More CXL Additions Arrive For Linux 6.12

([Hardware] 3 Hours Ago Compute Express Link)


Ahead of the Linux 6.12 merge window wrapping up this weekend with the Linux 6.12-rc1 release, merged on Friday were all of the Compute Express Link (CXL) updates for the new kernel.

Intel engineers continue carrying out much of the CXL enablement for the mainline Linux kernel. For Linux 6.12 the CXL subsystem has seen HDM decoder initialization from DVSEC ranges, refactoring of CXL mailboxes code, support for shared upstream link access coordinate calculation, removing locking on the memory notifier callback, and other changes. No super shiny features this cycle but a lot of continued code churn for getting the CXL Linux support into good shape with more servers coming to market with CXL capabilities.

More details on the CXL Shared Upstream Link Calculation and other changes with Linux 6.12 can be found via [1]this Git merge .

Separately and not for Linux 6.12, posted this week by an Intel engineer were new [2]RFC patches on preparing the Linux kernel CXL core for CXL Type2 accelerators.

Well, anyway, I was reading this James Bond book, and right away I realized
that like most books, it had too many words. The plot was the same one that
all James Bond books have: An evil person tries to blow up the world, but
James Bond kills him and his henchmen and makes love to several attractive
women. There, that's it: 24 words. But the guy who wrote the book took
*thousands* of words to say it.
Or consider "The Brothers Karamazov", by the famous Russian alcoholic
Fyodor Dostoyevsky. It's about these two brothers who kill their father.
Or maybe only one of them kills the father. It's impossible to tell because
what they mostly do is talk for nearly a thousand pages. If all Russians talk
as much as the Karamazovs did, I don't see how they found time to become a
major world power.
I'm told that Dostoyevsky wrote "The Brothers Karamazov" to raise
the question of whether there is a God. So why didn't he just come right
out and say: "Is there a God? It sure beats the heck out of me."
Other famous works could easily have been summarized in a few words:

* "Moby Dick" -- Don't mess around with large whales because they symbolize
nature and will kill you.
* "A Tale of Two Cities" -- French people are crazy.
-- Dave Barry
