[Qemu-devel] [PATCH RFC] tests: Run qtest cases in parallel |
Date: |

Previously all test cases in a category, such as check-qtest-y, are
executed in a single long gtester command. This patch separates each
test into its own make target to allow better parallism.
Signed-off-by: Fam Zheng <address@hidden>

This saves 50% of the time "make check takes" compared to on master
(I use -j8). RFC because I'm not sure if the new gcov usage is correct
with the now much higher level of parallism compared to before.
