[PATCH 0/2] remoteproc: qcom_q6v5_mss: Fix MDM9607 subsystem control instance ID

From: Stephan Gerhold

Date: Mon Jul 06 2026 - 13:49:44 EST


Currently, trying to shutdown the modem firmware on MDM9607 results in the
following error:

qcom-q6v5-mss 4080000.remoteproc: timeout waiting for ssctl service

This is because qcom_q6v5_mss defines the wrong instance ID for the QMI
subsystem control service of the modem firmware. Make this configurable per
platform and fix the issue by defining the correct ssctl_id for MDM9607.
