PAL_VP_INFO
PAL_VP_INFO – PAL Virtual Processor Information (50)
Purpose:
Returns information about virtual processor features.
Calling Conv:
Static
Mode:
Physical
Buffer:
Not dependent
Arguments:
Returns:
Status:
Description:
The PAL_VP_INFO procedure call is used to describe virtual processor features.
The
feature_set
input argument for PAL_VP_INFO describes which virtual-processor
feature_set
information is being requested, and is composed of two fields as shown:
A
vmm_id
of 0 indicates architected feature sets, while others are
implementation-specific feature sets. Implementation-specific feature sets are
described in VMM-specific documentation.
This procedure will return a -8 if an unsupported
feature_set
argument is passed as an
input. The return status is used by the caller to know which feature sets are currently
supported on a particular VMM. This procedure always returns unimplemented (-1)
when called on physical processors.
For each valid
feature_set
, this procedure returns information about the virtual processor
in
vp_info
. Additional information may be returned in the memory buffer pointed to by
vp_buffer
, as needed. Details, for a given implementation-specific
feature_set
, of whether
information is returned in the buffer, the size of the buffer, and the representation of
this information in the buffer and in
vp_info
are described in VMM-specific
documentation.
Architected
feature_set
0 (
vmm_id
0,
index
0) is defined and required to be implemented
(if this procedure is implemented), but there are no architected features defined in it
yet, and so all bits in
vp_info
are reserved for architected
feature_set
0. Other architected
feature sets (
vmm_id
0,
index
>0) are undefined, and return -8 (Specified
feature_set
is
not implemented). Software can call PAL_VP_INFO with a
feature_set
argument of 0 to
