In order to maximize the portability of various drivers across platforms, we'll need to move to busdma as the means for setting up and managing dma transfers. However, since this hasn't been an area we have focussed on much in the past, it will probably take a little bit to get grounded and make sure all the infrastructure is in place. Could I get someone to volunteer to own the task of making whatever infrastructure improvements are necessary on alpha to support the busdma interface? This way we can avoid regressions in drivers that support dma natively on alpha, but don't use the busdma interfaces. Also, this will improve access to existing busdma drivers, such as the high performance crypto device drivers added by Sam Leffler, whichonly use DMA on busdma-enabled platforms. Thanks!

This is really just a first pass with a brief description, and some initial status. Status is split into two areas: platform support (i386, sparc64, etc), and driver support (network interfaces, storage, ...). For each, the level of support is in the process of being documented, and for drivers under active work, that is listed along with the task owner. Providing support for PAE on i386, as well as high performance driver support on non-i386 platforms, will require the conversion of many of the important system drivers. We'll need to inventory the relevant drivers, and then have maintainers update them to use the proper interfaces.
