You +can find more documentation on IOshark at : +https://docs.google.com/a/google.com/document/d/1Bhq7iNPVc_JzwRrkmZqcPjMvWgpHX0r3Ncq-ZsRNOBA/edit?usp=sharing + +The short summary of what IOshark is : IOshark has 2 components, one +is a strace compiler that takes straces fed into it and compiles this +into bytecodes (stored in *.wl files). The compiler runs on a Linux +host. The second component (which runs on the device) is the tester +that takes as input the bytecode files (*.wl files) and executes them +on the device. + +How to Run : +---------- +- First collect straces and compile these into bytecodes. The wrapper +script provided (collect-straces.sh) collects straces, ships them to +the host where the script runs, compiles and packages up the bytecode +files into a wl.tar file. +- Ship the wl.tar file and the iostark_bench binaries to the target +device (on /data/local/tmp say). Explode the tarfile. +- Run the tester. "ioshark_bench *.wl" runs the test with default +options. Supported ioshark_bench options : +-d : Preserve the delays between successive filesystem syscalls as +seen in the original straces. +-n <N> : Run for N iterations +-t <N> : Limit to N threads. By default (without this option), IOshark +will launch as many threads as there are input files, so 1 thread/file.
