From 8e2454c562ce9e6d06ba5e39c8e03097d3590c0e Mon Sep 17 00:00:00 2001 From: Abdiel Janulgue Date: Fri, 25 Jan 2013 15:37:00 +0200 Subject: [PATCH] intel: Account for mt->offset in intel_miptree_map We need to take account the offset from original bo when using glTexSubImage() and other functions that manipulate the subregion of an exported texture. Offsets are appended to mapped region address and when blitting from a source region.
