POSIX-UEFI
|
||||
==========
|
||||
|
||||
```
|
||||
We hate that horrible and ugly UEFI API, we want POSIX!
|
||||
```
|
||||
|
||||
This is a very small library (32k) that helps you to develop for UEFI under Linux (and other POSIX systems). It was greatly
|
||||
inspired by [gnu-efi](https://sourceforge.net/projects/gnu-efi) (big big kudos to those guys), but it is a lot smaller,
|
||||
easier to integrate (works with Clang and GNU gcc both) and easier to use because it provides a POSIX like API.
|
||||
|
||||
To use it, you have to options:
|
||||
|
||||
Distributing as Static Library
|
||||
------------------------------
|
||||
|
||||
In the `uefi` library, run
|
||||
```sh
|
||||
$ make
|
||||
```
|
||||
This will create `build/uefi` with all the necessary files in it. These are:
|
||||
|
||||
- **crt0.o**, the run-time that bootstraps POSIX-UEFI
|
||||
- **link.ld**, the linker script you must use with POSIX-UEFI (same as with gnu-efi)
|
||||
- **libuefi.a**, the library itself
|
||||
- **uefi.h**, the all-in-one C / C++ header
|
||||
|
||||
You can use this and link your application with it, but you won't be able to recompile it, plus you're on your own with
|
||||
the linking and converting.
|
||||
|
||||
Strictly speaking you'll only need **crt0.o** and **link.ld**, that will get you started and will call your application's
|
||||
"main()", but to get libc functions like memcmp, strcpy, malloc or fopen, you'll have to link with **libuefi.a**.
|
||||
|
||||
Distributing as Source
|
||||
----------------------
|
||||
|
||||
This is the preferred way, as it also provides a Makefile to set up your toolchain properly.
|
||||
|
||||
1. simply copy the `uefi` directory into your source tree (or set up a git submodule). Twelfe files, about 140K in total.
|
||||
2. create an extremely simple **Makefile** like below
|
||||
3. compile your code for UEFI by running `make`
|
||||
|
||||
```
|
||||
TARGET = helloworld.efi
|
||||
|
||||
include uefi/Makefile
|
||||
```
|
||||
An example **helloworld.c** goes like this:
|
||||
```c
|
||||
#include <uefi.h>
|
||||
|
||||
int main(int argc, wchar_t **argv)
|
||||
{
|
||||
printf(L"Hello World!\n");
|
||||
return 0;
|
||||
}
|
||||
```
|
||||
|
||||
### Available Makefile Options
|
||||
|
||||
| Variable | Description |
|
||||
|------------|------------------------------------------------------------------------------------------------------|
|
||||
| `TARGET` | the target application (required) |
|
||||
| `SRCS` | list of source files you want to compile (defaults to \*.c \*.S) |
|
||||
| `CFALGS` | compiler flags you want to use (empty by default, like "-Wall -pedantic -std=c99") |
|
||||
| `LDFLAGS` | linker flags you want to use (I don't think you'll ever need this, just in case) |
|
||||
| `LIBS` | additional libraries you want to link with (like "-lm", only static .a libraries allowed) |
|
||||
| `USE_LLVM` | set this if you want LLVM Clang / Lld instead of GNU gcc / ld |
|
||||
| `ARCH` | the target architecture (only x86_64 supported for now, but the toolchain can handle multiple archs) |
|
||||
|
||||
Here's a more advanced **Makefile** example:
|
||||
```
|
||||
ARCH = x86_64
|
||||
TARGET = helloworld.efi
|
||||
SRCS = $(wildcard *.c)
|
||||
CFLAGS = -pedantic -Wall -Wextra -Werror --std=c11 -O2
|
||||
LDFLAGS =
|
||||
LIBS = -lm
|
||||
|
||||
USE_LLVM = 1
|
||||
include uefi/Makefile
|
||||
```
|
||||
|
||||
Accessing UEFI Services
|
||||
-----------------------
|
||||
|
||||
It is very likely that you want to call UEFI specific functions directly. For that, POSIX-UEFI specifies some globals
|
||||
in `uefi.h`:
|
||||
|
||||
| Global Variable | Description |
|
||||
|-----------------|----------------------------------------------------------|
|
||||
| `*BS` | *efi_boot_services_t*, pointer to the Boot Time Services |
|
||||
| `*RT` | *efi_runtime_t*, pointer to the Runtime Services |
|
||||
| `*ST` | *efi_system_table_t*, pointer to the UEFI System Table |
|
||||
| `IM` | *efi_handle_t* of your Loaded Image |
|
||||
|
||||
The EFI structures, enums, typedefs and defines are all converted to ANSI C standard POSIX style, for example
|
||||
BOOLEAN -> boolean_t, UINTN -> uintn_t, EFI_MEMORY_DESCRIPTOR -> efi_memory_descriptor_t, and of course
|
||||
EFI_BOOT_SERVICES -> efi_boot_services_t.
|
||||
|
||||
That header also provides an UEFI ABI wrapper, exactly the same as in gnu-efi, and functions to exit Boot Services
|
||||
and to dump memory for your convenience.
|
||||
|
||||
| Function | Description |
|
||||
|-----------------------|----------------------------------------------------|
|
||||
| `uefi_call_wrapper()` | call a function with UEFI ABI (provided by crt0) |
|
||||
| `uefi_exit_bs()` | leave this UEFI bullshit behind (provided by crt0) |
|
||||
| `uefi_dumpmem()` | dump memory (provided by libuefi.a) |
|
||||
|
||||
Unlike gnu-efi, POSIX-UEFI does not pollute your application with unused GUID variables. It only provides header definitions,
|
||||
so you must create each GUID instance if and when you need them.
|
||||
|
||||
Example:
|
||||
```c
|
||||
efi_guid_t gopGuid = EFI_GRAPHICS_OUTPUT_PROTOCOL_GUID;
|
||||
efi_gop_t *gop = NULL;
|
||||
|
||||
status = uefi_call_wrapper(BS->LocateProtocol, 3, &gopGuid, NULL, (void**)&gop);
|
||||
```
|
||||
|
||||
Also unlike gnu-efi, POSIX-UEFI does not provide standard EFI headers. It expects that you have installed those under
|
||||
/usr/include/efi from EDK II or gnu-efi with your distro's package management solution, and POSIX-UEFI makes it possible
|
||||
for you to use those system wide headers. POSIX-UEFI itself ships the very minimum set of typedefs and structs.
|
||||
```c
|
||||
#include <efi.h>
|
||||
#include <uefi.h> /* this will work as expected! Both POSIX-UEFI and EDK II / gnu-efi typedefs accessible */
|
||||
```
|
||||
|
||||
Notable Differences to POSIX libc
|
||||
---------------------------------
|
||||
|
||||
This library is nowhere near as complete as glibc or musl for example. It only provides the very basic libc functions
|
||||
for you, because simplicity was one of its main goals. It is the best to say this is just wrapper around the UEFI API,
|
||||
rather than a POSIX compatible libc.
|
||||
|
||||
All strings in the UEFI environment are stored with 16 bits wide characters. The library provides `wchar_t` type for that,
|
||||
so for example your main() is NOT like `main(int argc, char **argv)`, but `main(int argc, wchar_t **argv)` instead. All
|
||||
the other string related libc functions (like strlen() for example) use this wide character type too. Functions that supposed
|
||||
to handle characters in int type (like `getchar`, `putchar`), do not truncate to unsigned char, rather to wchar_t. For this
|
||||
reason, you must specify your string literals with `L""` and characters with `L''`. There's an additional `getchar_ifany`
|
||||
function, which does not block, but returns 0 when there's no key pressed.
|
||||
|
||||
That's about it, everything else is the same.
|
||||
|
||||
List of Provided POSIX Functions
|
||||
--------------------------------
|
||||
|
||||
### stdlib.h
|
||||
|
||||
| Function | Description |
|
||||
|---------------|----------------------------------------------------------------------------|
|
||||
| atoi | as usual, but accepts wide char strings and understands "0x" prefix |
|
||||
| atol | as usual, but accepts wide char strings and understands "0x" prefix |
|
||||
| strtol | as usual, but accepts wide char strings |
|
||||
| malloc | as usual |
|
||||
| calloc | as usual |
|
||||
| realloc | as usual (needs testing) |
|
||||
| free | as usual |
|
||||
| abort | as usual |
|
||||
| exit | as usual |
|
||||
| mbtowc | as usual (UTF-8 char to wchar_t) |
|
||||
| wctomb | as usual (wchar_t to UTF-8 char) |
|
||||
| mbstowcs | as usual (UTF-8 string to wchar_t string) |
|
||||
| wcstombs | as usual (wchar_t string to UTF-8 string) |
|
||||
|
||||
### stdio.h
|
||||
|
||||
| Function | Description |
|
||||
|---------------|----------------------------------------------------------------------------|
|
||||
| fopen | as usual, but accepts wide char strings, for mode L"r", L"w" and L"a" only |
|
||||
| fclose | as usual |
|
||||
| fflush | as usual |
|
||||
| fread | as usual, only real files accepted (no stdin) |
|
||||
| fwrite | as usual, only real files accepted (no stdout nor stderr) |
|
||||
| fseek | as usual, only real files accepted (no stdin, stdout, stderr) |
|
||||
| ftell | as usual, only real files accepted (no stdin, stdout, stderr) |
|
||||
| fprintf | as usual, but accepts wide char strings, max BUFSIZ, files, stdout, stderr |
|
||||
| printf | as usual, but accepts wide char strings, max BUFSIZ, stdout only |
|
||||
| sprintf | as usual, but accepts wide char strings, max BUFSIZ |
|
||||
| vfprintf | as usual, but accepts wide char strings, max BUFSIZ, files, stdout, stderr |
|
||||
| vprintf | as usual, but accepts wide char strings, max BUFSIZ |
|
||||
| vsprintf | as usual, but accepts wide char strings, max BUFSIZ |

|
||||
| vsnprintf | as usual, but accepts wide char strings |
|
||||
| getchar | as usual, waits for a key, blocking, stdin only (no redirects) |
|
||||
| getchar_ifany | non-blocking, returns 0 if there was no key press, UNICODE otherwise |
|
||||
| putchar | as usual, stdout only (no redirects) |
|
||||
|
||||
String formating is limited; only supports padding via number prefixes, `%d`, `%x`, `%X`, `%c`, `%s`, `%q` and
|
||||
`%p`. Because it operates on wchar_t, it also supports the non-standard `%C` (printing an UTF-8 character, needs
|
||||
char\*), `%S` (printing an UTF-8 string), `%Q` (printing an escaped UTF-8 string). These functions don't allocate
|
||||
memory, but in return the total length of the output string cannot be longer than BUFSIZ (8k), except for the
|
||||
variants which have a maxlen argument.

||||
