Subject: resctrl: Relax the limit of maximum memory bandwidth allocation
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=d7e3a15a98d4e2cd550a9128a23337d893cb1c27;p=libvirt.git

resctrl: Relax the limit of maximum memory bandwidth allocation

The value 100 represented the percentage as it was originally done from
Intel in the Linux kernel and on their CPUs.  Since then the situation
changed and there is no error-prone way of figuring out the meaning of
the value in the current configuration, let alone its possible maximum.
