Intel Releases A Boatload Of Haswell Documentation

As an extra holiday present for Linux and open-source fans, Intel has quietly released a large batch of new programming documentation that covers their latest-generation Haswell graphics cores. The new "programmer's reference manuals" cover the 2013 Haswell HD Graphics, Iris Graphics, and Iris Pro Graphics. This massive batch of documentation is spread across twelve volumes and does document their hardware registers.

Intel Developer Finds 50 Watt Power Regression In Linux

An Intel Linux kernel developer has discovered that since the Linux 3.10 kernel one of his powerful Xeon-based systems is going through 50 Watts more energy while idling than on pre-3.10 kernels. This power regression could affect smaller systems too, but fortunately the issue has been bisected and an investigation is in process.
