Subject: [PATCH 6/9] purism/librem_skl: Explicitely enable VMX and Intel
|
|
SpeedStep
|
|
|
|
The VMX feature was enabled by default by the FSP but a different
|
|
FSP might have it disabled, so this ensures that VMX is explicitely
|
|
enabled for the Librem machines. This option however doesn't seem
|
|
to work in the FSP since VMX doesn't actually get enabled but as
|
|
long as the features MSR remains unlocked, it's not critical.
|
|
|
|
Enabling Intel SpeedStep Technology ensures the ACPI tables contain
|
|
the C-states/P-states which are required for the xen-acpi-processor
|
|
module to be loaded. Without it, the Qubes 4.0-rc4 installer will
|
|
complain at boot about modules that could not be loaded.
