Linux 5.16-rc3 Released With Alder Lake ITMT Fix, Other Driver Fixes
In today's 5.16-rc3 announcement, Torvalds noted, "So rc3 is usually a bit larger than rc2 just because people had some time to start finding things. So too this time, although it's not like this is a particularly big rc3. Possibly partly due to the past week having been Thanksgiving week here in the US. But the size is well within the normal range, so if that's a factor, it's not been a big one."
Notable with Linux 5.16-rc3 is the ITMT fix affecting some Intel Alder Lake systems that with some motherboards could lead to improper P vs. E core selection. That is now fixed although the cluster-aware scheduling may still be causing some issues with 5.16.
Another notable "fix" this week is getting FUTEX2 futex_waitv working on more CPU architectures.
The rest of Linux 5.16-rc3 is largely the usual assortment of bug fixing.
Linux 5.16 stable should be out around the tail end of the calendar year. See our Linux 5.16 feature overview for a look at the major features of this forthcoming kernel. Additional Linux 5.16 benchmarks and other performance investigations ongoing.
