Re: [LinuxBIOS] Fwd: [issue50] put pgtbl after 1M
by Lu, Yinghai 08 Dec '05

Regarding the problem there are three way to solve. 1. move the pgtbl after 1M. this should work for a while.... the future 32 node abd quad core = 128 cpu, will have stack 128*8=1M, It will cross the 0xa000 again... 2. in linuxbios_ram.ld, force bss, stack and heap all after 1M, the total ram section will be larger then 1M (about 1.5M), (linuxbios_ram.bin still about 64K), it works well except the back and forth in two linuebios ram image in jmp_to_elf_entry will clear the 0xf0000-0x100000, the irq table ( and acpi region ) region 3. the best solution seems to set _RAMBASE=0x10400, so it will not clear our irq table and acpi tables...., the only thing to do is some 16 bit code in secondary.S need to move to rom....other wise the ap can not be started....

[LinuxBIOS] How to reset Geode GX1/CS5530 board
by joep＠frog.nl 07 Dec '05

07 Dec '05

I am working to get LinuxBIOS (v2) running on an embedded board with a Geode GX1 CPU and CS5530A companion device. To my joy, the board is already happily booting LinuxBIOS and running the linux kernel: after a little bit of tuning it races from power on to Linux prompt in 3 seconds!! Great job, linuxbios programmers! I have 2 questions: 1) I would like to be able to do a reboot (reset) and/or poweroff from software. Does anybody know how to get this done for this hardware? I don't know if the reset interface is standard or dependent on specific board design. I tried writing 0x1 to i/o port 0x92 (as suggested in the CS5530A data book), but is does not work. 2) I noticed that in my configuration the cache is not turned on. That made the booting of the kernel very slow. I worked around this by calling "enable_cache" in auto.c, but I guess this is not the right way to do it. I see there is x86_enable_cache in cpu/amd/model_gx1/model_gx1_init.c:model_gx1_init(), but this function is never called. Here is the boot log from LinuxBIOS: ----- 0.000: 0.011: LinuxBIOS-1.1.8.0Fallback ma dec 5 15:04:24 CET 2005 starting... 0.020: Setting up default parameters for memory 0.236: Sizing memory 0.241: Probing for DIMM0 0.245: Found DIMM0 0.251: Page Size: 00001000 0.256: Component Banks: 4 0.259: Module Banks: 1 0.267: DIMM size: 04000000 0.269: Probing for DIMM1 0.273: MC_BANK_CFG = 00701420 0.577: Copying LinuxBIOS to ram. 0.632: Jumping to LinuxBIOS. 0.641: LinuxBIOS-1.1.8.0Fallback Mon Dec 5 19:41:22 CET 2005 booting... 2.265: clocks_per_usec: 413 2.273: Enumerating buses... 2.274: Finding PCI configuration type. 2.275: PCI: Using configuration type 1 2.280: PCI_DOMAIN: 0000 enabled 2.281: PCI: pci_scan_bus for bus 0 2.288: PCI: 00:00.0 [1078/0001] enabled 2.296: PCI: 00:02.0 [1282/9102] enabled 2.296: PCI: 00:12.0 [1078/0100] enabled 2.297: PCI: 00:12.1 [1078/0101] enabled 2.302: PCI: 00:12.2 [1078/0102] enabled 2.310: PCI: 00:12.3 [1078/0103] enabled 2.311: PCI: 00:12.4 [1078/0104] enabled 2.312: PCI: 00:13.0 [0e11/a0f8] enabled 2.319: PNP: 002e.0 enabled 2.325: PNP: 002e.1 enabled 2.326: PNP: 002e.2 enabled 2.326: PNP: 002e.3 disabled 2.327: PNP: 002e.4 enabled 2.327: PNP: 002e.5 enabled 2.337: PNP: 002e.6 enabled 2.338: PNP: 002e.7 enabled 2.338: PNP: 002e.8 disabled 2.340: PCI: 00:12.1 disabled 2.341: PCI: 00:12.2 enabled 2.367: PCI: 00:12.3 disabled 2.368: PCI: 00:12.4 disabled 2.369: PCI: pci_scan_bus returning with max=00 2.371: done 2.373: Allocating resources... 2.374: Reading resources... 2.378: Done reading resources. 2.379: Setting resources... 2.380: BC_DRAM_TOP = 0x03bfffff 2.386: MC_GBASE_ADD = 0x00000078 2.387: I would set ram size to 60 Mbytes 2.389: PCI: 00:02.0 10 <- [0x0000001000 - 0x00000010ff] io 2.390: PCI: 00:02.0 14 <- [0x00febc2000 - 0x00febc20ff] mem 2.397: PCI: 00:02.0 30 <- [0x00feb80000 - 0x00febbffff] romem 2.400: PCI: 00:12.1 10 <- [0x00febc3000 - 0x00febc30ff] mem 2.408: PCI: 00:12.2 20 <- [0x0000001400 - 0x000000147f] io 2.416: PCI: 00:12.3 10 <- [0x00febc4000 - 0x00febc407f] mem 2.425: PCI: 00:12.4 10 <- [0x00febc0000 - 0x00febc0fff] mem 2.426: PCI: 00:13.0 10 <- [0x00febc1000 - 0x00febc1fff] mem 2.428: Done setting resources. 2.429: Done allocating resources. 2.456: Enabling resourcess... 2.456: PCI: 00:00.0 cmd <- 147 2.457: PCI: 00:02.0 cmd <- 143 2.460: PCI: 00:12.0 cmd <- 14f 2.461: PNP: 002e.4 missing enable_resources 2.462: PCI: 00:12.2 missing enable_resources 2.467: PCI: 00:12.1 cmd <- 142 2.467: PCI: 00:12.2 cmd <- 141 2.468: PCI: 00:12.3 cmd <- 142 2.473: PCI: 00:12.4 cmd <- 142 2.474: PCI: 00:13.0 cmd <- 142 2.474: done. 2.475: Initializing devices... 2.478: Root Device init 2.478: PCI: 00:00.0 init 2.479: northbridge: northbridge_init() 2.480: PCI: 00:12.0 init 2.480: PNP: 002e.0 init 2.488: PNP: 002e.1 init 2.489: PNP: 002e.2 init 2.489: PNP: 002e.5 init 2.489: PNP: 002e.6 init 2.490: PNP: 002e.7 init 2.490: PCI: 00:02.0 init 2.491: PCI: 00:12.1 init 2.498: PCI: 00:12.2 init 2.504: PCI: 00:12.3 init 2.504: PCI: 00:12.4 init 2.510: PCI: 00:13.0 init 2.511: Devices initialized 2.512: Copying IRQ routing tables to 0xf0000...done. 2.513: Verifing copy of IRQ routing tables at 0xf0000...failed 2.514: Moving GDT to 0x500...ok 2.527: Wrote linuxbios table at: 00000530 - 000006bc checksum 91c5 2.527: 2.528: Welcome to elfboot, the open sourced starter. .... ----- I attached the Config.lb that I created for this board.It was adapted from the eaglelion/5bcm.

[LinuxBIOS] Chipset options for dual core Pentium D
by Justin C. Darby 07 Dec '05

07 Dec '05

Hi Folks, I'm working on pricing out an embedded system board for a PBX application. Two of the manufacturers I have contacted, regarding pricing and preformance requirements, have suggested using a dual core pentium platform. The target is going to boot from an integrated IDE compact flash target, which should be pretty easy using LinuxBIOS, however.. Is there any chipset support present in LinuxBIOS that covers the Pentium D dual core solution? Since I have direct control over the design, it'd be easier to stick to what's known to work. Thanks, Justin

BIOS Looks like old UV-eraseable ROM: under an "Eagles" sticker there is something like a circle-shaped window. Actually, the main trouble with current BIOS is that it can count all the 128M of DIMM installed, but reports to Linux kernel (2.6.8) only the first 64M. Playing with mem="640K@0M 127M@1M" (or other variations does not help: kernel hangs at boot saying "Loading kernel"). memtest86+'s probe reports those 128M and tests run fine. Soryy for the off-topic. With the best regards, Andrey.

This applies for most other boards in the latest tree. We'll gladly assist you if you are going to test this. As an option you can always choose a snapshot from 1.5 months ago. Stefan

[LinuxBIOS] Via MB suggestion
by Richard Smith 05 Dec '05

05 Dec '05

Hey all you via dudes: I'm looking at using one of these small ITX or mini-ITX boards for a personal project. And of course I want it to boot LinuxBIOS. I'm going to need LCD output to a >= 800x600 screen and X allthough I could probally make it work with the framebuffer as well. I don't need a lot of power just enough to run a pyQT3 python app play mp3's. What some MB board names I should I start looking for? There's loads of options. Which ones so far are known to boot? Which ones are bios hacker friendly? (Meaning it has a PLCC or DIP flash rather than TSOP) -- Richard A. Smith

[LinuxBIOS] Save the trees!
by Stefan Reinauer 04 Dec '05

04 Dec '05

Hi, after the LinuxBIOS tree was in a quasi permanent state of adaption during the last two months, it is getting to a state where we need heavy testing and reporting from users out there. Ron, Ollie, Yinghai and me have been trying to do some heavy fixing to get things going again, and the result can be seen here: http://snapshots.linuxbios.org/stats/abuild-LinuxBIOSv2-2131.log Now no more than three (3!) mainboards fail compilation: agami/aruma intel/xe7501devkit momentum/apache The next step should be to switch more mainboards over to cache as ram (especially the agami/aruma, which fails due to lack of registers in romcc) and, again, to test the current tree. Please go ahead and try any supported systems you have access to and send reports to this list, or to me. Best regards, Stefan
