Linux 7.3 kernel includes new hardware support, fixes, and improvements, including advisory non-fatal errors and Intel Dunlow support.

Why it matters

These updates improve the stability and functionality of the Linux kernel, especially for Intel processors and devices.

The Linux 7.3 kernel now lets devices signal some errors as 'advisory' instead of 'fatal'. This means the system can keep running even if a device has a problem, which helps keep things working smoothly.

Analysis

{"heading":"New Advisory Non-Fatal Errors Support","content":["The Linux 7.3 kernel now supports advisory non-fatal errors, a feature introduced in the PCI Express 7.0 specification. This allows for certain non-fatal errors to be signaled as advisory, which are masked by default and not reported under Linux until now.","This feature is particularly useful for hardware that can recover from errors without needing to halt the system. It helps in maintaining system stability and responsiveness.","The advisory non-fatal errors support is part of the PCI/PCIe subsystem updates for the in-development Linux 7.3 kernel."]}

Key points

  • Linux 7.3 includes new PCI/PCIe support and fixes.
  • Support for advisory non-fatal errors is added.
  • Intel Dunlow support is included for new devices.
The Upside

The advisory non-fatal errors support should help reduce the number of false alarms and improve the overall stability of the Linux kernel.

The Downside

If the advisory non-fatal errors are not handled correctly, they could lead to more hidden issues that might cause problems in the future.
