Subject: [LTP] [PATCH v2 0/3] Fix ADSP074 timeouts
Date: Wed, 14 Sep 2022 15:43:30 +0200 [thread overview]
Message-ID: <20220914134333.13562-1-mdoucha@suse.cz> (raw)
ADSP074 runs dio_sparse with extreme number of children which can result
in severe system overload and random test timeouts simply because
the main test process gets blocked by scheduler for 30+ seconds. Make
io_read() aware of max_runtime and redesign child failure detection to fix
the timeouts.
Also fixes a bug in io_read() which could have caused false negatives.
Martin Doucha (3):
Add tst_validate_children() helper function
Make io_read() runtime-aware
dio_sparse: Fix child exit code
