mptable and redhat 8 and wotta mess.
by Ronald G. Minnich Dec. 3, 2002

If I build linuxbios with gcc 2.96, things get marginally better. But weirder. Linux version 2.4.19-lanl.18beoboot (root@butthead) (gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-112)) #1 Fri Aug 16 15:03:04 MDT 2002 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 0000000000000bd0 (reserved) BIOS-e820: 0000000000000bd0 - 00000000000a0000 (usable) BIOS-e820: 00000000000f0000 - 00000000000f0400 (reserved) BIOS-e820: 0000000000100000 - 0000000020000000 (usable) BIOS-e820: 0000000100000000 - 0000000120000000 (usable) Warning only 896MB will be used. Use a PAE enabled kernel. 896MB LOWMEM available. hm, page 00000000 reserved twice. On node 0 totalpages: 229376 note that it is still not seeing the MP table. But later on: PCI: Discovered primary peer bus 10 [IRQ] PCI: Discovered primary peer bus 11 [IRQ] PCI: Discovered primary peer bus 12 [IRQ] PCI: Using IRQ router PIIX [8086/2480] at 00:1f.0 PCI: Found IRQ 11 for device 00:1d.0 PCI: Sharing IRQ 11 with 07:01.0 PCI: Found IRQ 5 for device 00:1f.1 PCI: Found IRQ 3 for device 00:1f.3 PCI: Found IRQ 7 for device 02:01.0 So how is it getting this info? I am now getting confused. nevertheless it does get the new kernel fine over the myrinet. The ram map still looks like this: BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 0000000000000bd0 (reserved) BIOS-e820: 0000000000000bd0 - 00000000000a0000 (usable) BIOS-e820: 00000000000f0000 - 00000000000f0400 (reserved) BIOS-e820: 0000000000100000 - 0000000020000000 (usable) BIOS-e820: 0000000100000000 - 0000000120000000 (usable) Note also that the RAM map shows (for this newer linuxbios) a big hole in the ram map. 2.4.19 doesn't seem to be able to handle this, more below: Warning only 4GB will be used. Use a PAE enabled kernel. 3200MB HIGHMEM available. OOPS! There's only 1024 MB but the kernel is doing something odd. Now the older linuxbios (a version from LNXI that says 1.0.0.6) show this for the ram map: BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 0000000000000b54 (reserved) BIOS-e820: 0000000000000b54 - 00000000000a0000 (usable) BIOS-e820: 00000000000f0000 - 00000000000f0400 (reserved) BIOS-e820: 0000000000100000 - 0000000040000000 (usable) 128MB HIGHMEM available. 896MB LOWMEM available. And this works. So, that's the state of play: linuxbios is now producing e820 maps that 2.4.19 doesn't seem to be able to handle; something is somehow trashing the MP table (etherboot); and, in general, things on e7500 are not currently working. More later. ron

mp table and gcc 3.2 and ....
by Ronald G. Minnich Dec. 2, 2002

Dec. 2, 2002

the mp table (_MP_) is also ok. Now this is getting weird. All the data in all the tables looks fine, almost byte-for-byte the same (I'm still working out what's different). But Linux never finds this MP table when loaded from a gcc 3.2-compiled linuxbios. The same linux, booted with linuxbios compiled on gcc 2.96, finds the table no trouble. Any hints anyone :-) how many people are building linux with RH 8.0, and these gcc tools: root@pinkish tmp]# gcc -v -v Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2/specs Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --host=i386-redhat-linux --with-system-zlib --enable-__cxa_atexit Thread model: posix gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7) [root@pinkish tmp]# as -v -v GNU assembler version 2.13.90.0.2 (i386-redhat-linux) using BFD version 2.13.90.0.2 20020802 [root@pinkish tmp]# ld -v -v GNU ld version 2.13.90.0.2 20020802 GNU ld version 2.13.90.0.2 20020802 ron

MP table and gcc 3.2
by Ronald G. Minnich Dec. 2, 2002

Dec. 2, 2002

OK, I've verified that most of the bits are right. The only thing that seems broken is the floating table structure (_MP_), the data in memory for that look quite wrong. The other structs (i.e. PCMP) seem to be ok. I think I've almost got it. ron

linuxbios and gcc 3.2
by Ronald G. Minnich Dec. 2, 2002

Dec. 2, 2002

I'm trying to track down the problems with linuxbios, mptables, and gcc 3.2 The symptom is that the myrinet card which is in the slot for 02:1.0 ends up with IRQ 0 when linux is done parsing the mp table. So far I am dumping the intsrc entries in the mp table and they look fine from the linuxbios side. If anyone has any hints I'll take them. This is weird. ron

motherboard owners: you know who you are:
by Ronald G. Minnich Dec. 1, 2002

Dec. 1, 2002

It would help a lot if those of you who are The Experts on a given motherboard would update your STATUS and send me the patches. Otherwise I'm going to have to guess on some of these (nano, etc.) and I might not get it right. thanks ron

Is a Doc is necessary?

Hi, All: Who can tell me whether a Doc is necessary for linuxbios? Can I burn on a ROM only? Thank, Lawrence

National Semiconductor Geode GX1 ?
by Rob van Nieuwkerk Dec. 1, 2002

Dec. 1, 2002

Hi All, I am using a small (4"x6") SBC board with a NS Geode GX1 and CS5530 for a project. It's a complete PC on a 3.5" formfactor (300 MHz Geode, SODIMM, floppy, IDE, CF, serial, Ethernet, USB, keyboard, mouse, Video, LCD, PC/104). See: http://www.axiomtek.com/product-info.php?cat=Embedded+PCs&model=SBC84510VEE… And I'm very interested in using linuxbios with this board (or a similar board: there are several manufacturers making small boards like this). I searched the linuxbios mailing-list archives for messages about Geode systems, but I only found references about SC1200 and SC2200 systems. And I did't find info on the Geode GX1 in the linuxbios status list. So my question is: - anybody know something about the possibility of running linuxbios on a NS Geode GX1 ? greetings, Rob van Nieuwkerk
