Hi all, I was curious about the following doubts: 1. In presence of multiple devices, whether multiple instances of the driver (which drives the device) will be created?
i believe not. if the device is of plug 'n' play type, a probe function inside the driver is called when a new device is inserted and the rest is upto it. kernel makes no separate instances of the driver. if the device is not plug 'n' play, you have to manually detect and configure the device and required data structures while loading the driver.
2. If so, then whether multiple instances of a global variable defined in the driver module will be created? In this case, whether there is any dependency upon static qualifier for that global variable?
