DESCRIPTION="Debug tools for AMD Zen systems: s2idle, BIOS, P-State and TTM"

# amd-s2idle, amd-pstate and amd-bios read x86-only interfaces (the AMD PMC
# driver, amd-pstate, the ACPI FADT low-power-idle bit); there is no AMD Zen
# arm64 platform for them to run on.
KEYWORDS="~amd64"
IUSE="systemd"

# pyproject lists cysystemd and dbus-fast as hard dependencies, but upstream
# imports both lazily and falls back: kernel.py tries cysystemd, then
# python-systemd, then dmesg; common.py tries dbus-fast, then dbus-python, for
# the logind reboot. cysystemd is not packaged, so USE=systemd maps to
# python-systemd, the second rung of the same journal fallback. Without it the
# kernel log comes from dmesg, which is also what a non-systemd host uses.
