2013-08-06target-i386: Fix X86CPU error handlingAndreas Färber
Error **errp argument is not for emitting warnings, it means an error has occurred and the caller should not make any assumptions about the state of other return values (unless otherwise documented). Therefore cpu_x86_create() must unref the new X86CPU itself, and pc_new_cpu() must check for an Error rather than NULL return value. While at it, clean up a superfluous NULL check.

2013-07-29pc: limit 64 bit hole to 2G by defaultIgor Mammedov
It turns out that some 32 bit windows guests crash if 64 bit PCI hole size is >2G. Limit it to 2G for piix and q35 by default. User may override default 64-bit PCI hole size by using "pci-hole64-size" property. Examples: -global i440FX-pcihost.pci-hole64-size=4G -global q35-pcihost.pci-hole64-size=4G Reported-by: Igor Mammedov <imammedo@redhat.com>, Signed-off-by: Michael S.

2013-07-07pci: Add root bus parameter to pci_nic_init()David Gibson
At present, pci_nic_init() and pci_nic_init_nofail() assume that they will only create a NIC under the primary PCI root. As we add support for multiple PCI roots, that may no longer be the case. This patch adds a root bus parameter to pci_nic_init() (and updates callers accordingly) to allow the machine init code using it to specify the right PCI root for NICs created by old-style -net nic parameters. NICs created new-style, with -device can of course be put anywhere. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2013-07-04pc: pass PCI hole ranges to GuestsMichael S. Tsirkin
Guest currently has to jump through lots of hoops to guess the PCI hole ranges. It's fragile, and makes us change BIOS each time we add a new chipset. Let's report the window in a ROM file, to make BIOS do exactly what QEMU intends. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2013-06-19pc: Make -no-fd-bootchk stick across boot order changesMarkus Armbruster
Option -no-fd-bootchk asks the BIOS to attempt booting from a floppy even when the boot sector signature isn't there, by setting a bit in RTC CMOS. It was added back in 2006 (commit 52ca8d6a). Two years later, commit 0ecdffbb added monitor command boot_set. Implemented by new function pc_boot_set(). It unconditionally clears the floppy signature bit in CMOS. Commit e0f084bf added -boot option once to automatically change the boot order on first reset. Reuses pc_boot_set(), thus also clears the floppy signature bit. Commit d9346e81 took care to preserve this behavior. Thus, -no-fd-bootchk applies to any number of boots. Except it applies just to the first boot with -boot once, and never after boot_set. Weird. Make it stick instead: set the bit according to -no-fd-bootchk in pc_boot_set().
