Security researchers have discovered four critical vulnerabilities in the firmware of hundreds of Gigabyte motherboards that ...

The UEFI firmware in more than 240 GIGABYTE motherboards carries four high‑severity vulnerabilities (CVE‑2025‑7026 through ...

In “ Handler Migration and Direct Interrupt Scheduling,” Jupyung Lee and Kyu Ho Park of the Korea Advanced Institute of Science and Technology describe two techniques to minimize the scheduling ...

Using interrupts means that your main loop gets to do other things, effectively letting you run different kinds of tasks in the background.

For example, a serial port might issue an interrupt request when a new character arrives. The processor responds to the request by transferring control to an interrupt handler or interrupt service ...

MAGA influencers are warning that discontent among members of President Donald Trump's base over the handling of the Jeffrey ...

This handler should acknowledge the interrupt; it usually does not need to do anything else. The mmap (), open (), and release () functions are called from the equivalent file_operations members.

The interrupt handler is completely automated as it waits for the interrupt event. After receiving interrupt, it executes ISR and clears the status registers after few cycles.

And finally, we can set up the microcontroller’s interrupt handler to trigger when the line goes high, and write an ISR to handle the new data when it does. (The initialization and ISR ...
