>Are io-apics limited to apic ids 0x0-0x0f as well? > >My memory says to me the limit should be 0x0-0xff... before enable ext_apic_id, Opteron only can use 4 bit for apic id, So only 16 apic id. After enable ext_apic_id in every opteron, it will use 8 bit for apic id, So we got 256 apic id. Then CPU can use 0x10 above apic id. some io apic device only support 4 bit apic id, So We can leave 0x0-0xf to them. that is for AMD, it is said that intel's from p4 has 256 for default.

I tried to make cache_as_ram_auto.c more smaller, the problem is I can not use jmp __cpu_reset, and I need use goto cpu_reset_x YH -----Original Message----- From: ebiederman(a)lnxi.com [mailto:ebiederman@lnxi.com] Sent: Tuesday, September 06, 2005 1:26 PM To: Lu, Yinghai Cc: Jason Schildt; linuxbios(a)openbios.org Subject: Re: [LinuxBIOS] LNXI Merge: lnxi-patch-15/16 "Lu, Yinghai" <yinghai.lu(a)amd.com> writes: > I think CAR for AMD Opteron MB esp Tyan MBs are validated. > &… [View More]

if you're coming, you had best register. We have fewer registrations than we hoped for ... note that we're going to have a pretty good vendor presence, and also will be describing new developments in linuxbios. thanks ron

[LinuxBIOS] I'm alive..
by windex 07 Sep '05

07 Sep '05

HI folks, Just a quick note that I'm still alive. If I have some time, I'll try to start contributing to the wiki again. I was reminded of what was going on by someone who hunted me down over MSN via my personal site (from my users page). The company I was working for had some financial problems, which led to me being very busy for awhile, then practically doing nothing, then canned for lack of resources. If anyone has any interest in providing some financial support for me to spend time … [View More]

I never tried out by change option use cmos_util to get boot normal to fallback. I mean if I change option in CMOS from fallack to normal. The system will always in normal, until I clear the CMOS.

[LinuxBIOS] mmx problems on VIA EPIA-SP resolved
by Doug Bell 06 Sep '05

06 Sep '05

We are working on VIA EPIA-SP with C3-2 processsor and have resolved problems related to the use of the mmx as seen in the auto.inc. The code was hanging unless we used -mno-mmx in Config.lb. We then modified /src/cpu/via/model_centaur_init.c cpu_table[] to include {X86_VENDOR_CENTAUR, 0698}, // VIA C3 Nehemiah If anyone else is doing work on this board please let us know! Our code isn't far enough along to check in. Some questions remain: 1) Is the C3-2 supported yet? What's needed … [View More]

[LinuxBIOS] LNXI merge: lnxi-patch-00/16
by Jason Schildt 06 Sep '05

06 Sep '05

All, I've taken the ill-fated merge attempt from a few weeks ago and have reworked it into 16 smaller, logical patches. I've also made certain that in the end, when all patches are applied all of the touched boards will build. Each patch I submit will consist of a brief description of what was changed and why, as well as a diffstat and the patch itself. I'll start submitting the diffs for review. --jason-- -- Jason W. Schildt LinuxBIOS Software Engineer Linux Networx
