Disable moal debug log

tanoue — Thu, 13 Apr 2023 09:09:32 GMT

Hi.

I would like to disable debug log in moal.ko and mlan.ko.

Debug logs are shown here.

[ 20.633064] wlan: SCAN COMPLETED: scanned AP count=42 # warning(4)
[ 20.754332] wlan: mlan0 START SCAN # alert(1)
[ 25.149396] wlan: SCAN COMPLETED: scanned AP count=43
[ 25.271133] wlan: mlan0 START SCAN
[ 29.617621] wlan: SCAN COMPLETED: scanned AP count=42
[ 31.514434] wlan: SCAN COMPLETED: scanned AP count=17
[ 31.536933] wlan: wfd0 START SCAN # alert(1)
[ 35.882825] wlan: SCAN COMPLETED: scanned AP count=36
[ 35.991569] wlan: wfd0 START SCAN
[ 40.337134] wlan: SCAN COMPLETED: scanned AP count=41
[ 40.345986] wlan: sched scan start
:

I read README in moal(kernel-module-nxp89xx) directory.

It lets me know that there are mlanctl for masking debug messages, but I didn't understand how to use it.

How all debug logs are disabled?

Best Regards.

Tanoue.

Hello @tanoue ,

I hope you are doing well.

->To disable the dmesg log please try to load the driver with the parameter drvdbg=0x00000000

Or one can load the driver but not give the drvdbg param along with other params.
It will disable all the logs.

EX:-

insmod mlan.ko && insmod moal.ko fw_name=nxp/<fw.bin> cfg80211_wext=0xf cal_data_cfg=none host_mlme=1

Thanks & Regards,

Hello @tanoue ,

I hope you are doing well.
I'm happy to help you.

->There is a standard drvdbg value that is recommended to use is 0x20037, no default value is there.
->One can set it as per their use case.
->One can check how to set the value of drvdbg in README.txt

As the issue is solved now, Can I Close this case?

Thanks & Regards,

Hi, @Sanket_Parekh

I understand the details of 0x20037 in according to README_WLAN.

mlanutl mlan0 drvdbg 0x20037 : Enable MMSG, MFATAL, MEEROR,
MCMND, MEVENT and MCMD_D messages

My "default" means to what message shown whih no drvdbg parameter.

It's answer was written in moal_init.c here.

#ifdef DEBUG_LEVEL1
#ifdef DEBUG_LEVEL2
#define DEFAULT_DEBUG_MASK (0xffffffff)
#else
#define DEFAULT_DEBUG_MASK (MMSG | MFATAL | MERROR | MREG_D)
#endif /* DEBUG_LEVEL2 */
t_u32 drvdbg = DEFAULT_DEBUG_MASK;

Best Regards.

Tanoue.
