Abstract: Examples include updating firmware for a persistent memory module in a computing system during runtime. Examples include downloading firmware to the persistent memory module; saving settings of one or more input/output (I/O) devices of the computing system and setting a timeout value of the one or more I/O devices to greater than a time to activate the firmware in the persistent memory module. Examples include updating the firmware in the persistent memory module during runtime of the computing system by quiescing access to one or more memory modules of the computing system; sending a request to the persistent memory module to activate the firmware; waiting for the request to activate the firmware to be completed by the persistent memory module; and un-quiescing access to the one or more memory modules of the computing system; and restoring the saved settings for the one or more I/O devices.
