* 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.

* sparc escc IUS improvements (SunOS 4.1.4 fix)Artyom Tarasenko2010-08-151-26/+30
| | | | | | | | | | | | | | | | According to scc_escc_um.pdf: - Reset Highest IUS must update irq status to allow processing of the next priority interrupt. - rx interrupt has always higher priority than tx on same channel The documentation only explicitly says that Reset Highest IUS command (0x38) clears IUS bits, not that it clears the corresponding interrupt too, so don't clear interrupts on this command. The patch allows SunOS 4.1.4 to use the serial ports Signed-off-by: Artyom Tarasenko <atar4qemu@gmail.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

* New qdev_init_nofail()Markus Armbruster2009-10-071-2/+2
| | | | | | | | | | | | | | | | | | | 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.

* Revert "Get rid of _t suffix"Anthony Liguori2009-10-011-8/+8
| | | | | | | | | | | | 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.

* 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 Hoffmann2009-07-161-35/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Kiszka2009-05-221-2/+2
| | | | | | | | | | | | | | | 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.
