precompiled kernel modules (like exFAT)

imnuts · Feb 18, 2013

Can someone please tell me what they did to get precompiled kernel modules such as the exFAT modules provided by Samsung to load and work properly on the Note 2 kernels built from source? I've pulled in the commit that ignores the version info and also made a few other config changes so that the modules can load properly. However, if the kernel I build is used with an exFAT SDcard, the system will reboot as soon as Android goes to mount the card. I've tried using the modules from the VZW Note 2 (which I have) as well as the modules from the N7100, and both have the same end result.

A few more specifics and a kernel log would help...

The commonly used patch is the 1-liner excluding the exFat modules from module version check, but you say you already have that. Then you must have done some modifications in the kernel itself (SLUB/FTRACE?) to conflict with what the modules were built with.

I ran out of time to grab the logcat/dmesg today when I tried, I'll grab it after I get home from work. I added in FTRACE as the modules wouldn't load without them, which I found from trying to insmod them manually and looking at the resulting errors. I didn't change SLUB, which is what it had as default for VZW, and it is also the default for the config included in the source for the N7100. The source I'm building off of is here on Github and I'm using the arm-eabi-4.4.3 toolchain from JB AOSP to compile with, if those are any help.

FTRACE is something you should specifically leave disabled, I don't know why you actually enabled that. I'd also look into JRCU.

imnuts · Feb 19, 2013

I disabled FTRACE and recompiled, and am back to the same point I was at earlier with the modules not loading. I also removed JRCU, but this is the same issue I had without FTRACE added. Not sure why you think JRCU is part of the problem. Below is the error that I get when trying to insmod the exfat_core.ko module.

Code:

root@android:/ # lsmod
lsmod
vpnclient 90997 0 - Live 0x00000000
root@android:/ # insmod /lib/modules/exfat_core.ko
insmod /lib/modules/exfat_core.ko
insmod: init_module '/lib/modules/exfat_core.ko' failed (No such file or directo
ry)
255|root@android:/ # dmesg | grep exfat
dmesg | grep exfat

<4>[  337.999970] c3 exfat_core: Unknown symbol __gnu_mcount_nc (err 0)
root@android:/ #

So, I went back to what I have now with the modules at least loading. I formatted my card to exFAT and restarted to get a logcat and then pulled last_kmsg after. Here is logcat that was cleared shortly before inserting the exFAT SDcard

exFAT is a gray area in terms of licensing, etc. Because of that, I've made some edits to the OP to keep XDA out of legal trouble.

Instead of asking to get the exFAT module working with a custom kernel, the post will ask how to "get precompiled modules like exFAT working" - etc.

I asked you if you did SLUB changes, your SLQB patch alters/adds #include <linux/rcu_types.h> regardless if it is enabled in the config or not. Try reverting all your patches related memory management and RCU. Also unlike you, I run FTRACE disabled throughout all the kernels, enabling it will crash the device when loading the module for me.

imnuts · Feb 20, 2013

I reverted the RCU and SLQB commits, redid the config without FTRACE, and the modules aren't loading (still), and when I try to insmod them manually, I get the same error without the RCU/SLQB commits that I got with them.

Code:

Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation.  All rights reserved.

C:\Users\Mark>adb shell lsmod
vpnclient 90997 0 - Live 0x00000000

C:\Users\Mark>adb shell
root@android:/ # insmod /lib/modules/exfat_core.ko
insmod /lib/modules/exfat_core.ko
insmod: init_module '/lib/modules/exfat_core.ko' failed (No such file or directo
ry)
255|root@android:/ # dmesg | grep exfat
dmesg | grep exfat
<4>[   62.231113] c1 exfat_core: Unknown symbol kmem_cache_alloc_trace (err 0)
<4>[   62.231239] c1 exfat_core: Unknown symbol __gnu_mcount_nc (err 0)
root@android:/ #
C:\Users\Mark>

So, I went back, enabled FTRACE again with the RCU/SLQB commits out of the picture, and it cuts off at the same place on logcat as I posted above with JRCU/SLQB.

AndreiLux · Feb 20, 2013

Then I don't know. Diff my, or other kernel's defconfig. I've also heard some dev say a toolchain upgrade made it not possible anymore to load the modules, but didn't get the specifics on that.
