[LinuxBIOS] serial port on GRUB
by Robert Millan 10 Nov '07

10 Nov '07

Hi With this commit serial port should work on GRUB now. Please can someone test on real hardware and confirm ? (note: you need to initialise it with `serial' command, then switch to it with `terminal serial') 2007-11-10 Robert Millan <rmh(a)aybabtu.com> * include/grub/i386/efi/machine.h: New file. * include/grub/i386/linuxbios/machine.h: Likewise. * include/grub/i386/pc/machine.h: Likewise. * include/grub/powerpc/ieee1275/machine.h: Likewise. * include/grub/sparc64/ieee1275/machine.h: Likewise. * term/i386/pc/serial.c: Include <grub/machine/machine.h>. (serial_hw_io_addr): New variable. (serial_hw_get_port): Obtain port address from `serial_hw_io_addr' instead of `(unsigned short *) 0x400'. -- Robert Millan <GPLv2> I know my rights; I want my phone call! <DRM> What use is a phone call, if you are unable to speak?

[LinuxBIOS] [PATCH] Common code base for Advantech PCM-5820, ASI MB_5BLMP, BCOM WinNET100
by Uwe Hermann 10 Nov '07

10 Nov '07

Hi, here's a first patch (in a row of a bunch of other, similar planned patches) which reduces the amount of crappy, duplicated mainboard code in the repository. (it also adds support for a new target, the Advantech PCM-5820, btw.) This common code supports three different GX1-boards, more will follow. We have at least 7 of them in the repo right now (and I'll add more), duplicating the same crap in each mainboard/* directory again and again is definately not what we want to do. This is build-tested, and runtime-tested on hardware on two boards. Erwan Velu <erwan(a)seanodes.com> will likely be able to test on the Advantech PCM-5820 soon. I'm planning similar patches for unifying the code for CK804 based boards, and others. E.g. we can easily support the - ASUS A8NE-FM/S - ASUS A8N-E - ASUS A85NX - and probably lots more very similar boards from one common code base (and we should!). Note: I'm not saying that we _must_ do this with _all_ boards in the repository. If the differences are too big, this doesn't make too much sense. But I have a very strong opinion that we should indeed do it for all boards which are reasonably similar. The savings even in this (GX1) case are pretty large, but if you look at some CK804/MCP55 boards, you'll see that it makes a _dramatic_ difference in the amount of code whether you copy-paste or use a generic common code base. Comments welcome, Uwe. -- http://www.hermann-uwe.de | http://www.holsham-traders.de http://www.crazy-hacks.org | http://www.unmaintained-free-software.org

[LinuxBIOS] [PATCH] v2: Add a bunch of Intel 440BX boards
by Uwe Hermann 10 Nov '07

10 Nov '07

Hi, here's a number of patches which add (or fix) quite a bunch of Intel 440BX / 82371EB based boards. As per recent discussion I have reluctantly abandoned the idea to have a common code base for all of them (and I'm not really happy with this). Rest assured that they _will_ be merged into a common code base when ported to v3, though. Except for very, very few lines per board, they're all identical. The Options.lb files are _fully_ identical for all of them, not a single byte differs. I might post a followup patch to fix that at least. I'll follow-up on this mail with the patches, one per board. Thanks to various people on IRC for helping out with information and testing of some of these boards: - todthgie: Compaq Deskpro EN SFF P600. - idwer_: ASUS P2B. - zxy_64-2: AZZA PT-6IBD. (and maybe other which I might have forgotten; sorry) The rest of the boards are mine, not _all_ of them are tested on hardware yet (but most are). Every board in the patch series is build-tested. Note that this doesn't mean all of them are _fully_ supported yet. Some might need smaller adaptions, all of them are crippled a bit by the currently incomplete 440BX and 82371EB support (I have patches for both, which I'll post soon). I'm relatively sure that all of them should boot up to a Linux login prompt already, though. A more detailed status report will follow in the next few days in the resp. wiki Status/Tutorial pages. Uwe. -- http://www.hermann-uwe.de | http://www.holsham-traders.de http://www.crazy-hacks.org | http://www.unmaintained-free-software.org

Re: [LinuxBIOS] Which svn revision works with VIA EPIA M-II?

I forgot a couple of things: > > option ROM_SIZE=256*1024 You need something like this: option ROM_SIZE=256*1024-64*1024 # This assumes a 64K video BIOS > The reason that they're different is that 12*65536 != 790528 > > You should check the first few bytes of a video ROM to look for the > signature (AA55) Use hexdump | head or view it in a hex editor. > > You can also use strings. The ROMs I've seen have some recognizable > strings in them. Note that this needs to be coupled with looking for the signature to make sure that you're starting in the right place. Hopefully when you build you'll have a (256-64)*1024 = 192K image that you can prepend your 64K Video BIOS to. Myles

Hi guys, I finally have spare ROM chips to play with and I am ready to put LinuxBIOS on them - I have problems with compiling the beast, however. I have checkied out the latest revision from SVN and here's what I'm getting when trying to compile: --------------- CUT -------------------- gcc -m32 -nostdlib -nostartfiles -static -o linuxbios_ram -T /home/luke/src/carpc-project/LinuxBIOSv2/src/config/linuxbios_ram.ld linuxbios_ram.o nm -n linuxbios_ram | sort > linuxbios_ram.map objcopy --gap-fill 0xff -O binary linuxbios_ram linuxbios_ram.bin gcc -O2 -DENCODE -DDECODE -DMAIN -DVERBOSE -DNDEBUG -DBITSIZE=32 -DENDIAN=0 /home/luke/src/carpc-project/LinuxBIOSv2/util/nrv2b/nrv2b.c -o nrv2b ./nrv2b e linuxbios_ram.bin linuxbios_ram.nrv2b input/output = 64748/29627 = 2.185 cp linuxbios_ram.nrv2b linuxbios_ram.rom echo '/*ldoptions*/' > ldscript.ld; cat ldoptions >> ldscript.ld ; for file in /home/luke/src/carpc-project/LinuxBIOSv2/src/arch/i386/init/ldscript_fallback.lb /home/luke/src/carpc-project/LinuxBIOSv2/src//cpu/x86/16bit/entry16.lds /home/luke/src/carpc-project/LinuxBIOSv2/src//cpu/x86/32bit/entry32.lds /home/luke/src/carpc-project/LinuxBIOSv2/src//cpu/x86/16bit/reset16.lds /home/luke/src/carpc-project/LinuxBIOSv2/src//arch/i386/lib/id.lds /home/luke/src/carpc-project/LinuxBIOSv2/src//arch/i386/lib/failover.lds ; do echo /\* $file \*/ >> ldscript.ld; cat $file >> ldscript.ld ; done gcc -m32 -nostdlib -nostartfiles -static -o linuxbios -T ldscript.ld crt0.o /usr/bin/ld: warning: dot moved backwards before `.reset' /usr/bin/ld: warning: dot moved backwards before `.id' /usr/bin/ld: warning: dot moved backwards before `.id' /usr/bin/ld: warning: dot moved backwards before `.id' /usr/bin/ld: section .id [00000000ffffffd9 -> 00000000ffffffef] overlaps section .rom [00000000ffffb3bf -> 000000010000192f] /usr/bin/ld: linuxbios: section .id lma 0xffffffd9 overlaps previous sections collect2: ld returned 1 exit status make[1]: *** [linuxbios] Error 1 make[1]: Leaving directory `/home/luke/src/carpc-project/LinuxBIOSv2/targets/via/epia-m/epia-m/fallback' make: *** [fallback/linuxbios.rom] Error 1 --------------- CUT -------------------- Here's my Config.lb: --------------- CUT -------------------- # Sample config file for EPIA-M # This will make a target directory of ./epia-m target epia-m mainboard via/epia-m option MAXIMUM_CONSOLE_LOGLEVEL=8 option DEFAULT_CONSOLE_LOGLEVEL=8 option CONFIG_CONSOLE_SERIAL8250=1 option ROM_SIZE=256*1024 option HAVE_OPTION_TABLE=1 option CONFIG_ROM_PAYLOAD=1 option HAVE_FALLBACK_BOOT=1 ### ### Compute the location and size of where this firmware image ### (linuxBIOS plus bootloader) will live in the boot rom chip. ### option FALLBACK_SIZE=0x18000 ## LinuxBIOS C code runs at this location in RAM option _RAMBASE=0x00004000 ### ### Compute the start location and size size of ### The linuxBIOS bootloader. ### # # EPIA-M # romimage "normal" option USE_FALLBACK_IMAGE=0 option ROM_IMAGE_SIZE=0xc000 option ROM_SECTION_OFFSET=0x10000 option ROM_SECTION_SIZE=0x18000 option LINUXBIOS_EXTRA_VERSION=".0-Normal" payload $(HOME)/src/carpc-project/filo-0.5/filo.elf end romimage "fallback" option USE_FALLBACK_IMAGE=1 option ROM_IMAGE_SIZE=0xc000 option LINUXBIOS_EXTRA_VERSION=".0-Fallback" payload $(HOME)/src/carpc-project/filo-0.5/filo.elf end #buildrom ./linuxbios.rom ROM_SIZE "normal" "fallback" buildrom ./linuxbios.rom ROM_SIZE "fallback" --------------- CUT -------------------- I have commented out the normal build because I want to prepend original VGA BIOS from the board to LinuxBIOS and I guess the fallback one is the right one to use (at least according to LinuxBIOS documentation (documentation/HOWTO/EPIA-M-howto). This file also states how to get the VGA bios: dd if=/dev/mem of=/video.bios.bin \ bs=1 count=65536 skip=790528 while Confirmed working SVN revisions at http://www.linuxbios.org/index.php/Confirmed_working_svn_revisions says something different: dd if=/dev/mem of=video.bios.bin.4 bs=65536 count=1 skip=12 (I have checked that generated files differ) Big thanks, -- Coquelicot
