With the ccw ipl code sometimes an error message like "virtio: trying to map MMIO memory" or "Guest moved used index from %u to %u" appeared. Turns out that the ccw bios did not zero out the vring, which might cause stale values in avail->idx and friends, especially on reboot. Lets zero out the relevant fields. To activate the patch we need to rebuild s390-ccw.img as well.

- SeaBIOS (bios.bin) is the successor of pc bios. See http://www.seabios.org/ for more information. - The VGA BIOS and the Cirrus VGA BIOS come from the LGPL VGA bios project (http://www.nongnu.org/vgabios/). - The PowerPC Open Hack'Ware Open Firmware Compatible BIOS is available at http://perso.magic.fr/l_indien/OpenHackWare/index.htm. - OpenBIOS (http://www.openbios.org/) is a free (GPL v2) portable firmware implementation. The goal is to implement a 100% IEEE 1275-1994 (referred to as Open Firmware) compliant firmware. The included images for PowerPC (for 32 and 64 bit PPC CPUs), Sparc32 and Sparc64 are built from OpenBIOS 1.1 release (SVN revision 1136). - SLOF (Slimline Open Firmware) is a free IEEE 1275 Open Firmware implementation for certain IBM POWER hardware. The sources are at https://github.com/aik/SLOF, and the image currently in qemu is built from git tag qemu-slof-20130430. - sgabios (the Serial Graphics Adapter option ROM) provides a means for legacy x86 software to communicate with an attached serial console as if a video card were attached. The master sources reside in a subversion repository at http://sgabios.googlecode.com/svn/trunk. A git mirror is available at git://git.qemu.org/sgabios.git. - The PXE roms come from the iPXE project. Built with BANNER_TIME 0. Sources available at http://ipxe.org. Vendor:Device ID -> ROM mapping: 8086:100e -> pxe-e1000.rom 8086:1209 -> pxe-eepro100.rom 1050:0940 -> pxe-ne2k_pci.rom 1022:2000 -> pxe-pcnet.rom 10ec:8139 -> pxe-rtl8139.rom 1af4:1000 -> pxe-virtio.rom - The S390 zipl loader is an addition to the official IBM s390-tools package. That fork is maintained in its own git repository at: git://repo.or.cz/s390-tools.git - The sources for the Alpha palcode image is available from: git://repo.or.cz/qemu-palcode.git
