Make sure that the (newer) /dev/pts/ptmx is accessible by users. This is useful e.g. when running containers which symlink /dev/ptmx to /dev/pts/ptmx on start. The default mode (000) does not allow to create ptys inside the container. Using 666 when symlinking /dev/ptmx is also recommended by the kernel documentation when /dev/ptmx is symlinked: https://www.kernel.org/doc/Documentation/filesystems/devpts.txt Also buildroot uses ptmxmode=0666. The patch introducing the change explains related use cases why this is necessary a bit more in depth: https://github.com/buildroot/buildroot/commit/8196b299ba12bd6741bf7f4462cad180dab77fb0#diff-2d4604b9e565eb19fa52ce31f282f06c (From OE-Core rev: c999bc5ddd9beb5274f77b885e2ac71205e42266) Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
