Linux framebuffer example• The framebuffer is a volatile memory used to store pixel data of the image to be displayed. This memory is usually called the graphic RAM (GRAM). The required size of the framebuffer depends on the resolution and color depth of the display. See Section 4.2.1: Framebuffer memory size requirements and location for more The framebuffer (fbdev) is a character device providing access to graphics hardware. Beside the framebuffer, other interfaces exist to access graphics hardware such as the DRI (direct rendering interface) or proprietary interfaces (NVIDIA drivers). Typically, the framebuffer doesn't support any 2D/3D hardware acceleration.Linux Framebuffer (without requiring a GPU) Applications can choose between 2 APIs for rendering - GLFBDev (OpenGL Extension to the Linux Framebuffer) based on Mesa legacy infrastructure - EGL for Linux Framebuffer platform based on Mesa Gallium3D infrastructureThis example shows instrumenting the kernel tcp_sendmsg () function on the Linux 3.9.3 kernel: # perf probe --add tcp_sendmsg Failed to find path of kernel module.
