Do you know that Linux kernel-supported system calls and features are architecture dependent? Let’s take a look at the process to get insight into supported system calls and features and to assess how secure a system is and its runtime activity.

Let’s first define what static and runtime system states are, and then explore how we can visualize the static and runtime system parts of the kernel. Static System View comprises system calls, features, static and dynamic modules enabled in the kernel configuration.

Linux kernel tool https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/scripts/get_feat.pl can be used to list the Kernel feature support matrix for an architecture.
