Google Summer of Code 2018¶
Replicant intends to apply to GSoC 2018 as part of the FSF umbrella. This page lists suggested projects for GSoC students. This list is a draft!
Advance the Optimus Black U-Boot and Linux mainline ports¶
The Optimus Black is an interesting potential target for Replicant, since it has the ability to use a free bootloader. Paul did some initial work on getting U-Boot and mainline Linux running on it, which would lay the groundwork for a future Replicant port. You can help by picking up where Paul left off, and getting U-Boot and mainline Linux running on the Optimus Black.

Advance the Kindle Fire first generation U-Boot and Linux mainline ports¶

Access Point mode for RepWifi¶
RepWifi is Replicant's app for using an external USB WiFi adapter. RepWifi is useful for Replicant because there exist USB WiFi adapters with free firmware, while the built-in WiFi chipsets in mobile phones do not have free firmware. Right now, RepWifi doesn't support acting as an access point (e.g. for WiFi tethering purposes); you can help by adding this functionality to RepWifi.

Port Replicant to a newer LineageOS version¶

OS Updater¶
It would be useful for a Replicant device to be able to update itself to a new version of Replicant without requiring being connected to a PC. You can help by implementing this functionality. LineageOS already supports this; we suspect that it should be possible to adapt this LineageOS functionality to Replicant.

Implement a fully-featured QMI-RIL¶

Implement the missing features of Samsung-RIL¶
Samsung-RIL is the RIL (Radio Interface Layer) that many Replicant devices use to communicate with the modem. It is a free, reverse-engineered replacement for the proprietary RIL that the Samsung phones ship with by default (which has been found to have backdoors). Right now, Samsung-RIL mostly implements only the protocol features that are absolutely necessary for the phone to be operable. As a result, many more rarely used protocol features are unimplemented, which decreases functionality compared to the proprietary RIL. You can help by implementing the missing features of Samsung-RIL.

Debug metallic sound in many 3G calls¶
Replicant has been observed to sometimes exhibit a metallic sound quality when doing voice calls over 3G (2G works fine). This is problematic, since most users prefer to stay in 3G mode (and some carriers are dropping support for 2G). You can help by debugging the issue.

Optimize power consumption in external WiFi adapter firmware¶
The USB WiFi adapters used with Replicant are originally intended for laptops, not phones. As a result, they tend to consume a lot of power. This poses two issues: they can adversely impact battery life, and they can randomly stop working completely (e.g. needing to unplug and replug the adapter periodically to keep it operational). You can help by optimizing power consumption in the WiFi adapter firmware.

Projects mentored by other organizations¶
llvmpipe ARM optimizations¶
(Project description: TODO; can probably be adapted from https://redmine.replicant.us/projects/replicant/wiki/GraphicsResearch#llvmpipe .)
Difficulty: TODO
Requirements/Prerequisites: TODO
Expected Outcomes/Deliverables: TODO
Mesa would probably be a good organization for mentoring this project. If interested in working on this project, please propose it to Mesa. (We're happy to help.)
