Hardware access / accurate CPU emulation


I work on Valgrind, and for some time time the CPU emulation hasn't had much development (except for IBM engineers contributing to PPC and s390).

One of the big problems is being able to reproduce issues. For instance

This seems to have a reasonable patch, but I don't have the hardware to test it (and add a matching regression test).

I see two solutions.

  1. Emulation. Does anyone know if something like qemu does sufficienctly good emulation to be used for something like this?
  2. Access real hardware. Does AMD have any schemes to help FOSS developers like this?
