2010-12-11Make simple io mem handler endian awareAlexander Graf
As an alternative to the 3 individual handlers, there is also a simplified io mem hook function. To be consistent, let's add an endianness parameter there too. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-12-11Add endianness as io mem parameterAlexander Graf
As stated before, devices can be little, big or native endian. The target endianness is not of their concern, so we need to push things down a level. This patch adds a parameter to cpu_register_io_memory that allows a device to choose its endianness. For now, all devices simply choose native endian, because that's the same behavior as before.

2010-07-22pci/bridge: split out pci bridge code into pci_bridge.c from pci.cIsaku Yamahata
Move pci bridge related code into pci_bridge.c from pci.c for further enhancement. pci.c is big enough now, so split it out. No code change but exporting some accesser functions. In fact, few pci bridge functions stays in pci.c. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
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.

2010-07-11pci: don't overwrite multi functio bit in pci header type.Isaku Yamahata
Don't overwrite pci header type. Otherwise, multi function bit which pci_init_header_type() sets appropriately is lost. Anyway PCI_HEADER_TYPE_NORMAL is zero, so it is unnecessary to zero which is already zero cleared. how to test: run qemu and issue info pci to see whether a device in question is normal device, not pci-to-pci bridge.

2009-11-09pci_host.h: move functions in pci_host.h into .c file.Isaku Yamahata
split static functions in pci_host.h into pci_host.c and pci_host_template.h. Later a structures declared in pci_host.h, PCIHostState, will be used. However pci_host.h doesn't allow to include itself easily. This patches addresses it. pci_host.h includes functions which are instantiated in .c by including pci_host.h with typedefing pci_addr_t. pci_addr_t is per pci host bridge and is typedef'ed to uint32_t for ioio or target_phys_addr_t for mmio in .c file. That prevents from including pci_host.h to use PCIHostState because of requiring type, pci_addr_t. Its purpose to include is to instantiate io function for mmio or ioio depending on which pci host bridge requires ioio or mmio. To avoid including code, we always instantiate both version.

2009-10-07New qdev_init_nofail()Markus Armbruster
Like qdev_init(), but terminate program via hw_error() instead of returning an error value. Use it instead of qdev_init() where terminating the program on failure is okay, either because it's during machine construction, or because we know that failure can't happen. Because relying in the latter is somewhat unclean, and the former is not always obvious, it would be nice to go back to qdev_init() in the not-so-obvious cases, only with proper error handling. I'm leaving that for another day, because it involves making sure that error values are properly checked by all callers.

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori

2009-08-27qdev: add return value to init() callbacks.Gerd Hoffmann
Sorry folks, but it has to be. One more of these invasive qdev patches. We have a serious design bug in the qdev interface: device init callbacks can't signal failure because the init() callback has no return value. This patch fixes it. We have already one case in-tree where this is needed: Try -device virtio-blk-pci (without drive= specified) and watch qemu segfault. This patch fixes it. With usb+scsi being converted to qdev we'll get more devices where the init callback can fail for various reasons.
