[RFC 0/2] virtio: provide a way for host to monitor critical events in the device
As it was discussed recently, there's currently no way for the guest to notify the host about panics. Further more, there's no reasonable way to notify the host of other critical events such as an OOM kill. This short patch series introduces a new device named virtio-notifier which does two simple things: 1. Provide a simple interface for the guest to notify the host of critical

[RFC/PATCHSET 0/3] virtio: Implement virtio pstore device (v4)
Hello, This is another iteration of the virtio-pstore work. I've addressed all comments from Daniel Berrange on the qemu side. * changes in v4) - use qio_channel_file_new_path() (Daniel) - rename to delete_old_pstore_file (Daniel) - convert G_REMOVE_SOURCE to FALSE (Daniel) * changes in v3) - use QIOChannel API (Stefan, Daniel) - add bound check for malcious guests

[RFC 0/3] virtio-iommu: a paravirtualized IOMMU
This is the initial proposal for a paravirtualized IOMMU device using virtio transport. It contains a description of the device, a Linux driver, and a toy implementation in kvmtool. With this prototype, you can translate DMA to guest memory from emulated (virtio), or passed-through (VFIO) devices. In its simplest form, implemented here, the device handles map/unmap requests from the guest. Future

[RFC/PATCHSET 0/3] virtio-pstore: Implement virtio pstore device
Hello, This patchset is a proof of concept of virtio-pstore idea [1]. It has some rough edges and I'm not familiar with this area, so please give me feedbacks and advices if I'm going to a wrong direction. It started from the fact that dumping ftrace buffer at kernel oops/panic takes too much time. Although there's a way to reduce the size of the original data, sometimes I want to

Hello, This is v2 of the virtio-pstore work. In this patchset I addressed most of feedbacks from previous version. Limiting disk size is not implemented yet. * changes in v2) - update VIRTIO_ID_PSTORE to 22 (Cornelia, Stefan) - make buffer size configurable (Cornelia) - support PSTORE_TYPE_CONSOLE (Kees) - use separate virtqueues for read and write - support concurrent async
