I am working on some other bugs and perf issues - and while working I noticed that both sparse and Coverity have reported some issues with Xen drivers. Please see attached various bug-fixes that I am proposing for 3.6.

This patch set if my first attempt to make virtio_console usable on s390. To do so, I had to change hvc_console, because s390 has no request_irq and no free_irq. I want to get feedback from the main users of hvc_console before I proceed. The basic idea of this patch set is to remove the calls to request_irq and free_irq and replace them with backend specific callbacks. Please see the

Hi, Here is a patch (on top of the paravirt patch queue) which makes xen guests use the hvc_console.c infrastructure for the console, thereby greatly reducing the amount console code. xvc0 is gone too, hvc0 is used instead. cheers, Gerd -- Gerd Hoffmann <kraxel@suse.de>

Hello, I wants to make a self compiled kernel for my domUs on a debian etch server with Xen 3.1.4 and 2.6.18.8 dom0 kernel. So, I download sources for linux-2.6.26.8, and I enabled all the Xen features : Symbol: HVC_XEN [=y] Symbol: XEN_BALLOON [=y] Symbol: XEN_FBDEV_FRONTEND [=y] Symbol: XEN_SCRUB_PAGES [=y] Symbol: XEN_KBDDEV_FRONTEND [=y] Symbol: XEN_BLKDEV_FRONTEND [=y] Symbol: XEN_NETDEV_FRONTEND [=y] Symbol: XEN [=y] my domu configuration file is : kernel = ''/boot/...

This makes the Xen console just work.

.... I contacted the Grub people, and they seem more interested in creating a native Xen port of Grub than piggybacking the Mini-OS environment usin kexec as I tried. But they need some documentation on the Xen "firmware" to assess the task at least. What could be given to them apart from hvc_xen.c and xen-blkfront.c in the Linux sources? blkif-drivers-explained.txt? For a start, Grub has a Coreboot port, which is ELF, but the Xen 3.2 domain builder refuses to load it saying: xc_dom_parse_elf_kernel: ELF image has no shstrtab -- Thanks, Feri. ___________________________________________...
