Linus Torvalds announced the release of Linux Kernel 5.12 last night. He wrote on lkml:

Thanks to everybody who made last week very calm indeed, which just makes me feel much happier about the final 5.12 release.

New Features in Kernel 5.12 include:

  • Intel VRR / Adaptive-Sync for Intel Xe.
  • Radeon RX 6800/6900 series OverDrive overclocking support.
  • Mainline support for the Nintendo 64
  • Sony PlayStation 5 DualSense controller driver.
  • CXL 2.0 Type-3 memory device support
  • Lenovo Laptop Platform Profile support.
  • Better Microsoft Surface device support.
  • And much more.

How to Install Linux Kernel 5.12:

The Ubuntu Mainline Kernel Archive provides the new kernel packages via DEB files.

The mainline build kernels do not include any Ubuntu-provided drivers or patches. They are not supported and are not appropriate for production use.

For those prefer using a graphical tool, see this tool to install the latest Kernel.
