after loading such a kernel, "module_path" will be set to
an insane value. Fixed example by providing an equivalent
setting. For the record, when automatically loading a
kernel (commands "boot" and "boot-conf"), the following is
tried, in this order:
path=/boot/${kernel} file=${bootfile}
path=/boot/${kernel} file=${kernel}
path=${kernel} file=${bootfile}
path=${kernel} file=${kernel}
path=${module_path} file=${kernel}
use <machine/efi.h> for the necessary definitions. This makes the EFI
code in sys/boot/efi totally unused, except for pure EFI loaders. As
such, maintenance and porting (to IA-32) of the EFI code is made as easy
as possible.
to 4.0 and RELENG_3), the BTX mini-kernel used paging rather than flat
mode and clients were limited to a virtual address space of 16 megabytes.
Because of this limitation, boot2 silently masked all physical addresses
in any binaries it loaded so that they were always loaded into the first
16 Meg. Since BTX no longer has this limitation (and hasn't for a long
time), remove the masking from boot2. This allows boot2 to load kernels
larger than about 12 to 14 meg (12 for non-PAE, 14 for PAE).

format modules, which are currently only used on the amd64 platform.
This initial implementation just parses enough of the module to
allow it to extract dependencies and load all the bits into the
right place in memory, so the kernel must still do the full relocation
and linking. The details of the loaded sections are passed to the
kernel by supplying a copy of the ELF section header table as module
metadata with the MODINFOMD_SHDR tag.
better relocation support for the amd64 and i386 platforms. This
should not result in any change in functionality, but moves a step
towards supporting the relocatable object file modules on amd64.
The same hack/trick as load_elf*.c uses is used here to simultaneously
support both elf32 and elf64 on amd64 and i386.
This way of operation is more robust than the "AI" used
before.
Add flags to mbr accessible from make.conf as BOOT_MBR_FLAGS.
Only one flag is defined now, "allow using packet mode", which
is 0x80 in accord with the rest of i386 boot code. The "packet"

The whole problem seems to be size. Which is odd, because it is said
that size doesn't matter. Anyway... Add -Os to strategic places in the
makefile to have the final loader be as mall as possible. This seems
to be enough to make it work. For now... I think something is more
fundamentally wrong; or something more fundamental is wrong. Potato,
potaato.
The binutils 2.15 assembler now automaticly and non-optionally adds
the .eh_frame section for unwind information. This section appears
to wreck havoc to the final boot code. Fix this by using a special
linker script that discards the .eh_frame sections, but is otherwise
identical to the linker internal script used for -N.

Likewise, we copied the .rela section to the EFI image, but not

in the linker script so that all relocations end up in the same

uses ttya as the console in this case and people probably expect
FreeBSD to do the same (it's also very handy to temporarily switch
consoles)..."

Has no doubt that the change is correct: marcel
to build the kernel. It doesn't affect the operation if gcc.
Most of the changes are just adding __INTEL_COMPILER to #ifdef's, as
icc v8 may define __GNUC__ some parts may look strange but are
necessary.
Additional changes:
- in_cksum.[ch]:
* use a generic C version instead of the assembly version in the !gcc
case (ASM code breaks with the optimizations icc does)
-> no bad checksums with an icc compiled kernel

The entire checksum code should IMHO be replaced with the DragonFly
version (because it isn't guaranteed future revisions of gcc will
include similar optimizations) as in:
