Debian Wiki SunSparc SunSparc Debian Wiki Sub Flavors Sun4c Sun4m Sun4d Sun4u UltraSPARC Sun4v Ultra Enterprise Debian Support Architecture Tidbits See Also There are a bunch They can generally be divided into 32 bit old and 64 bit new 32 bit has been broken in 2 4 due to lack of hackers on old machines In general the IO subsystem is much more robust on Sun machines than their contemporary Intel counterparts with the exception of the Ultra 5 10 system which has a broken IDE implementation in general always opt for SCSI or SATA SAS if available instead of IDE on the machines that have it See full list on wiki debian org Support for sun4c was dropped in Linux 3 5 anyone playing with these should stick with 2 2 2 6 series kernels The last Debian release with support is pre Sarge after that it is broken A custom kernel may work with up to Etch but that is uncharted territory The earliest supported 32 bit architecture but some early exotic sun4c machines might not work this is primarily a kernel issue Includes SPARCstation 1 aka ss1 2 IPC IPX ELC Read the Sun Hardware Faq at more information on these and older machines Linux doesn 39 t run as fast as NetBSD on these machines Linux doesn 39 t use the hardware context storage correctly there was a recent DaveM post to linux kernel about this and he doesn 39 t feel like fixing it Someone else may be working on it though See full list on wiki debian org Sun4m support is retained in recent kernels but receives little testing the maintenance burden is low as the code is mature The CPUs implement Sparc V8 and are mostly the same as modern Sparc CPUs except many modern implementations implement some of Sparc V8 from the 64bit spec as it adds the CASA instruction which is important for thread synchronization sun4m is a much more civilized class of 32 bit SPARCs Includes SS4 5 LC Classic LX ZX and SS10 20 and clones such as those by Tatung and Ross including the SparcPlug and Ross Hyperstation line These chips can be found used as either uniprocessor workstations multiprocessor SS10 20 and HyperStation which are SMP machines with up to four processors on removable mbus cards Speeds are up to 200 MHz in Ross Hypersparc mbus processors Equivalent performance to a Pentium Classic but with better FP Tadpole SPARCbook 3 laptops are in this class Framebuffers from bwtwo to 24 bit 1600x1200 are available SBUS expansion cards See full list on wiki debian org Sun4d is the funky class of 32 bit SPARCs that implement 8 procs via xdbus The xdbus originated at Xerox and came to Sun as a collaborative effort Only partially supported by Linux Sun4D also supports as much as 16GB RAM in the CS6400 5GB RAM in SS2000 and SS1000 e which supports up to 2GB SS1000 e supports up to 8 CPUs SS2000 supports 16 CPUs and Cray CS6400 Amdahl SuperSummit 6400E supports 64 CPUs The SparcServers and SparcCenter models use standard MBUS CPUs while the CS6400 machines use a custom module The multi xdbus SS2000E and CS6400 Supports up to 2MB cache per module while the single xdbus machines only support 1MB a 2MB module will show as 1MB if installed Only SuperSparc processors are supported no HyperSparc support for xdbus the fastest CPU is the 90Mhz SM 91 2 which is rare SM 81 or SM 61 is a more common cpu in these machines 85 and 65Mhz respectively In any case for most applications an SM81 is falls somewhere between a 142 180Mhz HyperSp See full list on wiki debian org 64 bit SPARCs SPARCstation Ultra 1 2 5 10 30 60 80 and Enterprise 250 450 1000 etc Up to 32 or 64 way SMP on these machines but the processors themselves are at the moment anyhow slower than the fastest P4s or Athlons though they may be a hair faster clock per clock they only go up to 1600MHz But you buy these machines for the seamless scalability to 32 way Some models accept SBUS PCI and PCIe expansion cards These are very well supported though individual framebuffers or other peripherals may not be See full list on wiki debian org 64 bit SPARCs These mainly extended virtualization support past what previous architectures supported Sun4d could partition the physical machine Sun4v allows virtual partitioning Virtualization is as yet still unsupported on Linux though Linux can run in an LDOM as a guest This series begins with the T1 Niagra which has 4 threads per core and only 1 FPU per socket T2 bumps this to 8 threads per core and 1FPU per core T3 extends multi sockets support T4 implements out of order execution Successive releases mostly increase frequency and cache as well as add acceleration hardware such as DAX for database acceleration The VII and up series have always focused on single thread performance unlike the T series which was focused on throughput both have converged in recent years See full list on wiki debian org SPARC is one of the most mature Debian ports officially supported since DebianSlink 1999 For details see 1 PortsSparc See full list on wiki debian org SPARC is one of the more unusual architectures It 39 s RISC but instead of just having a lot of registers like Alpha or MIPS it has a unique hardware linked list of 40 to 520 register windows depending on implementation of which you can see a 16 register window at any one time If the windows exceed what the hardware implements then a trap occurs to spill to main memory In general the architecture is extremely fast for floating point operations but suffers on any computation that relies on the stack overmuch memory bandwidth has historically not been fantastic which Sun has remedied by advanced cache architecture The machines themselves are extremely well engineered and specified all the Sun specific internals are IEEE standards including the SPARC ISA Sbus the bus in older SPARCs newer use PCI etc etc See full list on wiki debian org The mandatory wikipedia page The Authority on sun4c and some sun4m systems and configurations The Authority on sun4m processors and
