From 7c28135c77414327523b89bfc3f13096e095f5ac Mon Sep 17 00:00:00 2001 From: "Zhao, Xinda" Date: Tue, 21 Feb 2017 15:54:56 +0800 Subject: [PATCH] drm/i915/gvt: remove unnecessary error msg from gtt write The guest VM may initialize the whole GTT table during boot up, so the warning msg in emulate_gtt_mmio_write is not necessary, it is the expected behavior and it may confuse the user if error msg is printed out, so remove the msg from emulate_gtt_mmio_write(), Signed-off-by: Zhao, Xinda Signed-off-by: Zhenyu Wang --- drivers/gpu/drm/i915/gvt/gtt.c | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) diff --git a/drivers/gpu/drm/i915/gvt/gtt.c b/drivers/gpu/drm/i915/gvt/gtt.c index b5c833287d39..6a5ff23ded90 100644 --- a/drivers/gpu/drm/i915/gvt/gtt.c +++ b/drivers/gpu/drm/i915/gvt/gtt.c @@ -1825,11 +1825,8 @@ static int emulate_gtt_mmio_write(struct intel_vgpu *vgpu, unsigned int off, gma = g_gtt_index << GTT_PAGE_SHIFT; /* the VM may configure the whole GM space when ballooning is used */ - if (WARN_ONCE(!vgpu_gmadr_is_valid(vgpu, gma), - "vgpu%d: found oob ggtt write, offset %x\n", - vgpu->id, off)) { + if (!vgpu_gmadr_is_valid(vgpu, gma)) return 0; - } ggtt_get_guest_entry(ggtt_mm, &e, g_gtt_index); -- 2.20.1
