Wednesday, 19 August 2020

Hi David,

First bad commit (maybe != root cause):

tree:   git://git.kraxel.org/linux drm-qemu-next
head:   9fe2f897499f129f9f0ef4c51a11512dcf2ab7d0
commit: 9fe2f897499f129f9f0ef4c51a11512dcf2ab7d0 [1/1] virtio: fix build for configs
without dma-bufs
config: mips-randconfig-r016-20200818 (attached as .config)
compiler: clang version 12.0.0 (https://github.com/llvm/llvm-project
b34b1e38381fa4d1b1d9751a6b5233b68e734cfe)
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
        # install mips cross compiling tool for clang build
        # apt-get install binutils-mips-linux-gnu
        git checkout 9fe2f897499f129f9f0ef4c51a11512dcf2ab7d0
        # save the attached .config to linux build tree
        COMPILER_INSTALL_PATH=$HOME/0day COMPILER=clang make.cross ARCH=mips 

If you fix the issue, kindly add following tag as appropriate
