ARMv8 obsoletes the use of A32 SWP/SWPB instructions such that

they are always undefined. Say Y here to enable software
|
|
|
|
emulation of these instructions for userspace using LDXR/STXR.
|
|
|
|
|
|
|
|
In some older versions of glibc [<=2.8] SWP is used during futex
|
|
|
|
trylock() operations with the assumption that the code will not
|
|
|
|
be preempted. This invalid assumption may be more likely to fail
|
|
|
|
with SWP emulation enabled, leading to deadlock of the user
|
|
|
|
application.
|
|
|
|
|
|
|
|
NOTE: when accessing uncached shared regions, LDXR/STXR rely
|
|
|
|
on an external transaction monitoring block called a global
|
|
|
|
monitor to maintain update atomicity. If your system does not
|
|
|
|
implement a global monitor, this option can cause programs that
|
|
|
|
perform SWP operations to uncached memory to deadlock.
