(See attachment v475.log) Make sure you have CONFIG_VGA_BRIDGE_SETUP set in coreboot. Otherwise, I don't understand why it wouldn't run. (Your logs seem to indicate that optionroms.c:is_pci_vga() is failing - which I think would only happen if CONFIG_VGA_BRIDGE_SETUP isn't set.) > Second i used vgaroms/vgabios.bin as the vgabios name. > The vgabios gets run but i get no display output and SeaBIOS reboots > over and over.

Error booting from USB Storage Device in QEMU-KVM GIT MASTER

Hi, I am unable to boot KVM using a usb flash drive. I'm using QEMU-KVM built from GIT MASTER as of this morning. Here's my QEMU-KVM startup options: qemu-system-x86_64 \ -curses \ -m 512 \ -snapshot \ -device piix3-usb-uhci \ -drive id=usbflash,file=flash.img,if=none,boot=on,cache=writeback \ -device usb-storage,drive=usbflash \ -net nic,macaddr=$(getmacpublic),vlan=0 -net tap,vlan=0,ifname=$publictap,script=no \ -net nic,macaddr=$(getmacprivate),vlan=1 -net tap,vlan=1,ifname=$privatetap,script=no \ $* Here's the debugging output from SeaBIOS.

If the spec says it doesn't return anything, but the acpi code is, it's probably just an error. -Kevin

[RFC] acpi: Do not advertise S3
by Luiz Capitulino 16 Jan '12

16 Jan '12

S3 is broken in qemu in the following ways: 1. S3 is immediately followed by a resume (or it doesn't even take place) 2. The screen goes black after S3 3. Some people reported a hang (I couldn't reproduce it myself) Chances are we can get these bugs fixed for 1.1, until there let's not advertise S3 to prevent things like qemu-ga from breaking qemu.

See for example pc_machine_v0_14 in hw/pc_piix.c, it autosets properties for devices (erroneously called "drivers" in the code). btw, I notice the I/O ports are write only and don't remember their state. I can't think offhand if there's anything bad about it (in fact not having state makes live migration more robust), but perhaps someone else will. -- error compiling committee.c: too many arguments to function

[PATCH 0/4] vgabios Kconfig improvements

Improvements to the Kconfig system. Namely, this series allows the main makefile target to build the vgabios if selected. (Thanks Nils for pointing this out.) It also fixes an issue causing the PCI vendor id and device id to often not be populated. -Kevin Kevin O'Connor (4): vgabios: Improve vgabios Kconfig menu. vgabios: Build vgabios by default if enabled in Kconfig. vgabios: Move vgabios Kconfig definitions to vgasrc/Kconfig. vgabios: Make VBE code depend on a config setting.
