Subject: [PATCH RFC memory-model 0/21] LKMM updates for review
Date: Tue, 26 Mar 2019 16:41:14 -0700 [thread overview]
Message-ID: <20190326234114.GA23843@linux.ibm.com> (raw)
Hello!
This series contains LKMM updates:
1. Make scripts be executable.
2. Fix comment in MP+poonceonces.litmus, courtesy of Andrea Parri.
3. Do not use "herd" to refer to "herd7", courtesy of Andrea Parri.
4. Rewrite "KERNEL I/O BARRIER EFFECTS" section of memory-barriers.txt,
courtesy of Will Deacon.
5-6. Make LKMM scripts note timeouts instead of just saying that
the validation was bad.
7. Make LKMM scripts identify litmus-test typos and use of
unsupported primitives instead of just saying that the validation
was bad.
8. Add support for synchronize_srcu_expedited().
9. Make LKMM scripts detect unconditional deadlocks.
10-21. Leverage Boqun Feng's C-to-assembly litmus-test-translation
capability to allow verifying LKMM against hardware models
for checkalllitmus.sh. This is a work in progress.
Thanx, Paul
