HiSilicon Kunpeng 920 (ARM64 server chip) has SPE feature and we are working on this to enable it with more perf support: https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg2067868.html Thanks Hanjun _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel ^ permalink raw reply [flat|nested] 4+ messages in thread
