原标题:Implementation of system calls / traps within Linux kernel source

目前,我正在学习操作系统,利用陷阱促进在含水层圈内的系统电话。 我把陷阱的陷阱列表放在了前面,c 以及许多陷阱在入口处的实施。 S.

然而,我奉命在利用陷阱实施系统呼吁的欧伦特掩体中找到两个系统。 虽然我可以找到这些陷阱的定义,但我不敢肯定,这些陷阱之一的“召唤”会看什么。 因此,我竭力寻找这一行为的例子。

Before anyone asks, yes, this is homework.

As a note, I m using Github to browse the kernel source, since kernel.org is down: https://github.com/torvalds/linux/

问题回答

在x86结构中,只有32个轨道舱位<>。 可在<代码>/x86/include/asm/irq_vectors.上看到打断的病媒布局。 http://www.un.org/Depts/DGACM/index_french.htm

<代码>_system_get_gate (SYSCALL_VECTOR, &system_quest);

<64bit kernels, the new SYSENTER<> (Intel) or SYSCALL (AMD) intructions are used for exercise grounds. www.un.org/Depts/DGACM/index_french.htm 建立“手稿”的定义,编号为enter_64.S,名称相同(system_et)。

关于用户空间,您不妨对查询。 页: 1

如果你重新寻找实际的系统电话,而不是执行系统电话,你可能要检查一些C图书馆。 为什么要把一个系统称作一个ker? (如果不谈论system calls implementation,我谈论的是实际的chdir 例如呼吁。 有一个<代码>chdir<>>>>>>> 系统电话<>em>,要求修改名录,并有一个<代码>chdir<>> 系统电话执行<>>,该编码实际上必须加以修改,而且必须在纸浆中有所改动。 Ok, 也许有些掩体也含有一些动脉,但又是另一个故事:

不管怎么说,如果我回答问题,你不要指望执行,而是实际呼吁。 对我来说,全球营养联盟的校准太复杂,但你可以尝试浏览饮食平衡来源。 一些实例:

chdir.S

sys callss.h
