In the last years, FLUSP members have been dedicating time and effort to contribute with FLOSS projects. In this section, we describe for a set of FLOSS projects what we achieved so far:

Linux Kernel:

  • The group accounted for 20% of all contributions made to the IIO subsystem in the period from 10/03/2018 to 11/17/2018.

  • From 01/04/2019 to 04/04/2019, the percentage of contributions made by FLUSP members to the IIO subsystem was 19.4%, almost the same percentage of 2018.
  • There are approximately 115 patches made by FLUSP members in the main tree of the Linux Kernel.
  • Three drivers containing FLUSP contributions were moved from staging one driver in the DRM subsystem.
  • One of our members is the maintainer of the VKMS, which is a driver in the DRM subsystem.
  • Due to FLUSP’s efforts in contributing to drivers in the IIO subsystem, a company donated more them four hardware boards. An explanation of each one of the boards together with useful links (such as the datasheets) can be found at the resources.


  • One FLUSP member is working in the Git version-control system. This member submitted seven patches to the official repository.
  • The FLUSP member who contributes with Git also applied for GSoC’2019. The project proposal is to make the Git codebase more thread-safe, such that in the future it will be possible to improve Git’s parallelism.
  • The FLUSP members also gave classes on Git to the freshmen of the Institute of Mathematics and Statistics (IME-USP).


  • There is one FLUSP member actively working on the GNU Compiler Collection (GCC). This member has already three patches accepted, and 11 submissions made. He also applied to GSoC’19 with a GCC project related to parallelize part of the compilation.
