I'm probably jumping the gun as they have only recently been announced but what support is available for the RMI XLR Family of Thread Processors? The RMI web site is http://www.razamicroelectronics.com. The following snippets have been lifted from documents available from that web site: "XLR-enhanced 64-bit MIPS64 ISA" [1]. "an operating system such as Linux requires no software changes to allow it to run as a multi-way SMP operation system on the XLR processor. This allows software engineers to develop code while leveraging the same standard tool chains and operating systems that have been use in the past development efforts" [2]. "ArizonaATX-I is initially enabled by two standard operating systems including 32-bit Linux 2.6 with complete support for the XLR processor. Full source code is available and SMP support is standard. Customers will have early access to RMI's kernel improvements" [3]. -- John Connett [1] "RMI XLR Processor Family Product Brief", Document # PB2001, Raza Microelectronics, Inc..
