Hi everyone, It's a very minor point, but could we ensure that eigen and La.eigen return a *matrix* for the "vectors" component of the list by including a "drop = FALSE", as specified in the help file, ie put list(values = z$values[ord], vectors = if (!only.values) z$vectors[, ord, drop = FALSE]) Thanks, Jonathan. --please do not edit the information

Hello List, I have a small problem with the ring when transferring blocks the id on the response is different from the request. This is the boot up read, count 0. The guest requests block 0, it has to be located at 7c00. I go ahead and create a REQUEST with this data: ring_req = RING_GET_REQUEST(priv,priv->req_prod_pvt); ring_req->id = 9; ring_req->nr_segments=1; ring_req->operation

Hi all. We developped a pv-scsi driver that we refered Fujita-san''s scsi-driver and blkback. (see, http://www.xensource.com/files/xensummit_4/Xen_Summit_8_Matsumoto.pdf) The pv-scsi driver''s feature is as follow: * Guest has dedicated SCSI-HBAs of Dom0. * Guest can send scsi_cdb to the HBAs. * Guest recognises the HBAs from hostno of xenstore. Currentlly, We are

We already have the frame (pfn of the grant page) stored inside struct grant, so there's no need to keep an aditional list of mapped frames for a specific request. This reduces memory usage in blkfront.

This patch implements persistent grants for the xen-blk{front,back} mechanism. The effect of this change is to reduce the number of unmap operations performed, since they cause a (costly) TLB shootdown. This allows the I/O performance to scale better when a large number of VMs are performing I/O. Previously, the blkfront driver was supplied a bvec[] from the request queue. This was granted to
