perf tools changes for v6.0: 1st batch 

- Introduce 'perf lock contention' subtool, using new lock contention
   tracepoints and using BPF for in kernel aggregation and then userspace
   processing using the perf tooling infrastructure for resolving symbols, target
   specification, etc.
 
   Since the new lock contention tracepoints don't provide lock names, get up to
   8 stack traces and display the first non-lock function symbol name as a caller:
 
   $ perf lock report -F acquired,contended,avg_wait,wait_total
 
                   Name   acquired  contended     avg wait    total wait
 
    update_blocked_a...         40         40      3.61 us     144.45 us
    kernfs_fop_open+...          5          5      3.64 us      18.18 us
     _nohz_idle_balance          3          3      2.65 us       7.95 us
    tick_do_update_j...          1          1      6.04 us       6.04 us
     ep_scan_ready_list          1          1      3.93 us       3.93 us
 
   Supports the usual 'perf record' + 'perf report' workflow as well as a
   BCC/bpftrace like mode where you start the tool and then press control+C to get
   results:
 
    $ sudo perf lock contention -b
   ^C
    contended   total wait     max wait     avg wait         type   caller
 
           42    192.67 us     13.64 us      4.59 us     spinlock   queue_work_on+0x20

   ...
 
 - Add new 'perf kwork' tool to trace time properties of kernel work (such as
   softirq, and workqueue), uses eBPF skeletons to collect info in kernel space,
   aggregating data that then gets processed by the userspace tool, e.g.:

  - Data returned from DRAM.
  - A peer cache in a far CCX.
  - DRAM address map with "long latency" bit set.

Insert events from a perf.data file recorded in a virtual machine at
the same time as the input perf.data file was recorded on the host.
The Process ID (PID) of the QEMU hypervisor process must be provided,
and the time offset and time scale (multiplier) will likely be needed
to convert guest time stamps into host time stamps. For example, for
x86 the TSC Offset and Multiplier could be provided for a virtual machine
using Linux command line option no-kvmclock.
Currently only mmap, mmap2, comm, task, context_switch, ksymbol,
and text_poke events are inserted, as well as build ID information.
The QEMU option -name debug-threads=on is needed so that thread names
can be used to determine which thread is running which VCPU. Note
libvirt seems to use this by default.
When using perf record in the guest, option --sample-identifier
should be used, and also --buildid-all and --switch-events may be
useful.

Tracing Virtual Machines (including user space)
-----------------------------------------------
It is possible to use perf record to record sideband events within a virtual machine, so that an Intel PT trace on the host can be decoded.
Sideband events from the guest perf.data file can be injected into the host perf.data file using perf inject.
Here is an example of the steps needed:
On the guest machine:
Check that no-kvmclock kernel command line option was used to boot:
Note, this is essential to enable time correlation between host and guest machines.
$ cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-5.10.0-16-amd64 root=UUID=cb49c910-e573-47e0-bce7-79e293df8e1d ro no-kvmclock
There is no BPF support at present so, if possible, disable JIT compiling:
$ echo 0 | sudo tee /proc/sys/net/core/bpf_jit_enable
0
Start perf record to collect sideband events:
$ sudo perf record -o guest-sideband-testing-guest-perf.data --sample-identifier --buildid-all --switch-events --kcore -a -e dummy
On the host machine:
Start perf record to collect Intel PT trace:
Note, the host trace will get very big, very fast, so the steps from starting to stopping the host trace really need to be done so that they happen in the shortest time possible.
$ sudo perf record -o guest-sideband-testing-host-perf.data -m,64M --kcore -a -e intel_pt/cyc/
On the guest machine:
Run a small test case, just 'uname' in this example:
$ uname
Linux
On the host machine:
Stop the Intel PT trace:
^C
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 76.122 MB guest-sideband-testing-host-perf.data ]
On the guest machine:
Stop the Intel PT trace:
^C
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 1.247 MB guest-sideband-testing-guest-perf.data ]
And then copy guest-sideband-testing-guest-perf.data to the host (not shown here).
On the host machine:
With the 2 perf.data recordings, and with their ownership changed to the user.
Identify the TSC Offset:
$ perf inject -i guest-sideband-testing-host-perf.data --vm-time-correlation=dry-run
VMCS: 0x103fc6 TSC Offset 0xfffffa6ae070cb20
VMCS: 0x103ff2 TSC Offset 0xfffffa6ae070cb20
VMCS: 0x10fdaa TSC Offset 0xfffffa6ae070cb20
VMCS: 0x24d57c TSC Offset 0xfffffa6ae070cb20
Correct Intel PT TSC timestamps for the guest machine:
$ perf inject -i guest-sideband-testing-host-perf.data --vm-time-correlation=0xfffffa6ae070cb20 --force
Identify the guest machine PID:
$ perf script -i guest-sideband-testing-host-perf.data --no-itrace --show-task-events | grep KVM
CPU 0/KVM 0 [000] 0.000000: PERF_RECORD_COMM: CPU 0/KVM:13376/13381
CPU 1/KVM 0 [000] 0.000000: PERF_RECORD_COMM: CPU 1/KVM:13376/13382
CPU 2/KVM 0 [000] 0.000000: PERF_RECORD_COMM: CPU 2/KVM:13376/13383
CPU 3/KVM 0 [000] 0.000000: PERF_RECORD_COMM: CPU 3/KVM:13376/13384
Note, the QEMU option -name debug-threads=on is needed so that thread names
can be used to determine which thread is running which VCPU as above. libvirt seems to use this by default.
Create a guestmount, assuming the guest machine is 'vm_to_test':
$ mkdir -p ~/guestmount/13376
$ sshfs -o direct_io vm_to_test:/ ~/guestmount/13376
Inject the guest perf.data file into the host perf.data file:
Note, due to the guestmount option, guest object files and debug files will be copied into the build ID cache from the guest machine, with the notable exception of VDSO.
If needed, VDSO can be copied manually in a fashion similar to that used by the perf-archive script.
$ perf inject -i guest-sideband-testing-host-perf.data -o inj --guestmount ~/guestmount --guest-data=guest-sideband-testing-guest-perf.data,13376,0xfffffa6ae070cb20
Show an excerpt from the result. In this case the CPU and time range have been to chosen to show interaction between guest and host when 'uname' is starting to run on the guest machine:
Notes:
- the CPU displayed, [002] in this case, is always the host CPU
- events happening in the virtual machine start with VM:13376 VCPU:003, which shows the hypervisor PID 13376 and the VCPU number
- only calls and errors are displayed i.e. --itrace=ce
- branches entering and exiting the virtual machine are split, and show as 2 branches to/from "0 [unknown] ([unknown])"

NAME
----
perf-kwork - Tool to trace/measure kernel work properties (latencies)
SYNOPSIS
--------
[verse]
'perf kwork' {record}
DESCRIPTION
-----------
There are several variants of 'perf kwork':
'perf kwork record <command>' to record the kernel work
of an arbitrary workload.
'perf kwork report' to report the per kwork runtime.
'perf kwork latency' to report the per kwork latencies.
'perf kwork timehist' provides an analysis of kernel work events.
Example usage:
perf kwork record -- sleep 1
perf kwork report
perf kwork report -b
perf kwork latency
perf kwork latency -b
perf kwork timehist
By default it shows the individual work events such as irq, workqeueu,
including the run time and delay (time between raise and actually entry):
Runtime start Runtime end Cpu Kwork name Runtime Delaytime
(TYPE)NAME:NUM (msec) (msec)

PERF_RECORD_FINISHED_INIT = 82,
Marks the end of records for the system, pre-existing threads in system wide
sessions, etc. Those are the ones prefixed PERF_RECORD_USER_*.
This is used, for instance, to 'perf inject' events after init and before
regular events, those emitted by the kernel, to support combining guest and
host records.
The header is followed by compressed data frame that can be decompressed
into array of perf trace records. The size of the entire compressed event
record including the header is limited by the max value of header.size.
