Hi, i try to write an device driver for Accelerometer in the Thinkpad T series. There is an Linux driver already which i ported to FreeBSD.
So far i got a working version which returns some useful information. What i want to know is which is the correct way to allocate io ports? I saw some drivers using "bus_alloc_resource" and some use "bus_space_map". What is the safest way to read/write to an io port? Simply "inb/outb" or "bus_space_write_N/bus_space_read_N" ? Any help would be appreciated Thanks Maik _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
