If a user application passes a function pointer to kernel mode code, and the kernel mode code calls the function pointer directly, then the thread is STILL in kernel mode (remember it is still a property of the thread, just not so obviously) while executing user mode code. And that is ...

Device drivers are also classified as kernel or user. A kernel mode device driver is a generic driver that's loaded along with the OS. These drivers are often suited to small categories of major hardware devices, such as CPU andmotherboarddevice drivers. User mode device drivers encompass an ...
The new stack includes drivers that are loaded by Windows when a USB 3.0 device is attached to an xHCI host controller. The new drivers are based on Kernel Mode Driver Framework (KMDF) and implement features defined in the USB 3.0 specification. The new drivers are as follows: Usbxhci.sys...

Certain instructions (privileged instructions) could be executed only when the CPU is in kernel mode. If any attempt is made to execute a Privileged Instruction in User Mode, then it will not be executed and treated as an illegal instruction. The Hardware traps it to the Operating System. ...
Thesos reportcommand is a tool that collects configuration details, system information and diagnostic information from a Red Hat Enterprise Linux system. For instance: the running kernel version, loaded modules, and system and service configuration files. The command also runs external programs to coll...
What is kernel-level programming in an OS? Kernel-level programming involves writing software that interacts directly with the operating system's core functions (the kernel). This type of programming requires specialized knowledge and can be used to create device drivers, security software, and other...

Containerizationis an approach to software development that isolates processes that share an OS kernel -- unlike virtual machines (VMs), which require their own -- and binds application libraries and dependencies into one deployable unit. This makes containers lightweight to run, as they require on...
