Hi all, the implementation of getpagesize() is broken in klibc. klibc uses sysinfo.mem_unit, which linux interpretes as the memory unit all other memory values returned are to be multiplied with. So it's perfectly ok for the linux sysinfo() to return a mem_unit of '1', which is does if the memory available for this machine fits into the counter. For the unbelievers, have a look in

Hi all, this patch updates the ash-port of klibc to that one found in NetBSD-1.6.1 instead of the horribly old one currently used. It's a bit longish (appearently there has been some work done between 1993 and today), but now it's even useable on 64-bit systems :-). Plus I've added some nice-to-have builtins, e.g. printf.

Hi all, I got bored and implemented SCSI passthrough for the virtio-blk driver. Principle is quite simple, just put the missing fields (cdb, sense and status header) on the virtio queue and then call the SG_IO ioctl on the host. So when using '-drive file=/dev/sgXX,if=virtio,format=host_device' you can happily call any sg_XX command on the resulting vdX device. Quite neat, methinks. And

Hi Alex, I've been playing around with VFIO and megasas (of course). What I did now was switching between VFIO and 'normal' operation, ie emulated access. megasas is happily running under VFIO, but when I do an emergency stop like killing the Qemu session the PCI device is not properly reset. IE when I load 'megaraid_sas' after unbinding the vfio_pci module the driver

Hi all, this patchset implements an emulation for the megaraid_sas HBA. It provides emulates an LSI MegaRAID SAS 8708EM2 HBA, ie presenting to the guest a virtual SCSI adapter. Internally it is using aio for read/write requests and either SG_IO or SCSI command emulation for everything else. The reason for choosing the megaraid_sas HBA and not, say, implementing a virtio scsi interface is
