This patch series is based on Eugenio's fix for handling CVQs in a different ASID [0]. The first patch is the actual fix. The next 2 patches are fixing a possible issue that I found while implementing patch 1. The patches are ordered like this for clarity.

Future AMD SVM supports a new feature called flush by ASID. The idea is to allow CPU to flush TLBs associated with the ASID assigned to guest VM. So hypervisor doesn''t have to reassign a new ASID in order to flush guest''s VCPU. Please review it.

Today, mlx5_vdpa gets started by preallocate 1:1 DMA mapping at device creation time, while this 1:1 mapping will be implicitly destroyed when the first .set_map call is invoked. Everytime when the .reset callback is invoked, any mapping left behind will be dropped then reset back to the initial 1:1 DMA mapping. In order to reduce excessive memory mapping cost during live migration, it is

In order to reduce needlessly high setup and teardown cost of iotlb mapping during live migration, it's crucial to decouple the vhost-vdpa iotlb abstraction from the virtio device life cycle, i.e. iotlb mappings should be left intact across virtio device reset [1]. For it to work, the on-chip IOMMU parent device should implement a separate .reset_map() operation callback to restore 1:1 DMA

Hi All: This series tries to add the support for control virtqueue in vDPA. Control virtqueue is used by networking device for accepting various commands from the driver. It's a must to support multiqueue and other configurations. When used by vhost-vDPA bus driver for VM, the control virtqueue should be shadowed via userspace VMM (Qemu) instead of being assigned directly to Guest. This is

Attached patch for svm will enable a tlb flush for each vmrun. Applies cleanly to 8781:dcc2beb8a1d2 Signed-off-by: Tom Woller <thomas.woller@amd.com> _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Devices with on-chip IOMMU may need to restore iotlb to 1:1 identity mapping from IOVA to PA. Before vhost-vdpa is going away, give them a chance to clean up and reset iotlb back to 1:1 identify mapping mode. This is done so that any vdpa bus driver may start with 1:1 identity mapping by default. Signed-off-by: Si-Wei Liu <si-wei.liu at oracle.com> --- drivers/vhost/vdpa.c | 17

The subject says it all really, I''m pretty sure the system and bios are NUMA aware but I''m not sure if it''s enabled? Is it supported in 3.2.1 stable?

The old virt-v2v code ignored boot kernels with names like "/boot/vmlinuz-*.rpmsave". The transscribed code did not because the Str module requires ‘|’ to be escaped as ‘\|’. This changes the code to use PCRE and fixes it. --- v2v/linux_bootloaders.ml | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/v2v/linux_bootloaders.ml b/v2v/linux_bootloaders.ml index

Regards trying to install vmware-server and the libs problem just read on the vmware tech site that i need to install the 32 bit libs the app to function i have then tried to do yum install xorg-x11- devel.i386 but this fails on a transaction error any way to get this working ? -Stephen

...uru's... Here is my question. 1. Asterisk PBX - 5 Trunks / Incoming lines 2. 1 Building - 3 Companies (sharing phone system) Ok that's the basic layout. Here's the low down - Each company will have one dedicated channel for there company. The other 2 channels they want to be set aside as rollover's (rotary). That is not an issue. Where my concern is, how can I specify if they call Company A and primary line is busy and it rolls over to one of the spare lines, how do I designate which Auto Attendant is played. If it was certain channels set aside for certain companies that...
