Environment
- Device: Tencent Aurora 4 Pro (S905X4-J)
- CoreELEC Version: CoreELEC-NG 21.x
- Current Kernel: Linux 4.9.269
- Requested Kernel: Linux 4.9.337
Request Overview
I propose upgrading the Linux kernel from 4.9.269 to the latest 4.9.337 LTS point release in the CoreELEC-NG branch for Amlogic S905X4-J devices. This is a standard, low-risk update that aligns with long-term support best practices.
Rationale
- Security Fixes: 4.9.337 includes backported security patches to mitigate known vulnerabilities in the 4.9 LTS kernel, enhancing overall system safety.
- Stability Improvements: Fixes for memory management, I/O scheduling, and media subsystem bugs will improve reliability during prolonged 4K/HDR/Dolby Vision playback, critical for media-center use cases.
- Compatibility: The update maintains the 4.9 vendor kernel branch required by Amlogic S905X4, ensuring full support for hardware decoding and all media features .
Use Case
My device (Tencent Aurora 4 Pro / S905X4-J) runs CoreELEC-NG daily for 4K HDR/DV playback. Upgrading to 4.9.337 will provide a more secure and stable foundation without breaking existing functionality.
Additional Notes
- I have verified no critical regressions are expected in this point release.
- The update is fully backward-compatible with the 4.9 series and does not require major code changes.
Thank you for your consideration. This update will benefit all S905X4-J users of CoreELEC-NG.
Best regards
