# Configure how the Linux checkpatch script should be invoked in the context of

# This is not Linux so don't expect a Linux tree!

# This clarifes the lines indications in the report.
#
# E.g.:
# Without this option, we have the following output:
#      #333: FILE: drivers/arm/gic/arm_gic_v2v3.c:160:
# So we have 2 lines indications (333 and 160), which is confusing.
# We only care about the position in the source file.
#
# With this option, it becomes:
#      drivers/arm/gic/arm_gic_v2v3.c:160:
--showfile

# Don't show some messages like the list of ignored types or the suggestion to
# use "--fix" or report changes to the maintainers.

# Ignore the following message types, as they don't necessarily make sense in
# the context of the TFTF.
#

# The Linux kernel expects the SPDX license tag in the first line of each file.
# We don't follow this convention here.
--ignore SPDX_LICENSE_TAG

# COMPLEX_MACRO generates false positives.
--ignore COMPLEX_MACRO

# TFTF commit messages are expected to have a Gerrit Change-Id.
--ignore GERRIT_CHANGE_ID

# FILE_PATH_CHANGES reports this kind of message:
# "added, moved or deleted file(s), does MAINTAINERS need updating?"
# We do not use this MAINTAINERS file process in TFTF.
--ignore FILE_PATH_CHANGES

# AVOID_EXTERNS reports this kind of messages:
# "externs should be avoided in .c files"
# We don't follow this convention in TFTF.
--ignore AVOID_EXTERNS

# NEW_TYPEDEFS reports this kind of messages:
# "do not add new typedefs"
# We allow adding new typedefs in TFTF.
--ignore NEW_TYPEDEFS

# Avoid "Does not appear to be a unified-diff format patch" message
--ignore NOT_UNIFIED_DIFF

# VOLATILE reports this kind of messages:
# "Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt"
# We allow the usage of the volatile keyword in TFTF.
--ignore VOLATILE
