2011-07-17xen_console: fall back to qemu serial deviceAlexander Graf1-4/+7
The new xen_console protocol changed the default xen_console output device from whatever Qemu chose to whatever xenstore choses and "pty" as fallback. This is not how Qemu works. It has its own serial redirection semantics. So it xenstore doesn't contain information on what to do, Qemu is the place to ask. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-07-17xen_console: support the new extended xenstore protocolStefano Stabellini3-6/+23
Since CS 21994 on xen-unstable.hg and CS 466608f3a32e1f9808acdf832a5843af37e5fcec on qemu-xen-unstable.git, few changes have been introduced to the PV console xenstore protocol, as described by the document docs/misc/console.txt under xen-unstable.hg. From the Qemu point of view, very few modifications are needed to correctly support the protocol: read from xenstore the "output" node that tell us what the output of the PV console is going to be. In case the output is a tty, write to xenstore the device name. Changes in v2: - fix error paths: free malloc'ed strings and close the xenstore connection before returning; - remove useless snprintf in xenstore_store_pv_console_info if i == 0. Changes in v3: - replace xs_daemon_open/xs_daemon_close with xs_open/xs_close. Changes in v4: - add a compatibility implementation of xs_open/xs_close. Changes in v5: - fix code style.

2011-07-17xen_disk: treat "aio" as "raw"Stefano Stabellini1-0/+3

2011-07-17xen_disk: cope with missing xenstore "params" nodeStefano Stabellini1-7/+27
When disk is a cdrom and the drive is empty the "params" node in xenstore might be missing completely: cope with it instead of segfaulting. Updated in v2: - actually removed the strchr(blkdev->params, ':') that caused the segfault; - free all the allocated strings from xenstore before returning; Updated in v3: - set blkdev fields to NULL after free'ing them.

2011-07-17xen: add vkbd support for PV on HVM guestsStefano Stabellini1-7/+12
Register the vkbd backend even when running as device emulator for HVM guests: it is useful because it doesn't need a frequent timer like usb. Check whether the XenInput DisplayState has been set in the initialise state, rather than the input state. In case the DisplayState hasn't been set and there is no vfb for this domain, then set the XenInput DisplayState to the default one.

2011-07-12esp: cancel current request only if some request is in flightHervé Poussineau1-1/+1
This bug was introduced in 94d3f98a3f3caddd7875f9a11776daeb84962a7b: scsi_cancel_io was checking if some request was pending before trying to cancel it, while scsi_req_cancel always cancels the request. This may lead to a crash of Qemu due to dereferencing a NULL pointer, as exhibited by NetBSD 5.1 installer on MIPS Magnum emulation.

2011-07-05ide: Initialise buffers with zerosKevin Wolf1-1/+5

2011-07-05ide: Ignore reads during PIO in and writes during PIO outKevin Wolf1-8/+36
This fixes https://bugs.launchpad.net/qemu/+bug/786209: When the DRQ_STAT bit is set, the IDE core permits both data reads and data writes, regardless of whether the current transfer was initiated as a read or write. This potentially leaks uninitialized host memory into the guest, if, before doing anything else to an IDE device, the guest begins a write transaction (e.g. WIN_WRITE), but then *reads* from the IO port instead of writing to it.

2011-06-27virtio-serial: Fix segfault on guest bootLuiz Capitulino1-10/+14
If I start qemu with: # qemu -hda disks/test.img -enable-kvm -m 1G -snapshot \ -device virtio-serial \ -chardev socket,host=localhost,port=1234,server,nowait,id=foo \ -device virtserialport,chardev=foo,name=org.qemu.guest_agent I get a segfault when booting a Fedora 14 guest. The backtrace says: Program terminated with signal 11, Segmentation fault. #0 0x0000000000420850 in handle_control_message (vser=0x3732bd0, buf=0x2c173e0, len=8) at /home/lcapitulino/src/qmp-unstable/hw/virtio-serial-bus.c:335 335 info = DO_UPCAST(VirtIOSerialPortInfo, qdev, port->dev.info); What's happening is VIRTIO_CONSOLE_DEVICE_READY is a message for the whole device, not for an individual port. So port is NULL. This bug was introduced by commit a15bb0d6a981de749452a5180fc8084d625671da. This commit fixes that by making the port returned by find_port_by_id() be used only by the VIRTIO_CONSOLE_PORT_READY and VIRTIO_CONSOLE_PORT_OPEN messages.

This is used to indicate at which speed[s] the device can operate, so that this can be checked to match the ports capabilities when it gets attached to a bus. Note that currently all usb1 emulated device claim to be fullspeed, this seems to not cause any problems, but still seems wrong, because with real hardware keyboards, mice and tablets usually are lo-speed, so reporting these as fullspeed devices seems wrong.

Add properties for the wakeup rate and the max number of frames ehci will process at once. The wakeup rate defaults to 1000 which equals the usb frame rate. This can be reduced to make qemu wake up less often when ehci is active. In case the wakeup rate is reduced or the ehci timer is delayed due to latency issues elsewhere in qemu ehci will process multiple frames at once. The maxframes property specifies the upper limit for this. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
