cfdb21e905 Source of new Syncbootloader.
Needs commented. Badly.

There will still be some weirdness with linebreaks missing in Print() statements.
Overall, seems to work. It doesn't access QEMU's video buffers, though.
Will work on adding a valid Makefile target for Syncboot soon.
2019-07-20 20:17:07 +01:00
581dd05244 Add new includes for Syncboot rewrite. 2019-07-20 20:15:45 +01:00
83bc1aab50 Shuffle EFI includes around.
Gotta keep them on their toes.
2019-07-20 20:15:29 +01:00
919234eddb Finish migration of working UEFI app.
As you can probably tell, this is based on uefi-simple, by pete.akeo.ie.
2019-07-17 21:18:29 +01:00
d588e232c4 Major overhaul of this branch.
This branch has been dedicated to purely the UEFI bootloader.
As such, all other code has been removed.

This code can be compiled with Visual Studio, gcc or llvm.
2019-07-17 21:10:29 +01:00
352db828e7 Modify existing Makefile to allow compilation of UEFI app.
Added targets for the main files - BOOTX64.EFI, data.c and entry.c
Also minor formatting changes, but whatever.
2019-07-17 15:45:24 +01:00
ab9be9fd4f Finalize removal of BIOS/GRUB artifacts. 2019-07-17 15:44:29 +01:00
c59a95ebfa Populate UEFI entry point. 2019-07-17 15:17:01 +01:00
51641284bc Removal of old LibC project.
That'll have its own branch in future.
2019-07-17 15:13:16 +01:00
e5d8c19422 Formatting and rebranding changes.
Multiboot.h is no longer needed.
2019-07-17 15:12:48 +01:00
4300dc655c Add EFI documentation, libraries and includes.
The lib/inc folders are from the GNU-EFI project.
The documentation is from the uefi.org site.

Yes, I know there are duplicate includes. I have a plan for them.
2019-07-17 15:11:52 +01:00
8f0de18b37 Begin transition to UEFI.
The current system of separating x86 and x86_64 is no longer
feasible with UEFI implementation. UEFI must have its own entry point.

To this end, some optimisations have been implemented in the ASM files.
Everything related to setup has been removed, leaving only the IDT and GDT utility functions.

The linker may be required for the other files, though.

# Sync ##Sync UEFI Bootloader
Sync, an experimental synchronising OS. This branch represents the UEFI bootloader used by Sync.
It tries to set a nice video mode, then gets the date and time, then finds, packs and loads the kernel, giving the information gathered to it.
Currently features: The best way to compile currently is using the compile.sh script provided.
* Text mode printing with CSI support It's far easier to compile on Windows, but ¯\_(?)_/¯
* literally nothing else
Keep posted. Development is relatively active.

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:

README.git
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
