My recollection of the evening was that the exposing of per device qos latencies was not considered a good idea without better articulation on how it would be used. (or misused) FWIW a few folks (ok maybe just me) are not comfortable with exposing raw values without a good enough abstraction for them to user mode such that the values used through that user mode ABI would be somewhat portable between ISA's or even versions of the same chips / platforms. --mark > Regards, > Jean > > > > > > > - Paul > > _______________________________________________ > > linux-pm mailing list > > linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx > > https://lists.linux-foundation.org/mailman/listinfo/linux-pm > > > _______________________________________________ > linux-pm mailing list > linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx > https://lists.linux-foundation.org/mailman/listinfo/linux-pm _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
