Subject: [PATCH v2 0/3] MdePkg: add ARM/AARCH64 support to BaseMemoryLib
Date: Tue, 6 Sep 2016 15:23:30 +0100 [thread overview]
Message-ID: <1473171813-24595-1-git-send-email-ard.biesheuvel@linaro.org> (raw)
This adds ARM and AARCH64 support to both BaseMemoryLib (generic C) and
BaseMemoryLibOptDxe (accelerated). The former can be used anywhere, the
latter only in places where the caches are guaranteed to be on, not only
due to the unaligned accesses but also due to the fact that it uses
DC ZVA instructions for clearing memory (AArch64 only).
Ard Biesheuvel (3):
MdePkg/BaseMemoryLib: widen aligned accesses to 32 or 64 bits
MdePkg/BaseMemoryLibOptDxe: add accelerated ARM routines
MdePkg/BaseMemoryLibOptDxe: add accelerated AARCH64 routines
