* elilo 3.10 release commit
* Bumped version string to 3.10
* added PTR_FMT 32bit & 64bit pointer translation for correct output
* elilo hang bugfix x86_64 non-standard kernels with non-traditional start address
elilo will pull the start address from the kernel elf header for 2.6
or newer kernels, map memory and use that start address, else use standard
1MB default start address. And handle case of overlapping kernels
and initrds in memory. Patch contributor Stuart Hayes @ Dell,
thanks Stuart!
* ported kernel start adress fix to ia32
* eliminated all possible compiler warnings except those actually
caused by gnu-efi that cant be fixed here.
* Debug output improvement, added pauses with visual feedback when
user sets debug & verbose options.
* bugfix added missing find_bits function definition back into ia32
subtree
* bugfix loader_probe now correctly errors out if no loaders
registered.

===================================
SUBMIT BUG REPORTS HERE --> http://sourceforge.net/tracker/?group_id=91879&atid=598709 BUILD NOTES
====================
You will need the following toolchain to build elilo-3.10 from source
the elilo build environment is optimized for Debian and Debian based distros.
1. gnu-efi3.0d or greater, elilo-3.10 binaries were built with gnu-efi3.0e-2
shipping in Lenny
2. gcc-4.1.1 or greater, elilo-3.10 binaries were built with:
x86 -> 4.2.3-1ubuntu6
x86_64 -> 4.2.3-1ubuntu6
ia64 -> 4.3.2-1.1
3. binutils-2.17.50.0.14 or greater, elilo-3.10 binaries were built with:
x86 -> 2.18.1-cvs20080103-0ubuntu1
x86_64 -> 2.18.1~cvs20080103-0ubuntu1
ia64 -> 2.18.1~cvs20080103-7
IMPORTANT NOTE FOR BUILDS ON ALL ARCHS: * if you use a debian based (lenny)build environment you will have no problems
------------------------- and setting it up is simple. you will be able to build elilo in 3 steps:
1. apt-get install gnu-efi, gcc, binutils
2. apt-get source elilo (or download elilo-3.10.tar.gz from SourceForge.)
3. cd ./elilo-3.10 and type make
You will need the following toolchain to build elilo with the 3.7 source tarball ** If you use the upstream tarballs for the toolchain you will need to move
(for all archs due to the new uefi call wrappers). some files around.
GNU-EFI (provides the efi 1.10 and uefi 2.x libraries & api)
-------
gnu-efi libraries are installed to /usr/local/lib by the
upstream gnu-efi source package. elilo expects them to be in system location
/usr/lib. efi includes may be located in /usr/local/include/efi. elilo
expects them to be in system location /usr/include/efi.
1. gnu-efi-3.0d or > .... http://sourceforge.net/project/showfiles.php?group_id=163609&package_id=185019&release_id=508306 BINUTILS (provides the elf conversion utility to produce efi bins)
--------
2. gcc-4.1.1 or > likewise objcopy may be installed to /usr/local/bin by binutils,
3. binutils-2.17.50.0.14 or > with Intel64 EFI support elilo source expects it to be in /usr/bin.
*BuildNote: efi libraries are installed to /usr/local/lib
by the default gnu-efi source package. elilo expects them to
be in standard linux system location /usr/lib. efi includes
may be located in /usr/local/include/efi. elilo expects
them to be in standard linux system location /usr/include/efi.
likewise objcopy may be installed to /usr/local/bin by binutils,
elilo source expects it to be in /usr/bin. On distributions
using standard linux system conventions such
as Debian and Ubuntu this is corrected in the binutils and gnu-efi packages.
Implementation: ELILO ON EFI X86_64
-------------- =====================
Calls to EFI services in x86_64 require a wrapper to pass the arguments HARD REQUIREMENTS
in the appropriate manner. This is implemented with efi wrapper. Elilo/x86_64 requires efi64 enabled linux kernel i.e. 2.6.21 or newer
For IA32 and IA64, the wrapper is a macro that merely calls the nothing earlier will work, 2.6.21 was the earliest kernel that efi64
EFI services directly. The elilo source has been modified to use the support went into. You need to compile the kernel with CONFIG_EFI
efi wrapper implemented in the gnu-efi-3.0d library. kernel option ON.
elilo for x86_64 and its dependent libraries are built and the final x86_64 platforms with UEFI 2.0 firmware deprecate UGA protocol
ELF image is converted into PE-COFF image using the objcopy supported and therefore only the Graphics Output Protocol (GOP) is supported. For
by binutils-2.17.50.0.14 or above with Intel64 EFI support. such platforms, the kernel must be compiled with EFI_FB option ON. This
will enable early boot messages on the console. Elilo for x86_64
attempts to query EFI for GOP support and if it fails it defaults to
text mode which may or may not show you early console ouput depends on
your efi and physical setup. If efi default console ouput is set to
serial and you dont have anything attached to the serial port then youre
not going to see messages from elilo, duh.
On UEFI 2.0 firmware, only Graphics Output Protocol (GOP) is supported. WORKING ELILO.CONF FOR EFI X86_64 EXAMPLE
The x86_64 elilo first queries video information from GOP failing which Here is my elilo.conf from my UEFI2.0/x86_64 workstation which uses GOP.
it queries for text mode support. The video information is passed to shows me console output, what elilo is doing, and kernel boot.
Linux kernel via boot parameter. The GOP support requires
Linux kernel EFI framebuffer driver (kernel configuration option).
Booting on EFI/x86_64 platforms default=UBUNTU
----------------------------- chooser=simple
verbose=5
delay=30
append="root=/dev/sda3 vga=0x31e splash showopts"
To use elilo on x86_64, you can put it on a floppy and image=/vmlinuz-2.6.24-23-generic
on a FAT32 partition (msdos partition). You can also label="UBUNTU"
netboot if your network adapter has support for UNDI/PXE. description="Ubuntu 2.6.24-23-generic kernel"
initrd=/initrd.img-2.6.24-23-generic
Elilo/x86_64 requires efi64 enabled linux kernel (> 2.6.21).
You need to compile the kernel with CONFIG_EFI option.
x86_64 platforms with UEFI 2.0 firmware deprecate UGA protocol
and therefore only the Graphics Output Protocol (GOP) is supported. For
such platforms, the kernel must be configured with EFI_FB option. This
will enable early boot messages on the console. The elilo for x86_64
attempts to query the firmware for GOP and if it fails it defaults to
text mode.
The x86_64 implementation converts the EFI memory map into E820 map and CHANGES FROM 3.8 TO 3.10
passes it in the bootparameter supplied to the kernel. For details on ========================
bootparameter, see x86_64/sysdeps.h. Patch contributions from David Lombard @ Intel and Stuart Hayes @ Dell
thank you.
* added PTR_FMT 32bit & 64bit pointer translation for correct output
* elilo hang bugfix x86_64 non-standard kernels with non-traditional start
address elilo will pull the start address from the kernel elf header for 2.6
or newer kernels, map memory and use that start address, else use standard
1MB default start address. And handle case of overlapping kernels
and initrds in memory.
* ported kernel start adress and memory overlap handling to ia32
* eliminated all possible compiler warnings except those actually
caused by gnu-efi that cant be fixed here.
* Debug output improvement, added pauses with visual feedback when
user sets debug or verbose options.
* bugfix added missing find_bits function definition back into ia32
subtree
* bugfix loader_probe now correctly errors out if no loaders
registered.
CHANGES BETWEEN 3.6 & 3.8
-------------------------
- options parsing changed to append root= after append="-- options" to
accomodate xen ia64 support. without this change the option is
passed to the hypervisor instead of the kernel resulting in the
standard kernel panic.
INTEL PATCHES
- E820 memory map is added to IA32 to make it possible for
Linux kernel not to depend on EFI memory map on EFI 32.
- The EFI framebuffer type ID is changed in Linux kernel to
conform to Linux kernel framebuffer type ID grouping rules. So the
EFI framebuffer type ID setting code in ELILO is changed accordingly.
- The boot loader signature of IA32 and x86_64 is redefined to
make it possible for Linux kernel to distinguish whether the
underlying firmware is EFI 32 or EFI 64.
- updates for EFI-2.0 boot support going into linux kernel 2.6.24-rc4
- CL_MAGIC is not supported by 32-bit boot protocol. So, the kernel
command line passing code is changed accordingly.
- bugfix, on some machines efi memmap entries exceed the 128 maximum
for e820 map entries, so consecutive memmap entries with the same
type are merged to bring the count below 128.
- bugfix, uninitialized e820 _nr_map in fill_e820map.
- fixed compile warning for cmdline_addr assignment.
ADDITIONAL CHANGES
- version string updated to 3.8
- fixed x86_64 hang created by initrd images larger than 7mb due
to the code always using the same efi region which on some machines
is only 7mb. code changed to properly have the efi allocator decide
which regions to use based on the total pagecount required by the
size of the initrd to be loaded.
- bugfix, for ia32 and x86_64 code, e820_map[x-1] accesses memory
out of bounds when x=0.
