From: Kenneth Graunke Date: Thu, 1 Aug 2013 22:35:35 +0000 (-0700) Subject: i965: Move GL_APPLE_object_purgeable functionality into a new file. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=76c2533470ec805fdb45592c72becd632d8bf6d4;p=mesa.git i965: Move GL_APPLE_object_purgeable functionality into a new file. GL_APPLE_object_purgeable creates a mechanism for marking OpenGL objects as "purgeable" so they can be thrown away when system resources become scarce. It specifically applies to buffer objects, textures, and renderbuffers. The intel_buffer_objects.c file provides core functionality for GL buffer objects, such as MapBufferRange and CopyBufferSubData. Having texture and renderbuffer functionality in that file is a bit strange. The 2010 copyright on the new file is because Chris Wilson first added this code in January 2010 (commit 755915fa). v2: Actually remember to call the new dd table setup function.
