From ddd66d63473513bb013928245b6482969b97de05 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Mon, 17 Apr 2023 10:27:08 -0500 Subject: platform/x86/intel/pmc: core: Report duration of time in HW sleep state MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit intel_pmc_core displays a warning when the module parameter `warn_on_s0ix_failures` is set and a suspend didn't get to a HW sleep state. Report this to the standard kernel reporting infrastructure so that userspace software can query after the suspend cycle is done.
