Driver Verifier is a tool included in Microsoft Windows that replaces the default operating system subroutines with ones that are specifically developed to catch device driver bugs. [1] Once enabled, it monitors and stresses drivers to detect illegal function calls or actions that may be causing system corruption.
A new user-mode driver model called the User-Mode Driver Framework. In Windows Vista, WDDM display drivers have two components, a kernel mode driver (KMD) that is very streamlined, and a user-mode driver that does most of the intense computations. With this model, most of the code is moved out of kernel mode.
The 64-bit versions of Vista require that all new Kernel-Mode device drivers be digitally signed, so that the creator of the driver can be identified. [ 77 ] [ 78 ] This is also on par with one of the primary goals of Vista to move code out of kernel-mode into user-mode drivers, with another example bing the new Windows Display Driver Model .
Windows Vista, an operating system released by Microsoft for consumers on January 30, 2007, has been widely criticized by reviewers and users. Due to issues with new security features, performance, driver support and product activation, it has been the subject of a number of negative assessments by various groups.
The early development stages of Longhorn were generally characterized by incremental improvements and updates to Windows XP.During this period, Microsoft was fairly quiet about what was being worked on, as their marketing and public relations focus were more strongly focused on Windows XP, and Windows Server 2003, which was released in April 2003.
In Windows XP, drivers account for 85% of the reported failures. In the Linux kernel 2.4.1 device driver code accounts for about 70% of the code size. [2] The driver fault can crash the whole system as it is running in the kernel mode. These findings resulted in various methodologies and techniques for verification of device drivers.
Network device drivers for Windows XP use NDIS 5.x and may work with subsequent Windows operating systems, but for performance reasons network device drivers should implement NDIS 6.0 or higher. [8] Similarly, WDDM is the driver model for Windows Vista and up, which replaces XPDM used in graphics drivers.
The Windows Vista Bluetooth stack supports a kernel mode device driver interface besides the user-mode programming interface, which enables third parties to add support for additional Bluetooth Profiles such as SCO, SDP, and L2CAP. This was lacking in the Windows XP Service Pack 2 built-in Bluetooth stack, which had to be entirely replaced by a ...
