From fb0a23ea168fd0947d9bc1064f91f15ef8a0c057 Mon Sep 17 00:00:00 2001 From: Terje Bergstrom Date: Fri, 19 Jan 2018 15:16:44 -0800 Subject: gpu: nvgpu: Implement gp10b variant of cbc_ctrl Pascal has support for more comptags than Maxwell, but we were using gm20b definitions for cbc_ctrl on all chips. Specifically field clear_upper_bound is one bit wider in Pascal. Implement gp10b version of cbc_ctrl and take that into use in Pascal and Volta.
