2009-04-22Change RTC time drift IRQ re-injection (Gleb Natapov)aliguori
Currently IRQ are reinjected as soon as they are acknowledged to the RTC, but Windows sometimes do acknowledgement in a loop with global interrupt disabled waiting for interrupt to be cleared and it does not mask RTC vector in PIC/APIC while doing this. In such situation interrupt injection always fails and RTC interrupt is never cleared. Instead of reinjecting coalesced IRQs on acknowledgement the patch below reinjects them by accelerating RTC clock a bit. This way RTC interrupt is not constantly raced after coalesced interrupt.

2009-04-22implement qemu_blockalign (Stefano Stabellini)aliguori
this patch adds a buffer_alignment field to BlockDriverState and implements a qemu_blockalign function that uses that field to allocate a memory aligned buffer to be used by the block driver. buffer_alignment is initialized to 512 but each block driver can set a different value (at the moment none of them do). This patch modifies ide.c, block-qcow.c, block-qcow2.c and block.c to use qemu_blockalign instead of qemu_memalign. There is only one place left that still uses qemu_memalign to allocate buffers used by block drivers that is posix-aio-compat:handle_aiocb_rw because it is not possible to get the BlockDriverState from that function. However I think it is not important because posix-aio-compat already deals with driver specific code so it is supposed to know its own needs.

2009-04-22xen: add net backend driver. (Gerd Hoffmann)aliguori
This patch adds a network interface backend driver to qemu. It is a pure userspace implemention using the gntdev interface. It uses "qnet" as backend name in xenstore so it doesn't interfere with the netback backend (aka "vnif"). The network backend is hooked into the corrosponding qemu vlan, i.e. vif 0 is hooked into vlan 0. To make the packages actually arrive somewhere you additionally have to link the vlan to the outside world using the usual qemu command line options such as "-net tap,...".
