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 nvidia.com> --- For the kernel patches that add the new IOCTL, see the series at: https://patchwork.freedesktop.org/series/36361/ includ...

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...

...ly 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 an aside, vmx_platform.c should really reuse x86_emulate.c as much as possible.

vhost-blk is an in-kernel virito-blk device accelerator. Due to lack of proper in-kernel AIO interface, this version converts guest's I/O request to bio and use submit_bio() to submit I/O directly. So this version any supports raw block device as guest's disk image, e.g. /dev/sda, /dev/ram0. We can add file based image support to vhost-blk once we have in-kernel AIO interface.
