在ARM系统调用 [英] System Call in ARM
问题描述
我看了一下系统在Linux中调用,到处都给出关于x86架构(ox80中断和SYSENTER)的描述。但我无法追查的文件和程序在ARM achitecture系统调用。任何人都可以请帮助。
I have read about system calls in Linux, and everywhere description is given regarding x86 architecture (ox80 interrupt and SYSENTER). But i am not able to track down the files and process for a system call in ARM achitecture. Can anyone please help.
我认识了一些相关的文件
Few relevant files which i got to know are
\\弓\\ ARM \\核心\\ calls.S
的\\弓\\ ARM \\核心\\入门common.S(解释需要)
\arch\arm\kernel\entry-common.S (explanation needed)
推荐答案
在ARM的世界里,您可以通过<$ C做了软件中断
(机制通知内核) $ C>超级用户调用/ SVC (previously称为SWI)。
In ARM world, you do a software interrupt
(mechanism to signal the kernel) by supervisor call / svc
(previously called SWI).
ARM汇编(UAL)的语法如下:
ARM assembly (UAL) syntax looks like this:
SVC{<c>}{<q>} {#}<imm>
(在Linux中,你需要通过#0)
(In Linux you need to pass #0)
您应该像<一个其他项目骗href=\"https://github.com/android/platform_bionic/blob/master/libc/arch-arm/syscalls/write.S\">bionic/write或 uClibc的样板。
