LS1046A 10G Network performance

JSKIM — Thu, 24 Dec 2020 14:52:18 GMT

I have tested 10G Performance with lsdk2004. I have looked issue related 10G network test. and i figure out that there need disable kernel options to test which are CONFIG_CPU_FREQ and CONFIG_NETFILTER.

In my case, it is similar to below issue case. i know that the issue is cleared.

May i have the reason why disable CONFIG_CPU_FREQ option caused the issue that fman-port failed? is there any other kernel option with disable CONFIG_CPU_FREQ ?

[the issue]
the kernel disable option which is CONFIG_CPU_FREQ cause t all fman-port failed during POST.

I didn't find any problem when building Linux Kernel with CONFIG_CPU_FREQ and CONFIG_NETFILTER disabled in LSDK2004.

I attached my Kernel configuration file and Linux kernel booting up console log to you.

I uploaded my Kernel image in the following link, you could try it on your target board.

Thank for your response.

I find out there is no kernel option in my case which is CONFIG_CLK_QORIQ.

After applied the option, it's fixed the problem.

Wishing you a year full of blessing.
