if 1 and 2 are successfull shouldn't we have a bus driver for the in-kernel i2c subsystem that uses the dsm methods? Those way both kernel clients for it, or userspace programs through /dev/i2c* could access it? (and yes, someone would have to write that code, but maybe Brian would be interested in that) _______________________________________________ Linux-nvdimm mailing list [email protected] https://lists.01.org/mailman/listinfo/linux-nvdimm
