HelloIommuPkg
==============
HelloIommuPkg is a sample DXE runtime driver demonstrating how to program DMA
remapping, one of the Intel VT-d features, to protect the system from DMA access.
This project is meant to show a simplified yet functioning code example for learning
purposes and not designed for actual use in production systems.
For more information about this project see my blog post: [Introductory Study of IOMMU (VT-d) and Kernel DMA Protection on Intel Processors](https://standa-note.blogspot.com/2020/05/introductory-study-of-iommu-vt-d-and.html)
Building
---------
1. Set up edk2 build environment
- `bb18fb80abb9d35d01be5d693086a9ed4b9d65b5` is the latest revision that confirmed to compile this project successfully .
2. Copy `HelloIommuPkg` as `edk2\HelloIommuPkg`
3. On the edk2 build command prompt, run the below command:
```
> edksetup.bat
> build -t VS2019 -a X64 -b NOOPT -p HelloIommuPkg\HelloIommuPkg.dsc
or
> build -t CLANGPDB -a X64 -b NOOPT -p HelloIommuPkg\HelloIommuPkg.dsc
```
Or on WSL or Linux,
```
$ . edksetup.sh
$ build -t GCC5 -a X64 -b NOOPT -p HelloIommuPkg/HelloIommuPkg.dsc
```
Also, pre-compiled binary files are available at the Release page.
