[kvm-unit-tests PATCH 07/24] riscv: Add run script and unittests.cfg

Andrew Jones
2024-01-24T07:18:37Z

With a run script and a unittests.cfg file we can now run

$ KVM_UNIT_TESTS_ENV=test-env ./run_tests.sh

where test-env has the environment variables needed for both tests.

Note, to change the SBI implementation under test, for example to
RustSBI, QEMU needs the -bios parameter. The full command line
would be

qemu-system-riscv64 -nographic -M virt -cpu rv64 \
-kernel riscv/sbi.flat \
-bios $PATH_TO_RUSTSBI

and with the run script, it's

SBI_IMPL="-bios $PATH_TO_RUSTSBI" ./run_tests.sh -g sbi

(note the '-g sbi' to only run the SBI test group)

Finally, with the addition of the run script, 'make standalone' now
also works.
