Revision as of 12:34, 4 September 2008

This is just a work-in-progress status page...

The port is not functional yet.

I started my work on Shuttle SN25P motherboard [[1]] by looking at Supported_Motherboards page, chose a supported one that has similar hardware (ASUS_A8N-E_Build_Tutorial)

Uwe told me where to start modifiying the code to adapt it to motherboard specificities, and more importantly, where to find the information to put in place.

Hardware:

  • AMD K8 Northbridge
  • NVIDIA CK804 Southbridge
  • ITE IT8712F Super I/O
  • AMD Opteron 165 dual core Socket 939

Additionally:

  • RD1 BIOS Savior with XXXX Flash chips for work and backup

OK:

  • flashrom from linux over legacy BIOS
  • Serial console
  • Coreboot runs
  • Load & run payload (tested OK: filo & memtest86)
  • Filo loads a kernel & jump to its entry point
  • Kernel start to boot and hang at the console handling code, right after "Detected 1800.234 MHz processor."

NOK:

  • VGA (not in coreboot, not in filo, not in memtest86, not in linux kernel)
  • Keyboard (idem)
  • Etherboot (onboard nvidia ethernet adapter not properly configured by coreboot)
  • Network

Files:

  • Config.lb - OK
  • mptable.c - should be OK, linux kernel apic=debug output is identical as with legacy BIOS
  • irq_tables.c - should be OK too
  • get_bus_conf.c - WIP, still buggy

Information gathering:

  • getpir - infos for irq_tables.c & mptable.c
  • mptable - infos for mptable.c
  • superiotool - infos for Config.lb device tree
  • lspci -tnvv - PCI bus tree
  • lspci -vvvxx - PCI devices informations
  • setpci -s 0:0:1.0 7c.L - infos for "Initialize interrupt mapping" in mptable.c
  • setpci -s 0:0:1.0 80.L - infos for "Initialize interrupt mapping" in mptable.c
  • setpci -s 0:0:1.0 84.L - infos for "Initialize interrupt mapping" in mptable.c

TODO:

  • Make it boot to Xorg
  • Test onboard HW: SATA, CDROM, USB, Firewire, mouse, keyboard, audio, fan & temperature control
  • PCIe GFX & ethernet
  • HPET
  • ACPI
  • Etherboot for BCM - TG3 PCIe 1x addon card
  • LAB ? (may need bigger flash)
  • Other payloads
