2013-08-21pc_piix: Kill pc_init1() memory region argsEduardo Habkost
All callers always use the same values (get_system_memory(), get_system_io()), so the parameters are pointless.

2013-08-21loader: store FW CFG ROM files in RAMMichael S. Tsirkin
ROM files that are put in FW CFG are copied to guest ram, by BIOS, but they are not backed by RAM so they don't get migrated. Each time we change two bytes in such a ROM this breaks cross-version migration: since we can migrate after BIOS has read the first byte but before it has read the second one, getting an inconsistent state. Future-proof this by creating, for each such ROM, an MR serving as the backing store. This MR is never mapped into guest memory, but it's registered as RAM so it's migrated with the guest. Naturally, this only helps for -M 1.7 and up, older machine types will still have the cross-version migration bug. Luckily the race window for the problem to trigger is very small, which is also likely why we didn't notice the cross-version migration bug in testing yet. Signed-off-by: Michael S.

Convert stderr messages calling error_get_pretty() to error_report(). Timestamp is prepended by -msg timstamp option with it. Per Markus's comment below, A conversion from fprintf() to error_report() is always an improvement, regardless of error_get_pretty(). http://marc.info/?l=qemu-devel&m=137513283408601&w=2 But, it is not reasonable to convert them at one time because fprintf() is used everwhere in qemu.

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>
2013-07-07pci: Abolish pci_find_root_bus()David Gibson
pci_find_root_bus() takes a domain parameter. Currently PCI root buses with domain other than 0 can't be created, so this is more or less a long winded way of retrieving the main PCI root bus. Numbered domains don't actually properly cover the (non x86) possibilities for multiple PCI root buses, so this patch for now enforces the domain == 0 restriction in other places to replace pci_find_root_bus() with an explicit pci_find_primary_bus().

2013-07-04pc_piix: cleanup init compat handlingMichael S. Tsirkin
Make sure 1.4 calls 1.5, 1.3 calls 1.4 etc. This way it's enough to add enough new compat hook in a single place in piix. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2013-07-04pc: pass PCI hole ranges to GuestsMichael S. Tsirkin
