From f7bbe7883c3f119714fd09a8ceaac8075ba04dfe Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 19 Aug 2016 16:54:27 +0100 Subject: [PATCH] drm/i915: Embed the io-mapping struct inside drm_i915_private As io_mapping.h now always allocates the struct, we can avoid that allocation and extra pointer dance by embedding the struct inside drm_i915_private Signed-off-by: Chris Wilson Reviewed-by: Joonas Lahtinen Link: http://patchwork.freedesktop.org/patch/msgid/20160819155428.1670-5-chris@chris-wilson.co.uk --- drivers/gpu/drm/i915/i915_gem.c | 6 +++--- drivers/gpu/drm/i915/i915_gem_execbuffer.c | 2 +- drivers/gpu/drm/i915/i915_gem_gtt.c | 11 +++++------ drivers/gpu/drm/i915/i915_gem_gtt.h | 2 +- drivers/gpu/drm/i915/i915_gpu_error.c | 2 +- drivers/gpu/drm/i915/intel_overlay.c | 4 ++-- 6 files changed, 13 insertions(+), 14 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_gem.c b/drivers/gpu/drm/i915/i915_gem.c index 0e1f5dde2e87..5398af7f7580 100644 --- a/drivers/gpu/drm/i915/i915_gem.c +++ b/drivers/gpu/drm/i915/i915_gem.c @@ -891,7 +891,7 @@ i915_gem_gtt_pread(struct drm_device *dev, * and write to user memory which may result into page * faults, and so we cannot perform this under struct_mutex. */ - if (slow_user_access(ggtt->mappable, page_base, + if (slow_user_access(&ggtt->mappable, page_base, page_offset, user_data, page_length, false)) { ret = -EFAULT;
