From 26487b82df0c6604cc40fd6480f7ad7ed4e3efb0 Mon Sep 17 00:00:00 2001 From: Deepak Nibade Date: Thu, 1 Jun 2017 13:32:09 +0530 Subject: gpu: nvgpu: move clk_gm20b debugfs to Linux module Move debugfs code from clk_gm20b.c to file in Linux module common/linux/debug_clk.c This file will be compiled only if CONFIG_DEBUG_FS is set Define below new HAL APIs for various clock operations which can be accessed from debug file init_debugfs() get_voltage() get_gpcclk_clock_counter() pll_reg_write() get_pll_debug_data() Export nvgpu_pl_to_div() and nvgpu_div_to_pl() so that these can be accessed from debug_clk.c Add new structure nvgpu_clk_pll_debug_data so that all required register values for debugging can be made available in debug_clk.c Add new API gm20b_get_gpc_pll_parms() so that statically defined variable can be accessed in debug_clk.c too Remove global variable dvfs_safe_max_freq and add it to struct clk_gk20a so that it can accessed from both clk_gm20b.c and debug_clk.c Jira NVGPU-62 Change-Id: I3ae70b40235e78141a686686930e1f178ad59453 Signed-off-by: Deepak Nibade Reviewed-on: http://git-master/r/1488903 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom --- drivers/gpu/nvgpu/gk20a/clk_gk20a.h | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/gpu/nvgpu/gk20a/clk_gk20a.h') diff --git a/drivers/gpu/nvgpu/gk20a/clk_gk20a.h b/drivers/gpu/nvgpu/gk20a/clk_gk20a.h index 65f82263..e8c14e43 100644 --- a/drivers/gpu/nvgpu/gk20a/clk_gk20a.h +++ b/drivers/gpu/nvgpu/gk20a/clk_gk20a.h @@ -97,6 +97,7 @@ struct clk_gk20a { bool clk_hw_on; bool debugfs_set; int pll_poweron_uv; + unsigned long dvfs_safe_max_freq; }; #if defined(CONFIG_COMMON_CLK) -- cgit v1.2.2
