I'm trying to enable the CAR for opteron. 1. create failover.inc and auto.inc with gcc -S 2. change the label in failover.inc from .L --> .fL 3. change section name in failover.inc and auto.c .text --> .rom.text .rodata--> .rom.data .rodata.str...-> .rom.data.str... 4. using following cache_as_ram.inc, and it will be executed after entry.inc at last it will call amd64 in failover.inc or auto.inc 5. current it will die after post code 0x22 I wonder how to make the cpu using the stack in cache.... movl $(CacheBase>>4), %eax movl %eax, %ss is enough?

[LinuxBIOS] TLA Sucks
by Li-Ta Lo 10 Jun '05

10 Jun '05

Ouch, I have messed up the TLA tree many times by trying to commit only the emulator changes. I guess patch-36 to patch-38 are mistakes. I hope I didn't mess the tree too much. BTW, how exactly should I roll back a patch level ? Is the "tla replay --revers" plus "tla sync-tree" the right way to do? Does it undo "tla add"? -- Li-Ta Lo <ollie(a)lanl.gov> Los Alamos National Lab

That's what I said ... it's disabled in the MB Config.lb, but the hardware is still there. It's only two lines in the mptable.c. Do you expect s2895 users to not need the extra 4 SATA ports? Why not fix it? I'm sure you know how to fix it. If I see something that could be improved in the CK804 code, what should I do? So far all my suggestions have been dismissed.

Then maybe the S2895 MB Config.lb shouldn't make it look like the second CK804's SATA devices could be turned on. A comment noting the connector is missing would clear it up. Steve -----Original Message----- but the problem is that S2895 only used SATA on first CK804. And the mptable.c in Mb dir is sth related with MB Configuration. So if you have another MB that enable sata on second ck804, you should create that two entries for sata of it's mptable.c There is no extra space for another four sata connector, also there is some power consumption conern...

Yh Lu wrote: > the sata in second CK804 is disabled in MB Config.lb, So don't need > that. I think that Stephen has already clearly indicated that there is no problem when SATA for the second CK8-04 is disabled. Does the Tyan S2885 hardware (with COTS BIOS) support SATA on the second CK8-04? If so, the mptable should have the entries required to support SATA on the second CK8-04.

The Tyan/s2895 mptable.c is missing two entries for SATA. If the Config.lb file turns the SATA devices on the second CK804, this could be a problem. Ethernet is the only device in the mptable for the second CK804. Steve

Re: [LinuxBIOS] Athlon XP Boards supported linuxbios?
by Ken Fuchs 09 Jun '05

Dirk Ullrich wrote: > Are there any modern boards for Athlon XP supported by linuxbios? No, although it is possible that there might be some in development. However, there is LinuxBIOS support for the Opteron & AMD64 via the AMD-8000 and nForce4 chipsets: The AMD-8000 chipset has excellent support. Many AMD-8000 chipset Tyan boards are very well supported. The nForce4 chipset source code was recently released by Yh Lu from Tyan. This code appears to be stable for nForce4 based Tyan boards. ------ Dirk also asked about nforce2 chipset & Asus A7N8X support: Would it make sense to port the nForce4 code to nForce2/nForce3 and Opteron/AMD64 code to Athlon 32? It seems like a viable option for someone with the time, experience and motivation. Comments? Sincerely, Ken Fuchs <kfuchs(a)winternet.com>
