From 527bab0473f28236e4587c7870586275c1ef5516 Mon Sep 17 00:00:00 2001 From: Tilak Tangudu Date: Tue, 16 Nov 2021 21:22:38 +0530 Subject: [PATCH] drm/i915/rpm: Enable runtime pm autosuspend by default Let's enable runtime pm autosuspend by default everywhere. So, we can allow D3hot and bigger power savings on idle scenarios. But at this time let's not touch the autosuspend_delay time, what caused some regression on our previous attempt. Also, the latest identified issue on GuC PM has been fixed by commit 1a52faed3131 ("drm/i915/guc: Take GT PM ref when deregistering context") v1: Enable runtime pm autosuspend by default for Gen12 and later versions. v2: Enable runtime pm autosuspend by default for all platforms(Syrjala Ville) v3: Change commit message(Nikula Jani) Signed-off-by: Tilak Tangudu Reviewed-by: Rodrigo Vivi Signed-off-by: Rodrigo Vivi Link: https://patchwork.freedesktop.org/patch/msgid/20211116155238.3226516-1-tilak.tangudu@intel.com --- drivers/gpu/drm/i915/intel_runtime_pm.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/gpu/drm/i915/intel_runtime_pm.c b/drivers/gpu/drm/i915/intel_runtime_pm.c index eaf7688..f26ed142 100644 --- a/drivers/gpu/drm/i915/intel_runtime_pm.c +++ b/drivers/gpu/drm/i915/intel_runtime_pm.c @@ -600,6 +600,9 @@ void intel_runtime_pm_enable(struct intel_runtime_pm *rpm) pm_runtime_use_autosuspend(kdev); } + /* Enable by default */ + pm_runtime_allow(kdev); + /* * The core calls the driver load handler with an RPM reference held. * We drop that here and will reacquire it during unloading in -- 2.7.4
