I'm pretty sure I tried both with -DDCOMPRESERVE (which I understand should make etherboot use the LB settings) and -DCONSPEED=115200 (which is what lb is set to). If you (or anyone else) can confirm you're using 5.4.1 without problems with LB on a serial console then I'll go back and try again, but really I just wanted to know I wasn't spending time debugging something that was known not to work.

Re: [LinuxBIOS] Fwd: [issue50] put pgtbl after 1M
by Lu, Yinghai 12 Dec '05

12 Dec '05

I worked out method 3 too... Please let me know if you want method 3 only or together with method 1. the detail about method 3: copy _secondary_start from 1M above to 1M below and mask the start_eip to 20bit only. It will make _RAMBASE > 0x100000 can work with SMP... BTW, why there are linuxbios(a)openbios.org and linubios(a)linuxbios.org?

Biederman; LinuxBIOS Subject: Re: [LinuxBIOS] Fwd: [issue50] put pgtbl after 1M 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....

The reason is every cpu page table will be 20k, and if there is 16 cpu will need 320k, it will push the stack and heap cross the 0xa0000, the region for vga font buffer. TO use that need to set CONFIG_LB_MEM_TOPK in MB Options.lb It also remove the hardcode 1M in clear_1m_ram.c to use CONFIG_LB_MEM_TOPK.

[LinuxBIOS] I just closed issue 28
by Ronald G Minnich 12 Dec '05

12 Dec '05

patch 04 was superseded by patch 6, but in any event, none of the patches took (they were assumed to be -r). Also, the other epia-m item (29) is in the tree, so I closed that. please, folks, if you are resolving these issues, set the status to resolved and sign it off in comments. Here is the rough path for using this tracker (we're still waiting on the doc) login to the issue tracker. create the issue describe the problem upload the file (x.diff) assign to somebody. somebody else should close the issue, so: - get somebody to review. - annoy us if we don't. to close - if it is global impact, scan carefully. take your time - if it is only one mobo, one person, the person who sent the diff, scan carefully but try to get it done soon. - apply the diff, if it succeeds commit and mark the issue resolved, with 'signed-off-by' in the remarks - if it fails mark it deferred and notify the submitter I am going to try nick barker's patch. It seems somebody is applying these and not following up? ron

Oh yeah. These links have been created so people can add tutorials easily if they build LinuxBIOS for one of these boards. Unfortunately nobody has done so, yet.

[LinuxBIOS] MSI MB support
by Fredrik Tolf 09 Dec '05

09 Dec '05

Hi List! I've been following LinuxBIOS for a while, but unfortunately, I haven't been able to use it, since my motherboard isn't supported. My MB is manufactured by MSI (it's a KT6 Delta), and I've been in e-mail conversation with them about this issue, but let's just say that they have been less than forthcoming about it. :-/ So I guess what I want to ask is what I can do about the situation. Is there any point in trying to just get the chipset specs from VIA (it's a KT600 NB and a VT8237 SB), or are there things that need to be done specifically for the motherboard so that the chipset specs are useless by themselves, apart from the flash memory (which isn't supported either)? I'm more than willing to do the porting work myself, but I'd like to know where I could start, and if it's at all possible without the MB specs. Fredrik Tolf

If so, we ran LinuxBios during initial bring-up of this board, and I believe we contributed back the changes we needed for it. -- greg
