Kernel Data StructuresDynamic Runtime ObjectsIn operating systems, we usually refer to a running instance of a data structure (data type) as an object. Locating runtime dynamic kernel objects in physical memory is the most difficult step towards enabling implementation of robust operating system ...
UNIX pioneered the hierarchical model of directories that contain files and/or other directories to allow the organization of data into a tree structure. Multiple file systems could be accessed by connecting them to empty directories in the root file system. In essence, this is much like grafting...
Kernel Configuration refers to the process of setting options and parameters in the operating system's kernel to control system behavior and capabilities, such as defining the number of simultaneous users the system can efficiently support. AI generated definition based on: Tru64 UNIX Troubleshooting,...
The kernel is critical to a computer's operation and requires careful protection within the system's memory. The kernel space it loads into is a protected area of memory. That protected memory space ensures other applications and data don't overwrite or impair the kernel, causing performance pro...
Using pid_t masks any possible difference in the actual data typing. We use the expression interface-specific to refer to a type defined by a library in order to provide an interface to a specific data structure. Note that, in recent times, relatively few new interface-specific types have ...
Both segment registers may be used as additional base registers in linear address calculations (in the addressing of local data and certain operating system data structures). 于是,Linux内核充分利用 FS 和 GS 寄存器的特性,将 GS 寄存器作为per-cpu变量寻址时的基址寄存器。
An IRP is a data structure that contains specific information used to convey the status of an event. For more information about the IRP data structure, see IRP and IRP Major Function Codes. Your driver can use System-Supplied Driver Interfaces to send IRPs to other drivers. In addition to ...
Driver support routines are routines that the Windows operating system provides for kernel-mode drivers to use. Drivers do not use Microsoft Win32 routines; instead, they use the driver support routines that this section describes. The driver support routines in this section are organized by kernel...
Just for grins, I looked into the implementation of the FLS functions. At offset 0xFB4 in the Thread Environment Block is a pointer to a data structure. Eight bytes into this structure is an array of 128 slots. These slots are conceptually the same as the TLS slots. As the thread switc...
To reduce the impact on the application, you can try to limit performance data collection to as few kernel functions and instances as makes sense for your analysis. See the filtering commands in the NVIDIA Nsight Compute CLI documentation. There is a relatively high one-time overhead for the ...
