Add a new CLOCK_DATA feature that stores reference times when -k/--clockid option is specified. It contains the clock id and its reference time together with wall clock time taken at the 'same time', both values are in nanoseconds. The format of data is as below: struct { u32 version; /* version = 1 */ u32 clockid; u64 wall_clock_ns; u64 clockid_time_ns; }; This clock reference times will be used in following changes to display wall clock for perf events. It's available only for recording with clockid specified, because it's the only case where we can get reference time to wallclock time. It's can't do that with perf clock yet. Committer testing: $ perf record -h -k Usage: perf record [<options>] [<command>] or: perf record [<options>] -- <command> [<options>] -k, --clockid <clockid> clockid to use for events, see clock_gettime() $ perf record -k monotonic sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.017 MB perf.data (8 samples) ] $ perf report --header-only | grep clockid -A1 # event : name = cycles:u, , id = { 88815, 88816, 88817, 88818, 88819, 88820, 88821, 88822 }, size = 120, { sample_period, sample_freq } = 4000, sample_type = IP|TID|TIME|PERIOD, read_format = ID, disabled = 1, inherit = 1, exclude_kernel = 1, mmap = 1, comm = 1, freq = 1, enable_on_exec = 1, task = 1, precise_ip = 3, sample_id_all = 1, exclude_guest = 1, mmap2 = 1, comm_exec = 1, use_clockid = 1, ksymbol = 1, bpf_event = 1, clockid = 1 # CPU_TOPOLOGY info available, use -I to display -- # clockid frequency: 1000 MHz # cpu pmu capabilities: branches=32, max_precise=3, pmu_name=skylake # clockid: monotonic (1) # reference time: 2020-08-06 09:40:21.619290 = 1596717621.619290 (TOD) = 21931.077673635 (monotonic) $ Original-patch-by:David Ahern <dsahern@gmail.com> Signed-off-by:

Move parse_clockid and all needed clcckid related stuff into clockid object. We are going to add clockid_name function in following change, so it's better it's placed in separated object and not in builtin-record.c. No functional change is intended. Signed-off-by:

A single q option decodes ip from only FUP/TIP packets. Make it so that repeating the q option (i.e. qq) decodes only PSB+, getting ip if there is a FUP packet within PSB+ (i.e. between PSB and PSBEND). Example: $ perf record -e intel_pt//u grep -rI pudding drivers [ perf record: Woken up 52 times to write data ] [ perf record: Captured and wrote 57.870 MB perf.data ] $ time perf script --itrace=bi | wc -l 58948289 real 1m23.863s user 1m23.251s sys 0m7.452s $ time perf script --itrace=biq | wc -l 3385694 real 0m4.453s user 0m4.455s sys 0m0.328s $ time perf script --itrace=biqq | wc -l 1883 real 0m0.047s user 0m0.043s sys 0m0.009s Signed-off-by:

Use the new itrace 'q' option to add support for a mode of decoding that ignores TNT, does not walk object code, but gets the ip from FUP and TIP packets.

The 'q' option is for modes of decoding that are quicker because they skip or omit decoding some aspects of trace data. If supported, the 'q' option may be repeated to increase the effect. Signed-off-by:

Change the debug logging (when used with the --time option) to time filter logged perf events, but allow that to be overridden by using "d+a" instead of plain "d". That can reduce the size of the log file. Signed-off-by:

Adrian Hunter authored
The "d" option may be followed by flags which affect what debug messages will or will not be logged. Each flag must be preceded by either '+' or '-'.

The itrace "e" option may be followed by flags which affect what errors will or will not be reported. Each flag must be preceded by either '+' or '-'. The flags supported by Intel PT are: -o Suppress overflow errors -l Suppress trace data lost errors For example, for errors but not overflow or data lost errors: --itrace=e-o-l Suppressing those errors can be useful for testing and debugging because they are not due to decoding.

While walking code towards a FUP ip, the packet state is INTEL_PT_STATE_FUP or INTEL_PT_STATE_FUP_NO_TIP. That was mishandled resulting in the state becoming INTEL_PT_STATE_IN_SYNC prematurely. The result was an occasional lost EXSTOP event. Signed-off-by:

Oliver Neukum says: ==================== misc bug fixes for the hso driver 1. Code reuse led to an unregistration of a net driver that has not been registered 2. The kernel complains generically if kmalloc with GFP_KERNEL fails 3. A race that can lead to an URB that is in use being reused or a use after free ==================== Signed-off-by: -

This check an inherent race. It opens a race where an error code has already been set or cleared yet the URB has not been given back. We cannot do such an optimization and must unlink unconditionally. Signed-off-by:

If this fails, kmalloc() will print a report including a stack trace. There is no need for a separate complaint. Signed-off-by:

The driver tries to reuse code for disconnect in case of a failed probe. If resources need to be freed after an error in probe, the netdev must not be freed because it has never been registered. Fix it by telling the helper which path we are in. Signed-off-by:

Pull hmm updates from Jason Gunthorpe: "Ralph has been working on nouveau's use of hmm_range_fault() and migrate_vma() which resulted in this small series. It adds reporting of the page table order from hmm_range_fault() and some optimization of migrate_vma(): - Report the size of the page table mapping out of hmm_range_fault(). This makes it easier to establish a large/huge/etc mapping in the device's page table. - Allow devices to ignore the invalidations during migration in cases where the migration is not going to change pages. For instance migrating pages to a device does not require the device to invalidate pages already in the device. - Update nouveau and hmm_tests to use the above" * tag 'for-linus-hmm' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: mm/hmm/test: use the new migration invalidation nouveau/svm: use the new migration invalidation mm/notifier: add migration invalidation type mm/migrate: add a flags parameter to migrate_vma nouveau: fix storing invalid ptes nouveau/hmm: support mapping large sysmem pages nouveau: fix mapping 2MB sysmem pages nouveau/hmm: fault one page at a time mm/hmm: add tests for hmm_pfn_to_map_order() mm/hmm: provide the page mapping order in hmm_range_fault() -

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v5.9 kernel cycle. There is nothing too exciting in it, but a new macro that fixes a build failure on a minor ARM32 platform that appeared yesterday is part of it so we better merge it. Core changes: - Introduce the for_each_requested_gpio() macro to help in dependent code all over the place. Also patch a few locations to use it while we are at it. - Split out the sysfs code into its own file. - Split out the character device code into its own file, then make a set of refactorings and improvements to this code. We are setting the stage to revamp the userspace API a bit in the next cycle. - Fix a whole slew of kerneldoc that was wrong or missing. New drivers: - The PCA953x driver now supports the PCAL9535. Driver improvements: - A host of incremental modernizations and improvements to the PCA953x driver. - Incremental improvements to the Xilinx Zynq driver. - Some improvements to the GPIO aggregator driver. - I ran all over the place switching all threaded and other drivers requesting their own IRQ while using the core GPIO IRQ helpers to pass the GPIO irq chip as a template instead of calling the explicit set-up functions.
