0sim-trace
This is intended as a debugging tool for the simulator (initially). It is a
very simplified implementation of
kutrace. Currently, it debugs
the host, not the simulated workload.
The kernel-side implementation is in kernel/zerosim-trace.c in the 0sim
repo, with hooks inserted on the x86-64 syscall, interrupt, fault, and
task-switching code paths in the kernel.
