Linux 3.13 To Receive Multi-Queue Block Layer

While the Linux 3.13 merge window isn't opening until next week, the maintainer of the block layer to the Linux kernel isn't accepting anymore changes for this next kernel release. The merge pull for the block layer in Linux 3.13 is already quite large, in part due to merging the multi-queue block layer (blk-mq) support for faster disk performance. The multi-queue block layer will allow Linux to perform significantly better for disk IOPS while reducing latency with multi-queue SSD access on multi-core systems.

LLVM/Clang Is Advancing To Build The Linux Kernel

Going back years there's been work to build the Linux kernel with LLVM's Clang compiler rather than GCC. It's taken a lot of work by many individuals and organizations, but it's becoming an easier task to accomplish for multiple architectures. Here's where the Clang'ed Linux kernel is at today.

Ivy Bridge Graphics Benchmarks From Linux 3.12 Kernel

When running some Iris Pro 5200 graphics benchmarks we were surprised to see the Intel Linux 3.12 kernel changes didn't boost the performance at all given that it enables the 128MB of dedicated video memory. Additionally, within the forums there's been reports of Intel users seeing decreased performance out of the 3.12 kernel code. To clear up matters a bit, here's some Intel Ivy Bridge tests on Linux 3.12 compared to prior kernel releases.
