LKP tools would help to create this directory, and your host already had this according to the listed file you post previously

not clear why you cannot create cpio under ~/.lkp/cache dir

According  to the log you attached, trinity didn't run due to the lkp-src.cgz(lkp-x86_64-ad88cb1a437a_xxx.cgz) haven't be merged into the runtime rootfs.

50M		simple boot test in rootfs debian
1G              plan to run a number of different tests
100G or more    IO tests

Please enter a dir with enough disk space, or simply press Enter to accept the default.
You may still symlink /home/lizhijian/.lkp to a more suitable place in future.
