From 304d2a7fc8acc1bb337596e0fc301092ea079b4d Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 21 Mar 2016 08:07:44 -0300 Subject: [PATCH] [media] tw686x-kh: specify that the DMA is 32 bits Set vb2_queue.gfp_flags to GFP_DMA32. Otherwise it will start to create bounce buffers which is something you want to avoid since those are in limited supply.
