From be3750bc9eb60f8696c20b7298cc282eea17ac1b Mon Sep 17 00:00:00 2001 From: Terje Bergstrom Date: Wed, 27 Sep 2017 13:21:44 -0700 Subject: gpu: nvgpu: Abstract IO aperture accessors Add abstraction of IO aperture accessors. Add new functions gk20a_io_exists() and gk20a_io_valid_reg() to remove dependencies to aperture fields from common code. Implement Linux version of the abstraction by moving gk20a_readl() and gk20a_writel() to new Linux specific io.c. Move the fields defining IO aperture to nvgpu_os_linux. Add t19x specific IO aperture initialization functions and add t19x specific section to nvgpu_os_linux.
