Re: [PATCH -tip 0/6 V4] tracing: kprobe-based event tracer

Hmm, I'd like to know actually kvm aims to emulate all kinds of

We're less interested in fpu/sse. The interesting instructions are those used for page table management, mmio, and real mode execution.


If so, I might find some bugs in x86_emulate.c.
However, I don't know all bugs. To find all of them, we have to
port x86_emulate.c to user-space, decode binaries with it, and
compare its output with another decoder, as Jim had done with insn.c.


That would be very useful.



-- I have a truly marvellous patch that fixes the bug which this signature is too narrow to contain.
