For PowerKVM hosts, the device-tree exposed by the OPAL firmware is present at /proc/device-tree. We find the device specific vital product data listed in linux at /proc/device-tree/vpd. Here we are making hwinfo display more of unexposed vpd information on PPC hosts. This patch exposes following device properties: ccin - Custom Card Identification Number fru-number - Field Replaceable Unit Number ibm,loc-code - location code(s) for the Field Replacable Unit serial-number - 12 characters serial number (8 characters in old format) part-number - part number description - device description The output will be something like: ... 36 @01 vpd name "vpd", model "", dtype "", compat "ibm,opal-v3-vpd" ccin "", fru-number "", location-code "U8286.42A.10D6CFT", serial-number "", part-number "," description "" 37 @36 vpd/root-node-vpd@a000 name "root-node-vpd", model "", dtype "", compat "" ccin "", fru-number "", location-code "U8286.42A.10D6CFT", serial-number "", part-number "," description "" 38 @37 vpd/root-node-vpd@a000/system-vpd@1c00 name "system-vpd", model "", dtype "", compat "" ccin "", fru-number "", location-code "U8286.42A.10D6CFT", serial-number "", part-number "," description "" 39 @37 vpd/root-node-vpd@a000/root-node-vpd@a001 name "root-node-vpd", model "", dtype "", compat "" ccin "", fru-number "", location-code "U8286.42A.10D6CFT", serial-number "", part-number "," description "" 40 @37 vpd/root-node-vpd@a000/enclosure@1e00 name "enclosure", model "", dtype "", compat "" ccin "2CD4", fru-number "00E1962", location-code "U78C9.001.WZS007X", serial-number "YL30UF39H00M", part-number "00E3352," description "System planar 2S4U" 41 @40 vpd/root-node-vpd@a000/enclosure@1e00/service-processor@200 name "service-processor", model "", dtype "", compat "" ccin "2CD4", fru-number "00E1962", location-code "U78C9.001.WZS007X-P1", serial-number "YL30UF39H00M", part-number "00E3352," description "System planar 2S4U" ...

For PowerKVM hosts, the device-tree exposed by the OPAL firmware is present at /proc/device-tree.
We find the device specific vital product data listed in linux at /proc/device-tree/vpd.
Here we are making hwinfo display more of unexposed vpd information on PPC hosts.
This patch exposes following device properties:
ccin - Custom Card Identification Number
fru-number - Field Replaceable Unit Number
ibm,loc-code - location code(s) for the Field Replacable Unit
serial-number - 12 characters serial number (8 characters in old format)
part-number - part number
description - device description
The output will be something like:
...
