* Fix loading of ELF multiboot kernelsKevin Wolf2009-12-192-6/+6
| | | | | | | | | | | | | The multiboot implementation assumed that there is only one program header (which contains the entry point) and that the entry point is at the start of the code. This doesn't hold true generally and caused too little data to be loaded. Fix the loading code to pass the whole loaded data to the Multiboot Option ROM.

* S390: Don't tell guest we're updating config spaceAlexander Graf2009-12-181-1/+1
| | | | | | | | | | | | | | Currently we always set the "config space changed" bit to 1 when triggering any virtio interrupt. While that worked in 2.6.27, newer kernels interpret that value as "only the config space changed and nothing else happened". Since we usually trigger interrupts to tell the guest that something did happen, we just not tell it the config space changed for now until we implement the correct callback for that.

* scsi: fix drive hotplug.Gerd Hoffmann2009-12-121-0/+1
| | | | | | | | | | | | | | This patch fills the DriveInfo->unit after hotplugging a scsi disk. It makes a difference when auto-assigning a scsi id, where unit was left filled with '-1' instead of the actual scsi id.

* pci: don't hw_error() when no slot is available.Gerd Hoffmann2009-12-121-2/+9
| | | | | | | | | | | | | Current PCI code will simply hw_error() and thus abort in case no free PCI slot is available or the requested PCI slot is already in use by another device. For the hotplug case this behavior is not acceptable. This patch makes qemu pass up the error properly, so the calling code can decide whenever it wants to exit with an error (on startup) or whenever it wants to continue (hotplug).

* pci: don't abort() when trying to hotplug with acpi off.Gerd Hoffmann2009-12-121-1/+16
| | | | | | | | | | | | The PCI bus on x86 requires ACPI for hotplug support, thus disbling ACPI also disables hotplug for the PCI bus. This patch makes qemu check whenever the PCI bus in question can handle hotplug before trying to add devices. This is needed because qdev will abort() on any attempt to hotplug devices into a non-hotpluggable bus.

* Set default console to virtio on S390xGerd Hoffmann2009-12-122-0/+8
| | | | | | | | | | | | | | | | All "normal" system emulation targets in qemu I'm aware of display output on either VGA or serial output. Our S390x virtio machine doesn't have such kind of legacy hardware. So instead we need to default to a virtio console. Add flags to QEMUMachine to indicate which kind of default devices make sense for the machine in question. Use it for S390x: enable virtcon, disable serial, parallel and vga.

* fix rtc-td-hack on host without high-res timersGleb Natapov2009-12-121-0/+17
| | | | | | | | | | | | | | On hosts without high-res timers it is impossible to inject rtc interrupt faster then 1kHz. Windows sometimes configures RTC to generate 1kHz interrupts, so we can't inject missed interrupts when running on such hosts. Always injecting an interrupt on REG_C read is also not an option since Windows wait for REG_C to become zero with interrupt disabled during boot. This patch uses mixed approach: accelerate timer + inject up to 1000 interrupts on REG_C read.
