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

Hi All, When xm block-detach command was done on PV-ON-HVM, the response of other disks was lost. It is because a wrong event channel was invalidated when detaching it. Not the evtchn number but the irq number is invalidated specifying it.

Hi All, I sent the patch to make blktap work with PV-on-HVM. I corrected the part that had been pointed out in the Xen community. ・All xvdN disk is looked like hdN. ・All tap disks are checked.(tap:aio, tap:sync, tap:vmdk, etc.) We cannot use blktap for the volume of the system with PV-on-HVM and are embarrassed. Could you apply this patch? Or, please give the comment to me. Signed-off-by:

This patchset includes an updated version of the SCSI frontend and backend drivers. The frontend and backend drivers exchange SCSI RDMA Protocol (SRP) messages via a ring buffer. The backend driver sends SCSI commands to the user-space daemon, which performs SCSI commands and I/O operations. The backend driver uses VM_FOREIGN feature like the blktap driver for zero-copy of data pages. Like the

I''ve been having a look through scsifront again, and I saw this bit: ring_req->timeout_per_command = (sc->timeout_per_command / HZ); ring_req->nr_segments = 0; spin_unlock_irq(host->host_lock); scsifront_do_request(info); wait_event_interruptible(info->shadow[ring_req->rqid].wq_reset, info->shadow[ring_req->rqid].wait_reset); in

I have a startup considering building a Java backend and a Rails frontend. The Java backend will take care of creating a caching layer for the database and offer other additional services. The Rails frontend will mostly be for creating the webapp and monitoring tools. What startups/companies out there are using this kind of setup? What are some gotchas in terms of development speed, deployment,

Is anyone working on SCSI passthrough using the ''SCSI Generic'' support under Linux, eg /dev/sgX? This is how VMWare allows a VM to use SCSI devices.

Hello, Andrew > Is the backend the best place to do this or should I attempt to make > llvm-gcc not generate i128 in the first place? It depends whether i128 is a native type for alpha, or not. If it's not - frontend should not generate it. If it's native type then it might be useful just to declare new regclass with virtual 'wide' registers consist of register pairs and

I am seeing i128 from llvm-gcc on Alpha.  I know the calling convention for them, they are split into two registers, but I don't know if that should be handled in the frontend or the backend.  I would just as soon do it in the backend, but I didn't see any support in the new calling convention work for automatically splitting an argument into multiple registers. Is the backend the best
