Subject: [PATCH 0/4] powerpc32: use cacheable alternatives of memcpy and memset
Date: Tue, 12 May 2015 15:32:47 +0200 (CEST) [thread overview]
Message-ID: <cover.1431436210.git.christophe.leroy@c-s.fr> (raw)
This patchset implements use of cacheable versions of memset and
memcpy when the len is greater than the cacheline size and the
destination is in RAM.
On MPC885, we observe a 7% rate increase on FTP transfer
Christophe Leroy (4):
Partially revert "powerpc: Remove duplicate cacheable_memcpy/memzero
functions"
powerpc32: swap r4 and r5 in cacheable_memzero
powerpc32: memset(0): use cacheable_memzero
powerpc32: memcpy: use cacheable_memcpy
