+ | === 5. Tips and tricks === | ||
+ | |||
+ | == 5.1. Processor == | ||
+ | |||
+ | The Raspberry Pi processor can reach 1.2GHz. | ||
+ | However, by default, it is stuck to 600MHz even if it is used at 100%. | ||
+ | You can check the current frequency of the processor by typing: | ||
+ | < | ||
+ | |||
+ | In order to reach 1.2GHz when the processor is used at 100% (i.e., use the frequency scaling), you need to change the default governors. | ||
+ | Add the following line to the end of the '' | ||
+ | < | ||
+ | Now, the processor is correctly set. | ||
+ | |||
+ | == 5.2. Time == | ||
+ | |||
+ | Unfortunately, | ||
+ | That is why there are no battery included with the board. | ||
+ | It means that each time you shutdown the Raspberry Pi, the time is reset! | ||
+ | However, if you have internet access, you can update the time during the Slackware ARM boot. | ||
+ | Add the following line to the end of the ''/ | ||
+ | < | ||
+ | Now, the time is correctly set. | ||
+ | |||
+ | == 5.3. Video == | ||
+ | |||
+ | Unfortunately, | ||
+ | It means that, by default, each application requiring OpenGL will be slow. | ||
+ | However, you can reach 60 FPS with OpenGL applications on the Raspberry Pi by using the correct driver. | ||
+ | |||
+ | Firstly, you need to build Mesa (>= 17.0.4) with the VC4 DRI driver: | ||
+ | < | ||
+ | $ CFLAGS=" | ||
+ | CXXFLAGS=" | ||
+ | ./configure \ | ||
+ | --prefix=/ | ||
+ | --sysconfdir=/ | ||
+ | --with-dri-driverdir=/ | ||
+ | --with-egl-platforms=x11, | ||
+ | --with-gallium-drivers=vc4 | ||
+ | $ make -j4 | ||
+ | $ make install DESTDIR=/ | ||
+ | </ | ||
+ | Then build your own Slackware ARM Mesa package | ||
+ | |||
+ | Secondly, add the following line to the end of the ''/ | ||
+ | < | ||
+ | Then reboot the Raspberry Pi. | ||
+ | |||
+ | You can check that you are able to get 60 FPS with OpenGL applications on the Raspberry Pi by typing the following | ||
+ | < | ||
+ | |||
+ | Now, the video is correctly set. | ||
