2012-02-15qom: Unify type registrationAndreas Färber7-14/+19
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.

2012-02-09AHCI: Masking of IRQs actually masks themAlexander Graf1-0/+2
When masking IRQ lines, we should actually mask them out and not declare them active anymore. Once we mask them in again, they are allowed to trigger again. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2012-02-09AHCI: Fix port reset raceAlexander Graf1-0/+5
bdrv_aio_cancel() can trigger bdrv_aio_flush() which makes all aio that is currently in flight finish. So what we do is: port reset detect ncq in flight cancel ncq delete ncq sg list at which point we have double freed the sg list. Instead, with this patch we do: port reset detect ncq in flight cancel ncq check if we are really still in flight delete ncq sg list which makes things work and gets rid of the race.

2012-02-03qdev: remove baked in notion of aliases (v2)Anthony Liguori1-2/+0
Limit them to the device_add functionality. Device aliases were a hack based on the fact that virtio was modeled the wrong way. The mechanism for aliasing is very limited in that only one alias can exist for any device. We have to support it for the purposes of compatibility but we only need to support it in device_add so restrict it to that piece of code.

2012-02-03qdev: kill off DeviceInfoAnthony Liguori1-1/+1

2012-02-03qdev: register all types natively through QEMU Object ModelAnthony Liguori7-101/+135
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>

These are various small stylistic changes which help make things more consistent such that the automated conversion script can be simpler.

2012-01-21Correct types in bmdma_addr_{read,write}David Gibson1-2/+2
Back when I made patches introducing dma_addr_t and various PCI DMA wrapper functions, I made a mistake. The bmdma_addr_{read,write} functions need to take target_phys_addr_t not dma_addr_t, since they are assigned to MemoryRegionOps callbacks. This patch corrects my error.

2011-12-05block: convert qemu_aio_flush() calls to bdrv_drain_all()Stefan Hajnoczi2-3/+4
Many places in QEMU call qemu_aio_flush() to complete all pending asynchronous I/O. Most of these places actually want to drain all block requests but there is no block layer API to do so. This patch introduces the bdrv_drain_all() API to wait for requests across all BlockDriverStates to complete. As a bonus we perform checks after qemu_aio_wait() to ensure that requests really have finished.

2011-11-18atapi: kill MODE SENSE(6), fix MODE SENSE(10)Paolo Bonzini1-12/+8
Mode page 2A of emulated ATAPI DVD-ROM should have page length 0x14 like SCSI CD-ROM, rather than 0x12. Mode page length is off by 8, as it should contain the length of the payload after the first two bytes. MODE SENSE(6) should be thrown out of ATAPI DVD-ROM emulation. It is not specified in the ATAPI list of MMC-2, and MMC-5 prescribes to use MODE SENSE(10). Anyway, its implementation is wrong.

2011-10-28atapi/scsi-disk: make mode page values coherent between the twoPaolo Bonzini1-7/+7
This patch adds to scsi-disk the missing mode page 0x01 for both disk and CD-ROM drives, and mode page 0x0e for CD drives only. A few offsets were wrong in atapi.c. Also change the 2Ah mode page to expose DVD media read capabilities in the IDE cdrom. This lets you run dvd+rw-mediainfo on the virtual DVD drives.

2011-10-28atapi: cleanup/fix mode sense resultsPaolo Bonzini1-4/+6

2011-10-04RunState: Rename enum values as generated by the QAPILuiz Capitulino1-1/+1
Next commit will convert the query-status command to use the RunState type as generated by the QAPI. In order to "transparently" replace the current enum by the QAPI one, we have to make some changes to some enum values. As the changes are simple renames, I'll do them in one shot. The changes are: - Rename the prefix from RSTATE_ to RUN_STATE_ - RUN_STATE_SAVEVM to RUN_STATE_SAVE_VM - RUN_STATE_IN_MIGRATE to RUN_STATE_INMIGRATE - RUN_STATE_PANICKED to RUN_STATE_INTERNAL_ERROR - RUN_STATE_POST_MIGRATE to RUN_STATE_POSTMIGRATE - RUN_STATE_PRE_LAUNCH to RUN_STATE_PRELAUNCH - RUN_STATE_PRE_MIGRATE to RUN_STATE_PREMIGRATE - RUN_STATE_RESTORE to RUN_STATE_RESTORE_VM - RUN_STATE_PRE_MIGRATE to RUN_STATE_FINISH_MIGRATE Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

2011-09-20AHCI Port Interrupt Enable register cleaning on soft resetAlexander Motin1-3/+5
I've found that FreeBSD AHCI driver doesn't work with AHCI hardware emulation of QEMU 0.15.0. I believe the problem is on QEMU's side. As I see, it clears port's Interrupt Enable register each time when reset of any level happens. Is is reasonable for the global controller reset. It is probably not good, but acceptable for FreeBSD driver for the port hard reset. But it is IMO wrong for the device soft reset. None of real hardware I know behaves that way.

2011-09-15Replace the VMSTOP macros with a proper state typeLuiz Capitulino4-5/+6
Today, when notifying a VM state change with vm_state_notify(), we pass a VMSTOP macro as the 'reason' argument. This is not ideal because the VMSTOP macros tell why qemu stopped and not exactly what the current VM state is. One example to demonstrate this problem is that vm_start() calls vm_state_notify() with reason=0, which turns out to be VMSTOP_USER. This commit fixes that by replacing the VMSTOP macros with a proper state type called RunState. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
