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
HP Spectre is a line of premium portable computers from HP Inc. (formerly Hewlett-Packard). Beginning as a high-end version of the HP Envy line in 2012, it became HP's flagship line of laptop products for consumers as of 2015.
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.
HP Universal Print Driver (UPD) is an intelligent print driver that supports a broad range of HP print devices, such as LaserJet and various MFPs. Developed by Hewlett-Packard , HP UPD combines a general purpose driver ( XPSDrv , UniDrv , or PSCRIPT ), print control, and HP proprietary extensions.
Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
The ME is supposed to detect that it has been tampered with and, if this is the case, shut down the PC forcibly 30 minutes after system start. [82] This prevents a compromised system from running undetected, yet allows the owner to fix the issue by flashing a valid version of the ME firmware during the grace period.
A simple form of envelope detector used in detectors for early radios is the diode detector.Its output approximates a voltage-shifted version of the input's upper envelope
