2011-06-08ide/core: Remove explicit setting of BM_STATUS_INTKevin Wolf
BM_STATUS_INT is automatically set during ide_set_irq(), there's no reason to set it manually in addition. There is even one case where the interrupt status bit was set, but no IRQ was raised. This is when the PRD table was reached but there is more data to transfer. The correct behaviour for this case is not to set BM_STATUS_INT. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2011-06-07Add an isa device for SGAGlauber Costa
This patch adds a dummy legacy ISA device whose responsibility is to deploy sgabios, an option rom for a serial graphics adapter. The proposal is that this device is always-on when -nographics, but can otherwise be enable in any setup when -device sga is used.

The multiboot info struct's 'boot_device' field has 'part1' set to 0x01, which maps to the second primary partition. To specify the first primary partition, 'part1' should be set to 0x00, since partition numbers start from zero according to the multiboot spec.

2011-06-01virtio-9p: Use relative includes for files in hwStefan Weil
Commit 353ac78d495ef976242abd868f68d78420861c2c moved the files without fixing the include paths. It used a modified CFLAGS to add hw to the include search path, but this breaks builds where the user wants to set special CFLAGS. Long include paths also increase compilation time. Therefore this patch removes the special CFLAGS for virtio and fixes the include statements by using relative include paths. v2: Remove special CFLAGS. v3: Update needed for latest QEMU.

2011-05-27virtio-serial: Clean up virtconsole detectionMarkus Armbruster
virtio-serial-bus needs to treat "virtconsole" devices specially. It uses VirtIOSerialPort member is_console to recognize them. It gets its value via property initialization. Cute hack, except it lets users mess with it: "-device virtconsole,is_console=0" isn't plugged into port 0 as it should. Move the flag to VirtIOSerialPortInfo. Keep the property for backward compatibility; its value has no effect. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Amit Shah <amit.shah@redhat.com>

2011-05-26scsi: Update sense code handlingHannes Reinecke
The SCSI spec has a quite detailed list of sense codes available. It even mandates the use of specific ones for some failure cases. The current implementation just has one type of generic error which is actually a violation of the spec in certain cases. This patch introduces various predefined sense codes to have the sense code reporting more in line with the spec. On top of Hannes's patch I fixed the reply to REQUEST SENSE commands with DESC=0 and a small (<18) length.

2011-05-26scsi: Use 'SCSIRequest' directlyHannes Reinecke
Currently the SCSIRequest structure is abstracted away and cannot accessed directly from the driver. This requires the handler to do a lookup on an abstract 'tag' which identifies the SCSIRequest structure. With this patch the SCSIRequest structure is exposed to the driver. This allows use to use it directly as an argument to the SCSIDeviceInfo callback functions and remove the lookup. A new callback function 'alloc_req' is introduced matching 'free req'; unref'ing to free up resources after use is moved into the scsi_command_complete callbacks. This temporarily introduces a leak of requests that are cancelled, when they are removed from the queue and not from the driver. This is fixed later by introducing scsi_req_cancel. That patch in turn depends on this one, because the argument to scsi_req_cancel is a SCSIRequest.

2011-05-26scsi: reference-count requestsPaolo Bonzini
With the next patch, a device may hold SCSIRequest for an indefinite time. Split a rather big patch, and protect against access errors, by reference counting them. There is some ugliness in scsi_send_command implementation due to the need to unref the request when it fails. This will go away with the next patches, which move the unref'ing to the devices.
