2011-05-08xen: Support new libxc calls from xen unstable.Anthony PERARD
This patch updates the libxenctrl calls in Qemu to use the new interface, otherwise Qemu wouldn't be able to build against new versions of the library. We check libxenctrl version in configure, from Xen 3.3.0 to Xen unstable.

2011-05-05eepro100: Fix endianness issuesStefan Weil
Like other Intel devices, e100 (eepro100) uses little endian byte order. This patch was tested with these combinations: i386 host, i386 + mipsel guests (le-le) mipsel host, i386 guest (le-le) i386 host, mips + ppc guests (le-be) mips host, i386 guest (be-le) mips and mipsel hosts were emulated machines. v2: Use prefix for new functions. Add the same prefix to stl_le_phys. Fix alignment of mem (needed for word/dword reads/writes). Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2011-05-05eepro100: Pad received short framesStefan Weil
QEMU sends frames smaller than 60 bytes to ethernet nics. Such frames are rejected by real NICs and their emulations. To avoid this behaviour, other NIC emulations pad received frames. This patch enables this workaround for eepro100, too. All related code is marked with CONFIG_PAD_RECEIVED_FRAMES, so we can drop this in case QEMU's networking code is ever changed.

2011-05-05eepro100: Avoid duplicate debug messagesStefan Weil
When DEBUG_EEPRO100 was enabled, unsupported writes were logged twice. Now logging in eepro100_write1 and eepro100_write2 is similar to the logging in eepro100_write4 (which already was correct). Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2011-05-04usb: mass storage fixGerd Hoffmann

2011-05-04usb: control buffer fixesHans de Goede
Windows allows control transfers to pass up to 4k of data, so raise our control buffer size to 4k. For control out transfers the usb core code copies the control request data to a buffer before calling the device's handle_control callback. Add a check for overflowing the buffer before copying the data. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2011-05-03spice: drop obsolete iothread lockingGerd Hoffmann
We don't use qemu internals from spice server context any more. Thus we don't also need to grab the iothread mutex from spice server context. And we don't have to temporarely release the lock to avoid deadlocks. Drop all the calls. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-05-03spice: don't call displaystate callbacks from spice server context.Gerd Hoffmann
This patch moves the displaystate callback calls for setting the cursor and the mouse pointer from spice server to qemu (iothread) context. This allows us to simplify locking. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-05-03spice: don't create updates in spice server context.Gerd Hoffmann
This patch moves the creation of spice screen updates from the spice server context to qemu iothread context (display refresh timer to be exact). This way we avoid accessing qemu internals (display surface) from spice thread context which in turn allows us to simplify locking. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2011-04-28virtio-serial: Fix endianness bug in the config spaceAlexey Kardashevskiy
The virtio serial specification requres that the values in the config space are encoded in native endian of the guest. The qemu virtio-serial code did not do conversion to the guest endian format what caused problems when host and guest use different format. This patch corrects the qemu side, correctly doing host-native <-> guest-native conversions when accessing the config space. This won't break any setups that aren't already broken, and fixes the case of different host and guest endianness.

2011-04-27ioapic: Do not set irr for masked edge IRQsJan Kiszka
So far we set IRR for edge IRQs even if the pin is masked. If the guest later on unmasks and switches the pin to level-triggered mode, irr will remain set, causing an IRQ storm. The point is that setting IRR is not correct in this case according to the spec, and avoiding this resolves the issue.
