| 2016-07-04 | perf header: Transform nodes string info to struct | Jiri Olsa | 1 | -1/+4 | |
| Storing NUMA info within struct numa_node instead of strings. This way it's usable in future patches. Also it turned out it's slightly less code involved than using strings.

| 2016-02-16 | perf tools: Add perf data cache feature | Jiri Olsa | 1 | -0/+13 | |
| Storing CPU cache details under perf data. It's stored as new HEADER_CACHE feature and it's displayed under header info with -I option: $ perf report --header-only -I ... # CPU cache info: # L1 Data 32K [0-1] # L1 Instruction 32K [0-1] # L1 Data 32K [2-3] # L1 Instruction 32K [2-3] # L2 Unified 256K [0-1] # L2 Unified 256K [2-3] # L3 Unified 4096K [0-3] ... All distinct caches are stored/displayed.

| 2015-12-09 | perf tools: Save cmdline arguments earlier | Josh Poimboeuf | 1 | -9/+0 | |
| perf_env__set_cmdline() only saves the arguments the first time it's called. It doesn't need to be called every time the options and suboptions are parsed. Instead it can just be called once. This also has the advantage of making the option parsing code less perf-specific so it can be moved out to a library.

| 2015-09-14 | perf env: Introduce read_cpu_topology_map() method | Arnaldo Carvalho de Melo | 1 | -0/+28 | |
| Out of the code to write the cpu topology map in the perf.data file header. Now if one needs the CPU topology map for the running machine, one needs to call perf_env__read_cpu_topology_map(perf_env) and the info will be stored in perf_env.cpu. For now we're using a global perf_env variable, that will have its contents freed after we run a builtin. v2: Check perf_env__read_cpu_topology_map() return in write_cpu_topology() (Kan Liang) Cc: Adrian Hunter <[email protected]> Cc: Borislav Petkov <[email protected]> Cc: David Ahern <[email protected]> Cc: Frederic Weisbecker <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Kan Liang <[email protected]> Cc: Namhyung Kim <[email protected]> Cc: Stephane Eranian <[email protected]> Cc: Wang Nan <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]> | |||||
| 2015-09-14 | perf env: Adopt perf_header__set_cmdline | Arnaldo Carvalho de Melo | 1 | -0/+39 | |
| Move this from two globals to perf_env global, that eventually will be just perf_header->env or something else, to ease the refactoring series, leave it as a global and go on reading more of its fields, not as part of the header writing process but as a perf_env init one that will be used for perf.data-less situations.

| 2015-09-14 | perf env: Move perf_env out of header.h and session.c into separate object | Arnaldo Carvalho de Melo | 1 | -0/+19 | |
| Since it can be used separately from 'perf_session' and 'perf_header', move it to separate include file and object, next csets will try to move a perf_env__init() routine.
