Kernel panic under high traffic load(mt7615-for-mt7621) #61

Closed cpktpoetkxwz closed 6 years ago

cpktpoetkxwz commented 6 years ago

Router: Phicomm K2P(mt7621 + one mt7615) Linux version: 4.14.37(OpenWrt trunk branch) Module: mt7615-for-mt7621-linux-4.14.34.ko I have extracted the "Factory" partition into /lib/firmware/mt7615.1.eeprom.bin, and copied both "mt7615-sku.dat" and "mt7615-sku-bf.dat" from stock firmware into /etc/wireless/mt7615.

Thanks for providing these drivers. The driver mt7615-for-mt7621 actually works like a charm! Mac addresses of interface ra0 and rax0 are correct. Both 5G and 2.4G signal are strong. WiFi latency is low.

But under relatively high traffic load, like doing 5G bandwidth testing with iperf, the driver or other process may cause kernel panic. It's kind of easy to reproduce, as it usually only takes two minutes of bandwidth testing(about 200Mbit/s) to cause kernel panic. Or maybe the trunk branch of OpenWrt is unstable under high traffic load? I'm not sure how to pinpoint the causes.....

Here is the content of one crashlog(from /sys/kernel/debug/crashlog). It shows iperf caused kernel panic, but I have no issue while doing bandwidth testing using ethernet. Also top showed ksoftirqd ate up a lot of resources before kernel panic, and the ksoftirqd used most of the resources was the one ra0 irq in.(I changed /proc/irq/$interrupt_number_of_ra0/smp_affinity to valid)

@Pentiumluyu Try run iperf c/s on wifi client, it's making no sense for wireless performance benchmark that runs it on the router, and it makes the stack more complex for debugging.

haswelliris commented 6 years ago

请问你的mt7615.1.eeprom.bin和mt7615-sku.dat是从哪里提取出来的。我试过用官方固件以及我刷过的openwrt15.05cc解包提取的都不行，用ifconfig -a 查看mac地址都是0 能给出您的详细步骤吗？

haoyixin commented 6 years ago

@haswelliris eeprom在factory分区中，sku在官方固件里，只改mac的话，eeprom 5-10 bytes就是，直接改就行 (一般情况)
