Log Message:
This is a preview of the uvm_hotplug(9) api code.
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
