Why devices ARE or NOT on bus 0 ?
by Li-Ta Lo 26 Apr '04

26 Apr '04

Hello guys, How does the enumeration decide if the devices in 8111/8131 are on bus 0 or other bus ? Isn't that all these non-coherent devices are on PCIDEV(0,0,0), at power up ? How are they changed to their "real" PCIDEVFN ? We are having problems on ibm/e325 that these devices remain on bus 0 such that the current HT and PCI scan or resource allocation is totally fucked. The devices are on bus 0 device 1 or something, these devices are enumerated first than the northbridge so the northbridge does not get correct information about its "link" and can not set IO/MEM/BUS routing correctly (actually it refuse to set at all). Does anyone can help on this ? Ollie

Via Epia-MII BiosSavior problems
by Ignacio Verona 26 Apr '04

26 Apr '04

Hi! Just a few minutes ago I've built my first linuxbios romimage. This week, I bought a RD1-PL BiosSavior for my MB (PLCC socket) and installed it. For all this week, the BiosSavior has been working, with the switch on "ORG" position, and correctly loading factory bios. And, for writing my new BIOS to the "backup" memory of the BiosSavior, I did put the switch to the RD1 position, and then #./flash_rom romimage. Ok, it seems to be well written to the memory, but before trying to load the new linuxbios I wanted to boot using the old and... It will not boot!! With the switch on ORG position, using the serial console, I can see LinuxBios boot up, but I hangs (this does not worry my at this time), but the only way I can boot my mobo is removing the biossavior and installing the original flash chip into the original socket... Did I bought the wrong BiosSavior? What happens?? Thanks.

I have talked to the LSI two times. I have asked our HW engineers to use adapted chip except special customer requirement. Adaptec don't need download FW into it.

答复: PVR with LinuxBIOS. What board is recommended? Some questions

S2850 would be better that s2880. It only takes one CPU. YH -----邮件原件----- 发件人: Hendricks David W.

My feelings > say "yes", don't they? Vendors haven't exactly been the most cooperative with sharing VGABIOS info. But we do have video working at least on the EPIA, SiS630, and now the Rage XL chips that come on server boards like the S2885 and HDAMA. However, you probably want something more powerful than those. We don't have nVidia or ATi Radeon support coming up from the get-go just yet, but so far we've been able to start a GeForce FX vgabios with 8x AGP support on a Tyan S2885. This is done with an x86 emulator that runs the vgabios after LinuxBIOS has already started. > 3.

You can boot your kernel from pretty much anywhere. If your flash part is big enough, you can put a kernel on it. Otherwise, you can boot off an ide hard disk, compact flash, or over the network. > 4. Is it correct that kernel 2.4.19 is the latest one supported by > LinuxBIOS? Should the patches be good for 2.4.26 also? What about 2.6? You can run any kernel. We're currently running 2.6.5 on our Opteron systems. > Maybe you can recommend some motherboards out of the box that are still > available in the shops? They should support CPUs with about 1200 MHz, HOw much did you want to spend on the thing? If you want fast, you might want to try a Tyan S2880, as YhLu has that working with VGA (Rage XL). It also has plenty of PCI slots, and will take dual Opterons. _______________________________________________ Linuxbios mailing list Linuxbios(a)clustermatic.org http://www.clustermatic.org/mailman/listinfo/linuxbios

So I need disable the code always, and don't send the image to the end user. What's pity!

If you can't publish the source then distributing the binary with the code compiled from that source linked in violates the GPL. Eric

amd opteron dram controller
by HC Wang 26 Apr '04

26 Apr '04

Hi, I am working on post code for an embedded opteron board, I have some problem with dram controller initialization, problem I have seen are (1) after setting DramInit bit (bit 8) in dram configuration low register (bus 0, dev 24, func 2, reg 0x90), processor clear this bit after a while but DramEnable (bit 10) and MemClrStatus (bit 11) never set high, is this a problem? If so what is causing it? (2) After DramInit bit is cleared by processor, I can access sdram from 0x00000000 to 0x0009ffff, fill it with pattern and verify it. But I can't write into address space from 0x000A0000 - 0x000EFFFF, even MTRRs associated with it are set to UC type. Is this correct? (3) Can't write memory above 1M (from 0x00100000 and up), but I can alter the memory content by using AMD HDT.. Any ideas? Thanks, HC

I will change the code to disable the lsi_scsi as the default. Do you have lsi 1030 onboard? You need to use it? If you need to use it, I send you pre-built image, because I can not publish the source code of lsi_scsi. LSI don’t want to.

When I using the new config to deal with it, the tool seems doesn’t support expression. I will check that in current config tool.

OK, BTW you can do this: option ROM_SIZE = 512*1024 - 48*1024 which is not as readable as 512k-48k, but is pretty readable. ron

When enabling lsi_scsi support, It need leave 48k in the BIOS ROM for lsi_scsi fw. So need to change normal mode ROM_SIZE to 512k-48k. After that, cat fwx, normal linuxbios, fallback linuxbios to 512k final image.

1. In freebios2/src/mainboard/tyan/s2880/Config.lb comment out dir ../common/lsi_scsi 2. In freebios2/targets/tyan/s2880/Config.lb comment out option ROM_SIZE = 475136 Don't forget 2. otherwise the final image will short some.
