config EXYNOS_HDR_TUNABLE_TONEMAPPING bool "HDR Tuneable debugfs nodes for Tone mapping" ---help--- Creates hdr/tm_x and hdr/tm_y nodes under debugfs for overriding the tone mapping LUT coefficients configured in G2D and DPU with the values stored in the nodes. Configuring 33 integer values to both nodes immediately replaces the tone mapping LUT coefficients used by G2D and DPU. Writing 0 to one of both nodes stops overriding. This is just for display tunning purpose only for HDR videos. menu "Exynos Graphic Devices" source "drivers/gpu/exynos/g2d/Kconfig" endmenu
