[PATCH v2 14/14] selftests/nolibc: tinyconfig: add support for 32/64-bit powerpc

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Firstly, add extra config files for powerpc, powerpc64le and powerpc64.

Second, QEMU_TIMEOUT is configured as 60 seconds for powerpc to allow
quit qemu-system-ppc even if poweroff fails. In normal host machine, ~20
seconds may be enough for boot+test+poweroff, but 60 seconds is used
here to gurantee it at least finish even in a very slow host machine or
the host machine is too busy. Both powerpc64le and powerpc64 can
poweroff normally, no need to configure QEMU_TIMEOUT for them.

It is able to use tinyconfig as the minimal config target to speed up
the run target of powerpc:

    $ for arch in powerpc powerpc64 powerpc64le; do \
        rm -rf $PWD/kernel-$arch; \
        mkdir -p $PWD/kernel-$arch; \
        make tinyconfig run XARCH=$arch O=$PWD/kernel-$arch | grep status ; \
      done

rerun with architecture specific run.out (for later report):

    $ for arch in powerpc powerpc64 powerpc64le; do \
        mkdir -p $PWD/kernel-$arch; \
        make rerun XARCH=$arch O=$PWD/kernel-$arch RUN_OUT=$PWD/run.$arch.out | grep status ; \
      done

report:

    $ for arch in powerpc powerpc64 powerpc64le; do \
        make report RUN_OUT=$PWD/run.$arch.out | grep status ; \
      done
