Unix Simulation Platform
|
|
|
|
|
========================
|
|
|
|
|
|
|
|
|
|
UnixPkg is one of platform package which can be built to a platform's firmware from UnixPkg.dsc file.
|
|
|
|
|
And this package provide a simulation platform under *INUX environment in IA32 architecture.
|
|
|
|
|
|
|
|
|
|
- Same points between real platform and simulation platform:
|
|
|
|
|
1) Unix simulation platform also run with firmware device image built from UnixPkg
|
|
|
|
|
2) The working flow of simulation platform also contains SEC/PEI/DXE phase.
|
|
|
|
|
|
|
|
|
|
- Different points between real platform and simulation platform:
|
|
|
|
|
1) The SEC phase in simulation platform in fact is a *INUX native application which can be run from *INUX shell;
|
|
|
|
|
2) The device in simulation platform is not real hardware but simulation component in API level;
|
|
|
|
|
3) The ThunkBus driver in simulation platform will get virtual device's desription from PCD and create virtual Device

Build
|
|
|
|
|
=====
|
|
|
|
|
UnixPkg is built with following command:
|
|
|
|
|
build -p UnixPkg/UnixPkg.dsc -a IA32 -t ELFGCC
|
|
|
|
|
Notes: ELFGCC is defined in <Workspace>/Conf/tools_def.txt file. This tool chain use native gcc/binutil instead of
|
|
|
|
|
cross-compiler like UNIXGCC tool chain.

|
On Mac OS X you can cd into UnixPkg directory and execute ./build.sh to build. This does not require
|
|
|
|
|
setting up the environment like running the build command. Note Snow Leopard or later is required.
|
|
|
|
|
This script should also work for any *INUX, but has not been tested.
|
|
|
|
|
|
|
|
|
|
./build.sh run will lanuch the emulator in gdb so you can source level debug via gdb.
|
|
|

|
|
|
|
|
|
Notes:
|
|
|
|
|
=====
|
|
|
|
|
On Mac OS X Snow Leopard you can use Xcode 3.2 as a GUI debugger.
|
|
|
|
|
Launch Xcode and open UnixPkg/Xcode/xcode_project/xcode_project.xcodeproj
|
|
|
|
|
Under the build menu chose build and debug. shift-cmd-B shows the build results.
|
|
|
|
|
|
|
|
|
|
Under most *INUX the EFI executables are placed in the emulated EFI memory by the EFI PE/COFF loader
|
|
|
|
|
but dlopen() is used to also load the image into the process to support source level debug.
|
|
|
|
|
The entry point for the image is moved from the EFI emulator memory into the dlopen() image. This
|
|
|
|
|
is not the case for Mac OS X. On Mac OS X a debugger script is used and the real EFI images in
|
|
|
|
|
the emulator are the ones being debugged.
|
|
|
|
|
|
|
|
|
|
Also on Mac OS X the stack alignment requirements for IA-32 are 16 bytes and this is more strict
|
|
|
|
|
than the EFI ABI. To work around this gasket code was introduced to ensure the stack is always
|
|
|
|
|
16 byte aligned when making any POSIX call on Mac OS X.
|
|
|
|
|
|
|
|
|
|
To build PE/COFF images with Xcode 3.2 and extra tool call mtoc is required to convert Mach-O
|
|
|
|
|
images into PE/COFF images. The tool only supports EFI PE/COFF images and the instructions on
|
|
|
|
|
how to download it are on the edk2 website.

FAQ
|
|
|
|
|
===
|
|
|
|
|
1, I fail to build UnixPkg due to "X11/extensions/XShm.h: No such file or directory"?
|
|
|
|
|
The display adapter in UnixPkg is a virtual device written in X11 API. The library of x11proto-xext-dev is required
|
|
|
|
|
for building.
|
|
|
|
|
|
|
|
|
|
2, I fail to build UnixPkg due to "/usr/bin/ld: cannot find -lXext"?
|
|
|
|
|
libxext-dev library is required for building.
|
