The 5.6 kernel has been released

[Posted March 29, 2020 by corbet]

Linus has released the 5.6 kernel.

Some of the headline features in this release include Arm EOPD support, time namespaces, the BPF dispatcher and batched BPF map operations (both described in this article), the openat2() system call, the WireGuard virtual private network implementation, the flow queue PIE packet scheduler, nearly complete year-2038 support, many new io_uring features, the pidfd_getfd() system call, the ZoneFS filesystem, the ability to implement TCP congestion-control algorithms in BPF, the dma-buf heaps subsystem, and the removal of the /dev/random blocking pool.

See the LWN merge-window summaries (part 1 and part 2) and the (under construction) KernelNewbies 5.6 page for more details.

FYI iwlwifi was broken in a late merge, there is a fix =)

Thank you, that saved me some potential trouble.

Following up, according to https://www.phoronix.com/scan.php?page=news_item&px=L... the fix is on 5.6.2.

If you have a AMD GPU you need to fetch mainline and cherry-pick 6de18fa3bd1dd5114106abf6217587d6f6cb051d to avoid linker errors

Adding to this, 0199172f9333 (in 5.6) fixes a kernel memory corruption in 5.5 that was extremely easy to provoke (as easy as running `clinfo`).

After installing Kernel 5.6 I am getting this error:

Cannot run in framebuffer mode. Please specify busIDs for all framebuffer devices

This used to work just fine, with Version 5.5, Gentoo/Funtoo Linux.

Very strange.

I would suggest trying to provide the missing firmware that both logs are complaining about first, and see if that fixes it...

Now trying again on Kernel 5.7.
