processor PECI clients. All command responses are prepended with a completion code
that contains additional pass/fail status information. Refer to
Section 2.5.5.2
for details
regarding completion codes.
Note:
The 2-byte parameter field and 4-byte read data field defined in
Figure 2-10
are sent in standard PECI ordering with LSB
first and MSB last.
2.5.2.4.2
Supported Responses
The typical client response is a passing FCS, a passing Completion Code and valid data.
Under some conditions, the client’s response will indicate a failure.
2.5.2.5
WrPkgConfig()
The WrPkgConfig() command provides write access to the package configuration space
(PCS) within the processor, including various power and thermal management
functions. Typical PCS write services supported by the processor may include power
limiting, thermal averaging constant programming and so on. Refer to
Section 2.5.2.6
for more details on processor-specific services supported through this command.
2.5.2.5.1
Command Format
The WrPkgConfig() format is as follows:
Write Length:
0x0a(dword)

CC: 0x40
Command passed, data is valid.
CC: 0x80
Response timeout. The processor is not able to generate the required response in a timely
fashion. Retry is appropriate.
CC: 0x81
Response timeout. The processor is not able to allocate resources for servicing this
command at this time. Retry is appropriate.
CC: 0x90
Unknown/Invalid/Illegal Request
