coherent_ht_mainboard()
by Stefan Reinauer 24 Mar '04

24 Mar '04

Yinghai, tyan/*/hypertransport.c contain some fixed hypertransport register values poked into the AMD K8 northbridge. This code was earlier called by coherent_ht.c:setup_coherent_ht_domain() but I removed the call some time ago, since I could not see why it is still needed. Does this code provide any crucial functionality that can't be realized in the dynamic code of the current CVS tree? If not, I suggest we drop this code. The same thing could btw work for the different versions of resourcemap.c. The biggest reason for the split off here was that the default resource map did always assume the AMD8111 southbridge on link0 which is not always true. This is fixed by now. The bus numbers should meanwhile be entered correctly by the generic code. So, we could reduce the amount of involved code a lot, flattening out all the nasty exceptions we invented to bend the rules..

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 23 Mar '04

23 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
