2010-10-20pci/bridge: fix pci_bridge_reset()Isaku Yamahata
The lower bits of base/limit registers is RO and shouldn't be zero cleared on reset. This patch fixes it. In fact, the default value of base/limit registers aren't specified in the spec. And some bridges disable forwarding on reset instead of zeroing base/limit registers. So introduce one function to disable bridge forwarding so that such bridges can use it. It will be used later.

2010-09-20pci: implement RW1C register framework.Isaku Yamahata
Implement RW1C register framework. With this patch, it would be easy to implement W1C(Write 1 to Clear) register by just setting w1cmask. Later RW1C register will be used by pcie. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2010-09-13pci: don't ignore invalid parameter for pci_register_bar().Isaku Yamahata

2010-09-13pci: sorting out type confusion in pci_register_bar().Isaku Yamahata
This patch sorts out invalid use of pcibus_t. In pci_register_bar(), pcibus_t wmask is used. It should, however, be uint64_t because it is used to set pci configuration space value(PCIDevice::wmask) by pci_set_quad() or pci_set_long().

2010-07-22pci/bridge: split out pci bridge code into pci_bridge.c from pci.cIsaku Yamahata

2010-07-12target-sh4: Split the LDST macro into 2 sub-macrosAlexandre Courbot
The LDST macro is used to generate ldc and stc instructions that work with a specific register. However, the SGR register only supports stc up to SH4A, which supports both stc and ldc. This patch creates two sub-macros named LD and ST that handle generating ldc and stc instructions separately, and redeclares LDST to use these sub-macro.

2010-07-11virtio-net: correct packet length mathMichael S. Tsirkin
We were requesting too much when checking buffer length: size already includes host header length. Further, we should not exit if we get a packet that is too long, since this might not be under control of the guest. Just drop the packet. Red Hat bz 591494 Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2010-07-11AppleSMC device emulationAlexander Graf
Intel Macs have a chip called the "AppleSMC" which they use to control certain Apple specific parts of the hardware, like the keyboard background light. That chip is also used to store a key that Mac OS X uses to decrypt binaries. This patch adds emulation for that chip, so we're getting one step further to having Mac OS X run natively on Qemu.

2010-07-11pci: set PCI multi-function bit appropriately.Isaku Yamahata
Set PCI multi-function bit according to multifunction property. PCI address, devfn ,is exported to users as addr property, so users can populate pci function(PCIDevice in qemu) at arbitrary devfn. It means each function(PCIDevice) don't know whether pci device (PCIDevice[8]) is multi function or not. So this patch allows user to set multifunction bit via property and checks whether multifunction bit is set correctly.
