HPET disabled by CONFIG_CMDLINE #144

Closed hannesmann closed 1 year ago

hannesmann commented 1 year ago

I have a laptop that needs to use HPET because the TSC is unstable (it's this issue: https://bugzilla.kernel.org/show_bug.cgi?id=216166, Lenovo still hasn't provided a BIOS update). I boot with tsc=unstable clocksource=hpet but this doesn't work on Liquorix because the built-in kernel command line sets hpet=disable. This leaves acpi_pm as the only available clocksource which is apparently slower and less accurate than HPET.

I tried booting with hpet=enable and hpet=force but this doesn't work because hpet=disable can't be reversed (the first option doesn't even seem to exist).

Could hpet=disable be removed from CONFIG_CMDLINE, or a kernel parameter added that would override the default behavior for those that need it?

Next release removes the hpet=disable cmdline. This may affect others badly but if that's the case, I'll figure out a code change instead to only allow HPET as last resort.

Next release will be available with fix in the next few hours, marking as done.
