Peter intro

  • what is coreboot - history - motivation
  • payloads and compression
  • v2/v3
  • cbfs
  • other software in same and related fields
  • sibling projects and utilities: seabios serialice coreinfo bayou libpayload buildrom mkelfImage nvramtool superiotool inteltool msrtool flashrom
  • security issues

Peter technical details

  • modern pc architecture
  • CPU i/o (ports/memory)
  • registers in hardware, "ISA" and PCI
  • NVRAM
  • interrupts
  • PIC APIC PIRQ/MP tables Media:ApicSystem.svg
  • ram init
  • cache-as-ram
  • gcc vs. romcc
  • real mode, protected mode, system management mode
  • mention embedded controllers and capabilities and tasks

Rudolf acpi

  • what for is ACPI
  • Sleep states in more detail - S1 S2 S3 S4 S5
  • CPU power modes C1/C2/C3
  • hardware side - PM regs
  • software architecture of ACPI
  • Tables in more detail
  • Some tour through it acpiextract iasl
  • Coreboot specific stuff - perhaps the ACPIgen
  • and SSDT generation
  • suspend/resume from HW point of view - memory controller stuff too
  • SW flow through coreboot + ram preservation issues

Rudolf board porting

  • Get to know your HW (lspci, superiotool)
  • serial setup + troubles wrong OSC speeds
  • GPIO setup
  • watchdogs - yes ite has default on :)
  • IRQ routing in ACPI? maybe some ideas...
  • ACPI specific stuff for each board
  • porting on supported chipset - describe the early setup for mainboard + directory content for the board
  • some ideas for porting on new unsupported chipset
