7.1.2.2 GetDIB()
The processor PECI client implementation of GetDIB() includes an 8-byte response and
provides information regarding client revision number and the number of supported
domains. All processor PECI clients support the GetDIB() command.
7.1.2.2.1 Command Format
The GetDIB() format is as follows:
Write Length: 0x01
Read Length: 0x08
Command: 0xF7
7.1.2.2.2 Device Info
The Device Info byte gives details regarding the PECI client configuration. At a
minimum, all clients supporting GetDIB will return the number of domains inside the
package using this field. With any client, at least one domain (Domain 0) must exist.
Therefore, the Number of Domains reported is defined as the number of domains in
addition to Domain 0. For example, if bit 2 of the Device Info byte returns a ‘1’, that
would indicate that the PECI client supports two domains.
