    * PCIe retry on error
    * NVMe logging changes
    * NVMe attempts to boot twice
+   * Increase the maximum GPU memory size from 256MB to 512MB so long as
+     boot_ramdisk=0. This should only be used with the legacy camera
+     application and FKMS for very memory intensive camera operations.
