dt-bindings: interconnect: qcom-bwmon: Add Maili cpu-bwmon compatiblegrafted
Add the Qualcomm Maili SoC compatible string for the CPU bandwidth
monitor (BWMONv4). This falls back to the sdm845-bwmon compatible,
consistent with the existing pattern used by other recent SoCs such as
sm8750 and kaanapali.

SPDX-License-Identifier: GPL-2.0 + +======== +FAILOVER +======== + +Overview +======== + +The failover module provides a generic interface for paravirtual drivers +to register a netdev and a set of ops with a failover instance. The ops +are used as event handlers that get called to handle netdev register/ +unregister/link change/name change events on slave pci ethernet devices +with the same mac address as the failover netdev. + +This enables paravirtual drivers to use a VF as an accelerated low latency +datapath. It also allows live migration of VMs with direct attached VFs by +failing over to the paravirtual datapath when the VF is unplugged. |
