[PATCH] Memory model: Fix the memory model issues for Linux kernel
by Hanjun Guo 24 Sep '22

24 Sep '22

From: Jonas Oberhauser <jonas.oberhauser(a)huawei.com> This is the update and fixes for memory model, simplify the model by removing redundancies, making semantics of seq-cst explicit, making ppo a subset of po, making ppo locally computable, as well as eliminating several spurious bugs in qspinlock and litmus tests, and ensuring correct compilation to the official power model. These issues were detected by Jonas Oberhauser, Viktor Vafeiadis, and the authors of "Verifying and Optimizing Compact NUMA-Aware Locks on Weak Memory Models", and the solutions are proposed by Jonas Oberhauser and Viktor Vafeiadis.
