ipchain__fprintf_graph() casts the number of hits in a branch as an
int, which means we lose its highests bits.This results in meaningless number of callchain hits in perf.data
that have a high number of hits recorded, typically those that have
callchain branches hits appearing more than INT_MAX. This happens
easily as those are pondered by the event period.Reported-by: Nick Piggin

Since the libdwfl library before 0.148 fails to analyze live kernel debuginfo,
'perf probe --list' compiled with those old libdwfl sometimes crashes.To avoid that bug, perf probe does not use libdwfl's live kernel analysis
routine when it is compiled with older libdwfl.Side effect: perf with older libdwfl doesn't support listing probe in modules
with source code line. Those could be shown by symbol+offset.Cc: 2nddept-manager@sdl.hitachi.co.jp

This was broken since link(2) doesn't dereference symbolic
links. Instead 'filename' becomes a symbolic link to the same file
that 'name' refers to.This had the bad effect to create dangling symlinks in the case that
even can't be removed with perf-buildid-cache(1).LKML-Reference:

On ARM, module symbol start address is ahead of kernel symbol start address, so
we can't suppose that the start address of kernel map always is zero, otherwise
may cause incorrect .start and .end of kernel map (caused by fixup) when there
are modules loaded, then map_groups__find may return incorrect map for symbol
query.This patch always figures out the start address of kernel map from
/proc/kallsyms if the file is available, so fix the issues on ARM for module
loaded case.This patch fixes the following issues on ARM when modules are loaded:
- vmlinux symbol can't be found by kallsyms maps doing 'perf test'
- module symbols are parsed mistakenlly when doing 'perf top'/'perf report'Cc: Ian Munsie

At least on ARM, padding is inserted between rb_node and sym in struct
symbol_name_rb_node, causing "((void *)sym) - sizeof(struct rb_node)" to
point inside rb_node rather than to the symbol_name_rb_node. Fix this
by converting the code to use container_of().Cc: Ian Munsie

The 59365d1 commit, even being reverted by 33e0d57, showed a non robust
behavior in 'perf record': it really should just warn the user that some
functionality will not be available.The new behavior then becomes:
[acme@felicio linux]$ ls -la /proc/{kallsyms,modules}
-r-------- 1 root root 0 Nov 22 12:19 /proc/kallsyms
-r-------- 1 root root 0 Nov 22 12:19 /proc/modules
[acme@felicio linux]$ perf record ls -R > /dev/null
Couldn't record kernel reference relocation symbol
Symbol resolution may be skewed if relocation was used (e.g. kexec).
Check /proc/kallsyms permission or run as root.

Update usage to reflect the different perf trace variants.
Signed-off-by: Tom Zanussi

Add documentation describing new 'perf trace' command changes
e.g. handling and live-mode/top variants.Signed-off-by: Tom Zanussi
Acked-by: Arnaldo Carvalho de Melo -
This patch attempts to make the perf trace command-line for live-mode
commands more user-friendly and consistent with other perf commands.The main change it makes is to allow to be run as part of
perf trace live-mode commands, as other perf commands do, instead of
the system-wide traces they're currently hard-coded to by the shell
scripts.With this patch, the following live-mode trace now works as expected:
$ perf trace rw-by-pid ls -al
The previous system-wide behavior for this command would still be
available by explicitly specifying -a:$ perf trace rw-by-pid -a ls -al
and if no is specified, the output is also system-wide:
$ perf trace rw-by-pid
Because live-mode requires both record and report steps to be invoked,
it isn't always possible to know which args to send to the report and
which to send to the record steps - mainly this is the case for report
scripts with optional args - in those cases it would be necessary to
use separate 'perf trace record' and 'perf trace report' steps.For example:
$ perf trace syscall-counts ls
Here we can't decide whether ls should be passed as a param to the
syscall-counts script or whether we should invoke ls as a .
In these cases, we just say that we'll ignore optional script params
and always interpret the extra arguments as a .If the user instead wants the other interpretation, that can be
accomplished by using separate record and report commands explicitly:$ perf trace record syscall-counts
$ perf trace report syscall-counts lsSo the rules that this patch implements, which seem to make the most
intuitive sense for live-mode commands:- for commands with optional args and commands with no args, no args
are sent to the report script, all are sent to the record step- for 'top' commands i.e. that end with 'top', can't be
used - all extra args are send to the report script as params- for commands with required args, the n required args are taken to be
the first n args after the script name and sent to the report
script, and the rest are sent to the record stepSigned-off-by: Tom Zanussi
Acked-by: Arnaldo Carvalho de Melo -
Because the perf-trace shell scripts hard-coded the use of the
perf-record system-wide param, a perf trace record session was always
system wide, even if it was given a command.If given a command, perf trace record now only records the events for
the command, as users expect.If no command is given, or if the '-a' option is used, the recorded
events are system-wide, as before.root@tropicana:~# perf trace record syscall-counts ls -al
