Installation

• To compile mesa requires makedepend installed on your Host:

• Choose Mesa

Requires GPM too !!

• copy some demo or examples on your target:

$ cp buildroot/build_armvXX/Mesa-7.0/progs/demos/gears /tftpboot/

# cd
# mkdir -p mesa/demos/
# cd mesa/demos/
# tftp -g -r gears 192.168.1.2  (Host IP)

Usage

• Prevent framebuffer from going to sleep and cursor from blinking:

# echo -e '\033[9;0]' > /dev/tty1
# echo 0 > /sys/class/graphics/fbcon/cursor_blink

• Launch your demos:

# cd mesa/demos/
# ./gears
....
Defaulting to stdin input
48 frames in  5.034 seconds =  9.535 FPS

• With only ~10fps (on APF27), you will learn that ARM9 cores without 3D nor Floating points unit really suffer to render 3D scenes in software.
• Demo will take control of the serial console. To quit each demo, press "ESC" on your console.
