-# 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.

+
+* 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
