Resident SIS expert
by Frank 23 Mar '04

23 Mar '04

I'm trying to figure out how to reroute i/o amd memory space from the pci space to the LBC Bridge. Anyone out there know which registers to touch in the SSI550. I have the SIS register programming but it doesn't describe which registers have to be touched to accomplish this. __________________________________ Do you Yahoo!? Yahoo!

All K8 builds now broken
by ron minnich 23 Mar '04

23 Mar '04

Sorry. Greg just found that nobody nowhere was setting a few crucial variables, like k8. He is tracking down the missing settings. You can too if you wish. It's amazing how a simple problem has uncovered such a den of snakes, but that's the way it goes sometimes. ron

two changes to make building EPIA work
by ron minnich 22 Mar '04

22 Mar '04

First, src/include/cpu/cpufixup.h is changed to follow the common linuxbios usage. #if CPU_FIXUP == 1 # if (k8==1) #warning "====>Temporary notice that we are using k8 cpufixup" # define cpufixup(mem) k8_cpufixup(mem) # elif (k7==1) #warning "====>Temporary notice that we are using k7 cpufixup" # define cpufixup(mem) k7_cpufixup(mem) # elif (i786==1) #warning "====>Temporary notice that we are using i786 cpufixup" # define cpufixup(mem) i786_cpufixup(mem) # elif (i686==1) #warning "====>Temporary notice that we are using i686 cpufixup" # define cpufixup(mem) p6_cpufixup(mem) # endif #else #warning "====>YOU DID NOT DEFINE ONE OF: k8, k7, i786, i686" # define cpufixup(mem) do {} while(0) #endif note that it is compare to 1, not just an #ifdef. We are leaving the warning in for a while to make sure people see this. In the EPIA, the symbol k8 even if defined to 1 would end up needing k8_cpufixup, which is wrong. Just a reminder, make your stuff testing against ==1, not ifdef. Second, a subtle change in the config tool. IF: a symbol is always exported and has no default value, AND the value is not set by the time the config tool is generating makefile settings, then you will get an error, not just a warning. One error in the EPIA build process was because the symbol 'k8' was defined but had no value. I don't think this will break anything, but you never know. Watch your K8 builds carefully. We're hoping this fixes the latest EPIA problems. ron

Stefan, You may try to increase the heap size in config. I meet such problem in S2882 and solved that by increasing heap size.

AMD64+FILO -> Detected floating bus
by Stefan Reinauer 22 Mar '04

22 Mar '04

Hi, with LinuxBIOS 1.1.6 and Filo 0.4.1 I am getting a floating IDE bus on the Solo machines now. This has worked before with older versions, but I am not sure what might cause this breakage.. Any ideas? Best regards, Stefan Reinauer -- Stefan Reinauer, SUSE LINUX AG Head of Architecture Development

code flow
by Frank 21 Mar '04

21 Mar '04

Is there a document that describes the code flow for freebios. Specifically, I'm trying to figure out the booting process. I've configured and compiled the code for the sis550 but I don't see how the LPC is being configured. The only way I can get the ipl.S to be assembled is to define the docipl rule in the config file. I need to use the LPC bridge for a custom board I will eventually be porting freebios to but I still want to be able to boot from the standard flash device. The way the existing code works is the only way you can compile in the ipl stuff is to define docipl. I will also need to access the LPC bridge to do I2C when reading the spd on the sodimm module. Can anyone suggest how i can include the ipl stuff without the docipl stuff. Another eason I don't want to use the docipl stuff is because the python scripts changes the rom base address to 0x80000. I want the rom base address to be 0xf0000. Any help will greatly appreciated... __________________________________ Do you Yahoo!? Yahoo!
