The memory relating guest domain should be allocated from NUMA node on which the guest runs. Because the latency of the same NUMA node is faster than that of a different one. This patch fixes memory allocation for Address Translation Structure of VT-d. VT-d uses two types of Structures for DMA address translation. The one is Device Assignment Structure. The other is Address Translation

I've been using the NVidia drivers and recently managed to get Nouveau working. Well almost working. Running the command: xrandr -s 640x480 results in a desktop that spans the monitor but leaves black bands of about a third of the screen on the top and bottom. This results in an unreadable display playing games like Lbrickbuster2. I'd like the display to fill the screen. To confirm

On Xen-3.3.0, domain0 Megaraid SAS (SAS 1068 controller) driver is not loading correctly if vtd support in Xen is enabled. It fails at the point of initializing firmware. I wasn''t seeing this error with Xen-3.2.2-rc3 (Unstable version), though with vtd disabled in Xen-3.3.0, it is working. Looks like a degrade problem. Any clues? Thx, Venkat

Hi, I''ve added some preliminary support for VT-d for paravirtualized guests. This must be enabled using an ''iommu_pv'' boot parameter (disabled by default). I''ve added some python bindigs to allow xend to assign PCI devices to IOMMU for PV guests. For HVM guests this is handled in ioemu. Not sure if it makes sense to handle both cases in one place. The

Hi, Keir, These patches are rebased version of Yunhong''s original patches, which were sent out before XEN 3.2 was released. These patches enable MSI support and limited MSI-X support in XEN. Here is the original description of the patches from Yunhong''s mail. The basic idea including: 1) Keep vector global resource owned by xen, while split pirq into per-domain

My Booking model has: serialize :custom_data, Hash From the console it works as expected saving values to the custom_data attribute. But when having a form with parameters like this: booking[custom_data][hello] and creating a new object in the controller like this: Booking.new( params[:booking] ), values are saved in the database with added metadata like this: ---

Fixes made in version 2: 1) Use PML4[257] for ioremap of PCI mmcfg. As full 16-bit segment support would require 44-bits. Since each slot only has 39-bits, we support 2048 PCI segments for now. This can be easily expanded if deemed necessary in the future. 2) Integrated PCI mmcfg access with existing PCI config interface for x86_64. Use MMCFG interface if offset is greater than 256.

Some programs like btrfsck should not be run on a mounted filesystem. This patch adds a check in btrfs_open_devices() for the mount status of every device belonging to the filesystem. The function check_mount() gets improved support for loopback devices. It now detects if the program is run on the file that is being used by the loopback device. Signed-off-by: Andi Drebes

Hi, I just ran into what seems to be an issue on re-invites. I'm not sure if it's a bug or as designed, so I thought I'd ask the question. Here's my setup: - Asterisk 1.8.13.0 - Phone A: Polycom ip331, only allowed to use ulaw, canreinvite=yes - Phone B: Polycom ip330, only allowed to use alaw, canreinvite=yes Phone A calls the extension of phone B. After the normal call setup

Hi, Keir, This patch will move reading and writing of PCI configuration spaces from dom0 to Xen. It also changes VTD code, so that they can touch the PCI configuration spaces with proper lock. This will also benefit MSI support in Xen. Can you give some comments? Thanks! <<pci_conf_xen.patch>> Best Regards Haitao Shan _______________________________________________ Xen-devel

Hi, all, The attached patches try to improve the current FLR logic. The idea is: removing the FLR logic from hypervisor and adding the improved logic in Control Panel. The current FLR logic in hypervisor has some issues: 1) Dstate transition is not guaranteed to properly clear the device state; 2) the current code for PCIe FLR is actually buggy: PCI_EXP_DEVSTA_TRPND doesn''t mean the
