Configures interrupt moderation and event ring sizing.
As the demand for high-throughput, low-latency wireless connectivity increases, the interface between the host processor and the modem subsystem becomes a critical bottleneck. This paper explores the architectural design of the driver, a proposed kernel-space interface driver, and its integration with the Modem Host Interface (MHI) . By leveraging MHI’s standardized channel management and ring buffer protocols, the Qcude driver provides a robust, asynchronous communication pipeline for next-generation data cards. This document details the software stack, memory management, and the specific advantages of utilizing MHI over legacy proprietary interfaces. qcude driver with mhi support
