2013-04-08hw: move headers to include/Paolo Bonzini
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.

2013-04-01sysbus: Remove sysbus_add_memory and sysbus_del_memoryPeter Maydell
Remove the sysbus_add_memory and sysbus_del_memory functions. These are trivial wrappers for mapping a memory region into the system memory space, and have no users now. Sysbus devices should never map their own memory regions anyway; the correct API for mapping an mmio region is for the creator of the device to use sysbus_mmio_map.

2013-03-01hw: include hw header files with full pathsPaolo Bonzini
Done with this script: cd hw for i in `find . -name '*.h' | sed 's/^..//'`; do echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,' done | sed -i -f - `find . -type f` This is so that paths remain valid as files are moved. Instead, files in hw/dataplane are referenced with the relative path. We know they are not going to move to include/, and they are the only include files that are in subdirectories _and_ move.

2013-02-27Fix guest OS hang when 64bit PCI bar presentAlexey Korolev
This patch addresses the issue fully described here: http://lists.nongnu.org/archive/html/qemu-devel/2013-02/msg01804.html Linux kernels prior to 2.6.36 do not disable the PCI device during enumeration process. Since lower and higher parts of a 64bit BAR are programmed separately this leads to qemu receiving a request to occupy a completely wrong address region for a short period of time. We have found that the boot process screws up completely if kvm-apic range is overlapped even for a short period of time (it is fine for other regions though). This patch raises the priority of the kvm-apic memory region, so it is never pushed out by PCI devices. The patch is quite safe as it does not touch memory manager.

2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific).

2012-06-18qdev: Convert busses to QEMU Object ModelAnthony Liguori
This is far less interesting than it sounds. We simply add an Object to each BusState and then register the types appropriately. Most of the interesting refactoring will follow in the next patches. Since we're changing fundamental type names (BusInfo -> BusClass), it all needs to convert at once. Fortunately, not a lot of code is affected.

2012-02-03qdev: register all types natively through QEMU Object ModelAnthony Liguori
This was done in a mostly automated fashion. I did it in three steps and then rebased it into a single step which avoids repeatedly touching every file in the tree. The first step was a sed-based addition of the parent type to the subclass registration functions. The second step was another sed-based removal of subclass registration functions while also adding virtual functions from the base class into a class_init function as appropriate. Finally, a python script was used to convert the DeviceInfo structures and qdev_register_subclass functions to TypeInfo structures, class_init functions, and type_register_static calls. We are almost fully converted to QOM after this commit. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-08-28hw/sysbus: Add sysbus_mmio_get_region()Peter Maydell
Add a sysbus_mmio_get_region() which allows users of sysbus devices to turn a (SysBusDevice*, mmioidx) tuple into a MemoryRegion*. This enables some useful simplifications of devices which pass through another device's mmio region (either directly or by implementing some kind of memory controller device).

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.
