Linux for SPARC release 1.0 is a reference platform incorporating Oracle's work to improve Linux on modern SPARC hardware. The kernel is based on the mainline 4.1 kernel, while user-space packages are consistent with Oracle Linux 6 for x86_64 with a few exceptions. Both the kernel and some user space packages include SPARC-specific optimizations.
