PAL_BRAND_INFO procedure calls are used to ascertain the processor branding
Description:
information.
The info_request input argument for PAL_BRAND_INFO describes which processor
branding information is being requested. The info_request values are split into two
categories: architected and implementation-specific. The architected info_request have
values from 0-15. The implementation-specific info_request have values 16 and above.
The architected info_request are described in this document. The
implementation-specific info_request are described in processor-specific documentation.
This call returns the processor brand information as requested with the info_request
argument.

Value
0
All Other Values
This procedure will return an invalid argument if an unsupported info_request argument
is passed as an input or a -6 if the requested information was not available on the
current processor.

Table 11-62 describes the values.
The ASCII brand identification string will be copied to the address specified in the
address input argument. The processor brand identification string is defined to be a
maximum of 128 characters long; 127 bytes will contain characters and the 128th byte
is defined to be NULL (0). A processor may return less than the 127 ASCII characters
as long as the string is null terminated. The string length will be placed in the
brand_info return argument.
