2009-10-05floppy: move dma setup + drive connect to fdctrl_init_common()Gerd Hoffmann
isa-fdc is completely qdev-ified with this patch applied, all configuration uses properties. sysbus-fdc needs dma_channel config fixed. There is only one user (mips_jazz) which uses dma channel 0. Can anyone knowing this platform suggest how to deal with it? Is hardcoding fine? Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.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.

2009-09-10qdev: simplify isa irq assignmentsGerd Hoffmann
isa-bus owns the isa irqs now, so it can hand them out directly. There is no need for the separate isa_connect_irqs step, drop it. Also hard-code isa interrupts which can't be configured anyway. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2009-09-10qdev: drop iobase properties from isa busGerd Hoffmann
Lot of ISA devices work at fixed addresses, so having iobase as bus property doesn't make much sense. Devices which can have different iobases will get a device property. Also simply hard-code stuff which can't be configured anyway. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
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.

2009-08-27isa bus irq changes and fixes.Gerd Hoffmann
Changes: (1) make isa-bus maintain isa irqs, complain when allocating already taken irqs. (2) note that (1) works only for isa devices converted to qdev already (floppy and ps2/kbd/mouse right now), so more work is needed to make this really useful. (3) split floppy init into isa and sysbus versions. (4) add sysbus->isa bridge & fix -M isapc breakage.

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.

2009-05-22Introduce 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.

2009-01-24Floppy: Properly handle Sense Interrupt Status after FDC Resetblueswir1
Original text below. Attached is a patch that changes how the emulated floppy controller replies to Sense Interrupt Status commands immediately after a controller reset. The specs state that after a Reset the 82078 goes into polling mode which needs four Sense Interrupt Status commands to be issued afterwards to clear the status of each drive. Currently we always respond to Sense Interrupt Status with a SEEK END instead of POLLING. This causes a problem with the SCO Openserver installer which is expects a POLLING state after reset. This patch returns a POLLING status for four Sense Interrupt Status requests immediately after a controller reset. This approach mirrors the way Bochs handles this situation. With the attached patch applied Openserver gets further when trying to load storage drivers from the floppy disk (blocked by another issue, patch on its way). I have successfully tested the floppy drive on the following OSs after applying this patch: Windows 98, Windows XP SP2, Linux x86 (SysRescCD 1.1.3 and Ubuntu 8.10).

2008-05-01FDC: Fix data transfer len (Hervé Poussineau)blueswir1
