From 2af70854609509adf5dc92af2fcf1c30938e2a5d Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Tue, 28 Nov 2017 08:30:50 -0800 Subject: [PATCH] i965: Use old_bo->align when growing batch/state buffer instead of 4096. The intention here is make the new BO use the same alignment as the old BO. This isn't strictly necessary, but we would have to update the 'alignment' field in the validation list when swapping it out, and we don't bother today. The batch and state buffers use an alignment of 4096, so this should be equivalent - it's just clearer than cut and pasting a magic constant. Fixes: 2dfc119f22f257082ab0 "i965: Grow the batch/state buffers if we need space and can't flush."
