# Used to get a list of firmware files needed to update a LTS
|
|||
# linux-firmware package for a backport kernel. For example to
|
|||
# get a list of files for trusty to support the linux-lts-xenial
|
|||
# kernel run:
|
|||
#
|
|||
# debian/list-lts-update-files trusty xenial /path/to/xenial/fwinfo
|
|||
#
|
|||
# This will generate a list of files that satisfy all of these
|
|||
# conditions:
|
|||
#
|
|||
# 1) In the xenial branch of linux-firmware
|
|||
# 2) Not in the trusty branch of linux-firmware
|
|||
# 3) In the specified fwinfo file
|
|||
#
|
|||
# This can be used as a starting point for finding upstream
|
|||
# commits needed to add the missing firmware files.
|

#
|

# The fwinfo file can be omitted, in which case the output is a list
|
|||
# of firmware files in @newbranch but not in @oldbranch.
