The current release of Whonix is based on Debian bullseye and runs "native" on OpenPOWER KVM-HV using libvirt. All connections within it are forced through Tor, using different paths for different applications additionally, it uses kloak for keystroke anonymization and secure network time synchronization instead of NTP, has higher quality RNGs, and enables AppArmor and hardened kernel profiles to prevent against other types of attacks. (I should point out that all links in this article are "clearnet.") Whonix is a second operating system based on Kicksecure (a Debian derivative formerly known as "Hardened Debian") that runs within VMs on your existing OS (compare with Tails). You can help.ĭeveloper Jeremy Rand wrote in to report his functioning port of Whonix 16 to OpenPOWER. The MVP is little-endian POWER9 Baseline Interpreter and Wasm support, so we're getting closer and closer. Incidentally, I'm about two-thirds of the way through the wasm test cases. Although you'll no longer be YOLOing it on such a system, still remember to echo Y > /sys/kernel/debug/powerpc/dawr_enable_dangerous as root and restart your debugger to pick up hardware watchpoint support. #PALM PILOT EMULATOR MAC UPGRADE#Now that I'm stressing out gdb a lot more working on the Firefox JIT, it turns out that even if you do upgrade your CPUs to DD2.3 (as I did for my dual-8 Talos II system, or what Raptor sells as "v2"), you don't automatically get access to the DAWR even on a fixed POWER9 (Fedora 34). This is rare but catastrophic enough that the option to enable DAWR anyway is hidden behind a debugfs switch. This register functions properly on POWER8 but has an erratum on pre-DD2.3 POWER9 steppings (what Raptor sells as "v1") where the CPU will checkstop - invariably bringing the operating system to a screeching halt - if a watchpoint is set on cache-inhibited memory like device I/O. Way back in Linux 5.2 was a "YOLO" mode for the DAWR register required for debugging with hardware watchpoints.
