2023-09-12iio: Add IIO_DELTA_ANGL channel typeRamona Bolboaca4-0/+26
The delta angle is defined as a piece-wise integration of angular velocity data. The delta angle represents the amount of angular displacement between two consecutive measurements and it is measured in radians. In order to track the total angular displacement during a desired period of time, simply sum-up the delta angle samples acquired during that time. IIO currently does not offer a suitable channel type for this type of measurements hence this patch adds it.

2023-09-11iio: frequency: adf4350: Use device managed functions and fix power down issue.Jinjie Ruan1-52/+23
The devm_clk_get_enabled() helper: - calls devm_clk_get() - calls clk_prepare_enable() and registers what is needed in order to call clk_disable_unprepare() when needed, as a managed resource. Also replace devm_regulator_get() and regulator_enable() with devm_regulator_get_enable() helper and remove regulator_disable(). Replace iio_device_register() with devm_iio_device_register() and remove iio_device_unregister(). And st->reg is not used anymore, so remove it. As Jonathan pointed out, couple of things that are wrong: 1) The device is powered down 'before' we unregister it with the subsystem and as such userspace interfaces are still exposed which probably won't do the right thing if the chip is powered down. 2) This isn't done in the error paths in probe. To solve this problem, register a new callback adf4350_power_down() with devm_add_action_or_reset(), to enable software power down in both error and device detach path. So the remove function can be removed. Remove spi_set_drvdata() from the probe function, since spi_get_drvdata() is not used anymore.

2023-09-11staging: iio: Use devm_clk_get_enabled() helper functionJinjie Ruan3-53/+5
The devm_clk_get_enabled() helper: - calls devm_clk_get() - calls clk_prepare_enable() and registers what is needed in order to call clk_disable_unprepare() when needed, as a managed resource. This simplifies the code and avoids the need of a dedicated function used with devm_add_action_or_reset().

Add a device managed hook, via devm_add_action_or_reset() and mt6577_power_off(), to power off on device detach. Replace iio_device_register() by devm_iio_device_register() and remove the mt6577_auxadc_remove() function used to unregister the device and power off the device. Remove platform_set_drvdata() from the probe function, since platform_get_drvdata() is not used anymore. Remove mt6577_auxadc_mod_reg() call from the probe function error path.

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" * tag 'topic/drm-ci-2023-08-31-1' of git://anongit.freedesktop.org/drm/drm: drm: ci: docs: fix build warning - add missing escape drm: Add initial ci/ subdirectory

git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools Pull perf tools updates from Arnaldo Carvalho de Melo: "perf tools maintainership: - Add git information for perf-tools and perf-tools-next trees and 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 trace -a -e *nanosleep,perf* perf stat -e cycles,instructions sleep 5 0.000 ( 9.034 ms): perf/327641 perf_event_open(attr_uptr: { type: 0 (PERF_TYPE_HARDWARE), size: 136, config: 0 (PERF_COUNT_HW_CPU_CYCLES), sample_type: IDENTIFIER, read_format: TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING, disabled: 1, inherit: 1, enable_on_exec: 1, exclude_guest: 1 }, pid: 327642 (perf), cpu: -1, group_fd: -1, flags: FD_CLOEXEC) = 3 9.039 ( 0.006 ms): perf/327641 perf_event_open(attr_uptr: { type: 0 (PERF_TYPE_HARDWARE), size: 136, config: 0x1 (PERF_COUNT_HW_INSTRUCTIONS), sample_type: IDENTIFIER, read_format: TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING, disabled: 1, inherit: 1, enable_on_exec: 1, exclude_guest: 1 }, pid: 327642 (perf-exec), cpu: -1, group_fd: -1, flags: FD_CLOEXEC) = 4 ?

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).
