Re: configurable HT speeds.

With normal BIOS, there is option to let End user to select 1000Mhz or 800Hz. And customer report there is performance difference with that.

SMP linux
by Gin 18 Jan '05

18 Jan '05

I've been stuck at this problem for a while. My linuxbios boots a NON-SMP kernel ok but not the SMP one. The SMP kernel gets loaded and run. When it tries to access an IDE drive, an IDE command timed out before anything returns(kernel messages). My I/O APIC settings correspond to the MP table. All ISA devices are mapped to the I/O IOAPIC at 0xFEC00000. But where do we set this I/O APIC up? How does it know to route the IRQs to the local APIC? Another question is, does linuxbios setup the local APIC as Virtual Wire mode that via I/O APIC? My board is similar to Tyan/s2735, does anyone get this booted with a SMP linux before?? many thinks, gin

configurable HT speeds.
by Stefan Reinauer 18 Jan '05

18 Jan '05

Hi, as far as I see CPU-CPU HT links are configured with 800MHz at max. C0 and newer K8 CPUs should be able to do 1000. Is there any reason not to enable this in such case? Also, if there happened to be 8131 which do 800MHz on the link, can we make this configurable via cmos or is Config.lb the way to go that early? Stefan

Yes. I swap the class_hi and class_lo in pci_rom.h YH -----Original Message----- From: Li-Ta Lo [mailto:ollie@lanl.gov] Sent: Tuesday, January 18, 2005 10:31 AM To: YhLu Cc: Eric W.

I want to execute one option rom for onboard device, and work out to find one bug about class code. Another problem is that some option rom has wrong class code....I wonder if device id and vendor id is enough... YH

Maybe need to check the CPU rev to find out the errata to be applied to limit the speed to 800Mz. That would be easy.

v2 testbios compile error
by Richard Smith 18 Jan '05

18 Jan '05

I'm trying to compile the userspace standalone version of testbios and I'm getting errors in all of the pciReadByte, Word and Long functions. 'too many arguments to function pci_get_dev' Anyone else have this issue? V1 testbios on the same machine compiles fine. -- Richard A. Smith
