Tasks
These tasks have been identified by our community. They are currently open for development by community members, and would be a great way to get involved and start contributing. Please let us know on edk2-devel if you plan to work on one of these tasks (to prevent duplicated effort). Also, please provide status updates on edk2-devel so the community will know the project is still being actively developed.
LLVM support in EDK II is currently limited to Linux builds. Add build support under Microsoft Windows 10.

Enable Coverity Scan for all EDK II projects. https://scan.coverity.com/
- Evaluate open source CI tools to fine best one to periodically auto run Coverity static analysis
- Look into ways to auto-post results to TianoCore (website, wiki, or git repo).
- Look into ways to automate Bugzilla issue generation based on Coverity results.
Allow APs to safely print and use DEBUG trace messages.
> Note: This project depends on an open-source MP implementation, which is currently not available.

Intel Firmware Engine adds UserExtensions in the SDK to describe connections between modules and module parameters (as "Patchable In Binary" PCDs). This enables binary distribution of configurable firmware components. Porting these extensions to a branch of OVMF would allow development and testing of these concepts on a virtual platform.

- https://firmware.intel.com/sites/default/files/Intel%C2%AE%20Firmware%20Engine%20SDK_R2.0.2.zip
Simplify EDK II development:
- GUI helper tool to pull multiple repos and setup WORKSPACE.
- GUI helper tool to configure and launch a build.
- GUI helper tool to configure platform PCDs.
- GUI helper tool to configure FLASH layout, Recovery, and Capsules.
- Use Intel Firmware Engine user extensions to perform additional build checking.
- Automatically set values in target.txt based on platform configuration (compiler, thread count, etc.).
On demand builds to verify patch series before sending to edk2-devel (for Windows, Linux, OSX)

The DataHub and GCD layers don't scale well as the number of data items gets large, since they are based on simple linked lists. Find better data structures.

Make use of __builtin_return_address(n) & _ReturnAddress to add debug & data gathering capabilities. Some ideas:
- Produce a protocol with info on the image handle so a shell command can dump out the information
- Track, on a per call basis, where resources are being consumed
- Detect memory leaks
- Log information about stall and timer usage
- Collect statistics on BootServices and RuntimeServices calls.
- Performance profile library calls EFI boot and runtime services calls.
- gBS is set up by a library so it could point to a debug wrapper for the functions.
- Post process raw output (PDB name + offset in PE/COFF) to include function names via parsing .map files.
Note: There are many ideas here. Please feel free to gather any reasonable subset for a project proposal.
- Debug version of libraries, and tools to analyze the data:
- UefiBootServicesTableLib.h & UefiRuntimeServicesLib.h that can profile UEFI service usage.
- Debug version of MemoryAllocationLib.h that can detect memory leaks, buffer overruns, etc.
- Add a library class for logging the data
- Log data directly to image handle, per driver.
- Log data to centralized data service.
- Add a library class for a module to access/initiate leak checking.
- Add sample based profiling to EmulatorPkg/Nt32Pkg. On a Mac this would be figuring out how to use Instruments to profile the emulator.
- Add a sampling based profiling tool to a real EFI system. Note this requires the ability to capture a stack trace and then post process it (likely on the build system).

A CSM allows a UEFI system to boot legacy operating systems on IA32 & X64 systems. In other words, most current production OS's. Strong preference is for a BSD licensed solution, as this is license used by nearly all of our code. A SeaBIOS based solution could be considered, but would not be as widely usable (GPL license). http://www.coreboot.org/SeaBIOS
- Difficulty: Hard
- Language: Assembly, C
- Mentor:
- Suggested by: bjjohnson
- Status: No longer a priority, since UEFI OS support is mainstream. SeaBIOS can be built as a CSM, but a BSD licensed alternative is still not available.
