Lots of tips

I just finished re-writing a cctv utility that does the whole ptz thing. The first cut was a trivial C utility. I built a C++ architecture that does the same thing, but it does it reliably. It is also very extensible, maintainable, flexible, self documenting, supplemented with srs and design docs, and is specialized at three levels to provide a solid foundation.

So, the first thing that I did was to set up a couple libraries. The first one is just a grab bag of basic tools. The second, a set of parameterized classes that provide stream specializations. These not only can work on every platform (with necessary specializations), but can be adapted to different types of com devices. The third library set up an abstract architecture to facilitate stream interactions. The final utility is a specialization of the abstract architecture, and defines specifically how to interact with the target device.

So, all of the generic work is handled using generic stuff. All the specializations are handled in the user code.

AMDTEMP(4)						   BSD Kernel Interfaces Manual 						AMDTEMP(4)

NAME

     amdtemp -- device driver for AMD K8, K10 and K11 on-die digital thermal sensor

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   device amdtemp

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   amdtemp_load="YES"

DESCRIPTION

     The amdtemp driver provides support for the on-die digital thermal sensor present in AMD K8, K10 and K11 processors.

     For the K8 family, the amdtemp driver reports each cores' temperature through a sysctl node in the corresponding CPU devices's sysctl tree,
     named dev.amdtemp.%d.sensor{0,1}.core{0,1}.  The driver also creates dev.cpu.%d.temperature displaying the maximum temperature of the two
     sensors located in each CPU core.

     For the K10 and K11 families, the driver creates dev.cpu.%d.temperature with the temperature of each core.

BUGS

     AMD K9 is not supported because temperature reporting has been replaced by Maltese.

SEE ALSO

     sysctl(8)

HISTORY

     The amdtemp driver first appeared in FreeBSD 7.1.
