poking directly at hardware registers
Such luxury! I just spent a couple weeks getting FreeBSD booting in the Firecracker VM and most of my debugging was performed by inserting hlt instructions into the FreeBSD kernel and looking at whether virtual CPU halted or hit a triple fault.
- jsolson 4y agoI take it the Firecrakcer folks haven't built out support for KVM_GUESTDBG_SINGLESTEP yet :)
- aasasd 4y ago> whether virtual CPU halted or hit a triple fault Ah, I see the gentleman works directly in binary.
