Interesting stuff on my old world macs
I've been doing some testing. I have a PowerMac 9600/300 now. The processor is a 300Mhz 604ev, which has 1MB L2 cache on the daughtercard running @ 100Mhz. I also picked up a Sonnet G3/400/1M card. Here are some of the results: OldWorld PowerMac 9600/300 604ev @300Mhz w/ 1MB L2 Cache @ 100Mhz ATI Rage II(Mach 64 GT) (XCLAIM3D) 4MB PCI Card 390Watt Power Supply Adaptec 2940UW PCI SCSI Card(flashed with the Mac ROM) 192MB RAM(6 x 32MB DIMMs) Mac OS v9.1 results for Processor: Apple System Profiler: External L2 cache: 1MB Hardware overview: Machine ID: 67 Model name: Power Macintosh 9600 series Keyboard type: Apple Extended Keyboard Processor info: PowerPC 604ev Machine speed: 300 Mhz KInfoCenter results for Processor: processor 0 cpu 604ev clock 300Mhz revision 1.0 (pvr 000a 0100) bogomips 299.00 machine Power Macintosh motherboard AAPL,9500 MacRISC detected as 16 (PowerMac 9500/9600) pmac flags 00000000 L2 cache 256K unified memory 192MB pmac-generation Old World Sonnet Cresendo G3 400/1M PCI Processor Upgrade card(note that I do not have any extentions or software in use for the G3 card, nor do I know if I actualy need any). Mac OS v9.1 results for Processor: Apple System Profiler: Total L2 cache: External L2 cache: 8MB Backside L2 cache: 0MB Hardware overview: Machine ID: 67 Model name: PowerMacintosh 9600 series Keyboard type: Apple Extended Keyboard Processor Info: PowerPC G3 Machine speed: 445Mhz BootX GrabG3CacheSetting utility results: Querying CPU family... Getting value of G3 L2CR register ... L2CR value is: 0x00000000, saving... done. The "Set G3 Cache" option in BootX should now be available. KInfoCenter results for Processor: processor 0 cpu 740/750 temperature 31-33 C (uncalibrated) clock 50Mhz revision 130.2 (pvr 0008 8202) bogomips 796.67 machine Power Macintosh motherboard AAPL,9500 MacRISC detected as 16 (PoerMac 9500/9600) pmac flags 00000000 L2 cache 256K unified memory 192MB l2cr override 0x0 pmac-generation Old World dmesg results for the G3 upgrade card: <6>L2CR overriden (0x0), backside cache is disabled dmesg results for BOTH processor cards: <4>device-tree: property "l2-cache" name conflicts with node in /PowerPC,60? As you can see, Linux incorrectly identifies the L2 cache value for both processors as 256k. Also, the dmesg results for the G3 card say that the backside cache is diabled. I am still running v10.0/RC1, so I dunno if the release version would be any different. Is there something wrong with these results, or is there something I am doing wrong? The bogomips for the G3 would be consistent with a 400Mhz processor, but the Mac OS shows that the G3 is running at 445Mhz w/ 8MB L2 cache.......weird.

there must be a some tool for MacOS that sets the L2CR register (L2 cache configuration). Check the Sonnet website. 8MB L2 sounds wrong. -- short story of a lazy sysadmin: alias appserv=wotan
-----Original Message----- From: Olaf Hering <olh@suse.de> there must be a some tool for MacOS that sets the L2CR register (L2 cache configuration). Check the Sonnet website. 8MB L2 sounds wrong. I have all of the Sonnet software installed. Sonnet's website says that the OS 9 profiler will not properly show the specs, but their Metronome utility does show it properly. However, of more of a concern to me is that Linux shows BOTH the G3/400/1M and the 604ev/300/1m as only having 256k L2 cache. I can verify that the G3's backside cache is working because the L2CR shows it now that I have installed the Sonnet software under OS 9, but the 604ev's L2 cahce is considered "In-Line". It's cache is on the processor card, and runs at 100Mhz(instead of being on the Motherboard and running at 50Mhz). I have looked at the NetBSD and other BSD boards and there has been some similar comments about the 604ev. ___________________________________________________ Try the New Netscape Mail Today!
