VPD ECC support Added methods/interfaces to create ECC and verify the data using ECC Tested: tested some of the EEPROMS on Rainier simics root@rainier:/tmp# ./ipz-read-vpd --file /sys/devices/platform/ahb/ahb:apb/ahb:apb:bus@1e78a000/1e78a480.i2c-bus/i2c-8/8-0050/8-00500/nvmem PASSED root@rainier:/tmp# ./ipz-read-vpd --file /sys/devices/platform/ahb/ahb:apb/ahb:apb:bus@1e78a000/1e78a400.i2c-bus/i2c-7/7-0050/7-00500/nvmem PASSED root@rainier:/tmp# ./ipz-read-vpd --file /sys/devices/platform/ahb/ahb:apb/ahb:apb:bus@1e78a000/1e78a480.i2c-bus/i2c-8/8-0051/8-00510/nvmem PASSED root@rainier:/tmp# ./ipz-read-vpd --file /sys/devices/platform/ahb/ahb:apb/ahb:apb:bus@1e78a000/1e78a400.i2c-bus/i2c-7/7-0051/7-00510/nvmem PASSED root@rainier:/tmp# ./ipz-read-vpd --file /sys/devices/platform/ahb/ahb:apb/ahb:apb:bus@1e78a000/1e78a080.i2c-bus/i2c-0/0-0051/0-00510/nvmem PASSED Signed-off-by: Alpana Kumari <alpankum@in.ibm.com> Change-Id: I863327f504c2dfa468d5ceadce10250292a968b7
#Overview This repository hosts code for OpenPower and IBM IPZ format VPD parsers. Both OpenPower VPD and IPZ VPD formats are structured binaries that consist of records and keywords. A record is a collection of multiple keywords. More information about the format can be found here.
The repository consists of two distinct applications, which are:
This is a build-time YAML driven application that parses the OpenPower VPD format and uses the YAML configuration (see extra-properties-example.yaml and writefru.yaml) to determine:
The application instance must be passed in the file path to the VPD (this can, for example, be a sysfs path exposed by the EEPROM device driver) and also the D-Bus object path(s) that EEPROM data needs to be published under.
This parser is can be built by passing in the --enable-ibm-parser
configure option. This parser differs from the OpenPower VPD parser in the following ways:
#
and are > 255 bytes in length).Making the application runtime JSON driven allows us to support multiple systems (with different FRU configurations) to be supported in a single code image as well as making the application more flexible for future improvements.
