While writing a driver for a device doing lots of DMA I''ve hit an "swiotlb_full()" problem. This surprised me somewhat as I wouldn''t have expected to need the use of the software TLB - it''s a 64 bit capable device on a server with only 2 GB of RAM, and so I''d have expected to be using a hardware TLB. Is this a peculiarity of Xen, or should I be right

This is a cherry pick of two patches that add support for guest paged out frames in the XCP 2.6.32 dom0 patch queue. First patch propagates the ENOENT returned by the hypervisor in the case of a paged out page, all the way up the call chain to the MMAPBATCH_V2 ioctl. The ioctl is mainly used to harvest those return values and retry. The second patch adds retry loops to all backend grant

Also remove unused xenbus_{,un}map_ring(), adjust types, and clean up header inclusion.

Patrick, there following patches fix xenpaging for me. Granttable handling is incomplete. If a page is gone, a GNTST_eagain should be returned to the caller to inidcate the hypercall has to be retried after a while, until the page is available again. Please review.

I was trying to patch Xen 3.2 from the mercurial repository with the MSI patches by Yunhong Jiang given at the bottom of this page : http://lists.xensource.com/archives/html/xen-devel/2007-11/msg00157.html The tree seems to have significantly changed, especially the hvm_irq_dpci_mapping structure in irq.h header file. Are there any updated patches, or can I get a version of Xen from somewhere

This set of patches adds the support for acceleration plugins to the netfront/netback drivers. These plugins are intended to support virtualisable network hardware that can be directly accessed from the guest, bypassing dom0. This is in response to the RFC we posted to xen-devel with an outline of our approach at the end of September. To follow will be another set of patches to provide our

There would seem to be a potential deadlock in the netfront accelerator plugin support. When the configured accelerator changes in xenstore, netfront tries to load the new plugin using request_module(). It does this from a workqueue work item. request_module() will invoke modprobe which in some circumstances (I''m not sure exactly what - I''ve not managed to reproduce it myself)

Hi, I've been driving myself insane with this problem. I have a trellis plot of contours, and I want each level to have something like "z=value" for each one. I can get each one to say z, or each one to say the value (by using as.factor) but not both. Heres an artificial example to show what I mean (as my actual data set is much larger!) x<-c(1,2,3) y<-c(2,4,6)
