Subject: [PATCH 0/5] Update DSCR tests
Date: Tue,  7 Mar 2023 11:55:10 +1100	[thread overview]
Message-ID: <20230307005515.174362-1-bgray@linux.ibm.com> (raw)

The randomness based DSCR tests currently have a low probability of doing
any writes to the DSCR, making them inefficient in uncovering bugs.

This series adds lockstep variants to these RNG tests, to ensure the happy
path is always tested, and improves the randomness and size of the RNG
tests.

It also removes many iterations of the sysfs DSCR test, allowing the default
timeout to be re-enabled.
