OpenSolaris ‘spork’ Illumos has decided to deprecate support for SPARC CPUs.
A README posted to GitHub says the decision to drop SPARC is rooted in the fact that the OS was written for silicon that hasn’t been sold for a decade.
“The most recent SPARC machines for which we have relatively direct and complete support were contemporary at the time of the fork; viz., the UltraSPARC T2 family of servers, such as the T5120 and T5220,” wrote Illumos core team member Joshua M Clulow. “The last of these systems reached their end-of-life between 2011 and 2012.”
