warning: no previous prototype for 'pm_set_resources_vi'
Hi Timothy,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 69119673bd50b176ded34032fadd41530fb5af21
commit: 70ebe8a48216ae2fda862cae47ff0b8af5b279b9 amdgpu: Enable KFD on POWER systems
date: 7 months ago
config: powerpc-allyesconfig (attached as .config)
compiler: powerpc64-linux-gcc (GCC) 9.3.0
reproduce (this is a W=1 build):
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
git checkout 70ebe8a48216ae2fda862cae47ff0b8af5b279b9
# save the attached .config to linux build tree
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-9.3.0 make.cross ARCH=powerpc
If you fix the issue, kindly add following tag as appropriate
