2016-04-27perf tools: Set the maximum allowed stack from ↵Arnaldo Carvalho de Melo
/proc/sys/kernel/perf_event_max_stack There is an upper limit to what tooling considers a valid callchain, and it was tied to the hardcoded value in the kernel, PERF_MAX_STACK_DEPTH (127), now that this can be tuned via a sysctl, make it read it and use that as the upper limit, falling back to PERF_MAX_STACK_DEPTH for kernels where this sysctl isn't present.

2015-11-06perf bpf: Improve BPF related error messagesWang Nan
A series of bpf loader related error codes were introduced to help error reporting. Functions were improved to return these new error codes. Functions which return pointers were adjusted to encode error codes into return value using the ERR_PTR() interface. bpf_loader_strerror() was improved to convert these error messages to strings. It checks the error codes and calls libbpf_strerror() and strerror_r() accordingly, so caller don't need to consider checking the range of the error code. In bpf__strerror_load(), print kernel version of running kernel and the object's 'version' section to notify user how to fix his/her program. v1 -> v2: Use macro for error code. Fetch error message based on array index, eliminate for-loop. Print version strings.

2015-09-02perf tools: Always use non inlined file name for 'srcfile' sort keyAndi Kleen
When profiling the kernel with the 'srcfile' sort key it's common to "get stuck" in include. For example a lot of code uses current or other inlines, so they get accounted to some random include file. This is not very useful as a high level categorization. For example just profiling the idle loop usually shows mostly inlines, so you never see the actual cpuidle file. This patch changes the 'srcfile' sort key to always unwind the inline stack using BFD/DWARF. So we always account to the base function that called the inline. In a few cases include is still shown (for example for MSR accesses), but that is because they get inlining expanded as part of assigning to a global function pointer. For the majority it works fine though. v2: Use simpler while loop. Add maximum iteration count.

2015-08-10perf tools: Support full source file paths for srclineAndi Kleen
For perf report/script srcline currently only the base file name of the source file is printed. This is a good default because it usually fits on the screen. But in some cases we want to know the full file name, for example to aggregate hits per file. In the later case we need more than the base file name to resolve file naming collisions: for example the kernel source has ~70 files named "core.c" It's also useful as input to post processing tools which want to point to the right file. Add a flag to allow full file name output. Add an option to perf report/script to enable this option.

2015-05-08perf probe: Support glob wildcards for function nameMasami Hiramatsu
Support glob wildcards for function name when adding new probes. This will allow us to build caches of function-entry level information with $params. e.g. ---- # perf probe --no-inlines --add 'kmalloc* $params' Added new events: probe:kmalloc_slab (on kmalloc* with $params) probe:kmalloc_large_node (on kmalloc* with $params) probe:kmalloc_order_trace (on kmalloc* with $params) You can now use it in all perf tools, such as: perf record -e probe:kmalloc_order_trace -aR sleep 1 # perf probe --list probe:kmalloc_large_node (on kmalloc_large_node@mm/slub.c with size flags node) probe:kmalloc_order_trace (on kmalloc_order_trace@mm/slub.c with size flags order) probe:kmalloc_slab (on kmalloc_slab@mm/slab_common.c with size flags) ---- Signed-off-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Ananth N Mavinakayanahalli <ananth@in.ibm.com> Cc: David Ahern <dsahern@gmail.com> Cc: Hemant Kumar <hemant@linux.vnet.ibm.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/20150508010335.24812.19972.stgit@localhost.localdomain Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
