Intel E7000 / 82801CA and SPD
by David Hendricks 01 Aug '03

01 Aug '03

I'm having problems detecting memory on a SuperMicro P4DP6 mainboard using the scanspd utility. Using the spd_82801.c file in the util/scanspd directory, it returns "smbus_devfn not found!" After a few small modifications ( http://www.flagen.com/~sc/linux/lb/p4dp6/spd_82801ca.c ), it finds the SMBus but still can't seem to find any of the memory modules. Any ideas?

Eric, Great. Then there should be no big issue on opteron any more. Can you send to the new raminit.c to me now? Regards Yinghai Lu

Eric, Several Macro in console/console.h should be changed. For example: #define print_debug_hex8(HEX) printk_debug("0x08x", ((HEX)) #define print_debug_hex16(HEX) printk_debug("0x016x", ((HEX)) #define print_debug_hex32(HEX) printk_debug("0x032x", ((HEX)) to: #define print_debug_hex8(HEX) printk_debug("0x02x", ((HEX)) #define print_debug_hex16(HEX) printk_debug("0x04x", ((HEX)) #define print_debug_hex32(HEX) printk_debug("0x08x", ((HEX)) regards Yinghai Lu -----邮件原件----- 发件人: YhLu 发送时间: 2003年7月31日 20:44 收件人: ebiederman(a)lnxi.com 抄送: ron minnich; Stefan Reinauer; linuxbios(a)clustermatic.org 主题: 答复: Fixes for Tyan s2880 Eric, I see.

I shift by 12 instead of 10 for the low half of TOP_MEM2... Which tends to leave TOP_MEM2 at 4GB...

Eric, It works. For 6G. Tommorrow I will try 12G. Thanks.

Eric, I have checked your old k8/cpufixup.c, and it already has TOM2 etc setup. and SYSCFG_TOM2_EN...etc...

There has been enough code churn that my head is still spinning in trying to get in sync with the main tree. I have updated raminit.c so that it now handles the case of each memory controller starting from 0 cleanly, and I have updated cpufixup.c so that we are handling > 4GB of memory properly. TOP_MEM2 was not getting set to the proper value. fill_last was pretty much a duplicate of route_dram_access except different assumptions were made, so I have removed fill_last again. If you have memory that doesn't get setup properly now holler. So we should be pretty close. Before I can go much farther I need a test for pre rev c0 cpus. Because a lot of the remaining memory code needs to be conditional on it. I am in the last stages of stabilizing an internal version to be used in large scale testing to search for hardware incompatibilities. I also have a the links width and speed being automatically setup properly. But the way I discover the links is still kind of nasty, so I am not quite ready to push the code back yet. I should be switching over to the new configuration system on Monday and once that is sorted out quite I can start putting hard codes where they belong in the board specific configuration. Eric

Eric, I have made two changes in raminit.c 1. csbase counting 2. fill_last to make sure kernel to scan NUMA successfully. For s2880 it can work with 4*1G+2*256M RAM, and doesn't work with 4*1G+2*512M or 4*1G+2*1G. I would try to substitute raminit.c with hardcode one to test for 6G, if it can help. Please advise.

is there any way to boot linux without etherboot?
by gimyung han 31 Jul '03

31 Jul '03

I followed you HOWTO and succeed in Linux using LinuxBIOS with VGA Is there other way to boot Linux using LinuxBIOS without etherbooting? I saw message asking whether I will choose netbooting or local on the logging message? is option to choose the way to boot system? like local boot? If so, how to do that? do I need to load whole Linux kernel on the bios rom? lik using a DoC ? is anyone who boot Linux in other way on the EPIA mainboard? Thank for any help........... _________________________________________________________________ 도처에 도사리는 재해의 위험들.

static config for CPUs with K8 example
by ron minnich 31 Jul '03

31 Jul '03

OK, I am hoping this is the kind of thing that will work for the K8. First, in cpu/k8, define a file, chip.h: struct cpu_k8_config { struct chip *north, *south, *east, *west; }; Thenin cpu/k8/Config.lb, add this line: config chip.h Note this file could be called anything, but chip.h is a habit for me. In the mainboard config (mainboard/arima/hdama/Config.lb), you set things up as follows: southbridge amd/amd8111 "amd8111" end southbridge amd/amd8131 "amd8131" end # pull in all includes, etc. for the k8. # should we have a 'noise keyword' for this, e.g. 'cputype k8'? dir /cpu/k8 # define the CPUs, their names, and their connections. cpu k8 "cpu0" register "north" = "amd8111" register "east" = "cpu1" end cpu k8 "cpu1" register "north" = "amd8131" register "west" = "cpu0" end This will result in initialized structures, per-cpu, that "do the right thing". I've hit a bug I have to ask Greg about, but this is a rough idea. Comments? ron

Ron, If the 8111 is connected to 8131. Should add the config for 8131 and say its north is "amd8111".
