GSoC 2025: In-Memory Filesystem for GPU Offloading Tests

[Arijit Kumar Das]

Hello GCC Community!

I am Arijit Kumar Das, a second-year engineering undergraduate from NIAMT
Ranchi, India. While my major isn’t Computer Science, my passion for system
programming, embedded systems, and operating systems has driven me toward
low-level development. Programming has always fascinated me—it’s like
painting with logic, where each block of code works in perfect
synchronization.

The project mentioned in the subject immediately caught my attention, as I
have been exploring the idea of a simple hobby OS for my Raspberry Pi Zero.
Implementing an in-memory filesystem would be an exciting learning
opportunity, closely aligning with my interests.

I have carefully read the project description and understand that the goal
is to modify *newlib* and the *run tools* to redirect system calls for file
I/O operations to a virtual, volatile filesystem in host memory, as the GPU
lacks its own filesystem. Please correct me if I’ve misunderstood any
aspect.

I have set up the GCC source tree and am currently browsing relevant files
in the *gcc/testsuite* directory. However, I am unsure *where the run tools
source files are located and how they interact with newlib system calls.*
Any guidance on this would be greatly appreciated so I can get started as
soon as possible!

Best regards,
Arijit Kumar Das.
