@chapter Porting
GRUB2 is designed to be easily portable accross platforms. But because of the
nature of bootloader every new port must be done separately. Here is how I did
MIPS (loongson and ARC) and Xen ports. Note than this is more of suggestions,
not absolute truth.
First of all grab any architecture specifications you can find in public
(please avoid NDA).
First stage is ``Hello world''. I've done it outside of GRUB for simplicity.
Your task is to have a small program which is loadable as bootloader and
clearly shows its presence to you. If you have easily accessible console
you can just print a message. If you have a mapped framebuffer you know address
of, you can draw a square. If you have a debug facility, just hanging without
crashing might be enough. For the first stage you can choose to load the
bootloader across the network since format for network image is often easier
than for local boot and it skips the need of small intermediary stages and
nvram handling. Additionally you can often have a good idea of the needed
format by running ``file'' on any netbootable executable for given platform.
This program should probably have 2 parts: an assembler and C one. Assembler one
handles BSS cleaning and other needed setup (on some platforms you may need
to switch modes or copy the executable to its definitive position). So your code
may look like (x86 assembly for illustration purposes)
@example
.globl _start
_start:
movl $_bss_start, %edi
movl $_end, %ecx
subl %edi, %ecx
xorl %eax, %eax
cld
rep
stosb
call main
@end example
@example
static const char msg[] = "Hello, world";
void
putchar (int c)
@{
...
@}
void
main (void)
@{
const char *ptr = msg;
while (*ptr)
putchar (*ptr++);
while (1);
@}
@end example
Sometimes you need a third file: assembly stubs for ABI-compatibility.
Once this file is functional it's time to move it into GRUB2. The startup
assembly file goes to grub-core/kern/$cpu/$platform/startup.S. You should also
include grub/symbol.h and replace call to entry point with call to
EXT_C(grub_main). The C file goes to grub-core/kern/$cpu/$platform/init.c
and its entry point is renamed to void grub_machine_init (void). Keep final
infinite loop for now. Stubs file if any goes to
grub-core/kern/$cpu/$platform/callwrap.S. Sometimes either $cpu or $platform
is dropped if file is used on several cpus respectivelyplatforms.
Check those locations if they already have what you're looking for.
Then modify in configure.ac the following parts:
CPU names:
@example
case "$target_cpu" in
i[[3456]]86) target_cpu=i386 ;;
amd64) target_cpu=x86_64 ;;
sparc) target_cpu=sparc64 ;;
s390x) target_cpu=s390 ;;
...
esac
@end example
Sometimes CPU have additional architecture names which don't influence booting.
You might want to have some canonical name to avoid having bunch of identical
platforms with different names.
NOTE: it doesn't influence compile optimisations which depend solely on
chosen compiler and compile options.
@example
if test "x$with_platform" = x; then
case "$target_cpu"-"$target_vendor" in
i386-apple) platform=efi ;;
i386-*) platform=pc ;;
x86_64-apple) platform=efi ;;
x86_64-*) platform=pc ;;
powerpc-*) platform=ieee1275 ;;
...
esac
else
...
fi
@end example
This part deals with guessing the platform from CPU and vendor. Sometimes you
need to use 32-bit mode for booting even if OS runs in 64-bit one. If so add
your platform to:
@example
case "$target_cpu"-"$platform" in
x86_64-efi) ;;
x86_64-emu) ;;
x86_64-*) target_cpu=i386 ;;
powerpc64-ieee1275) target_cpu=powerpc ;;
esac
@end example
Add your platform to the list of supported ones:
@example
case "$target_cpu"-"$platform" in
i386-efi) ;;
x86_64-efi) ;;
i386-pc) ;;
i386-multiboot) ;;
i386-coreboot) ;;
...
esac
@end example
If explicit -m32 or -m64 is needed add it to:
@example
case "$target_cpu" in
i386 | powerpc) target_m32=1 ;;
x86_64 | sparc64) target_m64=1 ;;
esac
@end example
Finally you need to add a conditional to the following block:
@example
AM_CONDITIONAL([COND_mips_arc], [test x$target_cpu = xmips -a x$platform = xarc])
AM_CONDITIONAL([COND_sparc64_ieee1275], [test x$target_cpu = xsparc64 -a x$platform = xieee1275])
AM_CONDITIONAL([COND_powerpc_ieee1275], [test x$target_cpu = xpowerpc -a x$platform = xieee1275])
@end example
Next stop is gentpl.py. You need to add your platform to the list of supported
ones (sorry that this list is duplicated):
@example
GRUB_PLATFORMS = [ "emu", "i386_pc", "i386_efi", "i386_qemu", "i386_coreboot",
"i386_multiboot", "i386_ieee1275", "x86_64_efi",
"mips_loongson", "sparc64_ieee1275",
"powerpc_ieee1275", "mips_arc", "ia64_efi",
"mips_qemu_mips", "s390_mainframe" ]
@end example
You may also want already to add new platform to one or several of available
groups. In particular we always have a group for each CPU even when only
one platform for given CPU is available.
Then comes grub-core/Makefile.core.def. In the block ``kernel'' you'll need
to define ldflags for your platform ($cpu_$platform_ldflags). You also need to
declare startup asm file ($cpu_$platform_startup) as well as any other files
(e.g. init.c and callwrap.S) (e.g. $cpu_$platform = kern/$cpu/$platform/init.c).
At this stage you will also need to add dummy dl.c and cache.S with functions
grub_err_t grub_arch_dl_check_header (void *ehdr), grub_err_t
grub_arch_dl_relocate_symbols (grub_dl_t mod, void *ehdr) (dl.c) and
void grub_arch_sync_caches (void *address, grub_size_t len) (cache.S). They
won't be used for now.
You will need to create directory include/$cpu/$platform and a file
include/$cpu/types.h. The later folowing this template:
@example
#ifndef GRUB_TYPES_CPU_HEADER
#define GRUB_TYPES_CPU_HEADER 1
/* The size of void *. */
#define GRUB_TARGET_SIZEOF_VOID_P 4
/* The size of long. */
#define GRUB_TARGET_SIZEOF_LONG 4
/* mycpu is big-endian. */
#define GRUB_TARGET_WORDS_BIGENDIAN 1
/* Alternatively: mycpu is little-endian. */
#undef GRUB_TARGET_WORDS_BIGENDIAN
#endif /* ! GRUB_TYPES_CPU_HEADER */
@end example
You will also need to add a dummy file to datetime and setjmp modules to
avoid any of it having no files. It can be just completely empty at this stage.
You'll need to make grub-mkimage.c (util/grub_mkimage.c) aware of the needed
format. For most commonly used formats like ELF, PE, aout or raw the support
is already present and you'll need to make it follow the existant code paths
for your platform adding adjustments if necessary. When done compile:
@example
./autogen.sh
./configure --target=$cpu --with-platform=$platform TARGET_CC=.. OBJCOPY=... STRIP=...
make > /dev/null
@end example
And create image
@example
./grub-mkimage -d grub-core -O $format_id -o test.img
@end example
And it's time to test your test.img.
If it works next stage is to have heap, console and timer.
To have the heap working you need to determine which regions are suitable for
heap usage, allocate them from firmware and map (if applicable). Then call
grub_mm_init_region (vois *start, grub_size_t s) for every of this region.
As a shortcut for early port you can allocate right after _end or have
a big static array for heap. If you do you'll probably need to come back to
this later. As for output console you should distinguish between an array of
text, terminfo or graphics-based console. Many of real-world examples don't
fit perfectly into any of these categories but one of the models is easier
to be used as base. In second and third case you should add your platform to
terminfokernel respectively videoinkernel group. A good example of array of
text is i386-pc (kern/i386/pc/init.c and term/i386/pc/console.c).
Of terminfo is ieee1275 (kern/ieee1275/init.c and term/ieee1275/console.c).
Of video is loongson (kern/mips/loongson/init.c). Note that terminfo has
to be inited in 2 stages: one before (to get at least rudimentary console
as early as possible) and another after the heap (to get full-featured console).
For the input there are string of keys, terminfo and direct hardware. For string
of keys look at i386-pc (same files), for termino ieee1275 (same files) and for
hardware loongson (kern/mips/loongson/init.c and term/at_keyboard.c).
For the timer you'll need to call grub_install_get_time_ms (...) with as sole
argument a function returning a grub_uint64_t of a number of milliseconds
elapsed since arbitrary point in the past.
Once these steps accomplished you can remove the inifinite loop and you should
be able to get to the minimal console. Next step is to have module loading
working. For this you'll need to fill kern/$cpu/dl.c and kern/$cpu/cache.S
with real handling of relocations and respectively the real sync of I and D
caches. Also you'll need to decide where in the image to store the modules.
Usual way is to have it concatenated at the end. In this case you'll need to
modify startup.S to copy modules out of bss to let's say ALIGN_UP (_end, 8)
before cleaning out bss. You'll probably find useful to add total_module_size
field to startup.S. In init.c you need to set grub_modbase to the address
where modules can be found. You may need grub_modules_get_end () to avoid
declaring the space occupied by modules as usable for heap. You can test modules
with:
@example
./grub-mkimage -d grub-core -O $format_id -o test.img hello
@end example
and then running ``hello'' in the shell.
Once this works, you should think of implementing disk access. Look around
disk/ for examples.
Then, very importantly, you probably need to implement the actual loader
(examples available in loader/)
Last step to have minimally usable port is to add support to grub-install to
put GRUB in a place where firmware or platform will pick it up.
Next steps are: filling datetime.c, setjmp.S, network (net/drivers),
video (video/), halt (lib/), reboot (lib/).
Please add your platform to Platform limitations and Supported kernels chapter
in user documentation and mention any steps you skipped which result in reduced
features or performance. Here is the quick checklist of features. Some of them
are less important than others and skipping them is completely ok, just needs
to be mentioned in user documentation.

@node Loopback booting
@section Loopback booting
GRUB is able to read from an image (be it one of CD or HDD) stored on
any of its accessible storages (refer to @pxref{loopback} command).
However the OS itself should be able to find its root. This usually
involves running a userspace program running before the real root
is discovered. This is achieved by GRUB loading a specially made
small image and passing it as ramdisk to the kernel. This is achieved
by commands @command{kfreebsd_module}, @command{knetbsd_module_elf},
@command{kopenbsd_ramdisk}, @command{initrd} (@pxref{initrd}),
@command{initrd16} (@pxref{initrd}), @command{multiboot_module},
@command{multiboot2_module} or @command{xnu_ramdisk}
depending on the loader. Note that for knetbsd the image must be put
inside miniroot.kmod and the whole miniroot.kmod has to be loaded. In
kopenbsd payload this is disabled by default. Aditionally behaviour of
initial ramdisk depends on command line options. Several distributors provide
the image for this purpose or it's integrated in their standard ramdisk and
activated by special option. Consult your kernel and distribution manual for
more details. Other loaders like appleloader, chainloader (BIOS, EFI, coreboot),
freedos, ntldr and plan9 provide no possibility of loading initial ramdisk and
as far as author is aware the payloads in question don't support either initial
ramdisk or discovering loopback boot in other way and as such not bootable this
way. Please consider alternative boot methods like copying all files
from the image to actual partition. Consult your OS documentation for
more details

@samp{[]} means the parameter is optional. @var{device} depends on the disk
driver in use. BIOS and EFI disks use either @samp{fd} or @samp{hd} followed
by a digit, like @samp{fd0}, or @samp{cd}.
AHCI, PATA (ata), crypto, USB use the name of driver followed by a number.
Memdisk and host are limited to one disk and so it's refered just by driver
name.
RAID (md), ofdisk (ieee1275), LVM (lv) and arcdisk (arc) use intrinsic name
of disk prefixed by driver name. Conflicts are solved by suffixing a number
if necessarry. Commas need to be escaped.
Loopback uses whatever name specified to @command{loopback} command.
Hostdisk uses names specified in device.map or hostdisk/<OS NAME>.
For crypto and RAID (md) additionally you can use the syntax
<driver name>uuid/<uuid>.

from one for primary partitions and from five for extended partitions,

such as @samp{a} or @samp{e}.
A shortcut for specifying BSD subpartitions is
@code{(@var{device},@var{bsd-subpart-letter})}, in this case, GRUB
searches for the first PC partition containing a BSD disklabel, then
finds the subpartition @var{bsd-subpart-letter}. Here is an example:

@node Internationalisation
@chapter Charset
GRUB uses UTF-8 internally other than in rendering where some GRUB-specific
appropriate representation is used. All text files (including config) are
assumed to be encoded in UTF-8.
@chapter Filesystems
NTFS, JFS, UDF, HFS+, exFAT, long filenames in FAT, Joliet part of
ISO9660 are treated as UTF-16 as per specification. AFS and BFS are read
as UTF-8, again according to specification. BtrFS, cpio, tar, squash4, minix,
minix2, minix3, ROMFS, ReiserFS, XFS, ext2, ext3, ext4, FAT (short names),
ISO9660 (plain and RockRidge), nilfs2, UFS1, UFS2 and ZFS are assumed
to be UTF-8. This might be false on systems configured with legacy charset
but as long as the charset used is superset of ASCII you should be able to
access ASCII-named files. And it's recommended to configure your system to use
UTF-8 to access the filesystem, convmv may help with migration. AFFS, SFS
and HFS never use unicode and GRUB assumes them to be in Latin1, Latin1
and MacRoman respectively. GRUB handles filesystem case-insensitivity however
no attempt is performed at case conversion of international characters
so e.g. a file named lowercase greek alpha is treated as different from
the one named as uppercase alpha. The filesystems in questions are
NTFS (except POSIX namespace), HFS+ (by default), FAT, exFAT and
ZFS (configurable on per-subvolume basis by property ``casesensitivity'',
default sensitive). On ZFS subvolumes marked as case insensitive files
containing lowercase international characters are inaccessible.
Also like all supported filesystems except HFS+ and ZFS (configurable on
per-subvolume basis by property ``normalization'', default none) GRUB makes
no attempt at check of canonical equivalence so a file name u-diaresis is
treated as distinct from u+combining diaresis. This however means that in
order to access file on HFS+ its name must be specified in normalisation form D.
On normalized ZFS subvolumes filenames out of normalisation are inaccessible.
@chapter Output terminal
Firmware output console ``console'' on ARC and IEEE1275 are limited to ASCII.
BIOS firmware console and VGA text are limited to ASCII and some pseudographics.
None of above mentioned is appropriate for displaying international and any
unsupported character is replaced with question mark except pseudographics
which we attempt to approximate with ASCII. EFI console on the other hand
nominally supports UTF-16 but actual language coverage depends on firmware and
may be very limited. The encoding used on serial can be chosen with
@command{terminfo} as either ASCII, UTF-8 or ``visual UTF-8''. Last one is
against the specification but results in correct rendering of right-to-left
on some readers which don't have own bidi implementation. When using gfxterm
or gfxmenu GRUB itself is responsible for rendering the text. In this case
GRUB is limited by loaded fonts. If fonts contain all required characters
then bidirectional text, cursive variants and combining marks other than
enclosing, half (e.g. left half tilde or combining overline) and double ones.
Ligatures aren't supported though. This should cover European, Middle Eastern
(if you don't mind lack of lam-alif ligature in Arabic) and East Asian scripts.
Notable unsupported scripts are Brahmic family and derived as well as
Mongolian, Tifinagh, Korean Jamo (precomposed characters have no problem)
and tonal writing (2e5-2e9). GRUB also ignores deprecated (as specified
in Unicode) characters (e.g. tags). GRUB also doesn't handle so called
``annotation characters'' If you can complete either of
two lists or, better, propose a patch to improve rendering, please contact
developper team.
@chapter Input terminal
Firmware console on BIOS, IEEE1275 and ARC doesn't allow you to enter non-ASCII
characters. EFI specification allows for such but author is unaware of any
actual implementations. Serial input is currently limited for latin1 (unlikely
to change). Own keyboard implementations (at_keyboard and usb_keyboard)
supports any key but work on one-char-per-keystroke.
So no dead keys or advanced input method. Also there is no keymap change hotkey.
In practice it makes difficult to enter any text using non-Latin alphabet.
Moreover all current input consumers are limited to ASCII.
@chapter Gettext
GRUB supports being translated. For this you need to have language *.mo files in $prefix/locale, load gettext module and set ``lang'' variable.
@chapter Regexp
Regexps work on unicode characters, however no attempt at checking cannonical
equivalence has been made. Moreover the classes like [:alpha:] match only
ASCII subset.
@chapter Other
Currently GRUB always uses YEAR-MONTH-DAY HOUR:MINUTE:SECOND [WEEKDAY] 24-hour
datetime format but weekdays are translated.
GRUB always uses the decimal number format with [0-9] as digits and . as
descimal separator and no group separator.
IEEE1275 aliases are matched case-insensitively except non-ASCII which is
matched as binary. Similar behaviour is for matching OSBundleRequired.
Since IEEE1275 aliases and OSBundleRequired don't contain any non-ASCII it
should never be a problem in practice.
Case-sensitive identifiers are matched as raw strings, no canonical
equivalence check is performed. Case-insenstive identifiers are matched
as RAW but additionally [a-z] is equivalent to [A-Z]. GRUB-defined
identifiers use only ASCII and so should user-defined ones.
Identifiers containing non-ASCII may work but aren't supported.
Only the ASCII space characters (space U+0020, tab U+000b, CR U+000d and
LF U+000a) are recognised. Other unicode space characters aren't a valid
field separator.
@command{test} tests <, >, <=, >=, -pgt and -plt compare the strings in the
lexicographical order of unicode codepoints, replicating the behaviour of
test from coreutils.
environment variables and commands are listed in the same order.

@node Platform limitations
@chapter Platform limitations
GRUB2 is designed to be portable and is actually ported across platforms. We
try to keep all platforms at the level. Unfortunately some platforms are better
supported than others. This is detailed in current and 2 following sections.
ARC platform is unable to change datetime (firmware doesn't seem to provide a
function for it).
EMU has similar limitation.
Console charset refers only to firmware-assisted console. gfxterm is always
Unicode (see Internationalisation section for its limitations). Serial is
configurable to UTF-8 or ASCII (see Internationalisation). In case of qemu
and coreboot ports the refered console is vga_text. Loongson always uses
gfxterm.
Most limited one is ASCII. CP437 provides additionally pseudographics.
GRUB2 doesn't use any language characters from CP437 as often CP437 is replaced
by national encoding compatible only in pseudographics.
Unicode is the most versatile charset which supports many languages. However
the actual console may be much more limited depending on firmware
On BIOS network is supported only if the image is loaded through network.
On sparc64 GRUB is unable to determine which server it was booted from.
On platforms not having direct serial support (as indicated in the line serial)
you can still redirect firmware console to serial if it allows so.
Direct ATA/AHCI support allows to circumvent various firmware limitations but
isn't needed for normal operation except on baremetal ports.
AT keyboard support allows keyboard layout remapping and support for keys not
available through firmware. It isn't needed for normal operation except
baremetal ports.
USB support provides benefits similar to ATA (for USB disks) or AT (for USB
keyboards). In addition it allows USBserial.
Chainloading refers to the ability to load another bootloader through the same protocol
Hints allow faster disk discovery by already knowing in advance which is the disk in
question. On some platforms hints are correct unless you move the disk between boots.
On other platforms it's just an educated guess.
Note that hint failure results in just reduced performance, not a failure
BadRAM is the ability to mark some of the RAM as ``bad''. Note: due to protocol
limitations mips-loongson (with Linux protocol)
and mips-qemu_mips can use only memory up to first hole.
