From 4fafba2d73fcaf1b433c26e753a98ad4b231754a Mon Sep 17 00:00:00 2001 From: Zhenyu Wang Date: Mon, 18 Dec 2017 11:58:46 +0800 Subject: drm/i915/gvt: move write protect handler out of mmio emulation function It's a bit confusing that page write protect handler is live in mmio emulation handler. This moves it to stand alone gvt ops. Also remove unnecessary check of write protected page access in mmio read handler and cleanup handling of failsafe case. v2: rebase Reviewed-by: Xiong Zhang Signed-off-by: Zhenyu Wang --- drivers/gpu/drm/i915/gvt/gtt.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'drivers/gpu/drm/i915/gvt/gtt.h') diff --git a/drivers/gpu/drm/i915/gvt/gtt.h b/drivers/gpu/drm/i915/gvt/gtt.h index f98c1c19b4cb..4cc13b5934f1 100644 --- a/drivers/gpu/drm/i915/gvt/gtt.h +++ b/drivers/gpu/drm/i915/gvt/gtt.h @@ -308,4 +308,7 @@ int intel_vgpu_emulate_gtt_mmio_read(struct intel_vgpu *vgpu, int intel_vgpu_emulate_gtt_mmio_write(struct intel_vgpu *vgpu, unsigned int off, void *p_data, unsigned int bytes); +int intel_vgpu_write_protect_handler(struct intel_vgpu *vgpu, u64 pa, + void *p_data, unsigned int bytes); + #endif /* _GVT_GTT_H_ */ -- cgit
