From cbc5d3f34b87db779829eabc90c32780a3865a56 Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Tue, 25 Apr 2023 15:48:46 +0200 Subject: soc/intel: Don't report _S1 state when unsupported Since skylake Intel hardware does not support this sleep state. Trying to enter S1 by having the OS enter sleep results in a system hang on at least Alder lake (prodrive/atlas). CONFIG_SOC_INTEL_COMMON_BLOCK_PMC is a good proxy whether devices support 'skylake style' PMC PCI device for ACPI registers.
