Subject: isolinux/rcS: Add 'test=cpu-low' and 'test=cpu-high' test-cases
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=8ca734b58f8308909f67e9d6e9454f36dae2f44d;p=xentesttools%2Fbootstrap.git

isolinux/rcS: Add 'test=cpu-low' and 'test=cpu-high' test-cases

The first will consume one CPU by spinning around and
doing md5sum of the memory. The later will do this on
all of the CPUs.
