* perf record: Simplify perf_record__writeArnaldo Carvalho de Melo2013-12-19
| | | | | | | | | | | | | | | | | | | | | | | | | 1. Since all callers either test if it is less than zero or assign its result to an int variable, convert it from ssize_t to int; 2. There is just one use for the 'session' variable, so use rec->session directly instead; 3. No need to store the result of perf_data_file__write, since that result is either 'size' or -1, the later making the error result to be stored in 'errno' and accessed thru printf's %m in the pr_err call.

Since we have dso__read_binary_type_filename() and the values this field receives are all DSO__BINARY_TYPE_<FOO> we may as well call it "binary_type" for consistency sake. It also seems more appropriate since it determines if we can do operations like annotation and DWARF unwinding, that needs more than just the symtab, requiring access to ELF text segments, CFI ELF sections, etc. Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/n/tip-2lkbqrn23uc2uvnn9w9in379@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Vince Weaver reports that, on all architectures apart from ARM, PERF_EVENT_IOC_PERIOD doesn't actually update the period until the next event fires. This is counter-intuitive behaviour and is better dealt with in the core code. This patch ensures that the period is forcefully reset when dealing with such a request in the core code. A subsequent patch removes the equivalent hack from the ARM back-end.
