EFI

Summary

(from uefi.org) UEFI stands for "Unified Extensible Firmware Interface". The UEFI specification defines a new model for the interface between personal-computer operating systems and platform firmware. The interface consists of data tables that contain platform-related information, plus boot and runtime service calls that are available to the operating system and its loader. Together, these provide a standard environment for booting an operating system and running pre-boot applications.

Detailed Description

EFI has long been available for ia64 systems. UEFI brings it to i386 (the Intel-based Apple Mac products have it, as do a few HP systems sold primarily in China), and it will be widely available in x86_64-capable systems in the next few years.

Several things need to happen (in no particular order):

  • GRUB needs to learn to read an EFI GUID Partition Table. (done)
  • GRUB needs to run as an EFI boot loader. (done)
  • GRUB needs to be ported to build and run on ia64 so elilo can be dropped (not done)
  • Kernel needs i386 and x86_64 CONFIG_EFI code (should be easier after the 2.6.24 merge into x86) (done)
  • Kernel needs CONFI_FB_IMAC and CONFIG_FB_EFI merge upstream (done)
  • Kernel needs CONFIG_FB_EFI and associated driver (efifb) (done)
  • Kernel needs CONFIG_FB_IMAC (imacfb support) for Intel Macs (obviated; pjones merged this into efifb)
  • GRUB needs to write out screen_info from UGA so we can use efifb instead of imacfb (done)
  • Kernel needs CONFIG_EFI_VARS enabled on i386 and x86_64 (done)
  • efibootmgr needs to be split out from the elilo package (done)


Benefit to Fedora

Hardware enablement.

Scope

Well-contained. grub, efibootmgr as described above, for 3 platforms.

Test Plan

UEFI-capable systems are available from a number of vendors under NDA. Those with access to such systems will need to perform the testing.

NOTE: Fedora Test Day is planned for UEFI, we will send email announcements to hardware partners once it is scheduled.

Test plan is pretty straightforward. The new components (grub, kernel, efibootmgr) will need to be tested for UEFI functionality.

Architectures: X86 X86_64 IA64

Manufacturer's Platforms: TBD

Each platform should be able to install and boot from: - Internal disk - External disk connected by FC - USB CD - USB DVD - Other USB storage devices TBD - Network devices

Additional test cases: - Variable runtime services, in particular the ability to write to NVRAM - Able to list at least 10 devices as boot devices - Boot from disk > 2TB

User Experience

Significantly similar to that of today. The EFI Boot Manager, which runs in the BIOS, is a new feature, which can be frobbed at runtime using efibootmgr.

Dependencies

Vendor support in hardware

Contingency Plan

Slip to a future Fedora release.

Release Notes

Since the hardware support is not yet widely available and the user impact is negligible, no release note is needed beyond "we support UEFI"
