From 96ea753d9eb802c95544c79035e89df38daf15f7 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Fri, 27 May 2016 15:00:57 +1000 Subject: [PATCH] i965: report bound buffer size not underlying buffer size for image size (v2) This seems to make sense, the image is bound to a subset of the buffer so the image size should be from the bound size not the underlying object. This fixes: GL44-CTS.shader_image_size.advanced-nonMS-fs-int v2: get mininum of the two values, same as we write to the hw.
