The new variant is primarily used in framework. See: go/ag/5780400 for usage. Also add tests, benchmarks and fix several issues found in SysMemInfo class. New benchmark results are: -------------------------------------------------------------- Benchmark Time CPU Iterations -------------------------------------------------------------- BM_ReadMemInfo_old 7726 ns 7696 ns 90201 BM_ReadMemInfo_new 7554 ns 7525 ns 90358 BM_ZramTotal_old 6446 ns 6406 ns 108361 BM_ZramTotal_new 6529 ns 6488 ns 106545 BM_MemInfoWithZram_old 14485 ns 14412 ns 48492 BM_MemInfoWithZram_new 20572 ns 20459 ns 33438 -------------------------------------------------------------- The reason for BM_MemInfoWithZram_new shows worse numbers is because the new API also tries to find more than 1 zram device (if it exists). The old implementation hard coded everything to "/sys/block/zram0/" Test: libmeminfo_test 1 Bug: 114325007 Bug: 111694435 Change-Id: I246d9e9a54986ee9b2542d1eaac79ecf7310b23a Signed-off-by: Sandeep Patil <sspatil@google.com> |
