摘要： A device driver includes a kernel mode and a user-mode module. The device driver may access device registers while operating in user-mode to promote system stability while providing a low-latency software response from the system upon interrupts. The device driver may include kernel stubs that are loaded into the operating system, and may be device specific code written. The stubs may be called by a reflector to handle exceptions caught by the stubs. A reset stub may be invoked by the reflector when the user-mode module or host terminates abruptly or detects an interrupt storm. The reset stub may also be invoked if errant direct memory access DMA operations are being performed by a hardware device. The reset stub may ensure that hardware immediately stops unfinished DMA from further transfer, and may be called by the user-mode driver module.

摘要： A computer configured to operate in diagnostic mode during which the operating system is suspended. During the diagnostic mode, tests can be performed on the computer system, including hardware, and the tests do not disrupt the operating system and are not disrupted by the operating system. When diagnostic mode is triggered, execution of the operating system is suspended. When the diagnostic tests are completed, the operating system may resume operation and test data may be made available within the operating system environment. Upon resuming, the state of the computer prior to entering diagnostic mode may be restored, preventing any changes made during diagnostic mode from interfering with operation of the operating system or application components.

摘要： A system, methodology and/or computer architecture that facilitates processing device interrupts (including level-triggered interrupts) in a user-mode process is provided. The kernel interrupt handler can cause a dedicated thread in the process to wake and invoke the driver interrupt service routine. This thread can then return control to the kernel interrupt handler. In addition to processing interrupts in an isolated mode, the context switching technique could be used in any isolated environment to process interrupts via dedicated execution context methods.

摘要： A device driver includes a kernel stub and a user-mode module. The device driver may access device registers while operating in user-mode to promote system stability while providing a low-latency software response from the system upon interrupts. Upon receipt of an interrupt, the kernel stub may run an interrupt service routine and write information to shared memory. Control is passed to the user-mode module by a reflector. The user-mode module may then read the information from the shared memory to continue servicing the interrupt.

摘要： When multiple contacts are detected for a phone number of an incoming call, a notification that multiple contacts matched the phone number is displayed. When the display area for displaying the notification is adequate to display a full list of the contacts that correspond to the phone number of the incoming call, the full list is displayed. When the display area is inadequate to display the full list, a scrollable list of the multiple contacts is displayed. Alternatively, when the display area is inadequate, a multiple contacts message is displayed that notifies a user that multiple stored contacts matched the phone number of the incoming phone call.

摘要： A device driver includes a hypervisor stub and a virtual machine driver module. The device driver may access device registers while operating within a virtual machine to promote system stability while providing a low-latency software response from the system upon interrupts. Upon receipt of an interrupt, the hypervisor stub may run an interrupt service routine and write information to shared memory. Control is passed to the virtual machine driver module by a reflector. The virtual machine driver module may then read the information from the shared memory to continue servicing the interrupt.

摘要： A system that facilitates the storage of data using a write barrier. The system interfaces to a hardware component that stores data, and includes a write barrier component that dynamically employs instructions compatible with the hardware component to ensure data integrity during storage of the data. The write barrier component is independent of at least an operating system and an application and can operate in a least one of a user mode and a kernel mode. The write barrier component includes at least one of software instructions, routines, and methods, the selection of one or more of which is based on hardware data extracted from the hardware component. A selection component interrogates the hardware component for hardware data to facilitate selection of one or more instructions most suitable for interfacing to the hardware component. A coalescing component combines cache synchronization requests into a single set of instructions, which set is processed to flush a disk cache in one process.
