[LinuxBIOS] Solaris
by Justin Cormack 06 Aug '05

06 Aug '05

Has anyone looked at what it would take to get Solaris booting under Linuxbios on Opteron? If not I might dig around (there is a modified grub - I think that does some of the init work; one suspects that because of its heritage it is quite BIOS-unencumbered). justin

About APIC and ACPI. Some chipset has problems with apic and the workaround must to be used with acpi BIOS. YH

[LinuxBIOS] Local APIC IDs for dual Xeons
by Steve Magnani 30 Jun '05

30 Jun '05

Hi all, I've reached the point where LB is attempting to start the secondary CPU on my custom board. As near as I can tell, LB thinks the secondary CPU isn't responding. This could be a hardware problem, or a LB issue of some sort. CPU 6 would not start! CPU 6 did not initialize! First thing I wanted to check was that LB is using the right APIC ID in the messages it's sending. But I haven't been able to find a good explanation anywhere of how local APIC IDs are assigned in dual-Xeon systems. All Intel says with any certainty is that the power-up sequence includes setting a unique ID for each LAPIC. There is a format to the IDs (i.e. some bits for logical processor, some for socket, some for APIC cluster), but nothing that says (for instance) "One Xeon chip is assigned LAPIC IDs 0 & 1 and the second is assigned LAPIC IDs 6 & 7". Looking over the s2735 config, and anything I found on the Internet, it seems that this is how dual-Xeon boards work. Does anyone know why? Do the addresses come out like this any time you have a dual-Xeon board, and every time you power it up? Or are there some pins that have to be strapped a certain way to end up with these IDs? (Side note, some Xeons support reset-time config of APIC cluster ID - mine don't). The way I'm interpreting the Intel documentation, it looks like the only way to find out a secondary CPU's LAPIC ID is to start it (via an IPI broadcast?) and have it write it somewhere. Thanks, Steve www.digidescorp.com

[LinuxBIOS] Re: floating irq_table
by yhlu 30 Jun '05

just committed the write_pirq_routing_table for s2882 and s2895. for s2882 also move pci_assign_irq from mptable to irq_table.c other x86 irq_table.c all added unsigned long write_pirq_routing_table(unsigned long addr) { return copy_pirq_routing_table(addr); } and table.c will call write_pirq_routing_table instead of copy_pirq_routing_table.

[LinuxBIOS] mianboard Config.lb question....
by Huang-Jen Wang 28 Jun '05

28 Jun '05

Dear all, I am porting a new mainboard, and its chipset are ServerWorks HT1000 and HT2000, in HT1000, it looks like its SMBUS is not a pci device. Because I can find it device number and function number, I have a very serious problem, how do I edit the mainboard Config.lbfile.Dose anyone has the same situation before....or any idea? Thanks

[LinuxBIOS] Abuild test
by Li-Ta Lo 28 Jun '05

28 Jun '05

Hi, I tried to make as many boards to pass abuild test as possible. Now I have most of them working. The non working boards are in three categories: 1. Known to be broken: technologic/ts5300, via/epia-m 2. Bug in ROMCC: island/aruma, ROMCC complain about something in coherent_ht.c:1543.39: coherent_ht.c:1805.27: auto.c:166.47: 0x88cd720 phi Internal compiler error: Cannot find block dominated by 0x83b8150 3. Bug in Abuild: digitallogic/msm586seg, emulation/qemu-i386, Abuild generates incorrect value (0x-5000) for PAYLOAD_SIZE in Makefile.setting. I can figure out why it generate such a insane thing. 4. Bug in ldscript: tyan/s2880, tyan/s4880, the default ROM_IMAGE_SIZE generated by Abuild is wrong for these boards. The value in target Config.lb is good. 5. CAR WIP: tyan/s2735, YhLu, did you ever get CAR working on this one? make[1]: Entering directory `/tmp/freebios2_test/util/abuild/linuxbios- builds/tyan_s2735/normal' make[1]: *** No rule to make target `/tmp/freebios2_test/src/cpu/intel/car/cache_as_ram.inc', needed by `crt0.s'.
