Kernel Log: Coming in 3.10 (Part 3)

Filed under
Linux

For Linux 3.10, the kernel developers have modified code designed to protect Samsung laptops from faults caused by a problem with garbage collection in the UEFI firmware. The changes mean that the previously sometimes over-eager protection feature, which had occasionally blocked machines from other manufacturers from setting or modifying UEFI variables, will swing into action less frequently. A recent test by c't magazine, for example, found that several test machines were missing UEFI entries for booting the installed Linux OS following UEFI Linux installation, due to UEFI entry creation having been blocked by this feature. Users can solve situations like this by using efibootmgr on a LiveCD Linux, such as Fedora 18 or Ubuntu 12.10, that doesn't contain the code to protect Samsung notebooks and manually create a UEFI boot entry; obviously this option should not be used with a Samsung device. Details of the approach adopted by the revised protection feature can be found in a blog entry by kernel developer Matthew Garrett.

Tickless

Linux can now slow the timer interrupt for individual CPU cores, which normally fires 100, 250 or 1000 times per second, to just one interrupt per second.

  • LibRetro's Vulkan PlayStation PSX Renderer Released
    A few days back I wrote about a Vulkan renderer for a PlayStation emulator being worked on and now the code to that Vulkan renderer is publicly available. For those wanting to relive some PlayStation One games this week or just looking for a new test case for Vulkan drivers, the Vulkan renderer for the LibRetro Beetle/Mednafen PSX emulator is now available, months after the LibRetro folks made a Vulkan renderer for the Nintendo 64 emulator.
  • Etnaviv DRM Updates Submitted For Linux 4.10
    The Etnaviv DRM-Next pull request is not nearly as exciting as MSM getting Adreno 500 series support, a lot of Intel changes, or the numerous AMDGPU changes, but it's not bad either for a community-driven, reverse-engineered DRM driver for the Vivante graphics cores.
  • Mesa 12.0.4 Being Prepped For Ubuntu 16.10/16.04
    Ubuntu is preparing Mesa 12.0.4 for Ubuntu Xenial and Yakkety users. It's not as great as Mesa 13, but at least there are some important fixes back-ported. Mesa 12.0.4 is exciting for dozens of bug fixes, including the work to offer better RadeonSI performance. But with Mesa 12.0.4 you don't have the RADV Vulkan driver, OpenGL 4.5, or the other exciting Mesa 13 work.
