Board specific macro definition Refer to [Documentation/arm/Porting] Decompressor Symbols Macro name description example ZTEXTADDR [arch/arm/boot/compressed/Makefile] Start address of decompressor. There's no point in talking about virtual or physical addresses here, since the MMU will be off at t...
Sigset_t in x/sys/unix is defined as follows for amd64: type Sigset_t struct { Val [16]uint64 } In total, it has space for 1024 signals. However, Linux syscalls expect a sigset_t like so: #define _NSIG 64 #define _NSIG_BPW 64 #define _NS...

your attempt. The way around this problem is to tell the compiler that the structure must be “packed,” with no fillers added. For example, the kernel header file<linux/edd.h>defines several data structures used in interfacing with the x86 BIOS, and it includes the following definition: ...
The Linux kernel is a monolithic kernel that's constantly growing; it had 20 million lines of code in 2018. From a foundational level, it's layered into a variety of subsystems. These main groups include a system call interface, process management, network stack, memory management, virtual ...
在使用Linux外部源代码编译PetaLinux工程时,遇到错误“.kernel-meta/bsp_definition: Directory nonexistent”。执行“petalinux-build -x mrproper -f”清理PetaLinux工程,并且在Linux外部源代码目录执行“make mrpr...
Let’s look at this definition in the kernel source: You have our dummy example: a simple function that is defined as apostcoreinitcall. Thepostcore_initcalldefinition is calling the__define_initcall()with its ID: 2. The__define_initcall(fn, id)is calling anotherdefine_initcall()with an ad...
This is a short document describing the preferred coding style for the linux kernel. Coding style is very personal, and I won'tforcemy views on anybody, but this is what goes for anything that I have to be able to maintain, and I'd prefer it for most other things too. Please at leas...
Linux kernel release 4.x <http://kernel.org/> These are the release notes for Linux version 4. Read them carefully, as they tell you what this is all about, explain how to install the kernel, and what to do if something goes wrong. WHAT IS LINUX? Linux is a clone of the operating...
