Hi, My current system configuration is like application gives the frame to XORG and XORG is configured to use simple frame buffer driver(mapped to DDR address). I need to implement a ping pong buffer utility in such a way that every new frame goes to two different DDR addresses. I can reserve two block of memory in simple frame buffer driver adding below mentioned code in system-user.dtsi: chosen { framebuffer0: framebuffer@3ee48000 { compatible = "simple-framebuffer"; memory-region = <&frontbuff_reserved> <&backbuff_reserved>; width = <1280>; height = <800>; stride = <5120>; format = "a8r8g8b8"; status = "okay"; };
}; reserved-memory { #address-cells = <2>; #size-cells = <2>; ranges; frontbuff_reserved: framebuffer@3ee48000 { no-map; reg = <0x0 0x3ee48000 0x0 0x400000>; }; backbuff_reserved: framebuffer@3f248000 { no-map; reg = <0x0 0x3f248000 0x0 0x400000>; }; }; But I need some support in how XORG can use these two memory alternatively on every frame/image at runtime. I have attached the xorg log file and conf file for reference. Regards, Prija ________________________________ Please be advised that this email may contain confidential information.
