OMG, you guys, I just learned the most lit thing about driver development and I HAVE to share!
So, I was trying to wrap my head around how drivers communicate with hardware, and I stumbled upon this crazy cool concept called "IRPs" (I/O Request Packs). Apparently, NTOSKRNL (the kernel) uses IRPs to manage I/O requests from applications and device drivers. Who knew?!
Like, for example, when you're trying to read data from a disk, the application sends an IRP to the disk driver, which then sends it to the disk controller. And the disk controller is like, "Hey, I got this!" It processes the request, and then sends the IRP back to the disk driver, which then sends it back to the application. Mind. Blown.
But here's the thing - IRPs can be used for more than just I/O requests. They can also be used for other types of requests, like power management or device setup. It's like, the kernel is all, "Hey, driver, can you handle this?" And the driver is like, "Yaaas, I got this!"
So, I'm just wondering... has anyone else out there worked with IRPs before? What are
