Re: [LinuxBIOS] Build broken?

OK, Let me explain that again: Final LinuxBIOS image = VGABIOS ROM + Normal Image + FallBack Image FallBack Image = PayLoad + linuxbios_ram.n2v + linuxbios_rom Linuxbios_rom = crt0.S + init.o + id + reset_vector Reset_vector is sit on 0xfffffff0, and at the very beginning, reset happen, the ROM only can be accessed in 64K range. So need to make sure _start in crt0.S need to stay in last 64 address range. The init.o will include cache_as_ram_auto.c in the fallback amd64_main, it will enabled the access 4M flash access. When We were using ROMCC, the crt0.S will be very bigger (it include auto.inc), So for 8 way or 4 way system, It will push out the _start out of last 64K. When We are using CAR, the init.o is all the same size for 8way and 2 way system. ( because CAR use gcc, and have real stack for functional call, ROMCC can not have stack because of limited regs) Another problem is if put set ROM_IMAGE_SIZE too big, the current lds can not curbe crt0.S to stay in last 64K too... So you need to set your ROM_IMAGE_SIZE carefully for FALLBACK image. If it is too small, it could not fit Payload +linuxbios_ram.n2v+linuxbios.rom It it is too big, _start in crt0.S will out of last 64K.... Later we could modify .lds to force crt0.S and init.o stay in last 64K.... Or change Linuxbios_rom = init.o + crt0.S + id + reset_vector.... ( need make sure enable_rom in 64K too...) But is not high priority, because crt0.S+init.o for CAR are always small.... Other problem is you must use Linux otherthan Redhat and Suse???? And you need to upgrade your gcc YH -----Original Message----- From: beneo [mailto:beneo@comcast.net] Sent: Thursday, November 10, 2005 11:54 AM To: Lu, Yinghai; Ronald G Minnich Cc: linuxbios(a)openbios.org Subject: Re: [LinuxBIOS] Build broken? Thanks. It works on one of issues I have encountered. My immidiate question is why my ROM_IMAGE_SIZE with larger value 0x20000 won't work, but with 0x16380 would work? If you don't tell me this, I probably would never be able to figure out. My have another issue, It looks like a bug in target tyan/s2891. I'm trying to build tyan/s2891. No matter what I change, I always get a build error like: --- gcc -m32 -nostdlib -nostartfiles -static -o linuxbios -T ldscript.ld crt0.o init.o /usr/bin/ld: section .rodata.str1.32 [fffbff80 -> fffc0091] overlaps section .reset [fffbfff0 -> fffbffff] collect2: ld returned 1 exit status make[1]: *** [linuxbios] Error 1 --- Then I looked at ldscript file, it included southbridge/nvidia/ck804/id.lds file, which looks like this: --- SECTIONS { . = (_ROMBASE + ROM_IMAGE_SIZE - 0x80) - (__id_end - __id_start); .id (.): { *(.id) } } --- There is no linker script would arrange section .rodata.str1.32. I guess that just makes linker to patch section .rodata.str1.32 at end of .id section, which caused the overlap with .reset section. This looks to me is a bug in tyan/s2891. How do I fix this? is that OK to remove nvidia/ck804/id.lds? thanks beneo ----- Original Message ----- From: "Lu, Yinghai" <yinghai.lu(a)AMD.COM> To: "beneo" <beneo(a)comcast.net>; "Ronald G Minnich" <rminnich(a)lanl.gov> Cc: <linuxbios(a)openbios.org> Sent: Wednesday, November 09, 2005 7:39 PM Subject: Re: [LinuxBIOS] Build broken? > Please change ROM_IMAGE_SIZE in romimage "fallback" section to 0x16380 > > YH > > > > -- > LinuxBIOS mailing list > LinuxBIOS(a)openbios.org > http://www.openbios.org/mailman/listinfo/linuxbios

At the same time, you could set FALLBACK_SIZE to 256K, in case you have a big FILO in etherboot with USB support. YH

With attach lds, the linuxbios_rom will be fixed on 0x0xffff0000 for fallback image. Anyway address is fixed, leave last 64k for crt0.s and init.o now.... YH

[LinuxBIOS] Tyan S2850 VGA
by Jun OKAJIMA 11 Nov '05

11 Nov '05

Hello. I am looking for M/B with these specs. 1. Boots fast (2 or 3 secs) with linuxbios ( or other utils). 2. Supports VGA, including X. 3. High performance. Like over 2GHz or such. How about S2850? it suppors VGA with X? Or, you know any other M/B? --- Okajima

[LinuxBIOS] Fast booting
by Jun OKAJIMA 10 Nov '05

Do you know any other fast boot solution than linuxbios? I tested Via fast boot util, but it is not so fast... For example, how about this. General Software Embedded BIOS http://www.gensw.com/pages/prod/firmbase/firmbase.htm --- Okajima, Jun. Tokyo, Japan.

[LinuxBIOS] VIA EPIA M10000 (Nehemiah) CentaurHauls Stepping 5 support status
by tristan 10 Nov '05

10 Nov '05

Hi list, I'd like to know the exact support status of LinuxBIOS on VIA EPIA M10000 (Nehemiah) CentaurHauls Stepping 5. I've seen messages (August 2005) that say VGA is supported, and more recent threads that say it isn't. So, what is supported by the mainstream LinuxBios v2 ? And what is not yet? Are these any patches around that could achieve better support? All different messages I see are rather confusing ... Another question: VIA has published a "FastBoot" BIOS that seems to be a fork of LinuxBIOS, since it's a fork and LinuxBIOS is covered by GPL, is FastBoot a GPL violation? Someone has ever had the sources of FastBoot? If ever, could it lead to a better support of EPIA motherboards? Thanks for you answers, Tristan

[LinuxBIOS] Build broken?

Hi, I download a lateset snapshot from linuxBIOS.org yesterday. I don't know if it is bad luck or something, I can not successfully build any BIOS from the tree I downloaded. I tried following three platform. tyan/s2891 tyan/s2895 amd/serenade Does anybody has similar issue or know what happened? Below are the details on the things I got for these three different target platform 1. Both tyan/s2891 and tyan/s2895 have similar behavior I changed a few lines in Options.lb: default USE_DCACHE_RAM=1 default CONFIG_USE_INIT=1 default DEFAULT_CONSOLE_LOGLEVEL=7 default MAXIMUM_CONSOLE_LOGLEVEL=7 I get a error output like below: (Note: Changing options in the Options.lb above were not the cuase of the problem. Without changing USE_DCACHE_RAM and CONFIG_USE_INIT, I still get same results) ------------ gcc -m32 -nostdlib -nostartfiles -static -o linuxbios_ram -T /export/1/new/src/config/linuxbios_ram.ld linuxbios_ram.o linuxbios_ram.o(.text+0x13db9): In function `smp_write_config_table': : undefined reference to `get_apicid_base' collect2: ld returned 1 exit status make[1]: *** [linuxbios_ram] Error 1 make[1]: Leaving directory `/export/1/new/targets/tyan/s2895/s2895/normal' make: *** [normal/linuxbios.rom] Error 1 2. amd/serenade gets the build error like below. It probably is the side product of the tree enabled dual core and cache as RAM? ----- gcc -m32 -nostdlib -nostartfiles -static -o linuxbios_ram -T /export/1/new/src/config/linuxbios_ram.ld linuxbios_ram.o linuxbios_ram.o(.text+0x14d2): In function `model_fxx_init': : undefined reference to `get_node_core_id' linuxbios_ram.o(.text+0x14e6): In function `model_fxx_init': : undefined reference to `amd_sibling_init' collect2: ld returned 1 exit status make[1]: *** [linuxbios_ram] Error 1 make[1]: Leaving directory `/export/1/new/targets/amd/serenade/serenade/normal' make: *** [normal/linuxbios.rom] Error 1 Any help would be appriciated.

Where do I find information on booting "tiny kernel"? Or could you guys explain it to me? Thanks, Matt

Re: [LinuxBIOS] [Etherboot-developers] Infiniband driver
by Lu, Yinghai 09 Nov '05

Who want it? LinuxBIOS, current System BIOS or EFI? For LinuxBIOS, We will use LinuxBIOS+tiny kernel for booting. The Tiny kernel could include IB and IP over IB, So we don't need to port driver from kernel to everywhere....

In our plans is a to add support for a second line of devices. This will allow a host having an HCA to use it for doing remote boot. It is based on Etherboot and we would like to open the source to the public and we would like it to be part of Etherboot. I would like to know how to move in this direction.
