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 --- 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",
