similar to: [PATCH] ioemu-remote&ioemu: fix libpci error handling.

On 32e, we create one guest, then hotplug attach one NIC to guest, guest can not get IP address via dhcp, guest qemu log shows "libpci read error. No emulation ". Here is the bug entry: One 32e, hotplug attaching VT-d NIC to guest failed. http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1316. -- haicheng _______________________________________________ Xen-devel mailing list

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 am submitting the patch which supports more Capability Structures and Device Specific Registers for passthrough device. In Xen 3.3 unstable, qemu-dm supports Configuration Header, MSI Capability Structure, and MSI-X Capability Structure. But qemu-dm does not support PCI Express Capability Structure, Device Specific Registers, etc (writing them is ignored). To support various I/O devices, I

I assigned FC-HBA to guest domain, but it did not work. FC-HBA seems to write its internal memory which is mapped to host memory space via pci transaction. But there is no mapping in IOMMU''s page table, so that page fault occurs in IOMMU. I think that MMIO resource mapped via p2m table should be mapped via IOMMU''s page table too. In other word, XEN_DOMCTL_memory_mapping

This patch adds the function that reassign page-aligned memory resources, to dom0 linux. The function is useful when we assign I/O device to HVM domain using pci passthrough. When we assign a device to HVM domain using pci passthrough, the device needs to be assigned page-aligned memory resources. If the memory resource is not page-aligned, following error occurs. Error: pci: 0000:00:1d.7:

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

Dear Yagi-san, > I heard from the horse's mouth that the CentOS team is working on the > 100Hz centosplus kernel. I think your request triggered the action :-) > They want make people happy. That sounds nice! This TIPS, CONFIG_HZ=100, is one of FAQs. It will make most of us happy. Now we can get kernel-vm package on dev.centos.org. Is it a test release of the special kernel? I

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

Dear CentOS lovers, Could you consider to include a patch, http://www.psc.edu/networking/projects/hpn-ssh/ for openssh maybe as CentosPlus packages? It has great speed impact for long-distance ( high delay ) transfer. Regards, Yuji Tsuchimoto

Dear CentOS lovers, Is someone interested in the linux-2.6-smarter-relatime.patch for centosplus kernel? This patch solves disk I/O performance dramatically on servers, And recent distributions (fedora9 and later, etc.) and official kernel applies it. RHEL6 may include it, but RHEL5 is not. How about the linux-2.6-smarter-relatime.patch? Best Regards, Yuji
