Is there a good way to make the "hcall_table_lookup" function more generally available, like "syscall_name" in scripts/python/Perf-Trace-Util/lib/Perf/Trace/Util.py ? It's even simpler than the syscall ID-to-name mapping, because the HCALL codes are constant, unlike syscall IDs which vary between arches. >
Right, but I don't see any other python script for hcalls. So, I thought to add it in the script itself. Let me know if you are planning to add any :) We will move it in a generic module.
