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
