2009-08-27e1000.c doesn't properly emulate EERD and ICS registersBill Paul1-4/+9
Once again, the emulation of the EERD and ICS registers in e1000.c is incorrect. Nobody has noticed this before because none of the Intel-written e1000 drivers use these registers, and all of the independently written open source drivers copy Intel's example, so they don't use them either. Regardless, these registers are documented in the programmer's manuals, and their emulated behavior doesn't match the verified behavior of real hardware, so any software that does use them doesn't function correctly. -Bill Signed-off-by: Bill Paul <wpaul@windriver.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-08-27Fix VM state change handlers running out of orderMarkus Armbruster3-9/+54
When a VM state change handler changes VM state, other VM state change handlers can see the state transitions out of order. bmdma_map(), scsi_disk_init() and virtio_blk_init() install VM state change handlers to restart DMA. These handlers can vm_stop() by running into a write error on a drive with werror=stop. This throws the VM state change handler callback into disarray. Here's an example case I observed: 0. The virtual IDE drive goes south. All future writes return errors. 1. Something encounters a write error, and duly stops the VM with vm_stop(). 2. vm_stop() calls vm_state_notify(0). 3. vm_state_notify() runs the callbacks in list vm_change_state_head. It contains ide_dma_restart_cb() installed by bmdma_map(). It also contains audio_vm_change_state_handler() installed by audio_init(). 4. audio_vm_change_state_handler() stops audio stuff. 5. User continues VM with monitor command "c". This runs vm_start(). 6. vm_start() calls vm_state_notify(1). 7. vm_state_notify() runs the callbacks in vm_change_state_head. 8. ide_dma_restart_cb() happens to come first. It does its work, runs into a write error, and duly stops the VM with vm_stop(). 9. vm_stop() runs vm_state_notify(0). 10. vm_state_notify() runs the callbacks in vm_change_state_head. 11. audio_vm_change_state_handler() stops audio stuff. Which isn't running. 12. vm_stop() finishes, ide_dma_restart_cb() finishes, step 7's vm_state_notify() resumes running handlers. 13. audio_vm_change_state_handler() starts audio stuff. Oopsie. Fix this by moving the actual write from each VM state change handler into a new bottom half (suggested by Gleb Natapov).

2009-08-27Remove the virtio-{blk, console}-pci-0-10 device typesMark McLoughlin1-46/+11

2009-07-29Add a pc-0.11 machine type and make the pc type an aliasMark McLoughlin1-1/+2
The pc-0.11 type allows users of qemu-0.11 to use a machine type which they know will remain compatible when the upgrade to qemu-0.12. Management tools may choose to canonicalize the 'pc' machine type to 'pc-0.11' so that if the 'pc' alias changes target in future versions of qemu, the machine type used will remain compatible.

2009-07-29Add machine type aliasesMark McLoughlin1-0/+1
Add an 'alias' field to QEMUMachine and display it in the output of 'qemu -M ?' with an '(aliased to foo)' suffix. Aliases can change targets in newer versions of qemu, so management tools may choose canonicalize machine types to ensure that if a user chooses an alias, that the actual machine type used will remain compatible in future. This is intended to mimic a symlink to a machine description file. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-07-29HPET fixes for reg writesBeth Kon2-13/+8
This patch addresses the problems found by Andriy Gapon: - The code was incorrectly overwriting the high order 32 bits of the timer and hpet config registers. This didn't show up in testing because linux and windows use hpet in legacy mode, where the high order 32 bits (advertising available interrupts) of the timer config register are ignored, and the high order 32 bits of the hpet config register are reserved and unused. - The mask for level-triggered interrupts was off by a bit. (hpet doesn't currently support level-triggered interrupts). In addition, I removed some unused #defines, and corrected the ioapic interrupt values advertised. I'd set this up early in hpet development and never went back to correct it, and no bugs resulted since linux and windows use hpet in legacy mode where available interrupts are ignored.

2009-07-16qdev: rework device properties.Gerd Hoffmann45-390/+920
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.
