- BENCH_SIMTIME() => lfs3_kiwibd_simtime()
- BENCH_SIMRESET() => lfs3_kiwibd_simreset()
- BENCH_SIMPAUSE() => lfs3_kiwibd_simpause()
- BENCH_SIMRESUME() => lfs3_kiwibd_simresume()
- BENCH_RESET() => lfs3_kiwibd_simreset() + BENCH_STACK/HEAP_RESET()
- BENCH_PAUSE() => lfs3_kiwibd_simpause() + BENCH_STACK/HEAP_PAUSE()
- BENCH_RESUME() => lfs3_kiwibd_simresume() + BENCH_STACK/HEAP_RESUME()
This does two things:
1. Adds pause/resume counters to bd counters to make it easier to
exclude operations from the current bench (potentially useful for
seq+disk usage).
2. Exposes bd simtime operations as BENCH_* macros, to make it a bit
easier to interact with simtime without tying all the benches to
kiwibd. (Not that we'll ever probably not use kiwibd, but still).
Also adopted 32-bit counters for stack/heap pause state instead of a
32-bit stack. Not that either are at a risk of overflowing, but better
safe than sorry.
Based on some experience out-of-tree:
- bench_rbyd - Simple rbyd attr/id litmus benchmark
- bench_btree (new) - Simple btree id/name litmus benchmark
- bench_file (new) - Simple file read/write litmus benchmark
- bench_dir (new) - Simple dir read/write/stat litmus benchmark
- bench_wt - Heavy-duty write-throughput benchmark
- bench_rt (new) - Heavy-duty read-throughput benchmark
Benches take a long time to run for useful results, so we probably don't
want to go crazy with them like with the tests.
Honestly, we may want to chop this down to just the
write/read-throughput benches.
