Worked on the geerlingguy/linux repository to enhance AMDGPU driver reliability, focusing on VRAM state integrity and suspend-resume stability. Addressed a critical memory management issue by introducing a WARN_ON check to detect double-cleared memory during resource release or eviction, and implemented logic to reset the 'cleared' flag in the buddy allocator after system resume. These changes, developed in C with a focus on kernel development and device driver expertise, reduced the risk of VRAM corruption and improved system uptime for AMD GPU environments. The work emphasized disciplined commit practices and kernel-level debugging to deliver measurable improvements in production stability.
