adi,adv7535" instead of
"adi,adv7533" or "adi,adv751*".
Fix the hdmi@3d node by means of:
* Use default register addresses for "cec", "edid" and "packet", because
there is no need to use a non-default address map.
* Add missing interrupt related properties.
* Drop "adi,input-*" properties which are only valid for adv751*.
* Add VDDEXT_3V3 fixed regulator
* Add "*-supply" properties, since most are required.
* Fix label names - s/adv7533/adv7535/.

bus: ti-sysc: Fix SYSC_QUIRK_SWSUP_SIDLE_ACT handling for uart wake-up
The uarts should be tagged with SYSC_QUIRK_SWSUP_SIDLE instead of
SYSC_QUIRK_SWSUP_SIDLE_ACT. The difference is that SYSC_QUIRK_SWSUP_SIDLE
is used to force idle target modules rather than block idle during usage.
The SYSC_QUIRK_SWSUP_SIDLE_ACT should disable autoidle and wake-up when
a target module is active, and configure autoidle and wake-up when a
target module is inactive. We are missing configuring the target module
on sysc_disable_module(), and missing toggling of the wake-up bit.
Let's fix the issue to allow uart wake-up to work.

riscv: dts: starfive: fix NOR flash reserved-data partition size
The Starfive VisionFive 2 has a 16MiB NOR flash, while the reserved-data
partition is declared starting at address 0x600000 with a size of
0x1000000. This causes the kernel to output the following warning:
[ 22.156589] mtd: partition "reserved-data" extends beyond the end of device "13010000.spi.0" -- size truncated to 0xa00000
It seems to be a confusion between the size of the partition and the end
address. Fix that by specifying the right size.

bus: ti-sysc: Use fsleep() instead of usleep_range() in sysc_reset()
The am335x-evm started producing boot errors because of subtle timing
changes:
Unhandled fault: external abort on non-linefetch (0x1008) at 0xf03c1010
...
sysc_reset from sysc_probe+0xf60/0x1514
sysc_probe from platform_probe+0x5c/0xbc
...
The fix consists in using the appropriate sleep function in sysc reset.
For flexible sleeping, fsleep is recommended. Here, sysc delay parameter
can take any value in [0 - 255] us range. As a result, fsleep() should
be used, calling udelay() for a sysc delay lower than 10 us.

Pull drm ci scripts from Dave Airlie:
"This is a bunch of ci integration for the freedesktop gitlab instance
where we currently do upstream userspace testing on diverse sets of
GPU hardware. From my perspective I think it's an experiment worth
going with and seeing how the benefits/noise playout keeping these
files useful.
Ideally I'd like to get this so we can do pre-merge testing on PRs
eventually.
Below is some info from danvet on why we've ended up making the
decision and how we can roll it back if we decide it was a bad plan.
Why in upstream?
- like documentation, testcases, tools CI integration is one of these
things where you can waste endless amounts of time if you
accidentally have a version that doesn't match your source code
- but also like the above, there's a balance, this is the initial cut
of what we think makes sense to keep in sync vs out-of-tree,
probably needs adjustment
- gitlab supports out-of-repo gitlab integration and that's what's
been used for the kernel in drm, but it results in per-driver
fragmentation and lots of duplicated effort. the simple act of
smashing an arbitrary winner into a topic branch already started
surfacing patches on dri-devel and sparking good cross driver team
discussions
Why gitlab?
- it's not any more shit than any of the other CI
- drm userspace uses it extensively for everything in userspace, we
have a lot of people and experience with this, including
integration of hw testing labs
- media userspace like gstreamer is also on gitlab.fd.o, and there's
discussion to extend this to the media subsystem in some fashion
Can this be shared?
- there's definitely a pile of code that could move to scripts/ if
other subsystem adopt ci integration in upstream kernel git. other
bits are more drm/gpu specific like the igt-gpu-tests/tools
integration
- docker images can be run locally or in other CI runners
Will we regret this?
- it's all in one directory, intentionally, for easy deletion
- probably 1-2 years in upstream to see whether this is worth it or a
Big Mistake. that's roughly what it took to _really_ roll out solid
CI in the bigger userspace projects we have on gitlab.fd.o like
mesa3d"

perf tools changes for v6.6:
perf tools maintainership:
- Add git information for perf-tools and perf-tools-next trees/branches to the
MAINTAINERS file. That is where development now takes place and myself and
Namhyung Kim have write access, more people to come as we emulate other
maintainer groups.
perf record:
- Record kernel data maps when 'perf record --data' is used, so that global variables can
be resolved and used in tools that do data profiling.
perf trace:
- Remove the old, experimental support for BPF events in which a .c file was passed as
an event: "perf trace -e hello.c" to then get compiled and loaded.
The only known usage for that, that shipped with the kernel as an example for such events,
augmented the raw_syscalls tracepoints and was converted to a libbpf skeleton, reusing all
the user space components and the BPF code connected to the syscalls.
In the end just the way to glue the BPF part and the user space type beautifiers changed,
now being performed by libbpf skeletons.
The next step is to use BTF to do pretty printing of all syscall types, as discussed with
Alan Maguire and others.
Now, on a perf built with BUILD_BPF_SKEL=1 we get most if not all path/filenames/strings,
some of the networking data structures, perf_event_attr, etc, i.e. systemwide tracing of
nanosleep calls and perf_event_open syscalls while 'perf stat' runs 'sleep' for 5 seconds:

perf annotate:
- Building with binutils' libopcode now is opt-in (BUILD_NONDISTRO=1) for
licensing reasons, and we missed a build test on tools/perf/tests makefile.
Since we now default to NDEBUG=1, we ended up segfaulting when building with
BUILD_NONDISTRO=1 because a needed initialization routine was being "error
checked" via an assert.
Fix it by explicitly checking the result and aborting instead if it fails.
We better back propagate the error, but at least 'perf annotate' on samples
collected for a BPF program is back working when perf is built with
BUILD_NONDISTRO=1.
perf report/top:
- Add back TUI hierarchy mode header, that is seen when using 'perf report/top --hierarchy'.
- Fix the number of entries for 'e' key in the TUI that was preventing navigation of
lines when expanding an entry.
perf report/script:
- Support cross platform register handling, allowing a perf.data file collected
on one architecture to have registers sampled correctly displayed when
analysis tools such as 'perf report' and 'perf script' are used on a different
architecture.
- Fix handling of event attributes in pipe mode, i.e. when one uses:
perf record -o - | perf report -i -
When no perf.data files are used.
- Handle files generated via pipe mode with a version of perf and then read
also via pipe mode with a different version of perf, where the event attr
record may have changed, use the record size field to properly support this
version mismatch.
perf probe:
- Accessing global variables from uprobes isn't supported, make the error
message state that instead of stating that some minimal kernel version is
needed to have that feature. This seems just a tool limitation, the kernel
probably has all that is needed.
perf tests:
- Fix a reference count related leak in the dlfilter v0 API where the result
of a thread__find_symbol_fb() is not matched with an addr_location__exit()
to drop the reference counts of the resolved components (machine, thread, map,
symbol, etc). Add a dlfilter test to make sure that doesn't regresses.
- Lots of fixes for the 'perf test' written in shell script related to problems
found with the shellcheck utility.
- Fixes for 'perf test' shell scripts testing features enabled when perf is
built with BUILD_BPF_SKEL=1, such as 'perf stat' bpf counters.
- Add perf record sample filtering test, things like the following example, that gets
implemented as a BPF filter attached to the event:
# perf record -e task-clock -c 10000 --filter 'ip < 0xffffffff00000000'
- Improve the way the task_analyzer test checks if libtraceevent is linked,
using 'perf version --build-options' instead of the more expensinve
'perf record -e "sched:sched_switch"'.
- Add support for riscv in the mmap-basic test. (This went as well via the RiscV tree, same contents).
libperf:
- Implement riscv mmap support (This went as well via the RiscV tree, same contents).
perf script:
- New tool that converts perf.data files to the firefox profiler format so that one can use
the visualizer at https://profiler.firefox.com/. Done by Anup Sharma as part of this year's
Google Summer of Code.
One can generate the output and upload it to the web interface but Anup also automated
everything:
perf script gecko -F 99 -a sleep 60
- Support syscall name parsing on arm64.
- Print "cgroup" field on the same line as "comm".
perf bench:
- Add new 'uprobe' benchmark to measure the overhead of uprobes with/without
BPF programs attached to it.
- breakpoints are not available on power9, skip that test.
perf stat:
- Add #num_cpus_online literal to be used in 'perf stat' metrics, and add this extra
'perf test' check that exemplifies its purpose:
TEST_ASSERT_VAL("#num_cpus_online",
expr__parse(&num_cpus_online, ctx, "#num_cpus_online") == 0);
TEST_ASSERT_VAL("#num_cpus", expr__parse(&num_cpus, ctx, "#num_cpus") == 0);
TEST_ASSERT_VAL("#num_cpus >= #num_cpus_online", num_cpus >= num_cpus_online);
Miscellaneous:
- Improve tool startup time by lazily reading PMU, JSON, sysfs data.
- Improve error reporting in the parsing of events, passing YYLTYPE to error routines,
so that the output can show were the parsing error was found.
- Add 'perf test' entries to check the parsing of events improvements.
- Fix various leak for things detected by -fsanitize=address, mostly things that would
be freed at tool exit, including:
- Free evsel->filter on the destructor.
- Allow tools to register a thread->priv destructor and use it in 'perf trace'.
- Free evsel->priv in 'perf trace'.
- Free string returned by synthesize_perf_probe_point() when the caller fails
to do all it needs.
- Adjust various compiler options to not consider errors some warnings when
building with broken headers found in things like python, flex, bison, as we
otherwise build with -Werror. Some for gcc, some for clang, some for some
specific version of those, some for some specific version of flex or bison, or
some specific combination of these components, bah.
- Allow customization of clang options for BPF target, this helps building on
gentoo where there are other oddities where BPF targets gets passed some compiler
options intended for the native build, so building with WERROR=0 helps while
these oddities are fixed.
- Dont pass ERR_PTR() values to perf_session__delete() in 'perf top' and 'perf lock',
fixing some segfaults when handling some odd failures.
- Add LTO build option.
- Fix format of unordered lists in the perf docs (tools/perf/Documentation).
- Overhaul the bison files, using constructs such as YYNOMEM.
- Remove unused tokens from the bison .y files.
- Add more comments to various structs.
- A few LoongArch enablement patches.
Vendor events (JSON):
- Add JSON metrics for Yitian 710 DDR (aarch64). Things like:
EventName, BriefDescription
visible_window_limit_reached_rd, "At least one entry in read queue reaches the visible window limit.",
visible_window_limit_reached_wr, "At least one entry in write queue reaches the visible window limit.",
op_is_dqsosc_mpc , "A DQS Oscillator MPC command to DRAM.",
op_is_dqsosc_mrr , "A DQS Oscillator MRR command to DRAM.",
op_is_tcr_mrr , "A Temperature Compensated Refresh(TCR) MRR command to DRAM.",
- Add AmpereOne metrics (aarch64).
- Update N2 and V2 metrics (aarch64) and events using Arm telemetry repo.
- Update scale units and descriptions of common topdown metrics on aarch64. Things like:
- "MetricExpr": "stall_slot_frontend / (#slots * cpu_cycles)",
- "BriefDescription": "Frontend bound L1 topdown metric",
+ "MetricExpr": "100 * (stall_slot_frontend / (#slots * cpu_cycles))",
+ "BriefDescription": "This metric is the percentage of total slots that were stalled due to resource constraints in the frontend of the processor.",
- Update events for intel: meteorlake to 1.04, sapphirerapids to 1.15, Icelake+ metric constraints.
- Update files for the power10 platform.

Since we now default to NDEBUG=1, we ended up segfaulting when
building with BUILD_NONDISTRO=1 because a needed initialization
routine was being "error checked" via an assert.
Fix it by explicitly checking the result and aborting instead if it
fails.
We better back propagate the error, but at least 'perf annotate' on
samples collected for a BPF program is back working when perf is
built with BUILD_NONDISTRO=1.
perf report/top:
- Add back TUI hierarchy mode header, that is seen when using 'perf
report/top --hierarchy'.
- Fix the number of entries for 'e' key in the TUI that was
preventing navigation of lines when expanding an entry.
perf report/script:
- Support cross platform register handling, allowing a perf.data file
collected on one architecture to have registers sampled correctly
displayed when analysis tools such as 'perf report' and 'perf
script' are used on a different architecture.
- Fix handling of event attributes in pipe mode, i.e. when one uses:
perf record -o - | perf report -i -
When no perf.data files are used.
- Handle files generated via pipe mode with a version of perf and
then read also via pipe mode with a different version of perf,
where the event attr record may have changed, use the record size
field to properly support this version mismatch.
perf probe:
- Accessing global variables from uprobes isn't supported, make the
error message state that instead of stating that some minimal
kernel version is needed to have that feature. This seems just a
tool limitation, the kernel probably has all that is needed.
perf tests:
- Fix a reference count related leak in the dlfilter v0 API where the
result of a thread__find_symbol_fb() is not matched with an
addr_location__exit() to drop the reference counts of the resolved
components (machine, thread, map, symbol, etc). Add a dlfilter test
to make sure that doesn't regresses.
- Lots of fixes for the 'perf test' written in shell script related
to problems found with the shellcheck utility.
- Fixes for 'perf test' shell scripts testing features enabled when
perf is built with BUILD_BPF_SKEL=1, such as 'perf stat' bpf
counters.
- Add perf record sample filtering test, things like the following
example, that gets implemented as a BPF filter attached to the
event:
# perf record -e task-clock -c 10000 --filter 'ip < 0xffffffff00000000'
- Improve the way the task_analyzer test checks if libtraceevent is
linked, using 'perf version --build-options' instead of the more
expensinve 'perf record -e "sched:sched_switch"'.
- Add support for riscv in the mmap-basic test. (This went as well
via the RiscV tree, same contents).
libperf:
- Implement riscv mmap support (This went as well via the RiscV tree,
same contents).
perf script:
- New tool that converts perf.data files to the firefox profiler
format so that one can use the visualizer at
https://profiler.firefox.com/. Done by Anup Sharma as part of this
year's Google Summer of Code.
One can generate the output and upload it to the web interface but
Anup also automated everything:
perf script gecko -F 99 -a sleep 60
- Support syscall name parsing on arm64.
- Print "cgroup" field on the same line as "comm".
perf bench:
- Add new 'uprobe' benchmark to measure the overhead of uprobes
with/without BPF programs attached to it.
- breakpoints are not available on power9, skip that test.
perf stat:
- Add #num_cpus_online literal to be used in 'perf stat' metrics, and
add this extra 'perf test' check that exemplifies its purpose:
TEST_ASSERT_VAL("#num_cpus_online",
expr__parse(&num_cpus_online, ctx, "#num_cpus_online") == 0);
TEST_ASSERT_VAL("#num_cpus", expr__parse(&num_cpus, ctx, "#num_cpus") == 0);
TEST_ASSERT_VAL("#num_cpus >= #num_cpus_online", num_cpus >= num_cpus_online);
Miscellaneous:
- Improve tool startup time by lazily reading PMU, JSON, sysfs data.
- Improve error reporting in the parsing of events, passing YYLTYPE
to error routines, so that the output can show were the parsing
error was found.
- Add 'perf test' entries to check the parsing of events
improvements.
- Fix various leak for things detected by -fsanitize=address, mostly
things that would be freed at tool exit, including:
- Free evsel->filter on the destructor.
- Allow tools to register a thread->priv destructor and use it in
'perf trace'.
- Free evsel->priv in 'perf trace'.
- Free string returned by synthesize_perf_probe_point() when the
caller fails to do all it needs.
- Adjust various compiler options to not consider errors some
warnings when building with broken headers found in things like
python, flex, bison, as we otherwise build with -Werror. Some for
gcc, some for clang, some for some specific version of those, some
for some specific version of flex or bison, or some specific
combination of these components, bah.
- Allow customization of clang options for BPF target, this helps
building on gentoo where there are other oddities where BPF targets
gets passed some compiler options intended for the native build, so
building with WERROR=0 helps while these oddities are fixed.
- Dont pass ERR_PTR() values to perf_session__delete() in 'perf top'
and 'perf lock', fixing some segfaults when handling some odd
failures.
- Add LTO build option.
- Fix format of unordered lists in the perf docs
(tools/perf/Documentation)
- Overhaul the bison files, using constructs such as YYNOMEM.
- Remove unused tokens from the bison .y files.
- Add more comments to various structs.
- A few LoongArch enablement patches.
Vendor events (JSON):
- Add JSON metrics for Yitian 710 DDR (aarch64). Things like:
EventName, BriefDescription
visible_window_limit_reached_rd, "At least one entry in read queue reaches the visible window limit.",
visible_window_limit_reached_wr, "At least one entry in write queue reaches the visible window limit.",
op_is_dqsosc_mpc , "A DQS Oscillator MPC command to DRAM.",
op_is_dqsosc_mrr , "A DQS Oscillator MRR command to DRAM.",
op_is_tcr_mrr , "A Temperature Compensated Refresh(TCR) MRR command to DRAM.",
- Add AmpereOne metrics (aarch64).
- Update N2 and V2 metrics (aarch64) and events using Arm telemetry
repo.
- Update scale units and descriptions of common topdown metrics on
aarch64. Things like:
- "MetricExpr": "stall_slot_frontend / (#slots * cpu_cycles)",
- "BriefDescription": "Frontend bound L1 topdown metric",
+ "MetricExpr": "100 * (stall_slot_frontend / (#slots * cpu_cycles))",
+ "BriefDescription": "This metric is the percentage of total slots that were stalled due to resource constraints in the frontend of the processor.",
- Update events for intel: meteorlake to 1.04, sapphirerapids to
1.15, Icelake+ metric constraints.
- Update files for the power10 platform"

iov_iter: Fix iov_iter_extract_pages() with zero-sized entries
iov_iter_extract_pages() doesn't correctly handle skipping over initial
zero-length entries in ITER_KVEC and ITER_BVEC-type iterators.
The problem is that it accidentally reduces maxsize to 0 when it
skipping and thus runs to the end of the array and returns 0.
Fix this by sticking the calculated size-to-copy in a new variable
rather than back in maxsize.

sh: push-switch: Reorder cleanup operations to avoid use-after-free bug
The original code puts flush_work() before timer_shutdown_sync()
in switch_drv_remove(). Although we use flush_work() to stop
the worker, it could be rescheduled in switch_timer(). As a result,
a use-after-free bug can occur. The details are shown below:
(cpu 0) | (cpu 1)
switch_drv_remove() |
flush_work() |
... | switch_timer // timer
| schedule_work(&psw->work)
timer_shutdown_sync() |
... | switch_work_handler // worker
kfree(psw) // free |
| psw->state = 0 // use
This patch puts timer_shutdown_sync() before flush_work() to
mitigate the bugs. As a result, the worker and timer will be
stopped safely before the deallocate operations.
