+barebox Project Ideas
+#####################
+
+This section collects ideas to improve barebox and should serve as a pool
+of ideas for people who want to enter the field of firmware development
+but need some guidance what to work on.
+
+These tasks can be adopted as part of programs like Google Summer of Code
+or by motivated individuals outside such programs.
+
+If you find a project interesting and would like to work on it, reach out
+to the :ref:`mailing list <feedback>` and we can together
+try to figure out whether you are a good match for the project.
+
+For GSoC, following barebox developers are mentoring:
+
+ - Ahmad Fatoum (IRC: ``a3f``)
+ - Sascha Hauer (IRC: ``_sha_``)
+ - Rouven Czerwinski (IRC: ``Emantor``)
+
+This list can be edited and extended by sending patches to the mailing list.
+Other interesting ideas: Support for new file systems (EROFS, extfat, btrfs),
+improvements for barebox-efi (e.g. as a coreboot payload), ... etc.
+
+Ideas listed below should contain a title, description, expected outcomes,
+skills (and HW if any) required and a difficulty rating.
+Projects are meant to be about 175 hours of effort, unless otherwise noted.
+
+Address static analyzer feedback for barebox
+============================================
+
+Skills: C. Difficulty: Lowest
+
+barebox is automatically tested using Synopsys' free "Coverity Scan" service.
+The static analyzer has so far identified 191 possible defects at
+https://scan.coverity.com/projects/barebox
+
+There is a number of false positives there, but it already helped us
+find actual regressions, e.g. 610720857348 ("fs: ext4: fix bogus behavior
+on failure to read ext4 block").
+
+To make this service more useful, the project would involve categorizing
+reported issues and handling them as appropriate: Mark them as not applicable
+if false positive or provide patches to fix real issues.
+
+Expected outcome is that barebox is coverity-clean.
+
+This project does not require dedicated hardware. QEMU or barebox built
+to run under Linux (sandbox) may be used.
+
+Update barebox networking stack for IPv6 support
+================================================
+
+Skills: C, Networking. Difficulty: Medium
+
+The barebox network stack is mainly used for TFTP and NFSv3 (over UDP) boot.
+Most embedded systems barebox runs on aren't deployed to IPv6 networks yet,
+so it's the right time now to future-proof and learn more about networking
+internals. One major complication with IPv6 support is neighbor discovery
+protocols that require networking to be possible "in the background".
+barebox' recent improvements of resource sharing and cooperative scheduling
+makes it possible to integrate an IPv6 stack, e.g. lwIP.
+
+There are also community patches to integrate a TCP stack into barebox.
+These can be evaluated as time allows.
+
+Expected outcome is that barebox can TFTP/NFS boot over IPv6.
+
+This project does not require dedicated hardware. QEMU or barebox built
+to run under Linux (sandbox) may be used.
+
+Improving barebox test coverage
+===============================
+
+Skills: C. Difficulty: Lowest
+
+barebox is normally tested end-to-end as part of a deployed system.
+More selftests/emulated tests would reduce the round trip time for testing
+and thus enable more widely tested patches. A framework has been recently
+merged to enable this:
+
+ * Selftest similar to the kernel can be registered and run. These
+ directly interface with C-Code.
+ * Labgrid tests: These boot barebox in a virtual machine or on real
+ hardware and use the shell to test barebox behaviors.
+
+This project will focus on improving the testing coverage by writing more
+tests for barebox functionality and by fuzzing the parsers available in
+barebox, with special consideration to the FIT parser, which is used in
+secure booting setups.
+
+Expected outcome is a richer test suite for barebox and an automated
+setup for fuzzing security-critical parsers.
+
+This project does not require dedicated hardware. QEMU or barebox built
+to run under Linux (sandbox) may be used.
+
+Porting barebox to new hardware
+===============================
+
+Skills: C, low-level affinity. Difficulty: Medium
+
+While Linux and Linux userspace can be quite generic with respect to the
+hardware it runs on, the bucket needs to stop somewhere: barebox needs
+detailed knowledge of the hardware to initialize it and to pass this
+along information to Linux. In this project, familiarity with barebox
+and a new unsupported SoC will be established with the goal of porting
+barebox to run on it. Prospective developers can suggest suitable
+hardware (boards/SoCs) they are interested in. Preference is for
+hardware, which is generally available and has more open documentation.
+
+The goal is to have enough support to run barebox on the board, set up
+RAM and load a kernel from non-volatile storage and boot it.
+
+If time allows (because most drivers are already available in barebox),
+new drivers can be ported to enable not only running Linux on the board,
+but bareDOOM as well.
+
+Expected outcome is upstreamed barebox drivers and board support to
+enable running on previously unsupported hardware.
+
+This project requires embedded hardware with preferably an ARM SoC, as
+these have the widest barebox support, but other architectures are ok
+as well.
+
+Improve barebox RISC-V support
+==============================
+
+Skills: C, RISC-V interest, low-level affinity. Difficulty: Medium
+
+barebox supports a number of both soft and hardRISC-V targets,
+e.g.: BeagleV, HiFive, LiteX and the QEMU/TinyEMU Virt machine.
+
+Unlike e.g. ARM and MIPS, RISC-V support is still in its formative
+stage, so much opportunity in implementing the gritty details:
+
+ - Physical memory protection in M-Mode to trap access violations
+ - MMU support in S-Mode to trap access violations
+ - Improve barebox support for multiple harts (hardware threads)
+
+Expected outcome is better RISC-V support: Access violations are
+trapped in both S- and M-Mode. Virtual memory is implemented and
+Linux can be booted on multiple harts.
+
+This project does not require dedicated hardware. QEMU can be used.
+
+Improve barebox I/O performance
+===============================
+
+Skills: C, low-level affinity. Difficulty: Medium
+
+On a normal modern system, booting may involve mounting and traversing
+a file system, which employs caching for directory entries and sits
+on top of a block device which caches blocks previously read from the
+hardware driver, often by means of DMA. There are a number of improvements
+possible to increase throughput of barebox I/O:
+
+ - More efficient erase: Communication protocols like Android Fastboot
+ encode large blocks of zeros specially. MMCs with erase-to-zero
+ capability could perform such erases in the background instead
+ of having to write big chunks of zeros.
+ - Block layer block sizes: There is a fixed block size used for
+ caching, which is meant to be a good compromise for read
+ and write performance. This may not be optimal for all devices
+ and can be revisited.
+
+Expected outcome is faster read/write/erasure of MMC block devices.
+
+This project requires embedded hardware with SD/eMMC that is supported
+by a barebox media card interface (MCI) driver.
+
+Improve JSBarebox, the barebox web demo
+=======================================
+
+Skills: C (Basics), Javascript/Web-assembly, Browser-Profiling. Difficulty: Medium
+
+While Linux and Linux userspace can be quite generic with respect to the
+hardware it runs on, the bucket needs to stop somewhere: barebox needs
+detailed knowledge of the hardware to initialize it and to pass this
+along information to Linux. JSBarebox removes the hurdle of porting
+barebox to a new board, for new users who are only interested in
+trying it out: The browser runs Tinyemu, a virtual machine in which
+barebox executes as if on real hardware and the user can manipulate the
+(virtual) hardware from the barebox shell and learn about barebox
+conveniences: barebox.org/demo/
+
+The project is about streamlining this demo: CPU usage currently is
+quite high and teaching barebox to idle the CPU (as we do on sandbox)
+didn't help. This needs to be analyzed with the profiling tools
+provided with modern browsers. The remainder of the project can then
+focus on improving the tutorial inside the demo. e.g. by adding new
+peripherals to the virtual machine.
+
+Expected outcome is snappier and less CPU-intensive barebox demo.
+TinyEMU is extended, so the RISC-V machine is more like real
+hardware and tutorial is extended to make use of the new pripherals.
+
+This project does not require dedicated hardware. The development
+machine need only support a recent browser.
