2016-07-20	crypto: vmx - Fix aes_p8_xts_decrypt build failure	Herbert Xu	1	-2/+0
	We use _GLOBAL so there is no need to do the manual alignment, in fact it causes a build failure. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2016-07-19	crypto: vmx - Adding asm subroutines for XTS	Paulo Flabiano Smorigo	1	-2/+1863
	This patch add XTS subroutines using VMX-crypto driver. It gives a boost of 20 times using XTS. These code has been adopted from OpenSSL project in collaboration with the original author (Andy Polyakov <appro@openssl.org>). Signed-off-by: Leonidas S.

2015-08-18	crypto: vmx - Fixing AES-CTR counter bug	Leonidas Da Silva Barbosa	1	-17/+17
	AES-CTR is using a counter 8bytes-8bytes what miss match with kernel specs. In the previous code a vadduwm was done to increment counter. Replacing this for a vadduqm now considering both cases counter 8-8 bytes and full 16bytes.

2015-03-12	linux-next: Tree for Mar 11 (powerpc build failure due to vmx crypto code)	Herbert Xu	1	-10/+0
	crypto: vmx - Fix assembler perl to use _GLOBAL Rather than doing things by hand for global symbols to deal with different calling conventions we already have a macro _GLOBAL in Linux to handle this.

2015-02-28	crypto: vmx - Add support for VMS instructions by ASM	Leonidas S. Barbosa	1	-0/+1940
	OpenSSL implements optimized ASM algorithms which support VMX instructions on Power 8 CPU. These scripts generate an endian-agnostic ASM implementation in order to support both big and little-endian. - aesp8-ppc.pl: implements suport for AES instructions implemented by POWER8 processor. - ghashp8-ppc.pl: implements support for GHASH for Power8. - ppc-xlate.pl: ppc assembler distiller. These code has been adopted from OpenSSL project in collaboration with the original author (Andy Polyakov <appro@openssl.org>). Signed-off-by: Leonidas S.
