Phoronix: Linux Lands Fix For Potentially Bogus Number Of Intel Hybrid CPU HT Siblings

A few days ago I wrote about a Linux kernel patch being prepared for fixing Intel hybrid CPU SMP/HT topology reporting due to the way the Linux kernel was currently counting the number of Hyper Threading siblings for each core. Fortunately, that fix which is apparently becomes more pressing for upcoming Meteor Lake processors, has now been picked up in time for today's Linux 6.4-rc4 release and is set for back-porting to stable kernel series...

Here is an eerie idea to get the conspiracy theorists going.... *What if a 16 core CPU is actually just a single core, and each virtual core is just running at 1/16th the speed* .... Enjoy the show.

The article suggests this bug has been around a while.

Linus Torvalds already went ahead and merged the straight-forward patch for this change that was surprisingly overlooked until recently.

I am waiting for the day when someone starts tabulating "code quality" scores for all of the contributors to the Linux kernel...just so we can see who contributes the best and worst quality of code to the kernel.
