NOTE: recent commit from YhLu
by ron minnich 25 Jul '03

25 Jul '03

I have just committed the changes from YhLu which he sent this morning. The following files are changed: CVS: src/include/device/pci_ids.h src/mainboard/tyan/s2880/Config CVS: src/mainboard/tyan/s2880/auto.c CVS: src/mainboard/tyan/s2880/failover.c CVS: src/mainboard/tyan/s2880/tyan-fallback.config CVS: src/mainboard/tyan/s2880/tyan-normal.config CVS: src/northbridge/amd/amdk8/coherent_ht.c CVS: src/northbridge/amd/amdk8/raminit.c CVS: src/southbridge/amd/amd8111/Config CVS: src/southbridge/amd/amd8111/Config.lb CVS: src/southbridge/amd/amd8131/amd8131_bridge.c Note that most of this is s2880-specific, with only a few mods to the amd chip files. The next step is to add options for the new config tool to enable mainboard-specific functions to be called. Please make sure your K8 ports still work. I can send the results of a c-diff on request. ron

2 quick changes to arima/hdama

I've temporarily bumped up debugging output inside that file (the romimage gets too big otherwise) and shrunk the size of the tested memory region until I can get it to run faster. ron

Good, I will use your new config tool for s2880. -----邮件原件----- 发件人: ron minnich [mailto:rminnich@lanl.gov] 发送时间: 2003年7月24日 16:07 收件人: YhLu 抄送: ebiederman(a)lnxi.com; Stefan Reinauer; linuxbios(a)clustermatic.org 主题: Re: K8 + 2.4.21 + Tyan S2880 YhLu: I can fix your problem without adding the mainboard init function to hardware main, and also without code like this to the include file: ==== #ifdef FINAL_MAINBOARD_FIXUP void final_mainboard_fixup(void); #else # define final_mainboard_fixup() do {} while(0) #endif /* FINAL_MAINBOARD_FIXUP */ ==== All I need to do is add an enable function for the mainboard into the static device tree, and create a structure for your mainboard in the mainboard/tyan/2880 directory. This is pretty easy, and will let us test out the new static device support. But, if I make this change you are going to have to use the new config tool for your mainboard. There is no going back to the old config tool once I make the change. The new config tool is working pretty well, now, however: Greg and Stefan and I are using it, and Greg and I use it exclusively. There are still some glitches here and there but overall it is quite solid. Is this acceptable to you? Stefan, Greg, and I can help you with any problems you encounter with the new config tool. thanks ron

Ron, I find the problem. Can you merge the diff the tree? 1. in raminit.c, when computing csbase, should recount from 0 for every memory controllers. Otherwise the memory on second northbridge will not be init properly and can not be used. 2. add start/stop notify function. ( in coherent_ht.c and auto.c) Otherwise when using image that was compiled in non debug mode for auto.c, the second cpu can not be started. Thanks.

Here are my findings: 1. Use the most updated code, in the Etherboot stage it will reboot after firt NIC try aborting. 2. I have try to subsutite mem-conf with hard code version, and found another problem, I can not start AP after conherent_ht or memory initization. Only can start and stop in enable_routing function. 3. I have to move back to old code ( Before Eric moved some definition from romcc_io.h to arch/io.h and cpu/p6/msr.h). At this situation, if I use mem-conf, it still can not find broadcom nic in etherboot stage. But after I substitute mem init with hard code one, It can find the nic. I will study the difference today. But anyway what make I can not start AP after conherent_ht or memory init, so strange ???

But it meet problems in Etherboot stage. In S2880 has two broadcom NIC port in 8131 bus B, and one amd 8111 built-in nic, and even if I hide it in amd8111 init and Etherboot can find it and try to enable it and can not find the PM cap so aborting, in the old linuxbios code (before yesterday) ( with mem hard code), it will go to tickle on Broadcom nic, but in the new code (yesterday check in) ( mem configurable), it will go to MB restarting.??? How about arima broadcom nic position?

What happened? Only add one line and the same function has been > called ??? All functions are inline and the set of functions called is large. At least I believe that is the issue. And good luck catching up.... While I am away you get a chance. My latest code has changed sdram_initialize one more time to take a cpu count parameter. And perversely this should help because if a function is called in a loop it will only be inlined once instead of multiple times. Eric

new config tool, static and dynamic trees
by ron minnich 24 Jul '03

24 Jul '03

Greg has implemented the static tree/dynamic tree code mentioned yesterday, and today it passed its first test with flying colors. Greg needed some ide setup done on the southbridge to make his IDE interface work. To effect the change, he had to have certain code execute at a certain pass in the platform startup. Turned out the code could execute once PCI was configured. His code in the mainboard Config.lb did not change: southbridge winbond/w83c553 end That's it. But the C code for the southbridge had the CONF_PASS_POST_PCI code added for configuration: void southbridge_init(struct chip *chip, enum chip_pass pass) { struct southbridge_winbond_w83c553_config *conf = (struct southbridge_winbond_w83c553_config *)chip->chip_info; switch (pass) { case CONF_PASS_POST_PCI: w83c553_init(); break; default: /* nothing yet */ break; } } The tail end of the code looks like this: struct chip_control southbridge_winbond_w83c553_control = { enable: southbridge_init, name: "Winbond W83C553" }; This last bit is the chip_control structure, the "class definition" code for this part. So, in short, it was trivial to set up, and showed, at least to us, that this is a good direction. ron

AMD package/part numbers
by Greg Watson 24 Jul '03

24 Jul '03

Any idea how to translate an AMD package number to an AMD part number? I have a flash part that is marked D323GB90V1 but I can't find anything on the AMD site that helps translate this to a part number, short of reading every data sheet. Thanks, Greg

Flash memory?
by John Praveen 24 Jul '03

24 Jul '03

Hi I read the document www.linux-magazine.com/issue/28/LinuxBIOS.pdf. It states that DiskOnChip is required for the linuxBIOS. The How-to doc in linuxbios tree too is based on building it for DiskOnChip. Thats what i was confused whether my Flash device would be supported or not? __________________________________ Do you Yahoo!? Yahoo!

anybody? ron ---------- Forwarded message ---------- Date: Wed, 23 Jul 2003 03:12:33 +0000 From: Devi Priya <ijpriya(a)hotmail.com> To: rminnich(a)lanl.gov Subject: SC1200-BLDT Hello I have compiled the linuxbios for sc1200. I also have Dorado xpress loader. Can you plz tell how could I boot my linux OS from Flash into RAM using the BLDT from National? I assume the BLDT is for WindowsCE OS. I assume like this. I can have the (lilo) bootloader as the option ROM. So my BIOS program shall scan for the option ROMs. Is it correct? _________________________________________________________________ It's all happening @ F1.
