From mboxrd@z Thu Jan 1 00:00:00 1970 From: Michael Pruznick Date: Thu, 25 Jan 2001 17:17:26 +0000 Subject: Linux Status for Sun Netra T1 200 Message-Id: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ultralinux@vger.kernel.org I've been doing Linux (x86/ppc) for some time now, but I'm new to both the Sun product line and Linux on Sparc. Is this list and www.ultrasparc.org the main place to be for latest Linux on Sparc support? If not, please point me to the correct place. By searching the archives its pretty clear that Linux runs on at least some versions of the Netra and Ultra Sparc IIi processor. I don't have any Sun/Sparc boxes yet, but expect to be getting some soon. I expect my first box to be a Sun Netra T1 200. The Sun h/w page listed the following features that are of interest to me. I'm hoping someone on this list could help me understand what chipsets are on the box for these devices and what the status of linux support is. I suspect that some of the answers are in the Sun doc but my downloads keep stalling about about 20-40%. UltraSparc IIi appears to be a 64-bit processor? Does linux run as a 32 or 64 bit kernel? Does the 64-bit kernel run both 32 and 64 bit apps? The FAQ has pointers to what appears to be Solaris based cross development tools. Are there any existing tools out there will run on my Redhat 6.2 host? How do I boot my linux kernel? Will the f/w let me do a dhcp/tftp (or similar) to download my kernel from my x86 host which will also be the root nfs host for development? What is the pci bridge/memory controller chipset? Is it fully initialized by f/w? What is the memory map? For deployment, stand alone boot will be required. Will the f/w let me boot from a local scsi disk? What about user flash? Will f/w let me store/boot an initrd kernel image from a flash device? What type of bus is the PCI slot? 33 or 66 MHz? 32 or 64 bits? Any special list of cards that do or do not work with Sparc? Does the f/w do the bus walk, assign bars and INTLINE properly? If not, does linux already do this on Sparc? What is the serial uart chip? One of these is the console. Is the other available for kgdb or is part of the remote control? Are the ports DB-9 or do I need to make sure I order a special cable? What is the ethernet chipset? Any important features of the chipset that are or are not support on UltraLinux? What kind of numbers should I expect to get with netperf or ttcp(?)? What is the SCSI chipset and support? Is scsi the only disk/cd interface or is there an IDE interface? What is the USB controller? Is Sparc USB support the same as x86 or different? Does the 2.2.14/16??? USB patch enable work on Sparc as it does on x86? Are the alarm, status led, and remote control interfaces fully supported? For anything that is not supported, especially alarm, led, remote, is the reason just because someone doesn't have the need/time or is it because the doc is not available from Sun? Is the NEBS/3 certification a h/w ruggedness only, or does it require s/w to do anything? That is, does running Linux on the box cause it to loose its NEBS/3 certification?
