My new provider IPv6 connectivity, however after connecting my OpenWrt based WNDR4300 (using Chaos Calmer 15.05-rc3) things unfortunately did not “just work”… This post summarize some hints how to debug IPv6 on OpenWrt.
First, make sure that the upstream (WAN) interface is configured according to the documentation in the OpenWrt Wiki. Using LuCI, you have to create a new interface (WAN6) which should c
The LLVMLinux team made quite some progress in enabling LLVM/clang to build the Linux kernel. There has also been a talk at the Collaboration Summit 2015 in Santa Rosa (slides). So I thought, give it a try and compile a kernel for my ARM based board of choice. The upstream kernel.org Linux kernel is not yet ready to be built using LLVM/clang, some patches are still required. Therefor I used the kernel from the LLVMLinux git server.
The nice thing about LLVM/clang is that it supports multiple targets. The binaries provided by the Arch repositories support several ARM targets:
$ pacman -S clang
$ llc --version
LLVM version 3.5.1
Built Jan 14 2015 (03:18:15).
Default target: x86_64-unknown-linux-gnu
Host CPU: core-avx-i
