Keir: This is to to make the IDE device model multithreading so that the VMX domain IO access completion (triggering DMA operation) can be asynchronize with the completion of DMA operation. With this patch we get 8%--14% performance gain for kernel build. Thanks, eddie Yang, Xiaowei wrote: > Originally in qemu when a IDE dma transfer is started which is > triggered by access to 0xc000

Keir, This patch fixes cirrus and rt8139 co-exist issue in new qemu-dm.

Keir, The patch moves ACPI timer to HV, which is the last platform timer in Qemu. We found Vista polls ACPI timer very frequently (about 15 times averagely) when handling timer (RTC @ 64HZ) interrupt routine. Though the exact reason is known, it should be related to system time adjustment. When it''s in Qemu, the overhead is big. After moving, Vista''s idle overhead decreases

Package: xen-hypervisor-4.0-amd64 Version: 4.0.1-5.2 Severity: important Tags: patch I have a system based on a Supermicro X8DTH-i motherboard and a Xeon E5506 CPU. It was previously running Debian lenny with xen-hypervisor-3.2-1-amd64 / linux-image-2.6.26-2-xen-amd64 without incident.

IORESOURCE_MEM_DRIVER_MANAGED currently uses an unused PnP bit, which is always set to 0 by hardware. This is far from beautiful (and confusing), and the bit only applies to SYSRAM. So let's move it out of the bus-specific (PnP) defined bits. We'll add another SYSRAM specific bit soon. If we ever need more bits for other purposes, we can steal some from "desc", or

With the .end() accessor having become optional and noting that several of the accessors'' behavior really depends on the result of msi_maskable_irq(), the splits the MSI IRQ chip type into two - one for the maskable ones, and the other for the (MSI only) non-maskable ones. At once the implementation of those methods gets moved from io_apic.c to msi.c. Signed-off-by: Jan Beulich

Hi How can I build out PV driver with PV Dom0 for hvm? I remember it can work with older dom0(2.6.18), but with PV dom0 now, it fails. best regards yang _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

This a step forward to fix the security hole introduced by dom0''s 1:1 mapping VT-d table: remove the critical code and data from it. The more flexible solution is to update dom0''s VT-d table on demand as what will be done for other PV domains. However, there could bring a performance issue even with software optimization. Iotlb flush of some hardware is time-consuming.
