LITMUS TESTS
|
|
============
|
|
|
|
Each subdirectory contains litmus tests that are typical to describe the
|
|
semantics of respective kernel APIs.
|
|
For more information about how to "run" a litmus test or how to generate
|
|
a kernel test module based on a litmus test, please see
|
|
tools/memory-model/README.
|
|
|
|
|
|
atomic (/atomic directory)
|
|
--------------------------
|
|
|
|
Atomic-RMW+mb__after_atomic-is-stronger-than-acquire.litmus
|
|
Test that an atomic RMW followed by a smp_mb__after_atomic() is
|
|
stronger than a normal acquire: both the read and write parts of
|
|
the RMW are ordered before the subsequential memory accesses.
|
|
|
|
Atomic-RMW-ops-are-atomic-WRT-atomic_set.litmus
|
|
Test that atomic_set() cannot break the atomicity of atomic RMWs.
|
|
NOTE: Require herd7 7.56 or later which supports "(void)expr".
|
|
|
|
|
|
RCU (/rcu directory)
|
|
--------------------
|
|
|
|
MP+onceassign+derefonce.litmus (under tools/memory-model/litmus-tests/)
|
|
Demonstrates the use of rcu_assign_pointer() and rcu_dereference() to
|
|
ensure that an RCU reader will not see pre-initialization garbage.
|
|
|
|
RCU+sync+read.litmus
|
|
RCU+sync+free.litmus
|
|
Both the above litmus tests demonstrate the RCU grace period guarantee
|
|
that an RCU read-side critical section can never span a grace period.
