crypto: vmx - Adding enable_kernel_vsx() to access VSX instructions

2015-09-29T17:26:05+00:00

commit 2d6f0600b2cd755959527230ef5a6fba97bb762a upstream.

vmx-crypto driver make use of some VSX instructions which are
only available if VSX is enabled. Running in cases where VSX
are not enabled vmx-crypto fails in a VSX exception.

In order to fix this enable_kernel_vsx() was added to turn on
VSX instructions for vmx-crypto.

crypto: vmx - Fixing GHASH Key issue on little endian

2015-09-21T17:05:40+00:00

commit 3c5f0ed78e976be705218cad62acf6a68e9d121e upstream.

GHASH table algorithm is using a big endian key.
In little endian machines key will be LE ordered.
After a lxvd2x instruction key is loaded as it is,
LE/BE order, in first case it'll generate a wrong
table resulting in wrong hashes from the algorithm.

Bug affects only LE machines.
In order to fix it we do a swap for loaded key.

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.

crypto: vmx - Add support for VMS instructions by ASM

2015-02-28T10:13:46+00:00

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 ).
