From 1c66a12ab431cda82a1dc53fc0bcd54370014755 Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Tue, 6 Sep 2022 16:49:29 -0700 Subject: [PATCH] drm/i915: Handle each GT on init/release and suspend/resume In preparation for enabling a second GT, there are a number of GT/uncore operations that happen during initialization or suspend flows that need to be performed on each GT, not just the primary, Cc: Daniele Ceraolo Spurio Signed-off-by: Matt Roper Reviewed-by: Daniele Ceraolo Spurio Link: https://patchwork.freedesktop.org/patch/msgid/20220906234934.3655440-10-matthew.d.roper@intel.com Signed-off-by: Joonas Lahtinen --- drivers/gpu/drm/i915/i915_driver.c | 59 +++++++++++++++++++++--------- 1 file changed, 42 insertions(+), 17 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_driver.c b/drivers/gpu/drm/i915/i915_driver.c index d513ee690dc3..07f51a973783 100644 --- a/drivers/gpu/drm/i915/i915_driver.c +++ b/drivers/gpu/drm/i915/i915_driver.c @@ -310,8 +310,13 @@ static void intel_detect_preproduction_hw(struct drm_i915_private *dev_priv) static void sanitize_gpu(struct drm_i915_private *i915) { - if (!INTEL_INFO(i915)->gpu_reset_clobbers_display) - __intel_gt_reset(to_gt(i915), ALL_ENGINES);
