Phoronix: Linux 4.20~5.0 Bringing Better x86 32-Bit Hibernation Support

Intel's Rafael Wysocki sent in the power management updates today for the Linux 4.20~5.0 kernel cycle...

I don't think I will ever use a 32-bit machine again.
64-bit on desktop, laptop, tablet, phone and server.
64-bit on single-board computer (Raspberry Pi 3, etc).
Probably 64-bit on smartwatch and IoT.

there are still gorgeous 32-bit systems, e.g. the Sony Vaio P: https://www.youtube.com/watch?v=suCj4eulTJg not to mention nice vintage systems, like a SPARCstation 2: https://www.youtube.com/watch?v=A3O1YVUI9N4

Too bad the 32-bit architecture is dead! 32bit RIP

Mostly academic at this point, it would have been useful 20 years ago. I haven't had a 32bit system in nearly 15 years.

It's nice to have. I have a 32-bit-only laptop running a few feet away (2006-era Dell Inspiron E1505/6400).

Ironically, Windows 10 support for it recently cratered (it installs, the Windows logo appears, but no spinner).

Does anyone know which generations of processors this will affect?

Also the email is addressed to Linus, has he come back?

Maybe they will port Linux to the Intel Management Engine (currently running Minix). That's 32-bit, I think. On each and every modern Intel processor.

The other 32-bit Intel things have been discontinued, I think: 32-bit-only Atoms and the Quark. (The Quark might still be alive as the IME.)

Repeating myself: if they are working on this, they should fix this serious power management bug for Baytrail: https://bugzilla.kernel.org/show_bug.cgi?id=109051

There are a lot of 64-bit systems for which 32-bit Linux could make sense. There were a raft of netbooks and tablets with only 2G of RAM, many shipped with 32-bit UEFI (and no legacy mode). Code density matters for those resource-starved machines. But I cannot imagine that Intel would want to facilitate Linux on those systems.
