2010-04-03sparc32: improve timer implementationBlue Swirl
Timer with zero period (free-run) will never match. Timer counting starts with tick value of 0x200, not from 0, so the period must calculated from one tick less than the limit. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-01-24Sparc32: fix free-run timerBlue Swirl
According to Sun4M System Architecture Manual chapter 5.3.2, a limit of 0 will not generate interrupts. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori
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 Hoffmann
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 Hoffmann
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.

2009-06-16Remove io_index argument from cpu_register_io_memory()Avi Kivity
The parameter is always zero except when registering the three internal io regions (ROM, unassigned, notdirty). Remove the parameter to reduce the API's power, thus facilitating future change. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-22Introduce reset notifier orderJan Kiszka
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.
