2012-03-05perf annotate: Handle lower case key code in annotate_browser__run()Namhyung Kim1-0/+2

2012-03-05perf evlist: Restore original errno after open failedNamhyung Kim1-0/+1
If perf_evsel__open() failed, the errno was set and returned properly. However since the perf_evlist__open() called close() on fd's for all of evsel x cpu x thread after the failure, the errno was overridden by other code (EBADF). So the caller of the function ended up seeing different error message and getting confused. Fit it by restoring original return value. Because one of caller of the function is in the python extension, and it uses system errno internally, it'd be better restoring the original value rather than using the return value of the function directly, IMHO (i.e. I'm not a python expert :) Cc: Ingo Molnar <[email protected]> Cc: Paul Mackerras <[email protected]> Cc: Peter Zijlstra <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Namhyung Kim <[email protected]> Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next USB: Gadget: changes for 3.4 This merge is rather big. Here's what it contains: For am5536udc we have just simple coding style fixes. Nothing that has any potential to cause any issues going forward. With mv_udc, there's only one single change removing an unneeded NULL check. at91_udc also only saw a single change this merge window, and that's only removing a duplicated header. The Renesas controller has a few more involved changes. Support for SUDMAC was added, there's now a special handling of IRQ resources for when the IRQ line is shared between Renesas controller and SUDMAC, we also had a bug fix where Renesas controller would sleep in atomic context while doing DMA transfers from a tasklet. There were also a set of minor cleanups. The FSL UDC also had a scheduling in atomic context bug fix, but that's all. Thanks to Sebastian, the dummy_hcd now works better than ever with support for scatterlists and streams. Sebastian also added SuperSpeed descriptors to the serial gadgets. The highlight on this merge is the addition of a generic API for mapping and unmapping usb_requests. This will avoid code duplication on all UDC controllers and also kills all the defines for DMA_ADDR_INVALID which UDC controllers sprinkled around. A few of the UDC controllers were already converted to use this new API. Conflicts: drivers/usb/dwc3/gadget.c
2012-02-29perf probe: Ensure offset provided is not greater than function length ↵Prashanth Nageshappa1-0/+6
without DWARF info too The 'perf probe' command allows kprobe to be inserted at any offset from a function start, which results in adding kprobes to unintended location.

The make_min_config does not take into account when the build fails, resulting in a invalid MIN_CONFIG .config file. When the build fails, it is ignored and the boot test is executed, using the previous built kernel.

2012-02-21perf tools: fix broken perf record -a modeStephane Eranian1-1/+1
The following commit: b52956c perf tools: Allow multiple threads or processes in record, stat, top introduced a bug in the thread_map code which caused perf record -a to not setup system-wide monitoring properly. $ taskset -c 1 noploop 1000 & $ perf record -a -C 1 sleep 10 $ perf report -D | tail -20 cycles stats: TOTAL events: 4413 MMAP events: 4025 COMM events: 340 SAMPLE events: 48 Here I was expecting about 10,000 samples and not 48. In system-wide mode, the PID passed to perf_event_open() must be -1 and it was 0. That caused the kernel to setup a per-process event on PID:0. Consequently, the number of samples captured does not correspond to the requested measurement. The following one-liner fixes the problem for me with or without -C. I would also suggest to change the malloc() to something that matches the struct definition. thread_map->map[] is declared as int map[] and not pid_t map[]. If map[] can only contain pids, then change the struct definition.

2012-02-13perf tools: Get rid of ctype.h in symbol.cNamhyung Kim1-1/+1
The ctype.h in symbol.c was needed because of isupper(). However we now have it in util.h, it can be changed to use our implementation.

2012-02-13perf tools: ctype.c only wants util.hNamhyung Kim1-1/+1
The implementation of sane ctype macros only depends on symbols in util.h not cache.h.

2012-02-13perf tools: Implement islower/isupper macro into util.hNamhyung Kim1-0/+4
The util.h header provides various ctype macros but lacks those two. Add them.

2012-02-13perf tools: Change perf_guest default back to falseJoerg Roedel1-1/+1
Setting perf_guest to true by default makes no sense because the perf subcommands can not setup guest symbol information and thus not process and guest samples. The only exception is perf-kvm which changes the perf_guest value on its own. So change the default for perf_guest back to false.
