komorebi-for-kde/nix/ -> nix/linux/ komorebi-for-mac/nix/ -> nix/macos/ The nix expressions of the platforms (modules, option files, VM test suites, kwin effects, the darwin module) sit next to the existing nix/workspace-src.nix. Renames only (252 files); the flakes that import them are replaced by one root flake later in this stack, so nix does not evaluate at this revision.

# A CPU loop that scripts/wsl2-probe.sh times in three places: on the host, in a guest under
|
|
# KVM and in a guest under TCG. busybox's ash runs it, so the same interpreter runs the same
|
|
# instructions everywhere and only the way the CPU is provided differs.
|

#
|
|
# `probe_loop N` counts to N and prints the milliseconds it took, read from /proc/uptime, whose
|
|
# resolution is 10 ms: a loop shorter than about a second says little.
|
|
|
|
# the uptime in centiseconds; the 1 in front of the fraction keeps ash from reading 08 as octal
