Increase nominal max votes to improve DDR performance and USB audio use case handling.
Currently, Bandwidth vote for max nominal value is set to 2500, requiring DDR to run at 1GHz under normal load.
DDR is allowed to run under nominal range at 1.5GHz, which is consistent across all targets. However, with the current nominal Increase nominal max votes to improve DDR performance and USB audio use case handling.
Currently, Bandwidth vote for max nominal value is set to 2500, requiring DDR to run at 1GHz under normal load.
DDR is allowed to run under nominal range at 1.5GHz, which is consistent across all targets. However, with the current nominal vote, glitches are observed during multiple audio use cases over USB. Update the nominal vote to allow DDR to run more
efficiently, enabling simultaneous multiple USB audio use cases without glitches.
With the existing vote, throughput is around 124MB/s. The updated nominal value increases throughput to 134MB/s.
With Updated Nominal value, we are seeing
Enhanced performance and stability for multiple USB audio use cases and improved overall system efficiency with higher throughput
