No software in the world is flawless and flawless, which highlights the importance of using tools to discover or FIX software deficiencies, bugs, and even major vulnerability errors. Based on this idea, the new version of Linux2.6.26 kernel should be pregnant. Linux personnel are provided with an independent kernel debugger to help improve this open-source operating system.

The new version of Linux2.6.26 continues the relentless update and improvement cycle of the Linux kernel. The new features and improved driver support greatly enhance the performance of this open-source operating system.

GeraldPfeifer, director of Novell inbound productmanagement, told InternetNews.com that "kgdb support for kernel debugger (kerneldebug) is the most surprising change. This proves to be useful in solving some hard support problems ."

It is understood that KGDB is the new Linux source code level kernel debugging tool, so it is very convenient to debug the kernel at the source code level, the disadvantage is that kgdb can only perform remote debugging, it requires a serial line and two machines to debug the kernel (or run two operating systems on the same host using vmware software ). Torvalds, the founder of Linux, once opposed the tool. Eight years ago, he wrote in LinuxKernelMailingList, "I don't like debugging tools. I did not like it in the past, nor will I like it in the future! There is no need to use the kernel debugger. People should consider solving problems in the development process at different levels ."

Although Torvalds is still the leader in the release of major Linux systems, there are not many kernel developers who prefer KGDB. A recent survey by the Linux Foundation shows that more than 100 kernel developers in more than 1000 companies prefer KGDB. Congratulations to the famous red hat company Linux, RikvanRiel, Senior Software Engineer, told InternetNews.com, "for me, the KGDB debugging tool is crucial for the improvement of Linux2.6.26. The PageAttributeTable (page Attribute Table, PAT for short) features provide excellent support for video card products.

Compared with the kernel 2.6.25 of the previous version, 2.6.26 provides wider driver support and performance improvement. For example, support for x86PAT; read-only "Bindmounts"; PCIExpress dynamic power management; KVM support for IA64, PPC, and S390 architectures; new UVC camera driver; Support for OLPC; draft support for 802.11s networks; multiple File Systems, including EXT4, and kgdb support for kerneldebug.
