2011-01-24usb-msd: Propagate removable bit to SCSI deviceStefan Hajnoczi1-1/+3
USB Mass Storage Devices sometimes have the RMB (removable) bit set in the SCSI INQUIRY response. Thumbdrives tend to have the bit set whereas hard disks do not. Operating systems differentiate between removable devices and fixed devices. Under Linux, the anaconda installer looks for removable devices. Under Windows, only fixed devices may have more than one partition and AutoRun is also affected by the removable bit. For these reasons, allow USB Mass Storage Devices to override the removable bit: qemu -usb -drive if=none,file=test.img,cache=none,id=disk0 -device usb-storage,drive=disk0,removable=on The default is off.

2011-01-24scsi: Allow scsi_bus_legacy_add_drive() to set removable bitStefan Hajnoczi4-5/+10
scsi-disk devices may wish to override the removable bit. Add support for a qdev property on SCSI devices. This is will be used by usb-msd. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2011-01-24scsi-disk: Allow overriding SCSI INQUIRY removable bitStefan Hajnoczi1-0/+3
Provide the "removable" qdev property bit to override the SCSI INQUIRY removable (RMB) bit for non-CDROM devices. This will be used by USB Mass Storage Devices, which sometimes have this guest-visible bit set and sometimes do not. They therefore requires a means for user configuration.

2011-01-24usb core: add migration supportGerd Hoffmann3-5/+31
Yes, seriously. There is no migration support at all for usb devices. They loose state, especially the device address, and stop responding because of that. Oops. Luckily there is so much broken usb hardware out there that the guest usually just kicks the device hard (via port reset and reinitialization), then continues without a hitch. So we got away with that in a surprising high number of cases. The arrival of remote wakeup (which enables autosuspend support) changes that picture though. The usb devices also forget that it they are supposed to wakeup, so they don't do that. The host also doesn't notice the device stopped working in case it suspended the device and thus expects it waking up instead of polling it. Result is that your mouse is dead. Lets start fixing that. Add a vmstate struct for USBDevice. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-24usb hid: move head+n to common structGerd Hoffmann1-24/+22
This patch moves the 'head' and 'n' fields from USBMouseState and USBKeyboardState to the common USBHIDState struct. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-24usb keyboard: add event event queueGerd Hoffmann1-6/+32
This patch adds a event queue to the usb keyboard. This makes sure the guest will see all key events even if they come in bursts. With this patch applied sending Ctrl-Alt-Del using vncviewer's F8 menu works. Also with autosuspend enabled the first keypress on a suspended keyboard takes a little longer to be delivered to the guest because the usb bus must be resumed first. Without event queue this easily gets lost. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-24add event queueing to USB HIDPaolo Bonzini1-94/+127
The polling nature of the USB HID device makes it very hard to double click or drag while on a high-latency VNC connection. This patch, based on work done in the Xen qemu-dm tree by Ian Jackson, fixes this bug by adding an event queue to the device. The event queue associates each movement with the correct button state, and remembers all button presses and releases as well.

Live migration from and to spice 0.4 qxl devices isn't going to work. Rip out the bits which attempt to support that. Zap the subsection logic which is obsolete now. Bumb the version to make a clean cut. This should obviously go in before 0.14 is released. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2011-01-24ide: kill ide_dma_submit_checkChristoph Hellwig1-9/+6
Merge ide_dma_submit_check into it's only caller. Also use tail recursion using a goto instead of a real recursion - this avoid overflowing the stack in the pathological situation of an recurring error that is ignored. We'll still be busy looping in ide_dma_cb, but at least won't eat up all stack space after this. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2011-01-24ide: also reset io_buffer_index for writesChristoph Hellwig1-2/+1
Currenly the code only resets the io_buffer_index field for reads, but the code seems to expect this for all types of I/O.

2011-01-21sm501: fix screen redrawAurelien Jarno1-3/+4
Due to signed/unsigned comparison, the dirty bits are never reset, and the screen redrawn each time. Fix that by only using ram_addr_t types, and looking for page_min != addr_max instead. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-20gt64xxx: set isa_mem_base during registrationAurelien Jarno1-0/+5

deassert intx on device reset. So far pci_device_reset() is used for system reset. In that case, interrupt controller is reset at the same time so that all irq is are deasserted.
