OK, I get it. Thanks. Memtest86 reports errors at memory address 1MB, 5MB, 9MB, 13MB, 17MB, ... not sure what's wrong. //I think Corey got things going on the CN700, are you working from //his patch? yes, I used corey's cn700 patch, and after changed some values I can run ram_check successfully, but as you have said, it's not quite useful... corey's original patch couldn't pass ram_check, and I have no idea why.

[LinuxBIOS] [BUILDROM] Add support for the Cheetah FAM10 target to buildrom
by Jordan Crouse 20 Dec '07

Hey all - following on Marc's awesome Barcelona patches, here is the code to add the fam10 target to buildrom. You may see a stack protect problem, patches following shortly to deal with that. Jordan -- Jordan Crouse Systems Software Development Engineer Advanced Micro Devices, Inc. [BUILDROM] Add support for the Cheetah FAM10 target to buildrom This adds support for the Cheetah FAM10 target in LinuxBIOS to buildrom. Simple port, uses most of the existing S-C infrastructure.

[LinuxBIOS] VGA Support on AMD DB800
by Omar Esteves Duarte Filho 20 Dec '07

20 Dec '07

Hello! I'm trying to use LinuxBIOS with AMD Geode DB800 platform. However, until now, I could not manage to get VGA output working. Here is a summary of what i've tried: - built a LinuxBIOS rom image without VGA support. - downloaded a brand new kernel from www.kernel.org (kernel version: 2.6.23.9). - configured this kernel, enabling these options: [*] AMD Geode family framebuffer support (EXPERIMENTAL) <*> AMD Geode LX framebuffer support (EXPERIMENTAL) - editted GRUB's menu.lst file to include the following entry: title Ubuntu, kernel 2.6.23.9-geodelx-fb root (hd0,1) kernel /boot/vmlinuz-2.6.23.9-geodelx-fb root=UUID=b40ebb15-49bd-4042-ab40-5437c0caa1ba ro quiet splash pnpbios=off initrd /boot/initrd.img-2.6.23.9-geodelx-fb quiet savedefault - compiled fbcon as a module. However, if I try to modprobe fbcon, i get nothing. Running startx also gives me no result... Does anyone have any idea or clue about this? Thanks!

You need to install the Geode framebuffer driver for console graphics and the X driver for X support on your Geode Linux image. Until the driver loads there is only have serial console output.

Every one can help me for reuse this motherboard ? Tnx (Grazie)

[LinuxBIOS] Possible stack protect solutions
by Jordan Crouse 20 Dec '07

20 Dec '07

I need a community vote. There is an lingering stack protect issue in LinuxBIOS, and it hits us when we port new platforms. The problem is that not all of the lines in the various Config.lb files that compile code also include the $(CPU_OPT) variable that we use to pass in the -fno-stack-protector from buildrom. So I offer these two possible solutions. One is a patch to buildrom that changes how we pass in the -fno-stack-protect flag (thanks to Marc for the patch). The other is a patch to LinuxBIOS itself to fix the actual problem and pass $(CPU_OPT) where appropriate in the mainboard Config.lb files. So I leave it to the community - which solution do we prefer? One one hand, the buildrom solution only affects targets when built by buildrom, so abuild and other tools aren't affected, though it glosses over the real problem. On the other hand, any tools who may find CPU_OPT useful for their own uses will hit this too, but it is far more likely to break things. Thoughts? -- Jordan Crouse Systems Software Development Engineer Advanced Micro Devices, Inc. Another possible solution for the stackprotect problem - fixing the problem at its source.

[LinuxBIOS] patch to lib/lar.c and include/lar.h
by ron minnich 20 Dec '07

20 Dec '07

These changes are needed to allow initram to chain to subsequent stage1 phases, per the earlier discussion. The chaining is needed since initram is going to call disable_car, which may, among other things, move the stack around or even lose the contents of stack. Support a return from disable_car is a very difficult proposition. The intent is that I can do this: ret = execute_in_place(&archive, "normal/initram/segment0", main_ram_working); or similar and thus chain from initram to the second part of main, with a new stack and working dram. ron

[LinuxBIOS] VIA EPIA MII 10k stability questions
by Lars Randers 20 Dec '07

20 Dec '07

Hello list! I've been dabbling with this board and the writeups for about a week to little avail, so I'd like to hear from anyone who have this board running stable with LB, and preferably with VGA enabled. I can't seem to build the bios successfully with the Config.vga.filo.lb configs. I have also been investigating spurrious interrupts with the CF slot when running Linux (Centos 4.5 - 2.6.9 kernel) and the strange LAN lockup, which seems to be related to a DMA issue in the southbridge chip. VIA was working with the viaarena foums for a brief period in 2005, but the issue never seemed to be solved and VIA stopped talking on the forum. Should I just trash the board and look for a more stable platform? It's a nice platform, low power and all, but if it's hopelessly flawed in design it's out. Any input on the issue welcome! Furthermore I'm struggeling to get the Linux kernel to boot through the initrd without ending up in a panic. I know it's not a LB issue, but as I said, I'd like to get in contact with anyone who has any knowledge into the problem. The wiki is incomplete in this respect and I certainly wouldn't mind donating some of my time in return updating it if I could get it working. Lars

[LinuxBIOS] problem about dram init
by aaron lwe 20 Dec '07

20 Dec '07

Dear All, I've configured the via cn700 dram controller, and when I did ram_check to many regions(not all, 'cause it wastes time) everything was ok. but after the second stage code finished running, filo failed to be started, with the following errors: ... ... Jumping to boot code at 0x10e5ec entry = 0x0010e5ec lb_start = 0x00004000 lb_size = 0x0001a000 adjust = 0x1bfe2000 buffer = 0x1bfcc000 elf_boot_notes = 0x00015760 adjusted_boot_notes = 0x1bff7760 Unexpected Exception: 6 @ 10:1bfee821 - Halting Code: 0 eflags: 00010006 eax: 1bfee821 ebx: 1bfe2000 ecx: 00000000 edx: 0001a000 edi: 1c000000 esi: 0001e000 ebp: 00019eec esp: 1bffbea0 the lb_mem is : dumping lb_mem resources entry : 0, start 0x0, size 0x1000, type 0x10 entry : 1, start 0x1000, size 0x9f000, type 0x1 entry : 2, start 0xc0000, size 0x30000, type 0x1 entry : 3, start 0xf0000, size 0x10000, type 0x10 entry : 4, start 0x100000, size 0x1bf00000, type 0x1 and the mtrr is : Setting variable MTRR 0, base: 0MB, range: 256MB, type WB ADDRESS_MASK_HIGH=0xf Setting variable MTRR 1, base: 256MB, range: 128MB, type WB ADDRESS_MASK_HIGH=0xf Setting variable MTRR 2, base: 384MB, range: 64MB, type WB the total memory I reported to system through ram_resource in pci_domain_set_resource was tolmk(which is 512 * 1024) - 64 * 1024 the 64MB is for the integrated graphics card's framebuffer. When I accidentally reduce the system memory in ram_resource to tolmk - 2 * 64 * 1024, filo could be started, but linux kernel failed to be started. I then used memtest to do the test, and memtest displayed many errors, including the regions I ram_checked ok. could anybody give me any hints? can I say ram is initialized right? Thanks.
