LAN7430 driver needs patching - fix included

[mangodan2003]

Describe the bug
lan743x module fails to map DMA here https://github.com/raspberrypi/linux/blob/rpi-5.10.y/drivers/net/ethernet/microchip/lan743x_main.c#L1986

To reproduce
Using the CM4IO board along with the LAN7430 evaluation board (PCIe) build and load the lan743x module.

Expected behaviour
Should work

Actual behaviour
Module init fails (note I added some debug printk's)

can confirm this bug, EVB-LAN7430 is not recognized correctly and needs fixing.
Unfortunately i'm too dumb to compile the kernel correctly and thus can't confirm the fix.

[6by9]

The lan743x driver is unmodified from mainline so any real bugs ought to be reported upstream and fixed there.

That said, the patch feels like the default mask is incorrect as I wouldn't have expected individual drivers to need patching like this. @pelwell may know what those defaults will be/how it is initialised.

LPAE extensions do confuse matters significantly between 32 and 64 bit systems though. Does it work on the 64bit kernel?

[6by9]

Then again there appear to be a number of drivers that do manually set the dma mask

Tried with Ubuntu Server ARM (uname -a -> Linux ubuntu 5.4.0-1028-raspi #31-Ubuntu SMP PREEMPT Wed Jan 20 11:30:45 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux), not working either.

Last I tried to boot a 64Bit kernel it hung waiting for the root device and I haven't tried again since. I will so so when I get a spare moment.

[mangodan2003]

I've now tested 5.10.17 64bit. Doesn't work out of the box. Works with the above fix applied.

[aep]

patch works for me with 5.10.27-v8+

[gnijieb]

Any updates on this issue? Is the above fix deemed good enough to be used in production?

Backporting all the lan743x changes from mainline to the rpi-5.10.y branch did not fix the issue.

Can confirm the issue and the fix.

As @6by9 rightly said:

Hello,

I ' ve used this driver on my RPI kernel version:

root@raspberrypi:~# uname -a
Linux raspberrypi 5.10.17-v7l+ #1403 SMP Mon Feb 22 11:33:35 GMT 2021 armv7l GNU/Linux

And it's works !

But, when I 've tried to another RPI, with another kernel version:

raspberrypi:/home/pi# uname -a
Linux raspberrypi 5.15.32-v7l+ #1538 SMP Thu Mar 31 19:39:41 BST 2022 armv7l GNU/Linux

It doesn't work! System can 't find my module and of course.... I can't start it with modprobe:

raspberrypi:/home/pi# modprobe lan743x
modprobe: FATAL: Module lan743x not found in directory /lib/modules/5.15.32-v7l+

raspberrypi:/lib/modules/5.15.32-v7l+/kernel/drivers/net/ethernet/microchip# modinfo lan743x

-rw-r--r-- 1 root root 52828 Jul 30 15:20 lan743x.ko

NOTE: That lan743x.ko is the same for both kernel versions.... Do I have to re-compile this patch ( lan743x_main.c file) for every versions?

[pelwell]

Do I have to re-compile this patch ( lan743x_main.c file) for every versions?

Yes, you do.

[user-redans]

Ok, but how can I re-compile for a new kernel version?

When I compile with make command, I' ve received this:

raspberrypi:/home/pi/lan743x# make
make: *** No targets. Stop.

This is my lan743x directory:
