perf machine: Protect the machine->threads with a rwlock
...
In addition to using refcounts for the struct thread lifetime
management, we need to protect access to machine->threads from
concurrent access.
That happens in 'perf top', where a thread processes events, inserting
and deleting entries from that rb_tree while another thread decays
hist_entries, that end up dropping references and ultimately deleting
threads from the rb_tree and releasing its resources when no further
hist_entry (or other data structures, like in 'perf sched') references
it.
So the rule is the same for refcounts + protected trees in the kernel,
get the tree lock, find object, bump the refcount, drop the tree lock,
return, use object, drop the refcount if no more use of it is needed,
keep it if storing it in some other data structure, drop when releasing
that data structure.
I.e. pair "t = machine__find(new)_thread()" with a "thread__put(t)", and
"perf_event__preprocess_sample(&al)" with "addr_location__put(&al)".
The addr_location__put() one is because as we return references to
several data structures, we may end up adding more reference counting
for the other data structures and then we'll drop it at
addr_location__put() time.

perf timechart: Support using -f to override perf.data file ownership
...
Enable perf timechart to use perf.data when it is not owned by current
user or root.
Example:
# perf timechart record ls
# chown Yunlong.Song:Yunlong.Song perf.data
# ls -al perf.data
-rw------- 1 Yunlong.Song Yunlong.Song 5471744 Apr 2 15:15 perf.data
# id
uid=0(root) gid=0(root) groups=0(root),64(pkcs11)
Before this patch:
# perf timechart
File perf.data not owned by current user or root (use -f to override)
# perf timechart -f
Error: unknown switch `f'
usage: perf timechart [<options>] {record}
-i, --input <file> input file name
-o, --output <file> output file name
-w, --width <n> page width
--highlight <duration or task name>
highlight tasks. Pass duration in ns or process name.
-P, --power-only output power data only
-T, --tasks-only output processes data only
-p, --process <process>
process selector. Pass a pid or process name.
--symfs <directory>

-n, --proc-num <n> min. number of tasks to print
-t, --topology sort CPUs according to topology
--io-skip-eagain skip EAGAIN errors
--io-min-time <time>
all IO faster than min-time will visually appear longer
--io-merge-dist <time>
merge events that are merge-dist us apart
As shown above, the -f option does not work at all.
After this patch:
# perf timechart

# perf timechart -f
Written 0.0 seconds of trace to output.svg.

perf tools: Check recorded kernel version when finding vmlinux
...
Currently vmlinux_path__init() only tries to find vmlinux file from
current directory, /boot and some canonical directories with version
number of the running kernel. This can be a problem when reporting old
data recorded on a kernel version not running currently.
We can use --symfs option for this but it's annoying for user to do it
always. As we already have the info in the perf.data file, it can be
changed to use it for the search automatically.
Before:
$ perf report
...
# Samples: 4K of event 'cpu-clock'
# Event count (approx.): 1067250000
#
# Overhead Command Shared Object Symbol
# ........ .......... ................. ..............................
71.87% swapper [kernel.kallsyms] [k] recover_probed_instruction
After:
# Overhead Command Shared Object Symbol
# ........ .......... ................. ....................
71.87% swapper [kernel.kallsyms] [k] native_safe_halt
This requires to change signature of symbol__init() to receive struct
perf_session_env *.
