# Makefile for the bktr Brooktree Bt848/Bt878 PCI video capture device
# Using the new FreeBSD 4.x device driver API (newbus) the Bt848 driver
# can be loaded dynamically both in the boot loader phase and once
# the system has booted.
# The driver can also be unloaded, recompiled and reloaded.
#
# Use kldload bktr   and kldunload bktr  to load/unload the driver
#
# Note - as the driver requires contiguous memory, loading the driver once
# memory has filled or become fragmented may fail.
