Strange that it doesn’t support SPARC. It’s like Linux only supporting ARM64 and not x86.

There's an effort to support it: https://dlc.openindiana.aurora-opencloud.org/SPARC/

I think it doesn't have much support because the majority of SPARC gear out there runs better with SunOS. Solaris was a big jump up in processing requirements.

Ignoring 20 years of sparc hardware produced after the last sunos release.

Oracle doesn’t help much IIRC. SPARC seems to be a dead-end hardware-wise.

A real shame IMHO.

The improvements regarding memory tagging, the first UNIX architecture to ship memory tagging in production for years, has been done under Oracle management.

[palmfacehn]

Will they keep the architecture going forward with new chips?

[pjmlp]

SPARC is doing just fine for the context of existing Solaris customers.

ARM, RISC-V and CHERI have similar memory tagging capabilities for Linux/Windows users.

The elephant in the room are Intel/AMD not being able to deliver on that front, after several failed attempts.

[stonogo]

Yes, it's pretty clear everyone is. What's your point?

[tedunangst]

The majority of sparc gear out there doesn't run sunos at all, let alone better.
