When AArch64 Exclusive Accesses Meet Cacheability

For performance-sensitive AArch64 work, memory access behavior deserves close attention. A discussion of exclusive accesses and cacheability highlights an architecture-specific issue that may matter when investigating why an access does not behave as expected.

Cacheability matters for exclusive accesses

When Ldaxr Doesn't Work examines issues involving exclusive accesses and cacheability on AArch64. For developers working close to memory behavior, the connection offers a specific area to investigate during performance work. Understanding it may help inform memory-management decisions, though the material does not establish a particular speed improvement.
