Ubuntu 25.10 “Questing Quokka” Arrives with Linux Kernel 6.17: Everything You Need to Know
Introduction: A New Era for Ubuntu Users
The Linux community has been buzzing with anticipation, and the wait is finally over. Ubuntu 25.10, codenamed “Questing Quokka,” has officially launched on October 9th, 2025, marking one of the most significant releases in Ubuntu’s history. This release represents not just an incremental update, but a fundamental shift in how Ubuntu approaches kernel development and user experience.
At the heart of this release lies Linux Kernel 6.17, a powerhouse of innovation that brings revolutionary features including the groundbreaking sched_ext scheduling system, enhanced gaming performance through the NTSYNC driver, and comprehensive support for the latest hardware from Intel, AMD, NVIDIA, and Qualcomm.
What Makes Linux Kernel 6.17 Revolutionary?
1. The Game-Changing sched_ext Scheduler
One of the most exciting additions in Linux Kernel 6.17 is the introduction of sched_ext (Extensible Scheduler), a revolutionary approach to process scheduling that changes everything we know about Linux performance optimization.
Sched_ext provides a mechanism to implement scheduling policies as eBPF (Extended Berkeley Packet Filter) programs. This means developers can now defer scheduling decisions to standard user-space programs and implement fully functional, hot-swappable Linux schedulers without modifying the kernel code.
Why does this matter? Traditional Linux schedulers are built into the kernel, making experimentation and customization extremely difficult. With sched_ext, you can:
- Experiment freely: Test new scheduling algorithms without kernel recompilation
- Hot-swap schedulers: Change scheduling policies on a running system without rebooting
- Optimize for specific workloads: Create custom schedulers for gaming, databases, or scientific computing
- Rapid development: Iterate on scheduling policies in days instead of months
2. NTSYNC Driver: A Gaming Revolution
Linux gaming just took a massive leap forward with the inclusion of the NTSYNC driver in Ubuntu 25.10. This driver emulates Windows NT synchronization primitives, delivering significantly better performance for Windows games running through Wine and Proton (Steam Play).
Performance Impact: Early benchmarks show performance improvements ranging from 5% to 40% in various Windows games, with the most dramatic gains seen in titles that heavily rely on synchronization primitives like mutexes and semaphores.
- Counter-Strike 2: 25-30% FPS improvement
- Cyberpunk 2077: 15-20% smoother frame pacing
- Red Dead Redemption 2: 10-15% reduced stuttering
- Baldur’s Gate 3: 20-35% faster loading times
3. Unconditional SMP Support
Kernel 6.17 introduces unconditional Symmetric Multi-Processing (SMP) support, meaning that multi-core and multi-processor systems now receive optimized treatment by default, without requiring special configuration. This results in:
- Better utilization of CPU cores across all workloads
- Improved responsiveness on systems with 8+ cores
- Enhanced performance in multi-threaded applications
- Reduced latency in cloud and virtualization environments
