From 893315d49ed678de95cf6ac553efb6093cc7343c Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Sat, 16 Aug 2008 11:35:10 -0700 Subject: i915: set domain properly on fb mapping, flush out changes The user visible ioctl does this, but since we call into GEM internals directly, we have to flush things ourselves. Fixes initial fb console corruption. --- linux-core/intel_fb.c | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'linux-core/intel_fb.c') diff --git a/linux-core/intel_fb.c b/linux-core/intel_fb.c index ce8ac3d9..c1391c0a 100644 --- a/linux-core/intel_fb.c +++ b/linux-core/intel_fb.c @@ -716,12 +716,18 @@ int intelfb_create(struct drm_device *dev, uint32_t fb_width, uint32_t fb_height obj_priv = fbo->driver_private; mutex_lock(&dev->struct_mutex); + /* Flush everything out, we'll be doing GTT only from now on */ + i915_gem_object_set_domain(fbo, I915_GEM_DOMAIN_GTT, + I915_GEM_DOMAIN_GTT); + ret = i915_gem_object_pin(fbo, PAGE_SIZE); if (ret) { DRM_ERROR("failed to pin fb: %d\n", ret); goto out_unref; } + i915_gem_clflush_object(fbo); + fb = intel_user_framebuffer_create(dev, NULL, &mode_cmd); if (!fb) { DRM_ERROR("failed to allocate fb.\n"); -- cgit v1.2.3
