|

29 | * The support library is responsible for providing facilities to load
|
---|
30 | * VMM Host Ring-0 code, to call Host VMM Ring-0 code from Ring-3 Host
|
---|
31 | * code, to pin down physical memory, and more.
|
---|
32 | *
|
---|
33 | * The VMM Host Ring-0 code can be combined in the support driver if
|
---|
34 | * permitted by kernel module license policies. If it is not combined
|
---|
35 | * it will be externalized in a .r0 module that will be loaded using
|
---|
36 | * the IPRT loader.
|
---|
37 | *
|
---|
38 | * The Ring-0 calling is done thru a generic SUP interface which will
|
---|
39 | * transfer an argument set and call a predefined entry point in the Host
|
---|
40 | * VMM Ring-0 code.
|
---|
41 | *
|
---|
42 | * See @ref grp_sup "SUP - Support APIs" for API details.
