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.

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: NAnthony Liguori <aliguori@us.ibm.com>

Limit the return value (corresponding to the length of the buffer to be DMAed back to the intiator) to the value in req->cmd.xfer, which is the amount of data that the initiator expects. Eliminate now-duplicate code that does this guarding in the functions for individual commands. Without this, the SCRIPTS code in the emulated LSI device eventually raises a DMA interrupt for a data overrun when an INQUIRY command whose buflen exceeds req->cmd.xfer is processed. It's the responsibility of the client to provide a request buffer and allocation length that are large enough for the result of the command.

Replace error_report("DEVICE-NAME: MESSAGE"); by just error_report("MESSAGE"); in block device init functions. DEVICE-NAME is bogus in some cases: it's "scsi-disk" for device scsi-hd and scsi-cd, "virtio-blk-pci" for virtio-blk-s390, and "usb-msd" for usb-storage. There is no real need to put a device name in the message, because error_report() points to the offending command line option already: $ qemu-system-x86_64 --nodefaults --enable-kvm -vnc :0 -S -monitor stdio -usb -device virtio-blk-pci upstream-qemu: -device virtio-blk-pci: virtio-blk-pci: drive property not set upstream-qemu: -device virtio-blk-pci: Device 'virtio-blk-pci' could not be initialized And for a monitor command, it's obvious anyway: $ qemu-system-x86_64 --nodefaults --enable-kvm -vnc :0 -S -monitor stdio -usb (qemu) device_add virtio-blk-pci virtio-blk-pci: drive property not set Device 'virtio-blk-pci' could not be initialized Reported-by: NAmit Shah <amit.shah@redhat.com> Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Signed-off-by: NStefan Hajnoczi <stefanha@linux.vnet.ibm.com>

CD burning messes up the state of the host page cache and host block device. Just pass all operations down to the device, even though that might have slightly worse performance.

scsi-block is a new device that supports device passthrough of Linux block devices (i.e. /dev/sda, not /dev/sg0). It uses SG_IO for commands other than I/O commands, and regular AIO read/writes for I/O commands. Besides being simpler to configure (no mapping required to scsi-generic device names), this removes the need for a large bounce buffer and, in the future, will get scatter/gather support for free from scsi-disk.

The request restart mechanism is generic and could be reused for scsi-generic. In the meanwhile, pushing it to SCSIDevice avoids that scsi_dma_restart_bh looks at SCSIGenericReqs when working on a scsi-block device. The code is the same that is already in hw/scsi-disk.c, with the type flags replaced by req->cmd.mode and a more generic way to requeue SCSI_XFER_NONE commands. I also added a missing call to qemu_del_vm_change_state_handler. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

In some cases a request may be canceled before the completion callback runs. Keep a reference to the request between starting an AIO operation and the corresponding scsi_req_cancel or scsi_*_complete. When a request has to be retried, the request can be dropped because scsi_dma_restart_bh only looks at requests that are enqueued. As such, they always have at least a reference.

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: NLuiz Capitulino <lcapitulino@redhat.com>

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: NLuiz Capitulino <lcapitulino@redhat.com>
