From 71b0846c17b9c86ffa9a18f09f8cfda4fe41ee86 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 9 Jul 2019 17:54:26 -0700 Subject: drm/i915/guc: Remove preemption support for current fw MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Preemption via GuC submission is not being supported with its current legacy incarnation. The current FW does support a similar pre-emption flow via H2G, but it is class-based instead of being instance-based, which doesn't fit well with the i915 tracking. To fix this, the firmware is being updated to better support our needs with a new flow, so we can safely remove the old code. v2 (Daniele): resurrect & rebase, reword commit message, remove preempt_context as well Signed-off-by: Chris Wilson Signed-off-by: Daniele Ceraolo Spurio Cc: Chris Wilson Cc: Michal Wajdeczko Cc: Matthew Brost Cc: John Harrison Acked-by: Matthew Brost Reviewed-by: Michał Winiarski Link: https://patchwork.freedesktop.org/patch/msgid/20190710005437.3496-2-daniele.ceraolospurio@intel.com --- drivers/gpu/drm/i915/i915_drv.h | 2 -- 1 file changed, 2 deletions(-) (limited to 'drivers/gpu/drm/i915/i915_drv.h') diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index a9381e404fd5..2fa1d35efcb8 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -1378,8 +1378,6 @@ struct drm_i915_private { struct intel_engine_cs *engine[I915_NUM_ENGINES]; /* Context used internally to idle the GPU and setup initial state */ struct i915_gem_context *kernel_context; - /* Context only to be used for injecting preemption commands */ - struct i915_gem_context *preempt_context; struct intel_engine_cs *engine_class[MAX_ENGINE_CLASS + 1] [MAX_ENGINE_INSTANCE + 1]; -- cgit v1.2.3
