[kvm-devel] [PATCH 1/1] direct mmio for passthrough - kernel part

From: Ben-Ami Yassour <[EMAIL PROTECTED]> Enable a guest to access a device's memory mapped I/O regions directly. Userspace sends the mmio regions that the guest can access. On the first page fault for an access to an mmio address the host translates the gva to hpa, and updates the sptes. Signed-

[kvm-devel] [RFC] direct mmio for passthrough

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. We save the list of MMIO regions of the guest's devices and the corresponding host MMIO regions in the host kernel. When
