Key facts

  • SPARC is big-endian
  • SPARC can come in both 32-bit and 64-bit flavors
  • SPARC is notoriously strict on aligned access to memory; unaligned accesses often lead to SIGBUSes being sent. See bug #371525.
  • Our current developer hardware is catbus (previously we had bender).

Keywording policy

ARCH=sparc has best-effort stable keywords: both stage3s and the installcd use stable packages.

Please keep adding sparc@ to the CC list for STABLEREQs if sparc already has stable keywords for a package.


We are currently looking for users interested in helping the project with one or more jobs.
