From 39f3a8b89fbd7589bb911d64f894c0c7d56fb694 Mon Sep 17 00:00:00 2001 From: Lakshmanan M Date: Wed, 15 Jun 2016 10:23:43 +0530 Subject: gpu: nvgpu: Add fifo conf support for gp10x Added fifo configuration support for gp104 and gp106. These GPU chips have more number of channel fifo and runlist than gp10b. Added get_num_fifos and eng_runlist_base_size function pointer to find out the actual value from HW headers.
