# IMPORTANT: all this is still wip and does not work properly yet!
# INFO: based on kernel source tree commit: def3ccfb02e9715ad86a2e26c09ee216ba73b256
#                              from branch: main
# gcc-4.8 required (only available in ubuntu 18.04 and not 20.04): apt-get install gcc-4.8

# patches:
# adjust gcc version to 4.8 - with newer ones it will not compile or work
patch -p1 < /compile/doc/amazon-mt/misc/patches/adjust-gcc-version.patch
# this would only be required for the ggow kernel
#patch -p1 < /compile/doc/amazon-mt/misc/patches/perf-compile-fix.patch
# all other patches are maintained in the tree
