[PATCH] qemu-xen: Intel GPU passthrough, fix OpRegion mapping.
The OpRegion shouldn''t be mapped 1:1 because the address in the host can''t be used in the guest directly. This patch traps read and write access to the opregion of the Intel GPU config space (offset 0xfc). To work correctly this patch needs a change in hvmloader. HVMloader will allocate 2 pages for the OpRegion and write this address on the config space of the Intel GPU. Qemu

[Bridge] No UDP NFS over bridges in Linux 2.6.16.x?
Hi, I have 2 servers which are connected to a gateway machine. The gateway and one server are running Linux 2.6.16.2, while the third machine is running 2.6.16.5. The two ethernet ports on the gateway which are connected to the servers are combined into a single ethernet bridge device. Ever since 2.6.16, I have noticed that I can no longer cross-mount the two servers' /home directories via

[Bridge] [PATCH net-next V5 00/14] Add basic VLAN support to bridges
This series of patches provides an ability to add VLANs to the bridge ports. This is similar to what can be found in most switches. The bridge port may have any number of VLANs added to it including vlan 0 priority tagged traffic. When vlans are added to the port, only traffic tagged with particular vlan will forwarded over this port. Additionally, vlan ids are added to FDB entries and become

[PATCH net-next] net: make ndo_get_stats64 a void function
The network device operation for reading statistics is only called in one place, and it ignores the return value. Having a structure return value is potentially confusing because some future driver could incorrectly assume that the return value was used. Fix all drivers with ndo_get_stats64 to have a void function. Signed-off-by: Stephen Hemminger <sthemmin at microsoft.com> ---
