2011-01-20gt64xxx: set isa_mem_base during registrationAurelien Jarno1-0/+5
isa_mem_base is computed from registers during reset, but due to QEMU limitations some devices (e.g. VGA card) need to know it earlier when they are registered. Workaround this by setting the value during registration instead of reset. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-20hw/pl190.c: Fix writing of default vector addressPeter Maydell1-3/+1
The PL190 implementation keeps the default vector address in vect_addr[16], but we weren't using this for writes to the DEFVECTADDR register. As a result of this fix the default_addr structure member is unused and we can delete it.

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. But now pci bus reset/flr is supported, and in that case irq needs to be disabled explicitly. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

When reading cp0_count from a timer with a late trigger that should already have expired, expire it and raise the timer irq.

2011-01-16USB keyboard emulation key mapping errorMichael Tokarev1-1/+1
The USB keyboard emulation's translation table in hw/usb-hid.c doesn't match the codes actually sent for the Logo (a.k.a. "Windows") or Menu keys. This results in the guest OS not being able to receive these keys at all when the USB keyboard emulation is being used. In particular, both the keymap in /usr/share/kvm/keymaps/modifiers and the evdev table in x_keymap.c map these keys to 0xdb, 0xdc, and 0xdd, while usb_hid_usage_keys[] seems to be expecting them to be mapped to 0x7d, 0x7e, and 0x7f. The attached patch seems to fix the problem, at least in my (limited) testing. http://bugs.debian.org/578846 http://bugs.debian.org/600593 (cloned from the above against different pkg) https://bugs.launchpad.net/qemu/+bug/584139 Signed-Off-By: Brad Jorsch <anomie@users.sourceforge.net> Signed-Off-By: Michael Tokarev <mjt@tls.msk.ru> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

The current default of 16 buffers for the control vq is too small. We can get more entries in there, for example when asking the guest to add max. allowed ports.

2011-01-10virtio-pci: Use ioeventfd for virtqueue notifyStefan Hajnoczi3-25/+184
Virtqueue notify is currently handled synchronously in userspace virtio. This prevents the vcpu from executing guest code while hardware emulation code handles the notify. On systems that support KVM, the ioeventfd mechanism can be used to make virtqueue notify a lightweight exit by deferring hardware emulation to the iothread and allowing the VM to continue execution. This model is similar to how vhost receives virtqueue notifies. The result of this change is improved performance for userspace virtio devices. Virtio-blk throughput increases especially for multithreaded scenarios and virtio-net transmit throughput increases substantially. Some virtio devices are known to have guest drivers which expect a notify to be processed synchronously and spin waiting for completion. For virtio-net, this also seems to interact with the guest stack in strange ways so that TCP throughput for small message sizes (~200bytes) is harmed. Only enable ioeventfd for virtio-blk for now. Care must be taken not to interfere with vhost-net, which uses host notifiers. If the set_host_notifier() API is used by a device virtio-pci will disable virtio-ioeventfd and let the device deal with host notifiers as it wishes. Finally, there used to be a limit of 6 KVM io bus devices inside the kernel. On such a kernel, don't use ioeventfd for virtqueue host notification since the limit is reached too easily. This ensures that existing vhost-net setups (which always use ioeventfd) have ioeventfds available so they can continue to work. After migration and on VM change state (running/paused) virtio-ioeventfd will enable/disable itself. * VIRTIO_CONFIG_S_DRIVER_OK -> enable virtio-ioeventfd * !VIRTIO_CONFIG_S_DRIVER_OK -> disable virtio-ioeventfd * virtio_pci_set_host_notifier() -> disable virtio-ioeventfd * vm_change_state(running=0) -> disable virtio-ioeventfd * vm_change_state(running=1) -> enable virtio-ioeventfd Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Michael S.
