* Make all static TypeInfos constAndreas Färber2013-01-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

* Rename target_phys_addr_t to hwaddrAvi Kivity2012-10-231-4/+4
| | | | | | | | | | | | | | | 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). Replace it with a finger-friendly, standards conformant hwaddr. Outstanding patchsets can be fixed up with the command git rebase -i --exec 'find -name "*.[ch]" | xargs s/target_phys_addr_t/hwaddr/g' origin Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
* qom: Unify type registrationAndreas Färber2012-02-151-2/+2
| | | | | | | | | | | | | Replace device_init() with generalized type_init(). While at it, unify naming convention: type_init([$prefix_]register_types) Also, type_init() is a function, so add preceding blank line where necessary and don't put a semicolon after the closing brace.

* qdev: register all types natively through QEMU Object ModelAnthony Liguori2012-02-031-8/+10
| | | | | | | | | | | | | | | | | | | | | 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>
* sysbus: apic: ioapic: convert to QEMU Object ModelAnthony Liguori2012-01-271-11/+20

* sparc32: ledma extra registersBob Breuer2010-12-181-1/+14
| | | | | | | | | | ledma has 0x20 bytes of registers according to OBP, and at least Solaris9 reads the 5th register which is beyond what we've mapped. So let's setup a flag (inspired by a previous patch from Blue Swirl) to identify ledma from espdma, and map another 16 bytes of registers which return 0.

* Add endianness as io mem parameterAlexander Graf2010-12-111-1/+2
| | | | | | | | | | | | | 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.

* ESP: fix ESP DMA access when DMA is not enabledBlue Swirl2010-09-111-4/+19
| | | | | | | | | | | | | | Sending ESP a command caused it to trigger DMA immediately even if DMA was not enabled at the DMA controller. Add a signal from DMA controller to ESP to tell ESP about changes in DMA enable bit. Also use the correct function for setting up GPIO outputs. This fixes NetBSD 1.6.1 through 3.0 boot.

| | | | | | | | | | | | In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem.

* qdev: add return value to init() callbacks.Gerd Hoffmann2009-08-271-1/+2
| | | | | | | | | | | | | | | | | | 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.

* qdev: rework device properties.Gerd Hoffmann2009-07-161-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is a major overhaul of the device properties. The properties are saved directly in the device state struct now, the linked list of property values is gone. Advantages: * We don't have to maintain the list with the property values. * The value in the property list and the value actually used by the device can't go out of sync any more (used to happen for the pci.devfn == -1 case) because there is only one place where the value is stored. * A record describing the property is required now, you can't set random properties any more. There are bus-specific and device-specific properties. The former should be used for properties common to all bus drivers. Typical use case is bus addressing, i.e. pci.devfn and i2c.address. Properties have a PropertyInfo struct attached with name, size and function pointers to parse and print properties. A few common property types have PropertyInfos defined in qdev-properties.c. Drivers are free to implement their own very special property parsers if needed. Properties can have default values. If unset they are zero-filled.

* Introduce reset notifier orderJan Kiszka2009-05-221-1/+1
| | | | | | | | | | | | | | | Add the parameter 'order' to qemu_register_reset and sort callbacks on registration. On system reset, callbacks with lower order will be invoked before those with higher order. Update all existing users to the standard order 0. Note: At least for x86, the existing users seem to assume that handlers are called in their registration order. Therefore, the patch preserves this property. If someone feels bored, (s)he could try to identify this dependency and express it properly on callback registration.
