From: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com>
Support "$vars" meta argument syntax for tracing all local variables at
probe point.
Now you can trace all available local variables (including function
parameters) at the probe point by passing $vars.
# perf probe --add foo $vars
This automatically finds all local variables at foo() and adds it as
probe arguments.

Peter Zijlstra, Arnaldo Carvalho de Melo
From: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com>
At this point, --fentry (mcount function entry) option for gcc fuzzes
the debuginfo variable locations by skipping the mcount instruction
offset (on x86, this is a 5 byte call instruction).
This makes variable searching fail at the entry of functions which
are mcount'ed.
e.g.)
Available variables at vfs_read
@<vfs_read+0>
(No matched variables)
This patch adds additional location search at the function entry point
to solve this issue, which tries to find the earliest address for the
variable location.
Note that this only works with function parameters (formal parameters)
because any local variables should not exist on the function entry
address (those are not initialized yet).
With this patch, perf probe shows correct parameters if possible;
# perf probe --vars vfs_read
Available variables at vfs_read
@<vfs_read+0>
char* buf
loff_t* pos
size_t count
struct file* file

From: Ingo Molnar <mingo@kernel.org>
Before this patch, looking at 'perf bench sched pipe' behavior over
'top' only told us that something related to perf is running:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
19934 mingo 20 0 54836 1296 952 R 18.6 0.0 0:00.56 perf
19935 mingo 20 0 54836 384 36 S 18.6 0.0 0:00.56 perf
After the patch it's clearly visible what's going on:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
19744 mingo 20 0 125m 3536 2644 R 68.2 0.0 0:01.12 sched-pipe
19745 mingo 20 0 125m 1172 276 R 68.2 0.0 0:01.12 sched-pipe
The benchmark-subsystem name is concatenated with the individual
testcase name.
Unfortunately 'perf top' does not show the reconfigured name, possibly
because it caches ->comm[] values and does not recognize changes to
them?
Also clean up a few bits in builtin-bench.c while at it and reorganize
the code and the output strings to be consistent.
Use iterators to access the various arrays. Rename 'suites' concept to
'benchmark collection' and the 'bench_suite' to 'benchmark/bench'. The
many repetitions of 'suite' made the code harder to read and understand.
The new output is:
comet:~/tip/tools/perf> ./perf bench
Usage:
perf bench [<common options>] <collection> <benchmark> [<options>]
# List of all available benchmark collections:
sched: Scheduler and IPC benchmarks
mem: Memory access benchmarks
numa: NUMA scheduling and MM benchmarks
all: All benchmarks
comet:~/tip/tools/perf> ./perf bench sched
# List of available benchmarks for collection 'sched':
messaging: Benchmark for scheduling and IPC
pipe: Benchmark for pipe() between two processes
all: Test all scheduler benchmarks
comet:~/tip/tools/perf> ./perf bench mem
# List of available benchmarks for collection 'mem':
memcpy: Benchmark for memcpy()
memset: Benchmark for memset() tests
all: Test all memory benchmarks
comet:~/tip/tools/perf> ./perf bench numa
# List of available benchmarks for collection 'numa':
mem: Benchmark for NUMA workloads
all: Test all NUMA benchmarks
Individual benchmark modules were not touched.

Change "struct perf_sched sched" from being global to being local.
The build slowdown cured by f36f83f947ed is dealt with in the following
patch, by programatically setting perf_sched.curr_pid.

builtin-sched.c took a log time to build with -O6 optimization. This
turned out to be caused by:
.curr_pid = { [0 ... MAX_CPUS - 1] = -1 },
Fix by initializing curr_pid programmatically.
This addresses the problem cured in f36f83f947ed using a smaller hammer.
