Benchmark feature that currently: - Keeps track of system calls info - Start time - Duration - Capability type - Invocation tag - Log the number of invocations of each system call* - Log the number of invocations for each capability type per syscall. - Has 3 new syscalls (dump, reset, get size). - This new feature uses the existing log buffer (which is 1MiB for x86 and ARM). Since the number of syscall invocations is not deterministic, the logged number of invocations is limited by the size of the buffer. I suggested to enable the users to pass their own user-level buffer, to enable more flexibility, later. - ENABLE_BENCHMARKS is now a parent config option of trace points and system call track features, they can't be used at the same time.
