Hi Greg,
This contains first a whole bunch of fixes to the existing vme code in staging, to then introduce a new driver model for VME in patch 27.
I have a short list of things to do after this patchset gets reviewed:
- provide a saner API for VME drivers that just want to map/unmap chunks of memory (knowing nothing about underlying hardware features, such as windows). This is already implemented in the out-of-tree driver in [1].
- Make DMA work on the tsi148 (it's the only bridge I've got). This will probably involve changing or extending the current API.
- Test the whole thing with real hardware and a real VME driver (currently out of tree as well, see [2]), which I'll try to get merged, too--currently we just have vme_user.c which really isn't a kosher driver.
Note that the appended applies on top of linux-next.
The patchset can be pulled from: git://github.com/cota/linux-2.6.git vme-next
Thanks,
Emilio
