2010-06-10esp: lower IRQ on soft resetBlue Swirl1-5/+14
42f1ced228c9b616cfa2b69846025271618e4ef5 removed irq lowering during reset. However, for chip reset command and DMA reset signal, its actually the correct thing to do. Lower IRQ on soft reset only. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-10-07New qdev_init_nofail()Markus Armbruster1-1/+1
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 Liguori1-3/+3
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. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

2009-09-09qdev/scsi: add scsi bus support to qdev, convert drivers.Gerd Hoffmann1-40/+14
* Add SCSIBus. * Add SCSIDeviceInfo, move device callbacks here. * add qdev/scsi helper functions. * convert drivers. Adding scsi disks via -device works now, i.e. you can do: -drive id=sda,if=none,... -device lsi -device scsi-disk,drive=sda legacy command lines (-drive if=scsi,...) continue to work.

2009-09-05esp: handle "select without attention"Artyom Tarasenko1-5/+23
Up to now "select without attention" was handled the same way as "select with attention". According to http://www.ibiblio.org/pub/historic-linux/early-ports/Sparc/NCR/NCR53C9X.txt select without ATN sends the CDB (Command Descriptor Block) directly, whereas select with ATN sends one message phase byte followed by 6, 10, or 12 command phase bytes. The attached patch implements the behaviour described above.

2009-08-27qdev: add return value to init() callbacks.Gerd Hoffmann1-1/+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.

2009-07-16qdev: rework device properties.Gerd Hoffmann1-8/+6
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.

2009-05-22Introduce reset notifier orderJan Kiszka1-1/+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.
