Lina Iyer 723feab600 ANDROID: GKI: QoS: Enhance framework to support cpu/irq specific QoS requests ... QoS request for CPU_DMA_LATENCY can be better optimized if the request can be set only for the required cpus and not all cpus. This helps save power on other cores, while still gauranteeing the quality of service. Enhance the QoS constraints data structures to support target value for each core. Requests specify if the QoS is applicable to all cores (default) or to a selective subset of the cores or to a core(s), that the IRQ is affine to. QoS requests that need to track an IRQ can be set to apply only on the cpus to which the IRQ's smp_affinity attribute is set to. The QoS framework will automatically track IRQ migration between the cores. The QoS is updated to be applied only to the core(s) that the IRQ has been migrated to. Idle and interested drivers can request a PM QoS value for a constraint across all cpus, or a specific cpu or a set of cpus. Separate APIs have been added to request for individual cpu or a cpumask. The default behaviour of PM QoS is maintained i.e, requests that do not specify a type of the request will continue to be effected on all cores. Requests that want to specify an affinity of cpu(s) or an irq, can modify the PM QoS request data structures by specifying the type of the request and either the mask of the cpus or the IRQ number depending on the type. Updating the request does not reset the type of the request. The userspace sysfs interface does not support CPU/IRQ affinity.
