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. The root cause is that if two MMIO spaces are continuous, qemu may misuse last MMIO space''s read/write to handle current request.

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

From: "Xiaowei.Hu" <xiaowei.hu at oracle.com> ocfs2_block_group_alloc_discontig() disables chain relink by setting ac->ac_allow_chain_relink = 0 because it grabs clusters from multiple cluster groups. It doesn't keep the credits for all chain relink,but ocfs2_claim_suballoc_bits overrides this in this call trace:

When a domain''s VT-d table is changed, only the iommus under which the domain has assigned devices need to be flushed.

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.

Hi I tried the SSH patch from Anthony.. using the following test code. It seems that it works only once... I mean for executing only one command over the established channel/connection. Any ideas... code from xmlrpclib import Transport from xen.util.xmlrpclib2 import ServerProxy server = ServerProxy("ssh://root@192.168.0.102/RPC2", None, None, 1, 1) l = server.xend.domains(1)

Hi Guys Im trying to complile Asterisk on my new dual Xeon 3.0ghz EM64T machine. Im running Debian 3.1, and have installed the 2.6.8-11-em64t-p4-smp kernel (and headers).
