A cudaEventt is a marker that can be dropped into a stream and later queried, waited on, or used to measure elapsed time between two points — it's the mechanism behind both accurate kernel timing and dependencies between streams that don't require the host to get involved. Both uses matter here: naive host-clock timing of GPU work produces numbers that look plausible and are wrong, and coordinating streams without a host round-trip is what makes the concurrency from Streams and Concurrency composable into a real pipeline. See Error Handling and Checking for what CUDACHECK does with the status these calls return.

Almost everything on a microcontroller is the vendor's. The timers, the UARTs, the clock tree, the GPIO blocks — all of it is ST's design, at ST's addresses, described in ST's reference manual, and none of it transfers to a part from a different vendor. A handful of peripherals are not like that. They are Arm's, they are built into the processor itself, they sit at the same addresses on every Cortex-M ever made, and code that uses them ports between vendors without changes.
