From: Thierry Reding <treding at nvidia.com> Add a new nouveau_pushbuf_kick_fence() function that takes and emits a sync fence FD. The fence FD can be waited on, or merged with other fence FDs, or passed back to the kernel as a prerequisite for a subsequent HW operation. Based heavily on work by Lauri Peltonen <lpeltonen at nvidia.com> Signed-off-by: Thierry Reding <treding at

Hello The current crypto_engine support only ahash and ablkcipher request. My first patch which try to add skcipher was Nacked, it will add too many functions and adding other algs(aead, asymetric_key) will make the situation worst. This patchset remove all algs specific stuff and now only process generic crypto_async_request. The requests handler function pointer are now moved out of struct

Memory mapped and port I/O is currently broken under VMX when the partition is running in VM8086 mode. The reason is that the instruction decoding support uses 32-bit opcode/address decodes rather 16-bit decodes. This patch fixes that. In addition, the patch adds support for the "stos" instruction decoding because this is a frequently used way to clear MMIO areas such as the screen. As

The crypto engine could actually only enqueue hash and ablkcipher request. This patch permit it to enqueue any type of crypto_async_request.
