No changes were necessary, but since I noticed "die" wasn't defined I removed usages of it. Test: python3 ./tools/kconfig_xml_fixup.py --input android-5.15/android-base-conditional.xml --output-matrix ./outputmatrix --output-version ./outputversion Bug: 203436762 Change-Id: I7a94c57c88b96aba393655151cc5e872953dee6e

# The format of the kernel configs in the framework compatibility matrix
|
|
# has a couple properties that would make it confusing or cumbersome to
|
|
# maintain by hand:
|
|
#
|
|
# - Conditions apply to all configs within the same <kernel> section.
|
|
# The <kernel> tag also specifies the LTS version. Since the entire
|
|
# file in the kernel/configs repo is for a single kernel version,
|
|
# the section is renamed as a "group", and the LTS version is
|
|
# specified once at the top of the file with a tag of the form
|
|
# <kernel minlts="x.y.z" />.
|
|
# - The compatibility matrix understands all kernel config options as
|
|
# tristate values. In reality however some kernel config options are
|
|
# boolean. This script simply converts booleans to tristates so we
|
|
# can avoid describing boolean values as tristates in hand-maintained
|
|
# files.
|
