[PATCH 0/4] powerpc/crypto: IBM Power7+ in-Nest compression support
From: Seth Jennings
Date: Thu Jul 19 2012 - 10:43:27 EST
This is a continuation of support for the Power7+ in-Nest
hardware accelerator.
https://lkml.org/lkml/2012/4/12/223
This patchset adds the hardware driver and the cryptographic
driver for hardware accelerated compression, which uses a
hardware-optimized algorithm named 842.
The hardware driver has limits on generic compression and is
geared toward compressing units that are of PAGE_SIZE for
in-kernel memory compression.
Based on linux-next (20120717)
Seth Jennings (4):
powerpc: nx: rework Kconfig
powerpc: nx: add compression support to arch vec
powerpc: nx: add 842 hardware compression driver
crypto: add 842 crypto driver
