Connor O'Brien ab51dca9e6 libtimeinstate: initialize current freq before starting tracking ... Currently, our BPF programs start with no knowledge of current CPU frequency and tracking cannot begin for a cluster until a frequency transition happens & makes this information available. On cuttlefish, CPU frequency never changes, so tracking never starts & cuttlefish can't be used for testing this feature. To resolve this, pass the BPF programs initial frequency information read from the scaling_cur_freq sysfs nodes. Test: libtimeinstate_test passes on cuttlefish Test: confirm that uid_time_in_state BPF map contains data on cuttlefish Bug: 138317993 Signed-off-by: Connor O'Brien <connoro@google.com> Change-Id: I5b24c1311e1b58b73c7e32f41c2d99c5ab344549		2020-02-19 14:26:16 -08:00
