The script can run the testsuite for multiple architectures and provides
an overall test report.
Furthermore it can automatically download crosstools from
mirrors.kernel.org if requested by the user.
Example execution:
$ ./run-tests.sh
i386: 162 test(s): 162 passed, 0 skipped, 0 failed => status: success
x86_64: 162 test(s): 162 passed, 0 skipped, 0 failed => status: success
arm64: 162 test(s): 162 passed, 0 skipped, 0 failed => status: success
arm: 162 test(s): 162 passed, 0 skipped, 0 failed => status: success
mips: 162 test(s): 161 passed, 1 skipped, 0 failed => status: warning
ppc: 162 test(s): 162 passed, 0 skipped, 0 failed => status: success
ppc64: 162 test(s): 162 passed, 0 skipped, 0 failed => status: success
ppc64le: 162 test(s): 162 passed, 0 skipped, 0 failed => status: success
riscv: 162 test(s): 162 passed, 0 skipped, 0 failed => status: success
s390: 162 test(s): 161 passed, 1 skipped, 0 failed => status: warning
loongarch: 162 test(s): 161 passed, 1 skipped, 0 failed => status: warning
