Subject: [PATCH v3 0/2] efi/arm64: FP/SIMD preserve/restore during UEFI Runtime Services
Date: Fri, 4 Jul 2014 19:41:51 +0200 [thread overview]
Message-ID: <1404495713-10338-1-git-send-email-ard.biesheuvel@linaro.org> (raw)
Two patches to add FP/SIMD preserve/restore to UEFI Runtime Services:
- patch #1 moves runtime services wrappers to generic code so we can reuse them
for arm64
- patch #2 enables the wrappers for arm64 and inserts calls to kernel_neon_begin
and kernel_neon_end
@Matt: please queue up for 3.17
v3:
- improve commit message for patch #2 and add Catalin's ack
v2:
- add Kconfig symbol EFI_RUNTIME_WRAPPERS so we don't break ia64 by enabling it
unconditionally
