Developed and integrated a Linux kernel sysfs platform driver in the shweatank/Mirafra_LDD3 repository, enabling controlled userspace interaction through a newly exposed 'foo' attribute with read and write access. The work involved implementing the driver in C, registering it as a platform driver, and creating a corresponding platform device to support testing and future extensibility. As part of ongoing maintenance, the previous Sysfs_july10 implementation was deprecated and removed, streamlining the codebase for easier long-term support. This effort demonstrated proficiency in device drivers, Linux kernel development, and sysfs, with a focus on maintainability and clean repository management practices.
