Hey Rusty, These updated patches in the series return -EFAULT on copy_xx_user errors and also move the copy_from_user into fops_write() instead of it being in send_buf. This enables send_buf to just read from kernel buffers, making it simpler. This also allows write()s to write more to the host in one go, removingthe 4k limitation. I do limit the writes to 32k at once to not put too much

I run latest sparse from git on virtio drivers (turns out the version I had was rather outdated). This patchset fixes a couple of bugs this uncovered, and adds some annotations to make it sparse-clean. In particular, endian-ness is often tricky, so this patchset enabled endian-ness checks for sparse builds. Michael S. Tsirkin (10): virtio_console: drop unused config fields drm/virtio: fix

Hi, this work is based on the virtio_wl driver in the ChromeOS kernel by Zach Reizner, currently at: https://chromium.googlesource.com/chromiumos/third_party/kernel/+/chromeos-4.4/drivers/virtio/virtio_wl.c There's one feature missing currently, which is letting clients write directly to the host part of a resource, so the extra copy in TRANSFER_TO_HOST isn't needed.

Hi all: This series try to share MSIX irq for each tx/rx queue pair. This is done through: - introducing virtio pci channel which are group of virtqueues that sharing a single MSIX irq (Patch 1) - expose channel setting to virtio core api (Patch 2) - try to use channel setting in virtio-net (Patch 3) For the transport that does not support channel, channel paramters were simply ignored.
