This commit does not actually introduce the UVM_HOTPLUG option. However it does provide developers a way to review, test and try out the API. To do this, please go to tests/sys/uvm/ and build and run the tests there. The tests also have a set of basic load tests, to get a measure of the performance penalties due to enabling the UVM_HOTPLUG option. In order to build the tests you need to have at least done the following in $SRC/ cd $SRC; $NBMAKE do-distrib-dirs includes cd $SRC/lib/csu; $NBMAKE all install || exit cd $SRC/external/gpl3/gcc/lib/libgcc/libgcc_s; $NBMAKE all install || exit cd $SRC/external/gpl3/gcc/lib/libgcc/libgcc; $NBMAKE all install || exit cd $SRC/lib/libc; $NBMAKE includes all install || exit cd $SRC/lib/libpthread; $NBMAKE all install || exit cd $SRC/lib/libm; $NBMAKE all install || exit cd $SRC/external/gpl3/gcc/lib/libstdc++-v3/; $NBMAKE all install || exit Once the development environment has these userspace libraries, one can simple build using $NBMAKE and finally test the kernel API using atf-run|atf-report
