This patch for PCI passthrough devices enables a guest to access a device's memory mapped I/O regions directly, without requiring the host to trap and emulate every MMIO access.
Updated from last version: we create a memory slot for each MMIO region of the guest's devices, and then use the /sys/bus/pci/.../resource# mapping to find the hfn for that MMIO region. The kernel part and the userspace part of this patchset apply to Amit's pv-dma tree. Tested on a Lenovo M57p with an e1000 NIC assigned directly to an FC8 guest. Comments are appreciated. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
