we want the ISOLATE the CPU for LS2088 CPU -0 for kernel 1-7 for application.
we tried to set the BOOT parameter but its resetting when rebooted. could you let us know how to set the same . we are using SD board method for LSDK 18.09.
Hello Ranganatha YN,
Please add "isolcpus=1-7" in bootargs, then run "saveenv" to save bootargs in SD card.
The parameter "isolcpus" insures that Linux Kernel doesn't use these CPUs for scheduling its tasks - that prevents context switching of any application running on these cores.
we try to execute the same setps when we booted from SD:
=> run bootcmd
Once the kernel boots cat /proc/cmdline -is not displaying the isolCPU. do we need to set the
Please add "isolcpus=1-7" in bootargs in u-boot , for example
=>setenv bootargs "console=ttyS0,115200 root=/dev/mmcblk1p4 rw rootwait earlycon=uart8250,mmio,0x21c050 isolcpus=1-7"
