Hi all,
we use an Intel Core i7 machine (64bit) to use the cores > 0 for real
time tasks.
For this the kernel boot parameter “isolcpus=1-31” is provided.
That works fine for all user space tasks.
However, I noticed that most kernel threads use the affinity mask 0xff.
I can change this by using “taskset”. However, I am wondering if there
is mechanism that forces the kernel to consider the value of “isolcpus”
also for kernel threads.
Kernel version in use is: 3.18.20-rt18.
Thanks for any feedback on this.
Best regards
Mathias
