KVM: Advertise the bug in memory region destruction as fixed

2009-05-02T17:57:09+00:00

(cherry picked from 1a811b6167089bcdb84284f2dc9fd0b4d0f1899d) Userspace might need to act differently. Signed-off-by: Avi Kivity Signed-off-by: Greg Kroah-Hartman

KVM: Move device assignment logic to common code

2008-10-15T12:25:33+00:00

To share with other archs, this patch moves device assignment logic to common parts. Signed-off-by: Xiantao Zhang Signed-off-by: Avi Kivity

KVM: Device Assignment with VT-d

2008-10-15T12:25:04+00:00

Based on a patch by: Kay, Allen M This patch enables PCI device assignment based on VT-d support. When a device is assigned to the guest, the guest memory is pinned and the mapping is updated in the VT-d IOMMU. [Amit: Expose KVM_CAP_IOMMU so we can check if an IOMMU is present and also control enable/disable from userspace] Signed-off-by: Kay, Allen M Signed-off-by: Weidong Han Signed-off-by: Ben-Ami Yassour Signed-off-by: Amit Shah Acked-by: Mark Gross Signed-off-by: Avi Kivity

KVM: pci device assignment

2008-10-15T08:15:18+00:00

Based on a patch from: Amit Shah This patch adds support for handling PCI devices that are assigned to the guest. The device to be assigned to the guest is registered in the host kernel and interrupt delivery is handled. If a device is already assigned, or the device driver for it is still loaded on the host, the device assignment is failed by conveying a -EBUSY reply to the userspace. Devices that share their interrupt line are not supported at the moment. By itself, this patch will not make devices work within the guest. The VT-d extension is required to enable the device to perform DMA. Another alternative is PVDMA.

KVM: kvmtrace: replace get_cycles with ktime_get v3

2008-10-15T08:15:15+00:00

The current kvmtrace code uses get_cycles() while the interpretation would be easier using using nanoseconds. ktime_get() should give at least the same accuracy as get_cycles on all architectures (even better on 32bit archs) but at a better unit (e.g. comparable between hosts with different frequencies.

KVM: kvmtrace: Remove use of bit fields in kvm trace structure

2008-10-15T08:15:14+00:00

This patch fixes kvmtrace use on big endian systems. When using bit fields the compiler will lay data out in the wrong order expected when laid down into a file. This fixes it by using one variable instead of using bit fields. Signed-off-by: Jerone Young Signed-off-by: Christian Ehrhardt Signed-off-by: Avi Kivity
