This patch replaces the hardcoded "pi" user in the dtoverlay-pre and dtoverlay-post scripts with $SUDO_USER, which is set by the sudo command to the ID of the user calling it. In the event that SUDO_USER isn't set, $LOGNAME is used (set by login shells), with an ultime fallback to "pi". This change is necessary for users who have changed the login ID, perhaps as a security measure.
This repository contains the source code for the ARM side libraries used on Raspberry Pi. These typically are installed in /opt/vc/lib and includes source for the ARM side code to interface to: EGL, mmal, GLESv2, vcos, openmaxil, vchiq_arm, bcm_host, WFC, OpenVG.
Use buildme to build. It requires cmake to be installed and an arm cross compiler. It is set up to use this one: https://github.com/raspberrypi/tools/tree/master/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian
Note that this repository does not contain the source for the edid_parser and vcdbg binaries due to licensing restrictions.
