Device driver programming

I want to work one day as a device driver programmer, OS I'm in love is Solaris Smilie
I am learning C in my free time which I don't have because college took my life and I need to study to pass.
In college we work in C++ / Java. These languages aren't inteded for device driver programming , saying from my perspective.

I also read a solaris device driver development guide which is too advanced my knowledge, so is there some kind of book which tells how to start with system programming ?

I want to buy this book to start with system programming

DEVCTL(8)						    BSD System Manager's Manual 						 DEVCTL(8)

NAME
devctl -- device control utility SYNOPSIS
devctl attach device devctl detach [-f] device devctl disable [-f] device devctl enable device devctl suspend device devctl resume device devctl set driver [-f] device driver DESCRIPTION
The devctl utility adjusts the state of individual devices in the kernel's internal device hierarchy. Each invocation of devctl consists of a single command followed by command-specific arguments. Each command operates on a single device specified via the device argument. The device may be specified either as the name of an existing device or as a bus-specific address. More details on supported address formats can be found in devctl(3). The following commands are supported: attach device Force the kernel to re-probe the device. If a suitable driver is found, it is attached to the device. detach [-f] device Detach the device from its current device driver. If the -f flag is specified, the device driver will be detached even if the device is busy. disable [-f] device Disable a device. If the device is currently attached to a device driver, the device driver will be detached from the device, but the device will retain its current name. If the -f flag is specified, the device driver will be detached even if the device is busy. enable device Enable a device. The device will probe and attach if a suitable device driver is found. Note that this can re-enable a device dis- abled at boot time via a loader tunable. suspend device Suspend a device. This may include placing the device in a reduced power state. resume device Resume a suspended device to a fully working state. set driver [-f] device driver Force the device to use a device driver named driver. If the device is already attached to a device driver and the -f flag is speci- fied, the device will be detached from its current device driver before it is attached to the new device driver. If the device is already attached to a device driver and the -f flag is not specified, the device will not be changed. SEE ALSO
devctl(3), devinfo(8) HISTORY
The devctl utility first appeared in FreeBSD 11.0. BSD
February 5, 2015 BSD
