Exposing the DMI L1 configuration as a kernel Kconfig option was in hindsight a really bad idea. It led to several errors reported by distributions which selected it by mistake. The Kconfig is now replaced with a kernel parameter. Since DMI L1 entry is incompatible with pause on a capture stream, the latter is disabled when the kernel parameter is set. Experimental results show an increased residency in higher C states and a significant decrease of system power consumption for "work from home" usages such as VoIP calls.
