From 41e403d04e7050c8d88682939febcdbe117d4c82 Mon Sep 17 00:00:00 2001 From: Weinan Li Date: Wed, 21 Mar 2018 15:40:32 +0800 Subject: [PATCH] Revert "drm/i915/gvt: set max priority for gvt context" This reverts commit 11474e9091cf2002e948647fd9f63a7f027e488a. There are issues which will block the host preemption before, instead of disabling it use one workaround "setting max priority for gvt context" to avoid the gvt context be preempted by the host. Now the issues have been cleared, so revert this patch to enable host preemption. v2: - refine description(Zhenyu) Signed-off-by: Weinan Li Signed-off-by: Zhenyu Wang Signed-off-by: Zhi Wang --- drivers/gpu/drm/i915/gvt/scheduler.c | 3 --- 1 file changed, 3 deletions(-) diff --git a/drivers/gpu/drm/i915/gvt/scheduler.c b/drivers/gpu/drm/i915/gvt/scheduler.c index ffb45a9ee228..c2d183b91500 100644 --- a/drivers/gpu/drm/i915/gvt/scheduler.c +++ b/drivers/gpu/drm/i915/gvt/scheduler.c @@ -1156,9 +1156,6 @@ int intel_vgpu_setup_submission(struct intel_vgpu *vgpu) if (IS_ERR(s->shadow_ctx)) return PTR_ERR(s->shadow_ctx); - if (HAS_LOGICAL_RING_PREEMPTION(vgpu->gvt->dev_priv)) - s->shadow_ctx->sched.priority = INT_MAX; - bitmap_zero(s->shadow_ctx_desc_updated, I915_NUM_ENGINES); s->workloads = kmem_cache_create_usercopy("gvt-g_vgpu_workload", -- GitLab
