Tracing updates for 5.14:
- Added option for per CPU threads to the hwlat tracer - Have hwlat tracer handle hotplug CPUs - New tracer: osnoise, that detects latency caused by interrupts, softirqs and scheduling of other tasks. - Added timerlat tracer that creates a thread and measures in detail what sources of latency it has for wake ups. - Removed the "success" field of the sched_wakeup trace event. This has been hardcoded as "1" since 2015, no tooling should be looking at it now. If one exists, we can revert this commit, fix that tool and try to remove it again in the future. - tgid mapping fixed to handle more than PID_MAX_DEFAULT pids/tgids. - New boot command line option "tp_printk_stop", as tp_printk causes trace events to write to console. When user space starts, this can easily live lock the system. Having a boot option to stop just after boot up is useful to prevent that from happening. - Have ftrace_dump_on_oops boot command line option take numbers that match the numbers shown in /proc/sys/kernel/ftrace_dump_on_oops. - Bootconfig clean ups, fixes and enhancements. - New ktest script that tests bootconfig options. - Add tracepoint_probe_register_may_exist() to register a tracepoint without triggering a WARN*() if it already exists. BPF has a path from user space that can do this. All other paths are considered a bug. - Small clean ups and fixes -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCYN8YPhQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qhxLAP9Mo5hHv7Hg6W7Ddv77rThm+qclsMR/ yW0P+eJpMm4+xAD8Cq03oE1DimPK+9WZBKU5rSqAkqG6CjgDRw6NlIszzQQ= =WEPR -----END PGP SIGNATURE----- Merge tag 'trace-v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: - Added option for per CPU threads to the hwlat tracer - Have hwlat tracer handle hotplug CPUs - New tracer: osnoise, that detects latency caused by interrupts, softirqs and scheduling of other tasks. - Added timerlat tracer that creates a thread and measures in detail what sources of latency it has for wake ups. - Removed the "success" field of the sched_wakeup trace event.

sound updates for 5.14
As the diffstat scatters over the tree, we've got many tree-wide small changes, but also got quite a few intrusive changes in the core side. The only ABI-visible core change is the new rawmidi framing mode support while others are kernel-internal, mostly code refactoring and/or nice improvements. Here are some highlights: Core: - A new framing access mode for rawmidi to get timestamps - Cleanup / refactoring of buffer memory management helper code - Support for automatic negotiation of ASoC DAI formats - Revival of software suspend for PCM and control core, as a preliminary work for PCI BAR rescan support ASoC: - Accessory detection support for several Qualcomm parts - Support for IEC958 control with hdmi-codec - Merging of Tegra machine drivers into a single driver - Support for AmLogic SM1 TOACODEC, Intel AlderLake-M, several NXP i.MX8 variants, NXP TFA1 and TDF9897, Rockchip RK817, Qualcomm Quinary MI2S, Texas Instruments TAS2505 USB-audio: - Reduction of latency at playback start - Code cleanup / fixes of usx2y driver - Scarlett2 mixer code fixes and enhancements - Quirks for Ozone and Denon devices HD-audio: - A few quirks for HP and ASUS machines - Display power management fixes Others: - FireWire code refactoring and enhancements - Tree-wide trivial coding-style fixes -----BEGIN PGP SIGNATURE----- iQJCBAABCAAsFiEEIXTw5fNLNI7mMiVaLtJE4w1nLE8FAmDezZ8OHHRpd2FpQHN1 c2UuZGUACgkQLtJE4w1nLE8kxhAAhWyQBU9HX7xo/132J0SsP0tqT0NhePr217T7 RSmRre3kD8iNDtpe9P9eziyN5q5TB8+InY52yUiDiWdSxCHOBDKBPwzzDeVRdOGg /BdQqCtEAtdgzsnPEsXxvK+y3LayLwlkCyN1kMLCl4KGFfMg8fQgMbXobEOfyKwT r23Xgbkb8jIFyjEAmvJnbvPXjkUjv2ew0+RB+cqV80m9h+KdNN/k/8+0wdWaQBEd 6oRSE8ApYclgyLf4TYCkLAwTP3NQ8SuvYSuZ9tFGy7vjz7l69xPWS/6ndbfrJvEP pO615dYWKTWQKi2SjStnjFUH7ODirbPZzyDqU9tvEAGbKj0l07LNXy0JrbwJ8VB2 JBfsdTlmSwHcAXmj0JB7IhflmG96W9azUKf1a8YNJLw7UgHoXjDZC0NFtOanaB7x PEdf+27Ty1pZaNbtJpwdzEyc06UNA8dNRAr6FsSMphRTnBBzcUz2uEAfWbevS7Yl Q5IOZd2lqKIUHPB6j2r0iDiCKScXzlHVhFzOLj3vHS4L8vjfbVshxkIkSY0HeA9r HINbkby2mpk901oyqaFwTLkoatXBk5zDX2m2ow7rQLLUIdF0hWBXrE5Xrl3c/T/x aFXuDxJfZm4YibJiBAOO5xv03DzVBNJz01E020oyum2m0NHhB1xD3RK428pcjshV zgXJaZg= =IN9G -----END PGP SIGNATURE----- Merge tag 'sound-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "As the diffstat scatters over the tree, we've got many tree-wide small changes, but also got quite a few intrusive changes in the core side.

The biggest non-cleanup changes are (1) reducing the number of cache flushes sent when writing the log; (2) a substantial number of log recovery fixes; and (3) I started accepting pull requests from contributors if the commits in their branches match what's been sent to the list. For a week or so I /had/ staged a major cleanup of the logging code from Dave Chinner, but it exposed so many lurking bugs in other parts of the logging and log recovery code that I decided to defer that patchset until we can address those latent bugs. Larger cleanups this time include walking the incore inode cache (me) and rework of the extended attribute code (Allison) to prepare it for adding logged xattr updates (and directory tree parent pointers) in future releases. Summary: - Refactor the buffer cache to use bulk page allocation - Convert agnumber-based AG iteration to walk per-AG structures - Clean up some unit conversions and other code warts - Reduce spinlock contention in the directio fastpath - Collapse all the inode cache walks into a single function - Remove indirect function calls from the inode cache walk code - Dramatically reduce the number of cache flushes sent when writing log buffers - Preserve inode sickness reports for longer - Rename xfs_eofblocks since it controls inode cache walks - Refactor the extended attribute code to prepare it for the addition of log intent items to make xattrs fully transactional - A few fixes to earlier large patchsets - Log recovery fixes so that we don't accidentally mark the log clean when log intent recovery fails - Fix some latent SOB errors - Clean up shutdown messages that get logged to dmesg - Fix a regression in the online shrink code - Fix a UAF in the buffer logging code if the fs goes offline - Fix uninitialized error variables - Fix a UAF in the CIL when commited log item callbacks race with a shutdown - Fix a bug where the CIL could hang trying to push part of the log ring buffer that hasn't been filled yet" * tag 'xfs-5.14-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (102 commits) xfs: don't wait on future iclogs when pushing the CIL xfs: Fix a CIL UAF by getting get rid of the iclog callback lock xfs: remove callback dequeue loop from xlog_state_do_iclog_callbacks xfs: don't nest icloglock inside ic_callback_lock xfs: Initialize error in xfs_attr_remove_iter xfs: fix endianness issue in xfs_ag_shrink_space xfs: remove dead stale buf unpin handling code xfs: hold buffer across unpin and potential shutdown processing xfs: force the log offline when log intent item recovery fails xfs: fix log intent recovery ENOSPC shutdowns when inactivating inodes xfs: shorten the shutdown messages to a single line xfs: print name of function causing fs shutdown instead of hex pointer xfs: fix type mismatches in the inode reclaim functions xfs: separate primary inode selection criteria in xfs_iget_cache_hit xfs: refactor the inode recycling code xfs: add iclog state trace events xfs: xfs_log_force_lsn isn't passed a LSN xfs: Fix CIL throttle hang when CIL space used going backwards xfs: journal IO cache flush reductions xfs: remove need_start_rec parameter from xlog_write() ... |

asm-generic/unaligned: Unify asm/unaligned.h around struct helper
The get_unaligned()/put_unaligned() helpers are traditionally architecture specific, with the two main variants being the "access-ok.h" version that assumes unaligned pointer accesses always work on a particular architecture, and the "le-struct.h" version that casts the data to a byte aligned type before dereferencing, for architectures that cannot always do unaligned accesses in hardware.

This is the bulk of pin control changes for the v5.14 kernel:
New drivers: - Last merge window we created a driver for the Ralink RT2880. We are now moving the Ralink SoC pin control drivers out of the MIPS architecture code and into the pin control subsystem. This concerns RT288X, MT7620, RT305X, RT3883 and MT7621. - Qualcomm SM6125 SoC pin control driver. - Qualcomm spmi-gpio support for PM7325. - Qualcomm spmi-mpp also handles PMI8994 (just a compatible string) - Mediatek MT8365 SoC pin controller. - New device HID for the AMD GPIO controller. Improvements: - Pin bias config support for a slew of Renesas pin controllers. - Incremental improvements and non-urgent bug fixes to the Renesas SoC drivers. - Implement irq_set_wake on the AMD pin controller so we can wake up from external pin events.

This round has a diffstat dominated by Qualcomm clk drivers. Honestly though
that's just a bunch of data so the diffstat reflects that. Looking beyond that there's just a bunch of updates all around in various clk drivers. Renesas and NXP (for i.MX) are two SoC vendors that have a lot of patches in here. Overall the driver changes look to be mostly enabling more clks and non-critical fixes that we could hold until the next merge window.

perf session: Add missing evlist__delete when deleting a session
ASan reports a memory leak caused by evlist not being deleted on exit in perf-report, perf-script and perf-data. The problem is caused by evlist->session not being deleted, which is allocated in perf_session__read_header, called in perf_session__new if perf_data is in read mode. In case of write mode, the session->evlist is filled by the caller. This patch solves the problem by calling evlist__delete in perf_session__delete if perf_data is in read mode. Changes in v2: - call evlist__delete from within perf_session__delete v1: https://lore.kernel.org/lkml/20210621234317.235545-1-rickyman7@gmail.com/ ASan report follows: $ ./perf script report

perf annotate: Allow 's' on source code lines
In perf annotate, when 's' is pressed on a line containing source code, it shows the message "Only available for assembly lines". This patch gets rid of the error, moving the cursr to the next available asm line (or the closest previous one if no asm line is found moving forwards), before hiding source code lines. Changes in v2: - handle case of no asm line found in annotate_browser__find_next_asm_line by returning NULL and handling error in caller.

perf script: Add API for filtering via dynamically loaded shared object
In some cases, users want to filter very large amounts of data (e.g. from AUX area tracing like Intel PT) looking for something specific. While scripting such as Python can be used, Python is 10 to 20 times slower than C. So define a C API so that custom filters can be written and loaded.

perf cs-etm: Delay decode of non-timeless data until cs_etm__flush_events()
Currently, timeless mode starts the decode on PERF_RECORD_EXIT, and non-timeless mode starts decoding on the fist PERF_RECORD_AUX record. This can cause the "data has no samples!" error if the first PERF_RECORD_AUX record comes before the first (or any relevant) PERF_RECORD_MMAP2 record because the mmaps are required by the decoder to access the binary data. This change pushes the start of non-timeless decoding to the very end of parsing the file. The PERF_RECORD_EXIT event can't be used because it might not exist in system-wide or snapshot modes. I have not been able to find the exact cause for the events to be intermittently in the wrong order in the basic scenario: perf record -e cs_etm/@tmc_etr0/u top But it can be made to happen every time with the --delay option. This is because "enable_on_exec" is disabled, which causes tracing to start before the process to be launched is exec'd. For example: perf record -e cs_etm/@tmc_etr0/u --delay=1 top perf report -D | grep 'AUX\|MAP' 0 16714475632740 0x520 [0x40]: PERF_RECORD_AUX offset: 0 size: 0x30 flags: 0 [] 0 16714476494960 0x5d0 [0x40]: PERF_RECORD_AUX offset: 0x30 size: 0x30 flags: 0 [] 0 16714478208900 0x660 [0x40]: PERF_RECORD_AUX offset: 0x60 size: 0x30 flags: 0 [] 4294967295 16714478293340 0x700 [0x70]: PERF_RECORD_MMAP2 8712/8712: [0x557a460000(0x54000) @ 0 00:17 5329258 0]: r-xp /usr/bin/top 4294967295 16714478353020 0x770 [0x88]: PERF_RECORD_MMAP2 8712/8712: [0x7f86f72000(0x34000) @ 0 00:17 5214354 0]: r-xp /usr/lib/aarch64-linux-gnu/ld-2.31.so Another scenario in which decoding from the first aux record fails is a workload that forks. Although the aux record comes after 'bash', it comes before 'top', which is what we are interested in. For example: perf record -e cs_etm/@tmc_etr0/u -- bash -c top perf report -D | grep 'AUX\|MAP' 4294967295 16853946421300 0x510 [0x70]: PERF_RECORD_MMAP2 8723/8723: [0x558f280000(0x142000) @ 0 00:17 5213953 0]: r-xp /usr/bin/bash 4294967295 16853946543560 0x580 [0x88]: PERF_RECORD_MMAP2 8723/8723: [0x7fbba6e000(0x34000) @ 0 00:17 5214354 0]: r-xp /usr/lib/aarch64-linux-gnu/ld-2.31.so 4294967295 16853946628420 0x608 [0x68]: PERF_RECORD_MMAP2 8723/8723: [0x7fbba9e000(0x1000) @ 0 00:00 0 0]: r-xp [vdso] 0 16853947067300 0x690 [0x40]: PERF_RECORD_AUX offset: 0 size: 0x3a60 flags: 0 [] ... 0 16853966602580 0x1758 [0x40]: PERF_RECORD_AUX offset: 0xc2470 size: 0x30 flags: 0 [] 4294967295 16853967119860 0x1818 [0x70]: PERF_RECORD_MMAP2 8723/8723: [0x5559e70000(0x54000) @ 0 00:17 5329258 0]: r-xp /usr/bin/top 4294967295 16853967181620 0x1888 [0x88]: PERF_RECORD_MMAP2 8723/8723: [0x7f9ed06000(0x34000) @ 0 00:17 5214354 0]: r-xp /usr/lib/aarch64-linux-gnu/ld-2.31.so 4294967295 16853967237180 0x1910 [0x68]: PERF_RECORD_MMAP2 8723/8723: [0x7f9ed36000(0x1000) @ 0 00:00 0 0]: r-xp [vdso] A third scenario is when the majority of time is spent in a shared library that is not loaded at startup. For example a dynamically loaded plugin. Testing ======= Testing was done by checking if any samples that are present in the old output are missing from the new output. Timestamps must be stripped out with awk because now they are set to the last AUX sample, rather than the first: ./perf script $4 | awk '!($4="")' > new.script ./perf-default script $4 | awk '!($4="")' > default.script comm -13 <(sort -u new.script) <(sort -u default.script) Testing showed that the new output is a superset of the old. When lines appear in the comm output, it is not because they are missing but because [unknown] is now resolved to sensible locations. For example last putp branch here now resolves to libtinfo, so it's not missing from the output, but is actually improved: Old: top 305 [001] 1 branches:uH: 402830 _init+0x30 (/usr/bin/top.procps) => 404a1c [unknown] (/usr/bin/top.procps) top 305 [001] 1 branches:uH: 404a20 [unknown] (/usr/bin/top.procps) => 402970 putp@plt+0x0 (/usr/bin/top.procps) top 305 [001] 1 branches:uH: 40297c putp@plt+0xc (/usr/bin/top.procps) => 0 [unknown] ([unknown]) New: top 305 [001] 1 branches:uH: 402830 _init+0x30 (/usr/bin/top.procps) => 404a1c [unknown] (/usr/bin/top.procps) top 305 [001] 1 branches:uH: 404a20 [unknown] (/usr/bin/top.procps) => 402970 putp@plt+0x0 (/usr/bin/top.procps) top 305 [001] 1 branches:uH: 40297c putp@plt+0xc (/usr/bin/top.procps) => 7f8ab39208 putp+0x0 (/lib/libtinfo.so.5.9) In the following two modes, decoding now works and the "data has no samples!" error is not displayed any more: perf record -e cs_etm/@tmc_etr0/u -- bash -c top perf record -e cs_etm/@tmc_etr0/u --delay=1 top In snapshot mode, there is also an improvement to decoding. Previously samples for the 'kill' process that was used to send SIGUSR2 were completely missing, because the process hadn't started yet. But now there are additional samples present: perf record -e cs_etm/@tmc_etr0/u --snapshot -a perf script stress 19380 [003] 161627.938153: 1000000 instructions:uH: aaaabb612fb4 [unknown] (/usr/bin/stress) kill 19644 [000] 161627.938153: 1000000 instructions:uH: ffffae0ef210 [unknown] (/lib/aarch64-linux-gnu/ld-2.27.so) stress 19380 [003] 161627.938153: 1000000 instructions:uH: ffff9e754d40 random_r+0x20 (/lib/aarch64-linux-gnu/libc-2.27.so) Also tested was the round trip of 'perf inject' followed by 'perf report' which has the same differences and improvements.

perf arm-spe: Don't wait for PERF_RECORD_EXIT event
When decode Arm SPE trace, it waits for PERF_RECORD_EXIT event (the last perf event) for processing trace data, which is needless and even might cause logic error, e.g. it might fail to correlate perf events with Arm SPE events correctly. So this patch removes the condition checking for PERF_RECORD_EXIT event.

perf arm-spe: Bail out if the trace is later than perf event
It's possible that record in Arm SPE trace is later than perf event and vice versa. This asks to correlate the perf events and Arm SPE synthesized events to be processed in the manner of correct timing. To achieve the time ordering, this patch reverses the flow, it firstly calls arm_spe_sample() and then calls arm_spe_decode(). By comparing the timestamp value and detect the perf event is coming earlier than Arm SPE trace data, it bails out from the decoding loop, the last record is pushed into auxtrace stack and is deferred to generate sample. To track the timestamp, everytime it updates timestamp for the latest record.

perf arm-spe: Assign kernel time to synthesized event
In current code, it assigns the arch timer counter to the synthesized samples Arm SPE trace, thus the samples don't contain the kernel time but only contain the raw counter value. To fix the issue, this patch converts the timer counter to kernel time and assigns it to sample timestamp.

perf arm-spe: Convert event kernel time to counter value
When handle a perf event, Arm SPE decoder needs to decide if this perf event is earlier or later than the samples from Arm SPE trace data; to do comparision, it needs to use the same unit for the time. This patch converts the event kernel time to arch timer's counter value, thus it can be used to compare with counter value contained in Arm SPE Timestamp packet.
