35 To compile this driver into the kernel,
36 place the following line in your
37 kernel configuration file:
38 .Bd -ragged -offset indent
39 .Cd "pseudo-device nvmm"
42 Alternatively, to load the driver as a
43 module at boot time, place the following line in
45 .Bd -literal -offset indent
51 driver provides kernel support for hardware-accelerated virtualization.
52 It is made of a generic MI frontend, to which MD backends can be plugged
53 to implement the core virtualization.
59 API to implement hypervisors.
61 The following backends are supported:
62 .Bl -hyphen -compact -offset indent
64 x86-SVM, for x86 AMD CPUs
66 x86-VMX, for x86 Intel CPUs
