drm/amd/display: Skip entire amdgpu_dm build if !CONFIG_DRM_AMD_DC

2023-12-06T20:22:34+00:00

[WHY] Previously this only excluded build for a few amdgpu_dm binaries which makes no sense. [HOW] Wrap the entire Makefile in "ifneq ($(CONFIG_DRM_AMD_DC),)" Tested-by: Daniel Wheeler Reviewed-by: Alex Hung Signed-off-by: Harry Wentland Signed-off-by: Alex Hung Signed-off-by: Alex Deucher

drm/amd/display: Add Freesync Panel DM code

2023-08-07T21:14:07+00:00

We need certain conditions for replay to be enabled, so create an interface in DM to enable/disable replay. Signed-off-by: Bhawanpreet Lakha Reviewed-by: Harry Wentland Signed-off-by: Alex Deucher

drm/amd/display: Rename DCN config to FP

2023-03-07T19:22:40+00:00

[Why & How] The only reason we have the DCN config is for floating point support. Rename it to make that clear and (hopefully) avoid misuse of the config in the future.

drm/amd/display: Drop CONFIG_DRM_AMD_DC_HDCP

[Why & How] There is no reason we still need a config option for this. Reviewed-by: Wenjing Liu Acked-by: Qingqing Zhuo Signed-off-by: Harry Wentland Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: Create a file dedicated for CRTC

2022-07-25T13:31:01+00:00

[Why] The amdgpu_dm file contains most of the code that works as an interface between DRM API and DC. As a result, this file becomes very large since it comprises multiple abstractions such as CRTC manipulation. [How] This commit extracts the CRTC code to its specific file named amdgpu_dm_crtc. This change does not change anything inside the functions; the only exception is converting some static functions to a global function. v2: fix ifdef merge mix up (Alex) Tested-by: Daniel Wheeler Reviewed-by: Harry Wentland Acked-by: Alan Liu Signed-off-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

drm/amd/display: Add control mechanism for FPU

2021-08-06T01:17:59+00:00

DC invokes DC_FPU_START/END in multiple parts of the code; this can create a situation where we invoke this FPU operation in a nested way or exit too early. For avoiding this situation, this commit adds a mechanism where dc_fpu_begin/end manages the access to kernel_fpu_begin/end. Change since V3: - Christian: Move PPC64 code to dc_fpu_begin/end. Change since V2: - Christian: Do not use this_cpu_* between get/put_cpu_ptr(). Change since V1: - Use a better variable names - Use get_cpu_ptr and put_cpu_ptr to better balance preemption enable and disable Cc: Harry Wentland Cc: Anson Jacob Cc: Christian König Cc: Hersen Wu Cc: Aric Cyr Cc: Jun Lei Cc: Dmytro Laktyushkin Cc: Qingqing Zhuo Signed-off-by: Rodrigo Siqueira Reviewed-by: Christian König Signed-off-by: Alex Deucher
