How to go about .....

I assume you have had a look at the Device Driver tutorial at http://docs.sun.com/app/docs/doc/817-5789 ?

I would start by writing a dummy driver that loads and unloads.

Then maybe add character entry points, and read and write some kernel memory (see kmem_alloc/free and uiomove)

Then look at adding block entry points - look at physio, strategy.

Then it's a case of what device do you want to control, and looking at mapping device registers and doing dma.

The Solaris driver framework is designed to be architecture independant. So in principle Intel/Amd drivers are no different to SPARC. Just remember for AMD when compiling to use:

cc -c -D_KERNEL -xarch=amd64 -xmodel=kernel

otherwise you'll get relocation errors on the console when you try loading.

Can give some more specific questions?

Cheers,

Ralph
