Hi Ian/Stefano: I changed over to the PV clock for hybrid liked we talked at the hackathon. I still have the hang in update_wall_time() after dom0 switches to xen as clocksource. The source of hang seems to be in xen stime_local_stamp in cpu_time that suddenly jumps to a large 64bit value. I''ve been chasing to figure where that happens, and why for the hybrid and not PV. It appears the

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.

Introduce a new flag to disable iommu emulation on old iommu systems. This patch is taken from my v4 patch queue, which is till pending, to make old or non-iommu system to run cleanly without interfered by iommuv2 codes. This might be helpful to isolate iommuv2 code in debugging unstable regressions. The reset part of v4 will be re-based. Thanks, Wei Signed-off-by: Wei Wang

These two patches were originally part of the XSM series that I have posted, and remain prerequisites for that series. However, they are independent of the XSM changes and are a useful simplification regardless of the use of XSM. The Acked-bys on these patches were provided before rebasing them over the copyback changes in 26268:1b72138bddda, which had minor conflicts that I resolved. [PATCH

There has been some progress, but still no joy. Definitely not intended for inclusion at this point. Tim, Wei, I added a Xen command line toggle to disable IOMMU and P2M table sharing. Tim, I verified that changes to p2m-pt.c don''t break shadow mode (64bit hypervisor and Win 7 guest). Hongkaixing, I incorporated your suggestion in patch 2, so I should add your Signed-off-by eventually.

Hello xen-devel, I am using xen 4.2.1 and have tried the following with kernel 3.0.0 and 3.2.1. I am trying to invoke the HVMOP_flush_tlbs hypercall but have been unsuccessful. I am basing my call on the functions in in xc_misc.c, trying to guess what is meant by "@arg must be null" in the comment where HVMOP_flush_tlbs is defined. What is the correct way to invoke this

Trying to migrate a 64bit PV guest with 64GB running medium to heavy load on xen 3.4.0, it is showing lot of soft lockups. The softlockups are causing dom0 reboot by the cluster FS. The hardware has 256GB and 32 CPUs. Looking into the hypervisor thru kdb, I see one cpu in sh_resync_all() while all other 31 appear spinning on the shadow_lock. I vaguely remember seeing some thread on this while
