Talk:FOSDEM 2010

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
