[参考译文] SK-AM62：实时性能
你好：
想设置isolcpu=1-3，开发环境并没有选择yocto，需要在哪里进行设置。是需要修改cmdline么？
谢谢！
请问使用的是哪个软件版本？
使用的ti-processor-sdk-linux-rt-am62xx-evm-08.06.00.42的SDK中的内核和u-boot，尝试过在boot中在uEnv.txt中加入isolcpu=1-3，貌似并没有效果，查看PID 1还是部署在0-3核中。
已升级到英文e2e论坛，请看下面工程师的回复。Looking through the kernel documentation for K5.10, isolcpus is marked as deprecated, but it should still work in this release. Please try adding the following line to uEnv.txt:optargs='isolcpus=1-3'https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1255439/sk-am62-how-to-set-isolcpu
