Type: Kernel Development

Description Link to heading

Added support for private threads in Linux kernel 3.17 for SMP (Symmetric Multi-Processing) systems, implementing thread-specific page tables with on-demand synchronization mechanisms.

Technologies Used Link to heading

• Linux kernel 3.17
• C kernel programming
• SMP (Symmetric Multi-Processing) systems
• Memory management subsystems
• Page table manipulation

Key Features Implemented Link to heading
