According to commit 01d6c48a82
("Documentation: kselftest:
"make headers" is a prerequisite"), running the kselftests requires
to run "make headers" first.
Do that in "vmtest.sh" as well to fix the HID CI.

Usage: $0 [-i] [-s] [-d <output_dir>] -- [<command>]
|
|
|
|
<command> is the command you would normally run when you are in
|
|
the source kernel direcory. e.g:
|
|
|
|
$0 -- ./tools/testing/selftests/hid/hid_bpf
|
|
|
|
If no command is specified and a debug shell (-s) is not requested,
|
|
"${DEFAULT_COMMAND}" will be run by default.
|
|
|
|
If you build your kernel using KBUILD_OUTPUT= or O= options, these
|
|
can be passed as environment variables to the script:
|
|
|
|
O=<kernel_build_path> $0 -- ./tools/testing/selftests/hid/hid_bpf
|
|
|
|
or
|
|
|
|
KBUILD_OUTPUT=<kernel_build_path> $0 -- ./tools/testing/selftests/hid/hid_bpf
|
|
|
|
Options:
|
|
|
|
-u) Update the boot2container script to a newer version.
|
|
-d) Update the output directory (default: ${OUTPUT_DIR})
|
|
-j) Number of jobs for compilation, similar to -j in make
|
|
(default: ${NUM_COMPILE_JOBS})
|
|
-s) Instead of powering off the VM, start an interactive
|
|
shell. If <command> is specified, the shell runs after
|
|
the command finishes executing
