Qcude Driver With Mhi Support [repack] Review

Qcude supports MHI power state transitions. During periods of inactivity, the driver facilitates the transition of the modem to low-power states (M3), shutting down PCIe clocks to conserve battery life on mobile platforms.

The modem DMA-fetches the Transfer Ring Elements (TREs). qcude driver with mhi support

Holds descriptors for payload data transfers (TX/RX queues). Qcude supports MHI power state transitions

The interface relies on three core ring architectures managed in virtually contiguous memory: qcude driver with mhi support

Utilizing MHI's event ring capabilities, the Qcude driver configures interrupt coalescing timers. Instead of generating an interrupt for every packet, the modem waits for a timeout or a packet count threshold, reducing context switching overhead during high-load conditions.
