|
# The purpose of this script is to compile information about the hardware
|
|
# versions of various devices on each unit. This is useful when searching
|
|
# through reported issues for correlations with certain hardware revisions.
|
|
# The information is collected from various locations in proc and sysfs (some
|
|
# of which are product-specific) and compiled into small, single-line text
|
|
# files in the userdata partition, one for each type of device. The format of
|
|
# these lines are as follows:
|
|
#
|
|
# MOTHREV-vX
|
|
# hw_name=XXXXX
|
|
# vendor_id=XXXXX
|
|
# hw_rev=XXXXX
|
|
# date=XXXXX
|
|
# lot_code=XXXXX
|
|
# fw_rev=XXXXX
|
|
# size=XXXXMB
|
|
# (components may also add additional fields to the ones above)
|
|
#
|
|
# The extact format of each field will be device-specific, but should be
|
|
# consistent across a particular hardware platform. Note that each revision
|
|
# data file is rewritten every time this script is called. This ensures that
|
|
# any future format changes to the revision files are picked up.
|
|
#
|
|
# While the method used to read the information should be consistent on a given
|
|
# platform, the specific path to a device's information may vary between
|
|
# products. The hardware_revisions.conf file provides a way to adjust those
|
|
# paths from the default.
