[Xen-devel] [PATCH]Make IDE dma tranfer run in another thread in qemu
Originally in qemu when a IDE dma transfer is started which is triggered by access to 0xc000 port in VMX, qemu will blocked there until it finished. And during that block, there are extra dom switches between dom0 and idle domain, and VMX can''t be resumed. By making real IDE dma tranfer run in another thread, qemu will return and VMX resume on time and there are fewer cycle wasted.
