Hello, I'm relatively new to R. I've read the intro guide, but I can't quite figure out how to: I have a function: Jcost <- function (theta, in, out) { a <- output - input %*% theta 1/2 * t(a) %*% a } where "theta" is a 2x1 matrix "in" is a 20x2 matrix "out" is a 20x1 matrix return value is a scaler This works well when I only want to

The OS parses the IORT table to build a map of ID relations between IOMMU and devices. ID Array is used to find correspondence between IOMMU IDs and PCI or platform devices. Later on, the virtio-iommu driver finds the associated LNRO0005 descriptor via the "Device object...

This is the continuation of my proposal for virtio-iommu, the para- virtualized IOMMU. Here is a summary of the changes since last time [1]: * The virtio-iommu document now resembles an actual specification. It is split into a formal description of the virtio device, and implementation notes. Please find sources and binaries at [2]. * Added a probe request to describe to the guest different

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
