| 2016-01-11 | perf tools: Fix PowerPC native building | Wang Nan | 1 | -2/+2 | |
| Checks BPF syscall number, turn off libbpf building on platform doesn't correctly support sys_bpf instead of blocking compiling. Reported-and-Tested-by: Naveen N.

| 2015-11-26 | bpf tools: Add helper function for updating bpf maps elements | He Kuang | 1 | -0/+14 | |
| Add bpf_map_update_elem() helper function which calls the sys_bpf syscall to update elements in bpf maps. Upcoming patches will use it to adjust data in map through the perf command line.

| 2015-08-07 | bpf tools: Introduce bpf_load_program() to bpf.c | Wang Nan | 1 | -0/+34 | |
| bpf_load_program() can be used to load bpf program into kernel. To make loading faster, first try to load without logbuf. Try again with logbuf if the first try failed.

| 2015-08-07 | bpf tools: Add bpf.c/h for common bpf operations | Wang Nan | 1 | -0/+51 | |
| This patch introduces bpf.c and bpf.h, which hold common functions issuing bpf syscall. The goal of these two files is to hide syscall completely from user. Note that bpf.c and bpf.h deal with kernel interface only. Things like structure of 'map' section in the ELF object is not cared by of bpf.[ch]. We first introduce bpf_create_map(). Note that, since functions in bpf.[ch] are wrapper of sys_bpf, they don't use OO style naming.
