2011-07-17vhost: fix double free on device stopMichael S. Tsirkin1-0/+1
vhost dev stop failed to clear the log field. Typically not an issue as dev start overwrites this field, but if logging gets disabled before the following start, it doesn't so this causes a double free. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
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: 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.

2011-06-23ehci: add freq + maxframes propertiesGerd Hoffmann1-2/+12
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>

2011-06-17PPC: move TLBs to their own arraysAlexander Graf1-2/+2
Until now, we've created a union over multiple different TLB types and allocated that union. While it's a waste of memory (and cache) to allocate TLB information for a TLB type with much information when you only need little, it also inflicts another issue. With the new KVM API, we can now share the TLB between KVM and qemu, but for that to work we need to have both be in the same layout. We can't just stretch it over to fit some internal different TLB representation. Hence this patch moves all TLB types to their own array, allowing us to only address and allocate exactly the boundaries required for the specific TLB type at hand.

2011-06-17PPC: 440: Use 440 style MMU as default, so Qemu knows the MMU typeAlexander Graf1-2/+3
We have some KVM interaction code in Qemu that tries to be clever and ignore some capabilities when running on BookE style MMUs. Unfortunately, the default CPU bamboo was defaulting to was not a BookE-style MMU, resulting in the check to fail. With this patch, guests can run again on 440 with -enable-kvm. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-06-17PPC: E500: Use MAS registers instead of internal TLB representationAlexander Graf1-8/+13
The natural format for e500 cores to do TLB manipulation with are the MAS registers. Instead of converting them into some internal representation and back again when the guest reads them, we can just keep the data identical to the way the guest passed it to us. The main advantage of this approach is that we're getting closer to being able to share MMU data with KVM using shared memory, so that we don't need to copy lots of MMU data back and forth all the time. For this to work however, another patch is required that gets rid of the TLB union, as that destroys our memory layout that needs to be identical with the kernel one.
