Re: [Qemu-discuss] QEMU: DBT vs. Interpretation

Yes, your assumption is right. Every time we execute the same binary and settings (w/o I/O), we get the same instruction trace. The question is whether DBT introduces any source of indeterminism (e.g., arbitrary reordering of instructions in the TB or something that does not violate correctnes

[Qemu-discuss] qemu-system-arm - machines with more than 1 GB RAM?

Hi, I'd like to emulate an armhf platform with at least 2, better 4 or more GB RAM, allthough didn't find one supported by qemu. (most was vexpress-a9 with up to 1 GB) Since out in the wild there are ARM devices like the imx6 with up to 2GB, this seems to be quite odd. Do you have a hint, where t

Hi there! When I was looking around for some documentation on how to get qemu networking I only found guides where bridges and/or VPNs were involved. Since I didn‘t want to read another manpage concerning something I probably won‘t need anywhere else and since I had the time to think about how th
