2012-06-18qbus: Make child devices linksAnthony Liguori1-6/+9
Make qbus children show up as link<> properties. There is no stable addressing for qbus children so we use an unstable naming convention. This is okay in QOM though because the composition name is expected to be what's stable.

2012-06-18qdev: Convert busses to QEMU Object ModelAnthony Liguori1-5/+7
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.

2012-06-18qdev: Move bus properties to abstract superclassesPaolo Bonzini1-1/+1
In qdev, each bus in practice identified an abstract superclass, but this was mostly hidden. In QOM, instead, these abstract classes are explicit so we can move bus properties there. All bus property walks are removed, and all device property walks are changed to look along the class hierarchy instead. We would have duplicates if class A defines some properties and its subclass B does not define any, because class_b->props will be left equal to class_a->props. The solution here is to reintroduce the class_base_init TypeInfo callback, that was present in one of the early QOM versions but removed (on my request...) before committing. This breaks global bus properties, an obscure feature when used with the command-line which is actually useful and used when used by backwards-compatible machine types. So this patch also adjusts the global bus properties in hw/pc_piix.c to refer to the abstract class. Globals and other properties must be modified in the same patch to avoid complications related to initialization ordering.

2012-06-07msi: Invoke msi/msix_write_config from PCI coreJan Kiszka1-12/+0
Also this functions is better invoked by the core than by each and every device. This allows to drop the config_write callbacks from ich and intel-hda.

2012-06-07msi: Invoke msi/msix_reset from PCI coreJan Kiszka1-3/+0
There is no point in pushing this burden to the devices, they tend to forget to call them (like intel-hda, ahci, xhci did). Instead, reset functions are now called from pci_device_reset. They do nothing if MSI/MSI-X is not in use.

2012-02-15qom: Unify type registrationAndreas Färber1-2/+3
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.

2012-02-03qdev: kill off DeviceInfoAnthony Liguori1-1/+1
It is no longer used in the tree since everything is done natively through QEMU Object Model. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-03qdev: register all types natively through QEMU Object ModelAnthony Liguori1-17/+20
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>

2011-10-28qdev: switch children device list to QTAILQPaolo Bonzini1-3/+3
SCSI buses will need to read the children list first-to-last.

2011-03-21change all other clock references to use nanosecond resolution accessorsPaolo Bonzini1-1/+1
This was done with: sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \ $(git grep -l 'qemu_get_clock\>' ) sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \ $(git grep -l 'qemu_new_timer\>' ) after checking that get_clock and new_timer never occur twice on the same line. There were no missed occurrences; however, even if there had been, they would have been caught by the compiler. There was exactly one false positive in qemu_run_timers: - current_time = qemu_get_clock (clock); + current_time = qemu_get_clock_ns (clock); which is of course not in this patch.

2010-12-11Add endianness as io mem parameterAlexander Graf1-1/+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.

2010-11-01Add Intel HD Audio support to qemu.Gerd Hoffmann1-0/+1250
This patch adds three devices to qemu: intel-hda Intel HD Audio Controller, the PCI device. Provides a HDA bus. Emulates ICH6 at the moment. Adding a ICH9 PCIE variant shouldn't be hard. hda-duplex HDA Codec. Attaches to the HDA bus. Supports 16bit stereo, rates 16k -> 96k, playback, recording and volume control (with CONFIG_MIXEMU=y). hda-output HDA Codec without recording support. Subset of the hda-duplex codec. Use this if you don't want your guests access your mic. Usage: add '-device intel-hda -device hda-duplex' to your command line. Tested guests: * Linux works. * Win7 works. * DOS (mpxplay) works. * WinXP doesn't work. [ v2 changes ] * Fixed endianess, big endian hosts work now. * Fixed some emulation bugs. * Added immediate command emulation. * Added vmstate support. * Make it behave like all other sound card drivers: - can be configured via '--audio-card-list=hda' - can be added to a VM using '-soundhw hda' * Code style fixups. * Zapped guest-triggerable asserts. * Handle partial reads/writes of audio data correctly.
