Why is there not a simple interface to it? I'd suggest something like: void * xxx_alloc_mem(u_int32_t size, u_int8_t align_power); u_int32_t xxx_vtophys(void *ptr, u_int32_t size); void xxx_free_mem(void *ptr, u_int32_t size); Yours -HPS _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
