Load GDTR (Global Descriptor Table Register) from memory. [b] Yes 0 LIDT m16&32 [a] 0F 01 /3: Load IDTR (Interrupt Descriptor Table Register) from memory. [b] The IDTR controls not just the address/size of the IDT (interrupt Descriptor Table) in protected mode, but the IVT (Interrupt Vector Table) in real mode as well. LMSW r/m16: 0F 01 /6
A high-level overview of the Linux kernel's system call interface, which handles communication between its various components and the userspace. In computing, a system call (commonly abbreviated to syscall) is the programmatic way in which a computer program requests a service from the operating system [a] on which it is executed.
The system call interface of a kernel is the set of all implemented and available system calls in a kernel. In the Linux kernel, various subsystems, such as the Direct Rendering Manager (DRM), define their own system calls, all of which are part of the system call interface. Various issues with the organization of the Linux kernel system calls ...
This article describes the calling conventions used when programming x86 architecture microprocessors.. Calling conventions describe the interface of called code: The order in which atomic (scalar) parameters, or individual parts of a complex parameter, are allocated
A system call usually takes the form of a "system call vector", in which the desired system call is indicated with an index number. For instance, exit() might be system call number 1, and write() number 4. The system call vector is then used to find the desired kernel function for the request.
clone is a system call in the Linux kernel that creates a child process that may share parts of its execution context with the parent. Like FreeBSD's rfork and IRIX's sproc, Linux's clone was inspired by Plan 9's rfork and can be used to implement threads (though application programmers will typically use a higher-level interface such as ...
The man page for the sed utility, as seen in various Linux distributions. A man page (short for manual page) is a form of software documentation found on Unix and Unix-like operating systems. Topics covered include programs, system libraries, system calls, and sometimes local system details. The local host administrators can create and install ...
The set of the Linux kernel API that regards the interfaces exposed to user applications is fundamentally composed of UNIX and Linux-specific system calls. [201] A system call is an entry point into the Linux kernel. [202] For example, among the Linux-specific ones there is the family of the clone(2) system calls. [203]
