Ciao!
How are you?
I found there is this setting CONFIG_KERNEL_DEBUG_FS=y
, but with make menuconfig
(the new OpenWRT
), I cannot un-check. Do you know that is?
Isn't slowing down the router and use more memory?
Thanks,
Patrik

The other debugging options I was able to un-check.
try to change in your .config
file change CONFIG_KERNEL_DEBUG_FS=y
to # CONFIG_KERNEL_DEBUG_FS is not set
then run make defconfig
and check that it's still unset
or another option is to open make menuconfig
press /
then search for KERNEL_DEBUG_FS
and that should show up how it's defined and where in the menuconfig
hey @commodo !
how are you?
So if I just comment out this debug fs, it will not give problems right? That's it?
Thanks so much,
Patrik
What is weird is, that you can only change the .config
, in the make menuconfig
, there is no option, it is always checked, no option to un-check
. Weird. Would be good to know why it is done like this.

not quite ; if there is a symbol that enforces the selection of CONFIG_KERNEL_DEBUG_FS=y
then you cannot disable it ;
if you do grep -r KERNEL_DEBUG_FS | grep select
you will find out which symbols select [and enforce] KERNEL_DEBUG_FS
seems you may need to disable also: [CONFIG_]PACKAGE_MAC80211_DEBUGFS
and/or [CONFIG_]KERNEL_DYNAMIC_DEBUG
From the print-screen it looks like KERNEL_DYNAMIC_DEBUG - "Compile the kernel with dynamic printk" is disabled.
So, likely [CONFIG_]PACKAGE_MAC80211_DEBUGFS
thanks so much!
it looks like this:
docker@49593bd9842a:/build/source$ grep -r KERNEL_DEBUG_FS | grep select
package/kernel/mac80211/Makefile: select KERNEL_DEBUG_FS
config/Config-kernel.in: select KERNEL_DEBUG_FS
tmp/.packageinfo: select KERNEL_DEBUG_FS
tmp/info/.packageinfo-kernel_mac80211: select KERNEL_DEBUG_FS
tmp/.config-package.in: select KERNEL_DEBUG_FS
docker@49593bd9842a:/build/source$
So, I guess, it is better to keep it, can't be so slowing so much the router, right?
Thanks Master!
tbh, I don't know about any slow-down effects of KERNEL_DEBUG_FS
;
some investigation would be needed to see about it;
i suspect there are sources for slow-down that have a higher impact than this
yeah, i think so.
thanks so much! take care! ciao!
