Qi Yadong 4c8c7cc8d1 trusty: initialize tsc_offset to zero ... Per trusty design, trusty requires a monotonic increasing secure tick(TSC) at run time. This secure tick will used to mitigate password/pin force attack, control key expiration, etc. Currently, the TSC_OFFSET is enabled. And guest will got (host_tsc + tsc_offset) when execute rdtsc/rdtscp/rdmsr to aquire tsc value. The host_tsc is always keeping increasing during the runtime. So initialize tsc_offset of trusty to 0 will ensure the secure tick feature. Signed-off-by: Qi Yadong <yadong.qi@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>		2018-04-09 12:37:02 +08:00
