Merge tag 'perf-tools-for-v5.12-2020-02-19' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tool updates from Arnaldo Carvalho de Melo:
 "New features:

   - Support instruction latency in 'perf report', with both memory
     latency (weight) and instruction latency information, users can
     locate expensive load instructions and understand time spent in
     different stages.

   - Extend 'perf c2c' to display the number of loads which were blocked
     by data or address conflict.

   - Add 'perf stat' support for L2 topdown events in systems such as
     Intel's Sapphire rapids server.

   - Add support for PERF_SAMPLE_CODE_PAGE_SIZE in various tools, as a
     sort key, for instance:

        perf report --stdio --sort=comm,symbol,code_page_size

   - New 'perf daemon' command to run long running sessions while
     providing a way to control the enablement of events without
     restarting a traditional 'perf record' session.

   - Enable counting events for BPF programs in 'perf stat' just like
     for other targets (tid, cgroup, cpu, etc), e.g.:

        # perf stat -e ref-cycles,cycles -b 254 -I 1000
           1.487903822            115,200      ref-cycles
           1.487903822             86,012      cycles
           2.489147029             80,560      ref-cycles
           2.489147029             73,784      cycles
        ^C

     The example above counts 'cycles' and 'ref-cycles' of BPF program
     of id 254. It is similar to bpftool-prog-profile command, but more
     flexible.

   - Support the new layout for PERF_RECORD_MMAP2 to carry the DSO
     build-id using infrastructure generalised from the eBPF subsystem,
     removing the need for traversing the perf.data file to collect
     build-ids at the end of 'perf record' sessions and helping with
     long running sessions where binaries can get replaced in updates,
     leading to possible mis-resolution of symbols.

   - Support filtering by hex address in 'perf script'.

   - Support DSO filter in 'perf script', like in other perf tools.

   - Add namespaces support to 'perf inject'

   - Add support for SDT (Dtrace Style Markers) events on ARM64.

  perf record:

   - Fix handling of eventfd() when draining a buffer in 'perf record'.

   - Improvements to the generation of metadata events for pre-existing
     threads (mmaps, comm, etc), speeding up the work done at the start
     of system wide or per CPU 'perf record' sessions.

  Hardware tracing:

   - Initial support for tracing KVM with Intel PT.

   - Intel PT fixes for IPC

   - Support Intel PT PSB (synchronization packets) events.

   - Automatically group aux-output events to overcome --filter syntax.

   - Enable PERF_SAMPLE_DATA_SRC on ARMs SPE.

   - Update ARM's CoreSight hardware tracing OpenCSD library to v1.0.0.

  perf annotate TUI:

   - Fix handling of 'k' ("show line number") hotkey

   - Fix jump parsing for C++ code.

  perf probe:

   - Add protection to avoid endless loop.

  cgroups:

   - Avoid reading cgroup mountpoint multiple times, caching it.

   - Fix handling of cgroup v1/v2 in mixed hierarchy.

  Symbol resolving:

   - Add OCaml symbol demangling.

   - Further fixes for handling PE executables when using perf with Wine
     and .exe/.dll files.

   - Fix 'perf unwind' DSO handling.

   - Resolve symbols against debug file first, to deal with artifacts
     related to LTO.

   - Fix gap between kernel end and module start on powerpc.

  Reporting tools:

   - The DSO filter shouldn't show samples in unresolved maps.

   - Improve debuginfod support in various tools.

  build ids:

   - Fix 16-byte build ids in 'perf buildid-cache', add a 'perf test'
     entry for that case.

  perf test:

   - Support for PERF_SAMPLE_WEIGHT_STRUCT.

   - Add test case for PERF_SAMPLE_CODE_PAGE_SIZE.

   - Shell based tests for 'perf daemon's commands ('start', 'stop,
     'reconfig', 'list', etc).

   - ARM cs-etm 'perf test' fixes.

   - Add parse-metric memory bandwidth testcase.

  Compiler related:

   - Fix 'perf probe' kretprobe issue caused by gcc 11 bug when used
     with -fpatchable-function-entry.

   - Fix ARM64 build with gcc 11's -Wformat-overflow.

   - Fix unaligned access in sample parsing test.

   - Fix printf conversion specifier for IP addresses on arm64, s390 and
     powerpc.

  Arch specific:

   - Support exposing Performance Monitor Counter SPRs as part of
     extended regs on powerpc.

   - Add JSON 'perf stat' metrics for ARM64's imx8mp, imx8mq and imx8mn
     DDR, fix imx8mm ones.

   - Fix common and uarch events for ARM64's A76 and Ampere eMag"

NAME
----
perf-daemon - Run record sessions on background
SYNOPSIS
--------
[verse]
'perf daemon'
'perf daemon' [<options>]
'perf daemon start' [<options>]
'perf daemon stop' [<options>]
'perf daemon signal' [<options>]
'perf daemon ping' [<options>]
DESCRIPTION
-----------
This command allows to run simple daemon process that starts and
monitors configured record sessions.
You can imagine 'perf daemon' of background process with several
'perf record' child tasks, like:
# ps axjf
...
1 916507 ... perf daemon start
916507 916508 ... \_ perf record --control=fifo:control,ack -m 10M -e cycles --overwrite --switch-output -a
916507 916509 ... \_ perf record --control=fifo:control,ack -m 20M -e sched:* --overwrite --switch-output -a
Not every 'perf record' session is suitable for running under daemon.
User need perf session that either produces data on query, like the
flight recorder sessions in above example or session that is configured
to produce data periodically, like with --switch-output configuration
for time and size.
Each session is started with control setup (with perf record --control
options).
Sessions are configured through config file, see CONFIG FILE section
with EXAMPLES.
OPTIONS
-------
-v::
--verbose::
Be more verbose.
--config=<PATH>::
Config file path. If not provided, perf will check system and default
locations (/etc/perfconfig, $HOME/.perfconfig).
--base=<PATH>::
Base directory path. Each daemon instance is running on top
of base directory. Only one instance of server can run on
top of one directory at the time.
All generic options are available also under commands.
START COMMAND
-------------
The start command creates the daemon process.
-f::
--foreground::
Do not put the process in background.
STOP COMMAND
------------
The stop command stops all the session and the daemon process.
SIGNAL COMMAND
--------------
The signal command sends signal to configured sessions.
--session::
Send signal to specific session.
PING COMMAND
------------
The ping command sends control ping to configured sessions.
--session::
Send ping to specific session.
CONFIG FILE
-----------
The daemon is configured within standard perf config file by
following new variables:
daemon.base:
Base path for daemon data. All sessions data are
stored under this path.
session-<NAME>.run:
Defines new record session. The value is record's command
line without the 'record' keyword.
Each perf record session is run in daemon.base/<NAME> directory.
EXAMPLES
--------
Example with 2 record sessions:
# cat ~/.perfconfig
[daemon]
base=/opt/perfdata
[session-cycles]
run = -m 10M -e cycles --overwrite --switch-output -a
[session-sched]
run = -m 20M -e sched:* --overwrite --switch-output -a
Starting the daemon:
# perf daemon start
Check sessions:
# perf daemon
[603349:daemon] base: /opt/perfdata
[603350:cycles] perf record -m 10M -e cycles --overwrite --switch-output -a
[603351:sched] perf record -m 20M -e sched:* --overwrite --switch-output -a
First line is daemon process info with configured daemon base.
Check sessions with more info:
# perf daemon -v
[603349:daemon] base: /opt/perfdata
output: /opt/perfdata/output
lock: /opt/perfdata/lock
up: 1 minutes
[603350:cycles] perf record -m 10M -e cycles --overwrite --switch-output -a
base: /opt/perfdata/session-cycles
output: /opt/perfdata/session-cycles/output
control: /opt/perfdata/session-cycles/control
ack: /opt/perfdata/session-cycles/ack
up: 1 minutes
[603351:sched] perf record -m 20M -e sched:* --overwrite --switch-output -a
base: /opt/perfdata/session-sched
output: /opt/perfdata/session-sched/output
control: /opt/perfdata/session-sched/control
ack: /opt/perfdata/session-sched/ack
up: 1 minutes
The 'base' path is daemon/session base.
The 'lock' file is daemon's lock file guarding that no other
daemon is running on top of the base.
The 'output' file is perf record output for specific session.
The 'control' and 'ack' files are perf control files.
The 'up' number shows minutes daemon/session is running.
Make sure control session is online:
# perf daemon ping
OK cycles
OK sched
Send USR2 signal to session 'cycles' to generate perf.data file:
# perf daemon signal --session cycles
signal 12 sent to session 'cycles [603452]'
# tail -2 /opt/perfdata/session-cycles/output
[ perf record: dump data: Woken up 1 times ]
[ perf record: Dump perf.data.2020123017013149 ]
Send USR2 signal to all sessions:
# perf daemon signal
signal 12 sent to session 'cycles [603452]'
signal 12 sent to session 'sched [603453]'
# tail -2 /opt/perfdata/session-cycles/output
[ perf record: dump data: Woken up 1 times ]
[ perf record: Dump perf.data.2020123017024689 ]
# tail -2 /opt/perfdata/session-sched/output
[ perf record: dump data: Woken up 1 times ]
[ perf record: Dump perf.data.2020123017024713 ]
Stop daemon:
# perf daemon stop

Tracing Virtual Machines
------------------------
Currently, only kernel tracing is supported and only with "timeless" decoding
i.e. no TSC timestamps
Other limitations and caveats
VMX controls may suppress packets needed for decoding resulting in decoding errors
VMX controls may block the perf NMI to the host potentially resulting in lost trace data
Guest kernel self-modifying code (e.g. jump labels or JIT-compiled eBPF) will result in decoding errors
Guest thread information is unknown
Guest VCPU is unknown but may be able to be inferred from the host thread
Callchains are not supported
Example
Start VM
$ sudo virsh start kubuntu20.04
Domain kubuntu20.04 started
Mount the guest file system. Note sshfs needs -o direct_io to enable reading of proc files. root access is needed to read /proc/kcore.
$ mkdir vm0
$ sshfs -o direct_io root@vm0:/ vm0
Copy the guest /proc/kallsyms, /proc/modules and /proc/kcore
$ perf buildid-cache -v --kcore vm0/proc/kcore
kcore added to build-id cache directory /home/user/.debug/[kernel.kcore]/9600f316a53a0f54278885e8d9710538ec5f6a08/2021021807494306

Start an open-ended perf record, tracing the VM process, do something on the VM, and then ctrl-C to stop.
TSC is not supported and tsc=0 must be specified. That means mtc is useless, so add mtc=0.
However, IPC can still be determined, hence cyc=1 can be added.
Only kernel decoding is supported, so 'k' must be specified.
Intel PT traces both the host and the guest so --guest and --host need to be specified.
Without timestamps, --per-thread must be specified to distinguish threads.
$ sudo perf kvm --guest --host --guestkallsyms $KALLSYMS record --kcore -e intel_pt/tsc=0,mtc=0,cyc=1/k -p 1430 --per-thread

Extension on Sapphire Rapids Server
===================================
The metrics counter is extended to support TMA method level 2 metrics.
The lower half of the register is the TMA level 1 metrics (legacy).
The upper half is also divided into four 8-bit fields for the new level 2
metrics. Four more TopDown metric events are exposed for the end-users,
topdown-heavy-ops, topdown-br-mispredict, topdown-fetch-lat and
topdown-mem-bound.
Each of the new level 2 metrics in the upper half is a subset of the
corresponding level 1 metric in the lower half. Software can deduce the
other four level 2 metrics by subtracting corresponding metrics as below.
