These steps seem insufficient. Initially, it failed complaining about a
missing config so I created the directory manually and copied the
confing in only to have it fail again:
lkp-tests/filters/need_kconfig_hw.rb:11:in `load_kernel_context':
context.yaml doesn't exist:
/pkg/linux/x86_64-rhel-8.3-func/gcc-11/f683b9d613193362ceb954c216f663a43c027302/context.yaml
Is there a full set of instructions for recreation?
Thanks,
Liam
