Difference between System call and VDSO

System call vs. VDSO

In computing, a system call (commonly abbreviated to syscall) is the programmatic way in which a computer program requests a service from the operating system on which it is executed. vDSO (virtual dynamic shared object) is a kernel mechanism for exporting a carefully selected set of kernel space routines to user space applications so that applications can call these kernel space routines in-process, without incurring the performance penalty of a mode switch from user mode to kernel mode that is inherent when calling these same kernel space routines by means of the system call interface.

Application binary interface

In computer software, an application binary interface (ABI) is an interface between two binary program modules.

C standard library

The C standard library or libc is the standard library for the C programming language, as specified in the ISO C standard.

Context switch

In computing, a context switch is the process of storing the state of a process or thread, so that it can be restored and resume execution at a later point, and then restoring a different, previously saved, state.

IA-32

IA-32 (short for "Intel Architecture, 32-bit", commonly called i386) is the 32-bit version of the x86 instruction set architecture, designed by Intel and first implemented in the 80386 microprocessor in 1985.

Protection ring

In computer science, hierarchical protection domains, often called protection rings, are mechanisms to protect data and functionality from faults (by improving fault tolerance) and malicious behavior (by providing computer security).

User space and kernel space

A modern computer operating system usually uses virtual memory to provide separate address spaces, or separate regions of a single address space, called user space and kernel space.
