Linux kernel 3.8 highlights


  • CPU-hotplugging. The Linux kernel will support hot-swapping all cpus. As of now, you can replace all cpus but the first one. So it will be possible to replace all cpus without a reboot. This neat!
  • The old 386 platform support will be removed. Probably not missed by many, but still, I thought Linux would run forever everywhere, which it may actually do for a while still, but it will be more difficult.
  • Support for the Haswell integrated graphics from Intel. I'm glad intel helps with working on the kernel.
  • The Noveau driver takes a few steps forward with better powermode handling for NVIDIA cards.
  • KVM virtualization support for ARM to use the Kernel-based Virtual Machine with ARM Cortex-A15 cores. This will help development of modern ARM-devices surely.
  • Improved ACPI power management, to make battery times in laptops better. This has been a drawback for some time now.

These are just a small part of the features that are likely to be included in the 3.8 version.
