Kernel programming assembly language

Does Linux need Assembly?

There are some other features present in some processors (like paging) which need to be turned on from assembly as well. However
Most of the Linux kernel is written in C
Which interfaces with some platform specific C/assembly code through standardized interfaces.

How do kernels work?

Now i feel to do something interesting with kernels. A kernel resides between hardware and OS. It communicates with hardware using system calls. Every programming language require a compiler to compile the code written in high level language and then it generate low level code
Which is generally assembly language code.

What is assembly code in a kernel?

Assembly code in the kernel is generally used for low-level hardware interaction that can't be done directly from C. They're like a platform- specific foundation that's used by higher-level parts of the kernel that are written in C. The kernel source tree contains assembly code for a variety of systems.

What language is used in Linux kernel?

More precisely
The kernel is typically compiled with gcc [gcc] under -std=gnu11 [gcc-c-dialect-options]:
The GNU dialect of ISO C11. clang [clang] is also supported
See docs on Building Linux with Clang/LLVM. This dialect contains many extensions to the language [gnu-extensions]
And many of them are used within the kernel as a matter of course.

What is assembly language used for?

Second, it is widely used in the industry. Assembly language is used while designing operating systems and compilers. Of course, nowadays, a lot of this code is written in high-level languages like C, C++, etc. But certain parts of the kernel of the operating system are still written in assembly language.
