Pull parisc architecture fixes from Helge Deller: "This mostly handles oddities with the serial port 8250_gsc.c driver. Although the name suggests it's just for serial ports on the GSC bus (e.g. in older PA-RISC machines), it handles serial ports on PA-RISC PCI devices (e.g. on the SuperIO chip) as well. Thus this renames the driver to 8250_parisc and fixes the config dependencies. The other change is a cleanup on how the device IDs of devices in a PA-RISC machine are shown at startup" * tag 'parisc-for-6.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Avoid printing the hardware path twice parisc: Export iosapic_serial_irq() symbol for serial port driver MAINTAINERS: adjust entry after renaming parisc serial driver parisc: Use signed char for hardware path in pdc.h parisc/serial: Rename 8250_gsc.c to 8250_parisc.c parisc: Make 8250_gsc driver dependend on CONFIG_PARISC

2022-10-28MAINTAINERS: Change myself to a maintainerMatti Vaittinen1-2/+2
After some off-list discussion with Marek Vasut and Geert Uytterhoeven and finally a kx022a driver related discussion with Joe Perches https://lore.kernel.org/lkml/92c3f72e60bc99bf4a21da259b4d78c1bdca447d.camel@perches.com/ it seems that my status as a reviewer has been wrong. I do look after the ROHM/Kionix drivers I've authored and currently I am also paid to do so as is reflected by the 'S: Supported'. According to Joe, the reviewer entry in MAINTAINERS do not indicate such level of support and having a reviewer supporting an IC is a contradiction. Switch undersigned from a reviewer to a maintainer for IC drivers I am taking care of.

Previous commit resolves a WARN splat that can be difficult to reproduce, but with the ovs-dpctl.py utility, it can be trivial. Introduce a test case which creates a DP, and then downgrades the feature set. This will include a utility 'ovs-dpctl.py' that can be extended to do additional tests and diagnostics.

Kernel enablement went thru the tip tree. - Fix 'perf probe' error log check in 'perf test' when no debuginfo is available. - Fix 'perf stat' aggregation mode logic, it should be looking at the CPU not at the core number. - Fix flags parsing in 'perf trace' filters. - Introduce compact encoding of CPU range encoding on perf.data, to avoid having a bitmap with all the CPUs. - Improvements to the 'perf stat' metrics, including adding "core_wide", and computing "smt" from the CPU topology. - Add support to the new PERF_FORMAT_LOST perf_event_attr.read_format, that allows tooling to ask for the precise number of lost samples for a given event. - Add 'addr' sort key to see just the address of sampled instructions: $ perf record -o- true | perf report -i- -s addr [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.000 MB - ] # Samples: 12 of event 'cycles:u' # Event count (approx.): 252512 # # Overhead Address # ........ .................. 42.96% 0x7f96f08443d7 29.55% 0x7f96f0859b50 14.76% 0x7f96f0852e02 8.30% 0x7f96f0855028 4.43% 0xffffffff8de01087 perf annotate: Toggle full address <-> offset display - Add 'f' hotkey to the 'perf annotate' TUI interface when in 'disassembler output' mode ('o' hotkey) to toggle showing full virtual address or just the offset. - Cache DSO build-ids when synthesizing PERF_RECORD_MMAP records for pre-existing threads, at the start of a 'perf record' session, speeding up that record startup phase. - Add a command line option to specify build ids in 'perf inject'. - Update JSON event files for the Intel alderlake, broadwell, broadwellde, broadwellx, cascadelakex, haswell, haswellx, icelake, icelakex, ivybridge, ivytown, jaketown, sandybridge, sapphirerapids, skylake, skylakex, and tigerlake processors. - Update vendor JSON event files for the ARM Neoverse V1 and E1 platforms. - Add a 'perf test' entry for 'perf mem' where a struct has false sharing and this gets detected in the 'perf mem' output, tested with Intel, AMD and ARM64 systems. - Add a 'perf test' entry to test the resolution of java symbols, where an output like this is expected: 8.18% jshell jitted-50116-29.so [.] Interpreter 0.75% Thread-1 jitted-83602-1670.so [.] jdk.internal.jimage.BasicImageReader.getString(int) - Add tests for the ARM64 CoreSight hardware tracing feature, with specially crafted pureloop, memcpy, thread loop and unroll tread that then gets traced and the output compared with expected output. Documentation explaining it is also included. - Add per thread Intel PT 'perf test' entry to check that PERF_RECORD_TEXT_POKE events are recorded per CPU, resulting in a mixture of per thread and per CPU events and mmaps, verify that this gets all recorded correctly. - Introduce pthread mutex wrappers to allow for building with clang's -Wthread-safety, i.e. using the "guarded_by" "pt_guarded_by" "lockable", "exclusive_lock_function", "exclusive_trylock_function", "exclusive_locks_required", and "no_thread_safety_analysis" compiler function attributes. - Fix empty version number when building outside of a git repo. - Improve feature detection display when multiple versions of a feature are present, such as for binutils libbfd, that has a mix of possible ways to detect according to the Linux distribution. Previously in some cases we had: Auto-detecting system features <SNIP> ... libbfd: [ on ] ... libbfd-liberty: [ on ] ... libbfd-liberty-z: [ on ] <SNIP> Now for this case we show just the main feature: Auto-detecting system features <SNIP> ... libbfd: [ on ] <SNIP> - Remove some unused structs, variables, macros, function prototypes and includes from various places. * tag 'perf-tools-for-v6.1-1-2022-10-07' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: (169 commits) perf script: Add missing fields in usage hint perf mem: Print "LFB/MAB" for PERF_MEM_LVLNUM_LFB perf mem/c2c: Avoid printing empty lines for unsupported events perf mem/c2c: Add load store event mappings for AMD perf mem/c2c: Set PERF_SAMPLE_WEIGHT for LOAD_STORE events perf mem: Add support for printing PERF_MEM_LVLNUM_{CXL|IO} perf amd ibs: Sync arch/x86/include/asm/amd-ibs.h header with the kernel tools headers UAPI: Sync include/uapi/linux/perf_event.h header with the kernel perf stat: Fix cpu check to use id.cpu.cpu in aggr_printout() perf test coresight: Add relevant documentation about ARM64 CoreSight testing perf test: Add git ignore for tmp and output files of ARM CoreSight tests perf test coresight: Add unroll thread test shell script perf test coresight: Add unroll thread test tool perf test coresight: Add thread loop test shell scripts perf test coresight: Add thread loop test tool perf test coresight: Add memcpy thread test shell script perf test coresight: Add memcpy thread test tool perf test: Add git ignore for perf data generated by the ARM CoreSight tests perf test: Add arm64 asm pureloop test shell script perf test: Add asm pureloop test tool ...
