We currently have two module parameters that control GuC: "enable_guc_loading" and "enable_guc_submission". Whenever we need submission=1, we also need loading=1. We also need loading=1 when we want to want to load and verify the HuC. Lets combine above module parameters into one "enable_guc" modparam. New supported bit values are: 0=disable GuC (no GuC submission, no HuC) 1=enable GuC submission 2=enable HuC load Special value "-1" can be used to let driver decide what option should be enabled for given platform based on hardware/firmware availability or preference. Explicit enabling any of the GuC features makes GuC load a required step, fallback to non-GuC mode will not be supported. v2: Don't use -EIO Signed-off-by: Michal Wajdeczko <michal.wajdeczko@xxxxxxxxx> Cc: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> Cc: Joonas Lahtinen <joonas.lahtinen@xxxxxxxxxxxxxxx> Cc: Sagar Arun Kamble <sagar.a.kamble@xxxxxxxxx> Cc: Sujaritha Sundaresan <sujaritha.sundaresan@xxxxxxxxx>
