Subject: [GIT PULL] perf/core for v2.6.33
Linus,
Please pull the latest perf-core-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git perf-core-for-linus
Perf events, tools/perf/ and tracepoints development activity has gone
through the roof in this cycle, with 469 commits done by 47 developers:
251 files changed, 21092 insertions(+), 6102 deletions(-)
Here are some of the highlights:
- New 'perf kmem' tool for SLAB analysis. 'perf kmem record' records
the trace, 'perf kmem' reports the result.
- New 'perf probe' tool to utilize kprobes to dynamically probe kernel
functions and insert new events. A 'perf probe my_function' command
will create a new probe at that function and the function name can be
used as a symbolic event ID in all perf tools from that point on. For
example, to probe 'sys_open', do:
$ perf probe sys_open
and it can be used for stats, profiling and tracing from that point
on, in the rest of the perf tools:
$ perf stat -e probe:sys_open_0 -a sleep 1
$ perf record -e probe:sys_open_0 -c 1 -a -f sleep 1
$ perf record -g -e probe:sys_open_0 -c 1 -a -f sleep 1
$ perf top -e probe:sys_open_0
Part of this is a feature to kprobes that uses an instruction decoder
on x86 to make sure that probes inserted by user-space are safe
(occur at the right instruction boundary). The last thing we want is
for instrumentation to crash the kernel.
There's also a new matching ftrace plugin for kprobes.
- New 'perf bench' tool to run micro-benchmarks in a uniform way - next
to the tools that can measure them. It includes three benchmark
modules as a starting point:
perf bench sched
messaging: Benchmark for scheduler and IPC mechanisms
pipe: Flood of communication over pipe() between two processes
perf bench mem
memcpy: Simple memory copy in various ways
Our hope is that people find this useful and start adding more
modules.
- New hardware breakpoints abstraction and support. This allows mixed
use of hw-breakpoints by gdb and perf (and other debugging
facilities). It also allows and implements new features like the
profiling of kernel data variables on stock kernels. For example, to
profile tasklist_lock accesses:
$ perf record -e mem:0x$(grep tasklist_lock /proc/kallsyms | cut -d' ' -f1) -c 1 -a -f sleep 10
[ perf record: Woken up 2 times to write data ]
[ perf record: Captured and wrote 2.157 MB perf.data (~94233 samples) ]
$ perf report

- build-id support for reliable matching of symbols to instrumentation
data.
- Much rewamped and improved ELF symbol resolution code.
- 'perf top' now displays user symbols too mixed with kernel symbols,
and other improvements.
- "--filter expression" support to tracepoints - which utilizes the
filter engine within the kernel. For example, to trace only timer
interrupts in the system:
$ perf record -e irq:irq_handler_entry --filter='irq==0' -R -f -a sleep 10
$ perf trace
perf-27426 [000] 22435.320805: irq_handler_entry: irq=0 name=timer
perf-27426 [000] 22435.321803: irq_handler_entry: irq=0 name=timer
swapper-0 [000] 22435.324797: irq_handler_entry: irq=0 name=timer
swapper-0 [000] 22435.325752: irq_handler_entry: irq=0 name=timer
swapper-0 [000] 22435.328669: irq_handler_entry: irq=0 name=timer
swapper-0 [000] 22435.328850: irq_handler_entry: irq=0 name=timer
Or to only record IRQ 19 when the 'achi' handler is triggered:
$ perf record -e irq:irq_handler_entry --filter='irq==19 && name==ahci' -R -f -a sleep 10
The filtering happens when the event occurs - i.e. events that are
filtered out do not enter the ring-buffer and dont get sent to the
trace file. This allows significant reduction of data traffic.
- Perl scripting engine for programmable 'perf trace' scripting.
See perf trace -g/--gen-script and perf trace -s/--script.
- dwarf info support
- new tracepoints: for PowerPC, signals and elsewhere
- much improved 'perf trace' support
- better structured and extensible perf.data format
- ... and much more.
(See the shortlog and the tree for more details.)
Thanks,
Ingo
