Merging busses into bus 0 is an interesting logicistics feat, but the current infrastructure will allow it. > Can this cause trouble with current board implementations?

Right now each Hypertransport chains appears to be it's own bus and all of that information is dynamically calculated. The busses that are Hypertranpsort chains are enumerated just like other busses. The way to look at the code is that: - device.c has the logic to enumerate and assign resources to devices and busses. - pci_device.c has the methods for doing that on pci devices. - hypertransport.c has the methods for doing that with hypertranport devices. - northbridge/amd/amdk8/northbridge.c has the drivers for the amdk8 specific northbridge. In short dynamic resource assignment should now be pretty simple and should remove the need for most of the hard codes. I have committed the code not in a final perfect state. But in a state where it works well enough to be useful. And whatever details we encounter are minor things. Passing information to the dynamic device tree from the static device tree is currently a weak area. But we are building one tree from the other so it is just a matter of a small amount of refactoring if we want to do something better. Basically what remains is to dive into the code see what it is doing, and tweak it a little if is not doing quite the right thing. But usually all that needs to happen is to improve a method of a device so that it operates better. Eric

Eric, Without hard_reset, s2885 is ok now. In the k8/cpufixup.c need compare mmio_basek and 0x3f0000 and then assign that to TOM.

And the 8131 on link2 and 8151 on link0 all show out. Maybe you can add MACRO to control reverse scan for AMKK8 northbridge. ( link2 then link0) But it continues to reboot.

National SC1200 with DP83815 Ethernetcontroller problem
by Bernd Mödeker 10 Sep '03

10 Sep '03

Hi list, all SC1200 internal devices were correctly detected by pci bus scan. But the only external device DP83815 count'nt be detected. Scanning PCI bus...PCI: pci_scan_bus for bus 0 POST: 0x24 PCI: 00:00.0 [1078/0001] PCI: 00:12.0 [100b/0500] PCI: 00:12.1 [100b/0501] PCI: 00:12.2 [100b/0502] PCI: 00:12.3 [100b/0503] PCI: 00:12.4 [100b/0504] PCI: 00:12.5 [100b/0505] PCI: 00:13.0 [0e11/a0f8] POST: 0x25 I am missing: PCI: 00:0E.0 [100b/0020] After some measurements I saw that there is a PCI frame generated during an access, but no ADxx signals are high during this frame. Normally AD24 which is connected to IDSEL of the Ethernetcontroller should be "high". So the DP83815 don't think that he is selected. My suggestion is that the external pci bus is not correct initialized. I attached some files of my configuration. Has anybody some advises to me? Thanks Benno Sorry for sending to admin

Heads up - /proc/kcore May Be Going Away
by prl-linuxbios＠sychron.com 10 Sep '03

10 Sep '03

Noticed this on kernel traffic shortly after noting that the description of extracting Video BIOS in the ADLO paper uses /dev/kcore. I take it that there'd be no problem in creating a more specialised architecture specific device for extracting things like parts of the BIOS. http://kt.zork.net/kernel-traffic/kt20030908_229.html#5

more than a segment of code
by Stefan Reinauer 10 Sep '03

10 Sep '03

Hi, I'm trying to adopt the AMD Quartet target to the new config scheme completely, but until now I failed when using the code I checked into CVS. The static tables and structures like the mem_controller cpu[] are twice as big as with the HDAMA most of the time, so the image does not fit in 64k anymore: /usr/lib/gcc-lib/i486-suse-linux/3.3/../../../../i486-suse-linux/bin/ld: section .reset [00000000fffffff0 -> 00000000ffffffff] overlaps section .payload [00000000ffffb5b0 -> 00000001000008ca] /usr/lib/gcc-lib/i486-suse-linux/3.3/../../../../i486-suse-linux/bin/ld: section .id [00000000ffffffd8 -> 00000000ffffffef] overlaps section .payload [00000000ffffb5b0 -> 00000001000008ca] When I set the image size to 128k (ROM_IMAGE_SIZE), I get /home/stepan/LinuxBIOS/freebios2/src/cpu/i386/reset16.inc:16:3: #error _ROMBASE is an unsupported value Is there any solution except stripping down?

more on the arima/hdama pci bus problem
by ron minnich 10 Sep '03

10 Sep '03

the 8111 is being put on pci bus 1, but Linux never sees it. I'm not totally clear yet on why this is happening, but I've got to work on a different problem with this board, so if anyone has any suggestions I'll try them out later. thanks ron

overriding command line options in LinuxBIOS
by Adam Agnew 10 Sep '03

10 Sep '03

Are there currently any elf loaders that boot under linuxbios which will let you change the default command line in kernel's made with mkelfImage from the serial console? If not, can someone point me to an example of anywhere this works, perhaps outside of linuxbios? I'd like to add it. Thanks! - Adam Agnew

linuxbios, linux, hyperthreading, ACPI, and 2.4.22
by ron minnich 09 Sep '03

09 Sep '03

We're seeing an interesting problem here. 2.4.22 appears to want to rely on ACPI tables for information on hyperthreading. Diffs seem to show that the linux code that works directly with the hardware to work out hyperthreading is gone. What's happened now is that a dell box, without acpi bios support, will no longer enable hyperthreading. Turn the ACPI support on, and, on the occasions when 2.4.22 doesn't panic when coming up, it does find hyperthreaded CPUs. To panic 2.4.22 while coming up, just hit random keyboard characters while it is engaged in working out hyperthreading. It dies or, sometimes, locks up. This seems like a counterproductive change to me, as it moves Linux more in the direction of depending on factory BIOSes which may, at times, be broken. Has anyone else looked at 2.4.22, and can they confirm or disprove what we think we're seeing? thanks ron
