From 8e66e134e20b936179ea1535dd4ed19ec4f99dba Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 15 Oct 2014 17:20:55 -0400 Subject: [PATCH] drm/radeon: fix vm page table block size calculation The page offset is 12 bits. For example if we have an 8 GB VM, we'd need 33 bits. The number of bits needed for PD + PT is 21 (33 - 12 or log2(8) + 18), not 20 (log2(8) + 17). Noticed by Alexey during code review.
