2011-08-16scsi: do not overwrite memory on REQUEST SENSE commands with a large bufferPaolo Bonzini
Other scsi_target_reqops commands were careful about not using r->cmd.xfer directly, and instead always cap it to a fixed length. This was not done for REQUEST SENSE, and this patch fixes it.

Don't use req before it has been initialised in scsi_req_new(). This fixes a compile failure due to gcc complaining about this. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-08-12scsi: add support for unit attention conditionsPaolo Bonzini
Unit attention conditions override any sense data the device already has. Their signaling and clearing is handled entirely by the SCSIBus code, and they are completely transparent to the SCSIDevices.

2011-08-12scsi: move request parsing to common codePaolo Bonzini

2011-08-12scsi: push lun field to SCSIDevicePaolo Bonzini
This will let SCSIBus detect requests sent to an invalid LUN, and handle them itself. However, there will be still support for only one LUN per target Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-08-12scsi: introduce SCSICommandPaolo Bonzini
This struct is currently unnamed. Give it a name and use it explicitly to decouple (some parts of) CDB parsing from SCSIRequest. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-08-12scsi: pass cdb already to scsi_req_newPaolo Bonzini
Right now the CDB is not passed to the SCSIBus until scsi_req_enqueue. Passing it to scsi_req_new will let scsi_req_new dispatch common requests through different reqops. Moving the memcpy to scsi_req_new is a hack that will go away as soon as scsi_req_new will also take care of the parsing.

2011-08-12scsi: introduce SCSIReqOpsPaolo Bonzini
This will let allow requests to be dispatched through different callbacks, either common or per-device. This patch adjusts the API, the next one will move members to SCSIReqOps. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-08-12scsi: move sense handling to generic codePaolo Bonzini
With this patch, sense data is stored in the generic data structures for SCSI devices and requests. The SCSI layer takes care of storing sense data in the SCSIDevice for the subsequent REQUEST SENSE command. At the same time, get_sense is removed and scsi_req_get_sense can use an entirely generic implementation.

2011-08-12scsi: pass status when completingPaolo Bonzini
A small improvement in the SCSI request API. Pass the status at the time the request is completed, so that we can assert that no request is completed twice. This would have detected the problem fixed in the previous patch.

2011-08-12vscsi: always use get_sensePaolo Bonzini
vscsi supports autosensing by providing sense data directly in the response. When get_sense was added, the older state machine approach that sent REQUEST SENSE commands separately was left in place. Remove it, all existing SCSIDevices do support autosensing and the next patches will make the support come for free from the SCSIBus.

2011-08-12scsi-disk: no need to call scsi_req_data on a short readPaolo Bonzini
In fact, if the HBA's transfer_data callback goes on with scsi_req_continue the request will be completed successfully instead of showing a failure. It can even cause a segmentation fault. An easy way to trigger it is "eject -f cd" during installation (during media test if the installer does something like that).

2011-08-12pc: make vgabios exit port more usefulAnthony Liguori
We've always listened on port 501 for vgabios panic messages. In the entire time I've worked on QEMU, I've never actually seen a vgabios panic message :-) If we change the semantics of this port a little bit, it makes it possible to use it for more interesting use-cases. I chose this approach instead of adding a new I/O port because it avoids having a guest visible change. This change allows single-byte access to port 501 and also uses the value written to construct an exit code. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Break is only noticable with newer spice-server library (0.8.2 release or 0.9.0 and newer on master branch). ioport_write's val was changed from uint32_t to uint64_t, this broke two printfs.

2011-08-10usb/hid: add hid_pointer_activate, use itGerd Hoffmann
HID reorganziation broke the usb tablet in windows xp. The reason is that xp activates idle before it starts polling, which creates a chicken-and-egg issue: We don't call hid_pointer_poll because there are no pending events. We don't get any events because the activation code in hid_pointer_poll is never executed and thus all pointer events are routed to the PS/2 mouse by qemu. Fix this by creating a hid_pointer_activate function and call it from usb-hid when the guest sets the idle state. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
