Best choice for I/O hub for AMD Opteron
by Craig C Forney 28 Apr '04

28 Apr '04

Looking for advice and counsel regarding LinuxBIOS support for I/O hub alternatives ... We've just completed a very dense cPCI dual Opteron design with an AMD 8111 as the I/O hub, no superIO, no 8131, no 8151, with 8GB SDRAM. LinuxBIOS seems to work fine, although the lack of legacy support for serial I/O was problematic (we ended up simulating a serial port). Thanks for everyone's support on helping us with early issues getting up to speed with LinuxBIOS. For our next generation, we would like to use a better supported and more integrated I/O hub than the 8111 (USB 2.0 doesn't work on the 8111, to start with). The nVidia nForce 3-2506B and the VIA K8T800 Pro seem to have a lot of potential, but I'm concerned about support for these from the manufacturers as far as LinuxBIOS is concerned. We don't mind helping with debug on any new code required, but we don't want to even start unless we have some confidence that there will be some level of support and effort behind our choice (and that we are not alone). Are there any opinions out there about these (or other) candidates related to LinuxBIOS? Any comments appreciated. Regards, Craig Forney Opus Innovations LLC Cupertino, CA

答复: LinuxBIOS Video?
by YhLu 28 Apr '04

To make the onboard ati rage xl framebuffer work under linux, you need patch for 2.4.22 and 2.6.5. the original ati framebuffer even not work under normal bios. In SUN sparc openboot and PowerPC MAC, I guess they are using framebuffer to show text for booting....---> they have limited display card. How about us, only support ati rage xl now. I wonder if we can enable framebuffer for add on display card so we can get output from crt via btext console. YH -----邮件原件----- 发件人: Hendricks David W.

Right now we can use ATi embedded devices (Rage XL) pretty well, some older stuff like on the SiS630, and EPIA whatever. But for newer stuff like GeForce cards, we have had to toggle some IORRs and stuff and run the VGABIOS after Linux is booted. From here, framebuffering can be used for console display and X can run fully accelerated in AGP8x with fast writes and side band addressing. This has only been tested by us on the Tyan S2885.

SMBus and HW monitor
by Li-Ta Lo 28 Apr '04

Ron, You copied some smbus and hw monitor code from hdama to e325. Are they correct on this board ? Is the hardware the same across those k8 boards ? Should we move it to some shared directory ? Ollie

Canonical order of dev_find_device()
by Li-Ta Lo 28 Apr '04

28 Apr '04

Eric, Is there any order for dev_find_device() ? In linux kernel, if there are two devices have the same vendor and device ID, the one with lower BUSDEVFN will be returned first and when the function is called again with the first returned device structure as parameter, the one with higher BUSDEVFN will be returned. Is it the same for LinuxBIOS ? There are some hard coded BUS_DEV_FNs for 8111/8131 bridges in mptable.c for all mainboards. Can we just search for these bridges by ID instead of the hardcoded values ? Ollie

Boot PC from Compact Flash
by manisha s 28 Apr '04

28 Apr '04

Hi All, I m new to this mailing list. I want to boot my laptop from 128Mb Compact Flash(CF) Card. On laptop i have already RedHat 9 with kernel version 2.4.22. I downloaded the pebble linux distribution and successsfully downloaded (wrote) this on to the CF. The CF card is available as /dev/sdb on the linux through CF card reader/writer. I changed /etc/grub.conf file so as to include the CF card title Pebble(Pebble) root (hd0,1) kernel /mnt/pebble/boot/vmlinuz-2.4.22-pebble ro root=/dev/sdb1 title Red Hat Linux (2.4.22) root (hd0,1) kernel /boot/vmlinuz-2.4.22 ro root=/dev/hda2 initrd /boot/initrd-2.4.22.img should i copy the vmlinuz-2.4.22-pebble to /boot directory? should i change other than this? plz shed some light on this issue?

re: Etherboot 5.2.4 + btext console + filo patch
by YhLu 27 Apr '04

27 Apr '04

To me filo is just like enhancement to Etherboot ide_disk.zelf. but it is more smart that it can understand file system and boot linux/initrd instead of elf. If we can put filo into Etherboot official tree, we can make use of the framework of Etherboot. For example in Etherboot you still can only produce filo.zelf, and it is less 32k now. I didn't enable the multiboot in filo of Etherboot yet.

There is enough appeal to the simplicity of FILO that we're not as interested (here anyway) in the etherboot integration. FILO is a small simple loader that does what it does well; Etherboot is a whole lot more complex. That does not mean I think merging it in is bad, but I also would like to see it maintain its seperate existence. ron

IBM/E325 problem fixed, other problems remain
by Li-Ta Lo 27 Apr '04

27 Apr '04

Hello, I fixed the problem of all device on bus 0. It was an undefined struct chip_control mainboard_ibm_e325_control, it is declared in chip.h but is not actually defined in mainboar.c. Ron forgot to change the name of the strucutre to ibm_e325 from arima_hdama. Now the questions, why didn't gcc complain about this ? If that line in chip.h is treated as "declaration" than missing the real definition in mainboard.c for the IBM/E325 before is an error. If that line in chip.h is a definition than the second definition in mainboard.c for all other mainboards is an error. Why does not gcc say anything ? Should I go back to school to learn C programming language again ? Ollie

Ron, Do you need to create contrib or payload dir to put such kind of patch. Because Etherboot group may not accept such kind of patch.

After add sth in filo_x.c, we can support simple menu.... Regards YH
