Week-14 @RTEMS-GSoC-2025

Overview

This week, I completed the following tasks :

• Work on GRETH RX Mechanism

Work completed this week

1. Completing RX mechanism
   • This week and till end of submission deadline, I worked on ensuring the RX mechanism of the driver works successfully.
   • After experimenting with several ideas, I observed that the best way to implement RX mechanism is to have the function greth_rx_pbuf_refill() refills exactly a single pbuf. This comes with an advantage, that whenever the pbuf is freed, a single pbuf is freed, so that we can dereference a pbuf chain of a single pbuf.
   • However I fell seriously ill during this period, due to which I faced a bit of a lag in my work But, I was able to ensure RX and TX (Non-GBit) worked.
   • I cleaned up the code and created the final MR which can be found here
2. Creating documentation
   • During this period, I also worked on creating elaborate documentation for this project.
   • The documentation can be found here
