From 0901d0bc4c78313eaaf29dff74c6a7bf5514f75b Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Sat, 13 May 2017 11:02:22 -0700 Subject: [PATCH] i965: Round copy size to the nearest block in intel_miptree_copy The width and height of the copy don't have to be aligned to the block size if they specify the right or bottom edges of the image. (See also the comment and asserts right above). We need to round them up when we do the division in order to get it 100% right.
