我不是昇腾设备，没有安装驱动，是不是就没有__aicore__这个宏定义

在centos7，RTC支持参数wakealarm（/sys/class/rtc/rtc0/wakealarm），可设置定时开关机。但是鲲鹏的/sys/class/rtc/rtc0/下没有wakealarm参数，是否不支持？

【功能模块】图算融合，GPU (NVIDIA-RTX3080) 验证【操作步骤&问题现象】1、参考（基于mindspore0.5.0）链接1： https://gitee.com/mindspore/course/tree/master/06_distributed/graph_kernel2、参考（基于mindspore1.0.0）链接2： https://bbs.huaweicloud.com/forum/forum.php?mod=viewthread&tid=78817&page=1&replytype=13、按照教程和另一位大佬的帖子开启图算融合后，对基本组合算子和自组合算子进行试验，发现mindspore1.7.0生成的ir和.dot文件和之前版本的mindir文件的命名形式不一样，发现没有生成例子当中的文件（hwopt_d_fuse_basic_opt_end_graph_0.dot/hwopt_d_composite_opt_end_graph_0.dot）。未找到如下图红框中类似的图算融合后生成的ir/dot文件.minspore1.0.0生成的ir文件如下图（源自链接2楼主）请问是否有图算融合的整体流程图（细化到生成每个IR的小阶段）参考，多谢！【截图信息】本人基于mindspore1.7.0生成的mindir文件信息中，未找到图算融合后的.dot。烦请指导~多谢【日志信息】（可选，上传日志内容或者附件）
