Hey Alpha Folks,
Was wondering what the status of busdma support on Alpha is, in particular
regarding dmamap_load_mbuf(). 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!

Log:
Initial project page for driver busdma conversion. 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.
