From: Tvrtko Ursulin <[email protected]> WaEnableStateCacheRedirectToCS context workaround configures the L3 cache to benefit 3d workloads but media has different requirements.
Remove the workaround and whitelist the register to allow any userspace configure the behaviour to their liking. v2: * Remove the workaround apart from adding the whitelist.
