Move the IRAM code out of the shadows and into a new file modules/power/power_helpers.c The IRAM table contains the backlight curve and ABM parameters Add this new file to the Makefiles Call dmcu_load_iram in late init of DM Move struct dmcu_version from dc.h to dmcu.h to allow dmcu to be included on its own Signed-off-by: David Francis Reviewed-by: Harry Wentland Signed-off-by: Alex Deucher --- .../drm/amd/display/modules/power/power_helpers.h | 47 ++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 drivers/gpu/drm/amd/display/modules/power/power_helpers.h (limited to 'drivers/gpu/drm/amd/display/modules/power/power_helpers.h') diff --git a/drivers/gpu/drm/amd/display/modules/power/power_helpers.h b/drivers/gpu/drm/amd/display/modules/power/power_helpers.h new file mode 100644 index 000000000000..da5df00fedce --- /dev/null +++ b/drivers/gpu/drm/amd/display/modules/power/power_helpers.h @@ -0,0 +1,47 @@ +/* Copyright 2018 Advanced Micro Devices, Inc. + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in + * all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
