Hi Shirley,
> Do you know if the PF_NO_SETAFFINITY flag can help in any way?
AFAIK, this will not work for kernel thread.
For example, with 4.8.13-1 kernel:
Display all kernel threads with
ps aux | grep "\["n
(as kernel threads are enclosed in square brackets, [ ])
And pick one of them and try:
Fix segment fault when detach a device due to some redundant function
call in ice_dev_uninit.

Hi Rami,
This is correct but that is because the default value of the PF_NO_SETAFFINITY
flags does not allow to set affinity to kernel threads from user space.
I was looking for a way to change the kernel and recompile it to be able to
block kernel threads from running on the cpu isolated cores. (s
Perhaps by modifying the function set_cpus_allowed() which sets the kernel
threads flag with PF_NO_SETAFFINITY.
To remark it in the kernel code and to recompile the code.

Hi Shirley,
Hi,
It could be that this will work, but as I assume you know -
This requires providing a patched kernel to end customers, some will not
like it, some

- It could be that a kernel patch to the Kernel Mailing list for enabling
such functionality (globally or pe
Hi,
I will consider that.
Thanks again for your help.

The flow isolated mode lacks some advertisement in the docs,
especially in association with flow bifurcation.
There was also a miss in flow bifurcation howto for Mellanox case.
Thomas Monjalon (3):
doc: remove useless anchor for flow API guide
doc: add references to flow isolated mode in NICs
In the howto guide about flow bifurcation, the Mellanox case
(which does not require specific details) was missing in the landscape.
In the Linux drivers guide, it was not clear that the flow bifurcation
is performed in the NIC hardware.
References to flow isolated mode are also inserted in those
A doc page (.rst file) can be referenced with :doc: syntax
instead of :ref: to .. anchor.
