I made a log file logsnd.log with requests to replay it with canplayer via candump. I got such kind of log: (1643028277.666468) can0 7F0#FF00 (1643028277.697728) can0 7F0#F40400005280D824 (1643028277.724488) can0 7F0#F40400005280D828...

With TX queue value 500, I recorded 6 files, only 2 of them were without data lost. I tried also to increase this value to 3000, 5000 and so on....

Can I verify current configuration for CPU by this command? `sudo cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor` Or which command would be proper? Running this, I get for each CPU(0,1,2,3) `ondemand`

I found a solution to make all CPU* run in performance mode, executing it in terminal: `sudo sh -c "echo -n performance> /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor"` then I check `cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor` and get...

So, when I enabled performance mode, I recorded 25 files. Only 13 of them are good, In other files, I see 1 or 2 frames missed. During logging of 5th,...

Seems, it becomes more stable, as earlier I saw more data missed. Error message looks like this: ``` Time Chn ID / Name Name DLC Data [-] 6750.803735 CAN 1...
