2013-01-02dataplane: add event loopStefan Hajnoczi
Outside the safety of the global mutex we need to poll on file descriptors. I found epoll(2) is a convenient way to do that, although other options could replace this module in the future (such as an AioContext-based loop or glib's GMainLoop). One important feature of this small event loop implementation is that the loop can be terminated in a thread-safe way. This allows QEMU to stop the data plane thread cleanly.

2013-01-02dataplane: add virtqueue vring codeStefan Hajnoczi
The virtio-blk-data-plane cannot access memory using the usual QEMU functions since it executes outside the global mutex and the memory APIs are this time are not thread-safe. This patch introduces a virtqueue module based on the kernel's vhost vring code. The trick is that we map guest memory ahead of time and access it cheaply outside the global mutex. Once the hardware emulation code can execute outside the global mutex it will be possible to drop this code. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-01-02dataplane: add host memory mapping codeStefan Hajnoczi
The data plane thread needs to map guest physical addresses to host pointers. Normally this is done with cpu_physical_memory_map() but the function assumes the global mutex is held. The data plane thread does not touch the global mutex and therefore needs a thread-safe memory mapping mechanism. Hostmem registers a MemoryListener similar to how vhost collects and pushes memory region information into the kernel. There is a fine-grained lock on the regions list which is held during lookup and when installing a new regions list. When the physical memory map changes the MemoryListener callbacks are invoked. They build up a new list of memory regions which is finally installed when the list has been completed. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2013-01-01pflash_cfi01: Suppress warning when Linux probes for AMD flashStefan Weil
There are several ARM and MIPS boards which are manufactured with either Intel (pflash_cfi01.c) or AMD (pflash_cfi02.c) flash memory. The Linux kernel supports both and first probes for AMD flash which resulted in one or two warnings from the Intel flash emulation: pflash_write: Unimplemented flash cmd sequence (offset 0000000000000000, wcycle 0x0 cmd 0x0 value 0xf000f0) pflash_write: Unimplemented flash cmd sequence (offset 0000000000000000, wcycle 0x0 cmd 0x0 value 0xf0) These warnings confuse users, so suppress them.

2012-12-26virtio-pci: don't poll masked vectorsMichael S. Tsirkin
At the moment, when irqfd is in use but a vector is masked, qemu will poll it and handle vector masks in userspace. Since almost no one ever looks at the pending bits, it is better to defer this until pending bits are actually read. Implement this optimization using the new poll notifier. Signed-off-by: Michael S.

2012-12-19qdev-properties.c: Separate core from the code used only by qemu-system-*Eduardo Habkost
This separates the qdev properties code in two parts: - qdev-properties.c, that contains most of the qdev properties code; - qdev-properties-system.c for code specific for qemu-system-*, containing: - Property types: drive, chr, netdev, vlan, that depend on code that won't be included on *-user - qemu_add_globals(), that depends on qemu-config.o. This change should help on two things: - Allowing DeviceState to be used by *-user without pulling dependencies that are specific for qemu-system-*; - Writing qdev unit tests without pulling too many dependencies. The copyright/license of qdev-properties.c isn't explicitly stated at the file, so add a simple copyright/license header pointing to the commit ID of the original file.
