2015-05-08perf machine: Protect the machine->threads with a rwlockArnaldo Carvalho de Melo1-2/+3
In addition to using refcounts for the struct thread lifetime management, we need to protect access to machine->threads from concurrent access. That happens in 'perf top', where a thread processes events, inserting and deleting entries from that rb_tree while another thread decays hist_entries, that end up dropping references and ultimately deleting threads from the rb_tree and releasing its resources when no further hist_entry (or other data structures, like in 'perf sched') references it. So the rule is the same for refcounts + protected trees in the kernel, get the tree lock, find object, bump the refcount, drop the tree lock, return, use object, drop the refcount if no more use of it is needed, keep it if storing it in some other data structure, drop when releasing that data structure. I.e. pair "t = machine__find(new)_thread()" with a "thread__put(t)", and "perf_event__preprocess_sample(&al)" with "addr_location__put(&al)". The addr_location__put() one is because as we return references to several data structures, we may end up adding more reference counting for the other data structures and then we'll drop it at addr_location__put() time.

2015-01-21perf mem: Enable sampling loads and stores simultaneouslyStephane Eranian1-23/+100
This patch modifies perf mem to default to sampling loads and stores simultaneously. It could only do one or the other before yet there was no hardware restriction preventing simultaneous collection. With this patch, one run is sufficient to collect both. It is still possible to sample only loads or stores by using the -t option: $ perf mem -t load rec $ perf mem -t load rep Or $ perf mem -t store rec $ perf mem -t store rep The perf report TUI will show one event at a time. The store output will contain a Weight column which will be empty. In V2, we updated the man pages to reflect the change and also simplify the initialization of the argv vector passed to the cmd_*() functions as per LKML feedback. In V3, we fixed typos in the changelog.

2014-08-13perf tools: Check recorded kernel version when finding vmlinuxNamhyung Kim1-1/+1
Currently vmlinux_path__init() only tries to find vmlinux file from current directory, /boot and some canonical directories with version number of the running kernel. This can be a problem when reporting old data recorded on a kernel version not running currently. We can use --symfs option for this but it's annoying for user to do it always. As we already have the info in the perf.data file, it can be changed to use it for the search automatically.
