 07 Dec 2007 7:47 Interaction Device Driver and Kernel |
|

|
Hi,
I have a question that I can't really have a strong answer to convince myself.
Question:
1. Is Device Driver a Subset of Kernel ? or both are sitting in the same hierarchy ?
2. When Developing a Board Support Package for a new board, how's the kernel going to affect the device driver?
3. Why is a Linux BSP Device Drivers not compatible with VxWorks BSP Device Drivers?
4. Says I mount a USB Thumb Drive to a Embedded Linux Based System, how's is the embedded software's execution flow?
Please help the confused one.

This depends on the kernel but most drivers sit on a higher abstraction level than the core kernel.

The kernel will define it's interface to the driver. As the driver just abstracts between the hardware and the kernel the kernel interface is a major factor in driver design.

Because of the different kernel interfaces
