IMPORTANT information related to the gnu-efi package
|
||||
----------------------------------------------------
|
||||
June 2001
|
||||
|
||||
As of version 3.0, the gnu-efi package is now split in two different packages:
|
||||
|
||||
-> gnu-efi-X.y: contains the EFI library, include files and crt0.
|
||||
|
||||
-> elilo-X.y : contains the ELILO bootloader.
|
||||
|
||||
Note that X.y don't need to match for both packages. However elilo-3.x
|
||||
requires at least gnu-efi-3.0. EFI support for x86_64 is provided in
|
||||
gnu-efi-3.0d.
|
||||
|
||||
Both packages can be downloaded from:

Generating releases from git a very simple process;
|
||||
|
||||
1) Edit the file "Makefile". Changing the "VERSION" line to the new version.
|
||||
2) Do a "git commit" just for the version number change.
|
||||
3) Then do a "make test-archive".
|
||||
That will make a file in the current directory gnu-efi-$VERSION.tar.bz2 ,
|
||||
with its top level directory gnu-efi-$VERSION/ and the source tree under that.
|
||||
|
||||
Once you've tested that and you're sure it's what you want to release,
|
||||
4) Do "make archive", which will tag a release in git and generate a
|
||||
final tarball from it.
|
||||
|
||||
You then push to the archive, being sure to include the tag:
|
||||
5) "git push origin master:master --tags"
|
||||
|
||||
And upload the archive wherever it's supposed to go.

|
||||
* Introduction
|
||||
|
||||
This document has two parts: the first part describes how to develop
|
||||
EFI applications for IA-64,x86 and x86_64 using the GNU toolchain and the EFI
|
||||
development environment contained in this directory. The second part
|
||||
describes some of the more subtle aspects of how this development
|
||||
environment works.
|
||||
|
||||
|
||||
|
||||
* Part 1: Developing EFI Applications
|
||||
|
||||
|
||||
** Prerequisites:
|
||||
|
||||
To develop x86 and x86_64 EFI applications, the following tools are needed:
|
||||
|
||||
- gcc-3.0 or newer (gcc 2.7.2 is NOT sufficient!)
|
||||
As of gnu-efi-3.0b, the Redhat 8.0 toolchain is known to work,
|
||||
but the Redhat 9.0 toolchain is not currently supported.
|
||||
|
||||
- A version of "objcopy" that supports EFI applications. To
|
||||
check if your version includes EFI support, issue the
|
||||
command:
|
||||
|
||||
objcopy --help
|
||||
|
||||
Verify that the line "supported targets" contains the string
|
||||
"efi-app-ia32" and "efi-app-x86_64" and that the "-j" option
|
||||
accepts wildcards. The binutils release binutils-2.24
|
||||
supports Intel64 EFI and accepts wildcard section names.
|
||||
|
||||
- For debugging purposes, it's useful to have a version of
|
||||
"objdump" that supports EFI applications as well. This
|
||||
allows inspect and disassemble EFI binaries.
|
||||
|
||||
To develop IA-64 EFI applications, the following tools are needed:
|
||||
|
||||
- A version of gcc newer than July 30th 1999 (older versions
|
||||
had problems with generating position independent code).
|
||||
As of gnu-efi-3.0b, gcc-3.1 is known to work well.
|
||||
|
||||
- A version of "objcopy" that supports EFI applications. To
|
||||
check if your version includes EFI support, issue the
|
||||
command:
|
||||
|
||||
objcopy --help
|
||||
|
||||
Verify that the line "supported targets" contains the string
|
||||
"efi-app-ia64" and that the "-j" option accepts wildcards.
|
||||
|
||||
- For debugging purposes, it's useful to have a version of
|
||||
"objdump" that supports EFI applications as well. This
|
||||
allows inspect and disassemble EFI binaries.
|
||||
|
||||
|
||||
** Directory Structure
|
||||
|
||||
This EFI development environment contains the following
|
||||
subdirectories:
|
||||
|
||||
inc: This directory contains the EFI-related include files. The
|
||||
files are taken from Intel's EFI source distribution, except
|
||||
that various fixes were applied to make it compile with the
|
||||
GNU toolchain.
|
||||
|
||||
lib: This directory contains the source code for Intel's EFI library.
|
||||
Again, the files are taken from Intel's EFI source
|
||||
distribution, with changes to make them compile with the GNU
|
||||
toolchain.
|
||||
|
||||
gnuefi: This directory contains the glue necessary to convert ELF64
|
||||
binaries to EFI binaries. Various runtime code bits, such as
|
||||
a self-relocator are included as well. This code has been
|
||||
contributed by the Hewlett-Packard Company and is distributed
|
||||
under the GNU GPL.
|
||||
|
||||
apps: This directory contains a few simple EFI test apps.
|
||||
|
||||
** Setup
|
||||
|
||||
It is necessary to edit the Makefile in the directory containing this
|
||||
README file before EFI applications can be built. Specifically, you
|
||||
should verify that macros CC, AS, LD, AR, RANLIB, and OBJCOPY point to
|
||||
the appropriate compiler, assembler, linker, ar, and ranlib binaries,
|
||||
respectively.
|
||||
|
||||
If you're working in a cross-development environment, be sure to set
|
||||
macro ARCH to the desired target architecture ("ia32" for x86, "x86_64" for
|
||||
x86_64 and "ia64" for IA-64). For convenience, this can also be done from
|
||||
the make command line (e.g., "make ARCH=ia64").
|
||||
|
||||
|
||||
** Building
|
||||
|
||||
To build the sample EFI applications provided in subdirectory "apps",
|
||||
simply invoke "make" in the toplevel directory (the directory
|
||||
containing this README file). This should build lib/libefi.a and
|
||||
gnuefi/libgnuefi.a first and then all the EFI applications such as a
|
||||
apps/t6.efi.
|
||||
|
||||
|
||||
** Running
|
||||
|
||||
Just copy the EFI application (e.g., apps/t6.efi) to the EFI
|
||||
filesystem, boot EFI, and then select "Invoke EFI application" to run
|
||||
the application you want to test. Alternatively, you can invoke the
|
||||
Intel-provided "nshell" application and then invoke your test binary
|
||||
via the command line interface that "nshell" provides.
|
||||
|
||||
|
||||
** Writing Your Own EFI Application
|
||||
|
||||
Suppose you have your own EFI application in a file called
|
||||
"apps/myefiapp.c". To get this application built by the GNU EFI build
|
||||
environment, simply add "myefiapp.efi" to macro TARGETS in
|
||||
apps/Makefile. Once this is done, invoke "make" in the top level
|
||||
directory. This should result in EFI application apps/myefiapp.efi,
|
||||
ready for execution.
|
||||
|
||||
The GNU EFI build environment allows to write EFI applications as
|
||||
described in Intel's EFI documentation, except for two differences:
|
||||
|
||||
- The EFI application's entry point is always called "efi_main". The
|
||||
declaration of this routine is:
|
||||
|
||||
EFI_STATUS efi_main (EFI_HANDLE image, EFI_SYSTEM_TABLE *systab);
|
||||
|
||||
- UNICODE string literals must be written as W2U(L"Sample String")
|
||||
instead of just L"Sample String". The W2U() macro is defined in
|
||||
<efilib.h>. This header file also declares the function W2UCpy()
|
||||
which allows to convert a wide string into a UNICODE string and
|
||||
store the result in a programmer-supplied buffer.
|
||||
|
||||
- Calls to EFI services should be made via uefi_call_wrapper(). This
|
||||
ensures appropriate parameter passing for the architecture.
|
||||
|
||||
|
||||
* Part 2: Inner Workings
|
||||
|
||||
WARNING: This part contains all the gory detail of how the GNU EFI
|
||||
toolchain works. Normal users do not have to worry about such
|
||||
details. Reading this part incurs a definite risk of inducing severe
|
||||
headaches or other maladies.
|
||||
|
||||
The basic idea behind the GNU EFI build environment is to use the GNU
|
||||
toolchain to build a normal ELF binary that, at the end, is converted
|
||||
to an EFI binary. EFI binaries are really just PE32+ binaries. PE
|
||||
stands for "Portable Executable" and is the object file format
|
||||
Microsoft is using on its Windows platforms. PE is basically the COFF
|
||||
object file format with an MS-DOS2.0 compatible header slapped on in
|
||||
front of it. The "32" in PE32+ stands for 32 bits, meaning that PE32
|
||||
is a 32-bit object file format. The plus in "PE32+" indicates that
|
||||
this format has been hacked to allow loading a 4GB binary anywhere in
|
||||
a 64-bit address space (unlike ELF64, however, this is not a full
|
||||
64-bit object file format because the entire binary cannot span more
|
||||
than 4GB of address space). EFI binaries are plain PE32+ binaries
|
||||
except that the "subsystem id" differs from normal Windows binaries.
|
||||
There are two flavors of EFI binaries: "applications" and "drivers"
|
||||
and each has there own subsystem id and are identical otherwise. At
|
||||
present, the GNU EFI build environment supports the building of EFI
|
||||
applications only, though it would be trivial to generate drivers, as
|
||||
the only difference is the subsystem id. For more details on PE32+,
|
||||
see the spec at
|
||||
|
||||
http://msdn.microsoft.com/library/specs/msdn_pecoff.htm.
|
||||
|
||||
In theory, converting a suitable ELF64 binary to PE32+ is easy and
|
||||
could be accomplished with the "objcopy" utility by specifying option
|
||||
--target=efi-app-ia32 (x86) or --target=efi-app-ia64 (IA-64). But
|
||||
life never is that easy, so here some complicating factors:
|
||||
|
||||
(1) COFF sections are very different from ELF sections.
|
||||
|
||||
ELF binaries distinguish between program headers and sections.
|
||||
The program headers describe the memory segments that need to
|
||||
be loaded/initialized, whereas the sections describe what
|
||||
constitutes those segments. In COFF (and therefore PE32+) no
|
||||
such distinction is made. Thus, COFF sections need to be page
|
||||
aligned and have a size that is a multiple of the page size
|
||||
(4KB for EFI), whereas ELF allows sections at arbitrary
|
||||
addresses and with arbitrary sizes.
|
||||
|
||||
(2) EFI binaries should be relocatable.
|
||||
|
||||
Since EFI binaries are executed in physical mode, EFI cannot
|
||||
guarantee that a given binary can be loaded at its preferred
|
||||
address. EFI does _try_ to load a binary at it's preferred
|
||||
address, but if it can't do so, it will load it at another
|
||||
address and then relocate the binary using the contents of the
|
||||
.reloc section.
|
||||
|
||||
(3) On IA-64, the EFI entry point needs to point to a function
|
||||
descriptor, not to the code address of the entry point.
|
||||
|
||||
(4) The EFI specification assumes that wide characters use UNICODE
|
||||
encoding.
|
||||
|
||||
ANSI C does not specify the size or encoding that a wide
|
||||
character uses. These choices are "implementation defined".
|
||||
On most UNIX systems, the GNU toolchain uses a wchar_t that is
|
||||
4 bytes in size. The encoding used for such characters is
|
||||
(mostly) UCS4.
|
||||
|
||||
In the following sections, we address how the GNU EFI build
|
||||
environment addresses each of these issues.
|
||||
|
||||
|
||||
** (1) Accommodating COFF Sections
|
||||
|
||||
In order to satisfy the COFF constraint of page-sized and page-aligned
|
||||
sections, the GNU EFI build environment uses the special linker script
|
||||
in gnuefi/elf_$(ARCH)_efi.lds where $(ARCH) is the target architecture
|
||||
("ia32" for x86, "x86_64" for x86_64 and "ia64" for IA-64).
|
||||
This script is set up to create only eight COFF section, each page aligned
|
||||
and page sized.These eight sections are used to group together the much
|
||||
greater number of sections that are typically present in ELF object files.
|
||||
Specifically:
|
||||
|
||||
.hash (and/or .gnu.hash)
|
||||
Collects the ELF .hash info (this section _must_ be the first
|
||||
section in order to build a shared object file; the section is
|
||||
not actually loaded or used at runtime).
|
||||
|
||||
GNU binutils provides a mechanism to generate different hash info
|
||||
via --hash-style=<sysv|gnu|both> option. In this case output
|
||||
shared object will contain .hash section, .gnu.hash section or
|
||||
both. In order to generate correct output linker script preserves
|
||||
both types of hash sections.
|
||||
|
||||
.text
|
||||
Collects all sections containing executable code.
|
||||
|
||||
.data
|
||||
Collects read-only and read-write data, literal string data,
|
||||
global offset tables, the uninitialized data segment (bss) and
|
||||
various other sections containing data.
|
||||
|
||||
The reason read-only data is placed here instead of the in
|
||||
.text is to make it possible to disassemble the .text section
|
||||
without getting garbage due to read-only data. Besides, since
|
||||
EFI binaries execute in physical mode, differences in page
|
||||
protection do not matter.
|
||||
|
||||
The reason the uninitialized data is placed in this section is
|
||||
that the EFI loader appears to be unable to handle sections
|
||||
that are allocated but not loaded from the binary.
|
||||
|
||||
.dynamic, .dynsym, .rela, .rel, .reloc
|
||||
These sections contains the dynamic information necessary to
|
||||
self-relocate the binary (see below).
|
||||
|
||||
A couple of more points worth noting about the linker script:
|
||||
|
||||
o On IA-64, the global pointer symbol (__gp) needs to be placed such
|
||||
that the _entire_ EFI binary can be addressed using the signed
|
||||
22-bit offset that the "addl" instruction affords. Specifically,
|
||||
this means that __gp should be placed at ImageBase + 0x200000.
|
||||
Strictly speaking, only a couple of symbols need to be addressable
|
||||
in this fashion, so with some care it should be possible to build
|
||||
binaries much larger than 4MB. To get a list of symbols that need
|
||||
to be addressable in this fashion, grep the assembly files in
|
||||
directory gnuefi for the string "@gprel".
|
||||
|
||||
o The link address (ImageBase) of the binary is (arbitrarily) set to
|
||||
zero. This could be set to something larger to increase the chance
|
||||
of EFI being able to load the binary without requiring relocation.
|
||||
However, a start address of 0 makes debugging a wee bit easier
|
||||
(great for those of us who can add, but not subtract... ;-).
|
||||
|
||||
o The relocation related sections (.dynamic, .rel, .rela, .reloc)
|
||||
cannot be placed inside .data because some tools in the GNU
|
||||
toolchain rely on the existence of these sections.
|
||||
|
||||
o Some sections in the ELF binary intentionally get dropped when
|
||||
building the EFI binary. Particularly noteworthy are the dynamic
|
||||
relocation sections for the .plabel and .reloc sections. It would
|
||||
be _wrong_ to include these sections in the EFI binary because it
|
||||
would result in .reloc and .plabel being relocated twice (once by
|
||||
the EFI loader and once by the self-relocator; see below for a
|
||||
description of the latter). Specifically, only the sections
|
||||
mentioned with the -j option in the final "objcopy" command are
|
||||
retained in the EFI binary (see Make.rules).
|
||||
|
||||
|
||||
** (2) Building Relocatable Binaries
|
||||
|
||||
ELF binaries are normally linked for a fixed load address and are thus
|
||||
not relocatable. The only kind of ELF object that is relocatable are
|
||||
shared objects ("shared libraries"). However, even those objects are
|
||||
usually not completely position independent and therefore require
|
||||
runtime relocation by the dynamic loader. For example, IA-64 binaries
|
||||
normally require relocation of the global offset table.
|
||||
|
||||
The approach to building relocatable binaries in the GNU EFI build
|
||||
environment is to:
|
||||
|
||||
(a) build an ELF shared object
|
||||
|
||||
(b) link it together with a self-relocator that takes care of
|
||||
applying the dynamic relocations that may be present in the
|
||||
ELF shared object
|
||||
|
||||
(c) convert the resulting image to an EFI binary
|
||||
|
||||
The self-relocator is of course architecture dependent. The x86
|
||||
version can be found in gnuefi/reloc_ia32.c, the x86_64 version
|
||||
can be found in gnuefi/reloc_x86_64.c and the IA-64 version can be
|
||||
found in gnuefi/reloc_ia64.S.
|
||||
|
||||
The self-relocator operates as follows: the startup code invokes it
|
||||
right after EFI has handed off control to the EFI binary at symbol
|
||||
"_start". Upon activation, the self-relocator searches the .dynamic
|
||||
section (whose starting address is given by symbol _DYNAMIC) for the
|
||||
dynamic relocation information, which can be found in the DT_REL,
|
||||
DT_RELSZ, and DT_RELENT entries of the dynamic table (DT_RELA,
|
||||
DT_RELASZ, and DT_RELAENT in the case of rela relocations, as is the
|
||||
case for IA-64). The dynamic relocation information points to the ELF
|
||||
relocation table. Once this table is found, the self-relocator walks
|
||||
through it, applying each relocation one by one. Since the EFI
|
||||
binaries are fully resolved shared objects, only a subset of all
|
||||
possible relocations need to be supported. Specifically, on x86 only
|
||||
the R_386_RELATIVE relocation is needed. On IA-64, the relocations
|
||||
R_IA64_DIR64LSB, R_IA64_REL64LSB, and R_IA64_FPTR64LSB are needed.
|
||||
Note that the R_IA64_FPTR64LSB relocation requires access to the
|
||||
dynamic symbol table. This is why the .dynsym section is included in
|
||||
the EFI binary. Another complication is that this relocation requires
|
||||
memory to hold the function descriptors (aka "procedure labels" or
|
||||
"plabels"). Each function descriptor uses 16 bytes of memory. The
|
||||
IA-64 self-relocator currently reserves a static memory area that can
|
||||
hold 100 of these descriptors. If the self-relocator runs out of
|
||||
space, it causes the EFI binary to fail with error code 5
|
||||
(EFI_BUFFER_TOO_SMALL). When this happens, the manifest constant
|
||||
MAX_FUNCTION_DESCRIPTORS in gnuefi/reloc_ia64.S should be increased
|
||||
and the application recompiled. An easy way to count the number of
|
||||
function descriptors required by an EFI application is to run the
|
||||
command:
|
||||
|
||||
objdump --dynamic-reloc example.so | fgrep FPTR64 | wc -l
|
||||
|
||||
assuming "example" is the name of the desired EFI application.
|
||||
|
||||
|
||||
** (3) Creating the Function Descriptor for the IA-64 EFI Binaries
|
||||
|
||||
As mentioned above, the IA-64 PE32+ format assumes that the entry
|
||||
point of the binary is a function descriptor. A function descriptors
|
||||
consists of two double words: the first one is the code entry point
|
||||
and the second is the global pointer that should be loaded before
|
||||
calling the entry point. Since the ELF toolchain doesn't know how to
|
||||
generate a function descriptor for the entry point, the startup code
|
||||
in gnuefi/crt0-efi-ia64.S crafts one manually by with the code:
|
||||
|
||||
.section .plabel, "a"
|
||||
_start_plabel:
|
||||
data8 _start
|
||||
data8 __gp
|
||||
|
||||
this places the procedure label for entry point _start in a section
|
||||
called ".plabel". Now, the only problem is that _start and __gp need
|
||||
to be relocated _before_ EFI hands control over to the EFI binary.
|
||||
Fortunately, PE32+ defines a section called ".reloc" that can achieve
|
||||
this. Thus, in addition to manually crafting the function descriptor,
|
||||
the startup code also crafts a ".reloc" section that has will cause
|
||||
the EFI loader to relocate the function descriptor before handing over
|
||||
control to the EFI binary (again, see the PECOFF spec mentioned above
|
||||
for details).
|
||||
|
||||
A final question may be why .plabel and .reloc need to go in their own
|
||||
COFF sections. The answer is simply: we need to be able to discard
|
||||
the relocation entries that are generated for these sections. By
|
||||
placing them in these sections, the relocations end up in sections
|
||||
".rela.plabel" and ".rela.reloc" which makes it easy to filter them
|
||||
out in the filter script. Also, the ".reloc" section needs to be in
|
||||
its own section so that the objcopy program can recognize it and can
|
||||
create the correct directory entries in the PE32+ binary.
|
||||
|
||||
|
||||
** (4) Convenient and Portable Generation of UNICODE String Literals
|
||||
|
||||
As of gnu-efi-3.0, we make use (and somewhat abuse) the gcc option
|
||||
that forces wide characters (WCHAR_T) to use short integers (2 bytes)
|
||||
instead of integers (4 bytes). This way we match the Unicode character
|
||||
size. By abuse, we mean that we rely on the fact that the regular ASCII
|
||||
characters are encoded the same way between (short) wide characters
|
||||
and Unicode and basically only use the first byte. This allows us
|
||||
to just use them interchangeably.
|
||||
|
||||
The gcc option to force short wide characters is : -fshort-wchar

||||
published from being rewound.
|
||||
|
||||
The workflow assumed here is:
|
||||
|
||||
* Once a topic branch forks from "master", "master" is never
|
||||
merged into it again (either directly or indirectly).
|
||||
|
||||
* Once a topic branch is fully cooked and merged into "master",
|
||||
it is deleted. If you need to build on top of it to correct
|
||||
earlier mistakes, a new topic branch is created by forking at
|
||||
the tip of the "master". This is not strictly necessary, but
|
||||
it makes it easier to keep your history simple.
|
||||
|
||||
* Whenever you need to test or publish your changes to topic
|
||||
branches, merge them into "next" branch.
|
||||
|
||||
The script, being an example, hardcodes the publish branch name
|
||||
to be "next", but it is trivial to make it configurable via
|
||||
$GIT_DIR/config mechanism.
|
||||
|
||||
With this workflow, you would want to know:
|
||||
|
||||
(1) ... if a topic branch has ever been merged to "next". Young
|
||||
topic branches can have stupid mistakes you would rather
|
||||
clean up before publishing, and things that have not been
|
||||
merged into other branches can be easily rebased without
|
||||
affecting other people. But once it is published, you would
|
||||
not want to rewind it.
|
||||
|
||||
(2) ... if a topic branch has been fully merged to "master".
|
||||
Then you can delete it. More importantly, you should not
|
||||
build on top of it -- other people may already want to
|
||||
change things related to the topic as patches against your
|
||||
"master", so if you need further changes, it is better to
|
||||
fork the topic (perhaps with the same name) afresh from the
|
||||
tip of "master".
|
||||
|
||||
Let's look at this example:
|
||||
|
||||
o---o---o---o---o---o---o---o---o---o "next"
|
||||
/ / / /
|
||||
/ a---a---b A / /
|
||||
/ / / /
|
||||
/ / c---c---c---c B /
|
||||
/ / / \ /
|
||||
/ / / b---b C \ /
|
||||
/ / / / \ /
|
||||
---o---o---o---o---o---o---o---o---o---o---o "master"
|
||||
|
||||
|
||||
A, B and C are topic branches.
|
||||
|
||||
* A has one fix since it was merged up to "next".
|
||||
|
||||
* B has finished. It has been fully merged up to "master" and "next",
|
||||
and is ready to be deleted.
|
||||
|
||||
* C has not merged to "next" at all.
|
||||
|
||||
We would want to allow C to be rebased, refuse A, and encourage
|
||||
B to be deleted.
|
||||
|
||||
To compute (1):
|
||||
|
||||
git rev-list ^master ^topic next
|
||||
git rev-list ^master next
|
||||
|
||||
if these match, topic has not merged in next at all.
|
||||
|
||||
To compute (2):
|
||||
|
||||
git rev-list master..topic
|
||||
|
||||
if this is empty, it is fully merged to "master".
