Unaligned Accesses Support
└─>Probe for hardware unaligned access support
In linux kernel since version 6.1.89 (release Date: 2024-04-29)
During boot, the kernel will run a series of tests to determine the
speed of unaligned accesses. This probing will dynamically determine
the speed of unaligned accesses on the underlying system. If unaligned
memory accesses trap into the kernel as they are not supported by the
system, the kernel will emulate the unaligned accesses to preserve the
UABI.
