2012-06-21xilinx_timer: Fixed deadlock issuePeter A. G. Crosthwaite1-1/+1
The timer was deadlocking when the interval was set too low. It would cause a flood of timer events and the CPU would halt indefinately. This is a known issue and theres a generic workaround in place in ptimer on ptimer_set_limit(), however the Xilinx timer uses ptimer_set_count() instead of set_limit. Changed the call to set_count() to an equivalent call of set_limit() instead, which brings the workaround into play. Signed-off-by: Peter A. G.

2012-06-21xilinx_timer: Removed include of qemu-timerPeter A. G. Crosthwaite1-1/+0
The Xilinx timer does not interact with the qemu_timer API, so dont include it. Signed-off-by: Peter A. G. Crosthwaite <peter.crosthwaite@petalogix.com> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
2012-06-15xilinx_timer: changed device namePeter A. G. Crosthwaite1-2/+2
Changed device name to xlnx,xps-timer. This is the exact name of the device in the xilinx EDK development tools. Signed-off-by: Peter A. G. Crosthwaite <peter.crosthwaite@petalogix.com> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
2012-06-15xilinx_timer: changed nr_timers to one_timer_onlyPeter A. G. Crosthwaite1-6/+11
The configurable property for this IP in the Xilinx tools is a boolean switch "one-timer-only" that flicks this timer from being dual channel to single. Updated QEMU to work the same way for better match with the IP core and its TRM. Signed-off-by: Peter A. G. Crosthwaite <peter.crosthwaite@petalogix.com> Signed-off-by: Edgar E.

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

2012-02-03qdev: register all types natively through QEMU Object ModelAnthony Liguori1-6/+8
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>
2012-01-27sysbus: apic: ioapic: convert to QEMU Object ModelAnthony Liguori1-9/+18
This converts three devices because apic and ioapic are subclasses of sysbus. Converting subclasses independently of their base class is prohibitively hard. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

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.

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.

2009-08-27qdev: 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 Hoffmann1-7/+25
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.
