# Makefile for the drm device driver.  This driver provides support for the
# Direct Rendering Infrastructure (DRI) in XFree86 4.1.0 and higher.

# Add a set of useful warning flags and enable -Werror for CI to prevent
# trivial mistakes from creeping in. We have to do this piecemeal as we reject
# any patch that isn't warning clean, so turning on -Wall -Wextra (or W=1) we
# need to filter out dubious warnings.  Still it is our interest
# to keep running locally with W=1 C=1 until we are completely clean.
#
# Note the danger in using -Wall -Wextra is that when CI updates gcc we
# will most likely get a sudden build breakage... Hopefully we will fix
# new warnings before CI updates!
