BIT is a macro defined in include/linux/bitops.h in the kernel tree: #define BIT(nr) (1UL << (nr)) So BIT(10) is basically an unsigned long with tenth bit set.
Is my Linux 32 or 64-bit?
To know whether your system is 32-bit or 64-bit, type the command “uname -m” and press “Enter”. This displays only the machine hardware name. It shows if your system is running 32-bit (i686 or i386) or 64-bit(x86_64).
Is Linux 64-bit only?
While most new PCs come with 64-bit architecture, Linux isn’t only used on modern hardware. Many people use Linux to breathe life back into older machines. For that reason, many distributions provide both 32-bit and 64-bit versions for download.

What is AMD64 bit?
AMD64 is a 64-bit processor architecture that was developed by Advanced Micro Devices (AMD) to add 64-bit computing capabilities to the x86 architecture. AMD64 is backward compatible, which is highly beneficial in the real world because it means that 64-bit applications can coexist with 16-bit and 32-bit applications.
What is the difference between aarch64 and x86_64?
x86_64 is name of specific 64-bit ISA. This instruction set was released in 1999 by AMD (Advanced Micro Devices). AMD later rebranded it to amd64. Other 64-bit ISA different from x86_64 is IA-64 (released by Intel in 1999).
Is 32-bit dead?
While some of us are still clinging onto our favorite 8-bit microprocessors, ARM announced they will be killing off the 32-bit architecture in 2022 and/or 2023.

What is 32-bit Linux kernel?
32-bit operating systems generally consume less space on the hard disk, in addition to using fewer resources, especially RAM. And although 32-bit systems are limited to a maximum of 4 GB of RAM, the Linux Kernel can ignore this limit if we use a Kernel PAE.
Which Linux distros are 32-bit?
Luckily, there are still many Linux distros that bet on compatibility and continue to offer users ISO images to use them on 32-bit systems without problems. 32-bit Linux distros Debian. Luckily, although Ubuntu no longer supports 32-bit, Debian does. And, as we know, Debian is the base on which Ubuntu is built.
