    摘要: Methods and apparatus for live migration for hardware accelerated para-virtualized IO devices. In one aspect, a method is implemented on a host platform including a VMM or hypervisor hosting a VM with a guest OS and a hardware (HW) input/output (TO) device implemented as a para-virtualized IO device with hardware acceleration that is enabled to directly write data into guest memory using a direct memory access (DMA) data path via a HW accelerator. A relayed data path including a software (SW) relay is setup between the HW IO device and a guest IO device driver. During a live migration of the VM, the SW relay tracks memory pages in guest memory being written to by the HW IO device via the DMA data path and logs the memory pages being written to as dirty memory pages. Embodiments may employ Vhost Data Path Acceleration (VDPA) for virtio, as well as other para-virtualization components.

    摘要: Methods and systems for equalization of a first receiver. A method may include receiving an input signal at the first receiver. The method may also include receiving the input signal at a second receiver. The method may further include determining, from an output response of the second receiver, an estimate of an out-of-channel interferer present in the input signal. The method may also include determining an estimate, of an undesired in-channel response of the first receiver to the out-of-channel interferer present in the input signal. The method may include applying the estimate, of the undesired in-channel response of the first receiver to the out-of-channel interferer present in the input signal, to an output signal of the first receiver to substantially cancel an instance of an undesired in-channel response of the first receiver to the out-of-channel interferer.
