Compiles, module loads but driver not working on Opensuse Tumbleweed Kernel 5.10.xx #31

Closed srihari83 closed 3 years ago

Hello, The master branch compiles on Opensuse Tumbleweed using the installation script without any error/warning messages to the console. Module is created & also loads but the driver has not been working since kernel upgrades starting from 5.10.1. Present kernel version at 5.10.7 & still fails. But make log shows many warnings.. these may be the cause. Have attached the make.log..

On the contrary, the old version of the driver 4.4.x on this link compiles, module loads & the driver works seamlessly. No particular error related to *.lds until now. Hope it helps.. Thanks a lot for the maintaining the repo until now!! clnhub_rtl8192eu_make.log

Hi,

There are no real issues in the (make) log file, just some smaller programming (style) warnings.

The default rtl8xxxu driver also doesn't work on openSUSE, while on Ubuntu it works @ about 1/10 of the normal speed.

Does it connect? Could you try debug mode and show the messages?

Hi, No, it doesn't connect. lsmod shows the module is loaded. Reloading after a depmod doesn't help.

I'm new to kernel/module debugging.. I tried the following: cd /sys/module/8192eu/sections cat .text .data .bss Output: 0xffffffffc137c000 0xffffffffc1472000 0xffffffffc149d380

Then I unzipped the module file 8192eu.ko.xz & started gdb gdb vmlinux /proc/kcore (gdb) add-symbol-file /lib/modules/5.10.7-1-default/kernel/drivers/net/wireless/8192eu.ko 0xffffffffc137c000 -s .data 0xffffffffc1472000 -s .bss 0xffffffffc149d380 add symbol table from file "/lib/modules/5.10.7-1-default/kernel/drivers/net/wireless/8192eu.ko" at .text_addr = 0xffffffffc137c000 .data_addr = 0xffffffffc1472000 .bss_addr = 0xffffffffc149d380 (y or n) y Reading symbols from /lib/modules/5.10.7-1-default/kernel/drivers/net/wireless/8192eu.ko... (No debugging symbols found in /lib/modules/5.10.7-1-default/kernel/drivers/net/wireless/8192eu.ko)

I don't know if what tried here is useless or wrong.. Please let me know!

In anycase, the output of hwinfo --usb shows: 07: USB 00.0: 0000 Unclassified device [Created at usb.122] . . Model: "D-Link Wireless N Nano USB Adapter" Hotplug: USB Vendor: usb 0x2001 "D-Link" Device: usb 0x3319 "Wireless N Nano USB Adapter" . . Driver Info #0: Driver Status: rtl8xxxu is not active Driver Activation Cmd: "modprobe rtl8xxxu" . .

I unloaded & reloaded the module in verbose. Output of modprobe -v 8192eu shows: insmod /lib/modules/5.10.7-1-default/kernel/drivers/net/wireless/8192eu.ko.xz

When I compile the older version 4.4.x from the Mange repo on this link, the make.log has no warnings. The module loads & the wifi works. Though the connection is a little slower. The output of hwinfo --usb with driver version 4.4.x shows:
