X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4ee91aadeee48f57b0988ecb63eb526064bbb180;p=thirdparty%2Fkernel%2Flinux.git

accel/amdxdna: Set the system efficiency factor to 2

The system efficiency factor is used for QoS calculation. Change it to 2
to account for the efficiency overhead.
