Hello everyone, Yesterday I asked where board specific drivers should be located in the source tree. Several people suggested I just post the drivers for review right away, and let the reviewers comment on where to put the drivers.
Here they are. I've created a new drivers/fpga/carma/ directory for the drivers. I expect that this will not be their final resting place. The CARMA board is essentially an MPC8349EA MDS reference design with a 1GHz ADC and 4 high powered data processing FPGAs connected to the local bus. It is all packed into a compact PCI form factor. It is used at the Owens Valley Radio Observatory as the main component in the correlator system. For more information, see this webpage, maintained by the board's hardware engineer: http://www.mmarray.org/~dwh/carma_board/index.html These drivers are the necessary pieces to get the data processing FPGAs working and producing data. Despite the fact that the hardware is custom and we are the only users, I'd still like to get the drivers upstream. Several people have suggested that this is possible. Some further patches will be forthcoming. I have a driver for the LED subsystem and the PPS subsystem. The LED register layout is expected to change soon, so I won't post the driver until that is finished. The PPS driver will be posted seperately from this patch series; it is very generic. Thanks for any review and comments you can offer! Ira Ira W.
