What is kernel driver?
Kernel drivers are programs written against Windows NT’s native API (rather than the Win32 Subsystem’s API) and which execute in kernel mode on the underlying hardware.
What is kernel vs driver?
In general, drivers provide detail implementation to specific physical or logical devices, while kernel then provide a set of interface for drivers, and manage them in a higher abstracted level (HAL). By the way, kernel does a lot more than managing hardware resources.
Is Windows Registry executed in kernel mode?
The Windows Registry was created to store data about hardware and software. The Windows kernel-mode configuration manager manages the registry. If your driver needs to know about changes in the registry, it can use the routines of the configuration manager to do so by registering callbacks on specific registry data.
What can a kernel driver do?
Kernel-mode drivers execute in kernel mode as part of the executive, which consists of kernel-mode operating system components that manage I/O, Plug and Play memory, processes and threads, security, and so on. Kernel-mode drivers are typically layered.
What does Lsmod do in Linux?
The lsmod command is used to display the status of modules in the Linux kernel. It results in a list of loaded modules. lsmod is a trivial program which nicely formats the contents of the /proc/modules , showing what kernel modules are currently loaded.
