Author Topic: Problem with bnx2 module (Read 23269 times)

mchiavac · « **on:** October 15, 2009, 10:02:36 AM »

Hello,
i start using plop from 4.0 but with all of my servers with bnx2 module, it goes in kernel panic (dell 1950, dell 2950, dell r610, ibm x3550, ibm x3650).
With all other machine with other network cards there seems no problems (tg3 or e1000 module).
It's possibile to update bnx2 module or give me some hints to integrate it in initrd?
From broadcom site the latest drivers are version 1.9.20b_1.50.13 that works great in production with centos 5.3.
Thank you.

P.S. there some way to have plop source to manipulate and recreate customized squashfs file?

yes its possible to update. the bnx2 is compiled into the kernel. you can get the kernel config from /proc/config.gz and create a new kernel.
to add the module, you dont have to edit initrd. you have to unsquashfs lib.sqfs, add it there and then create a new lib.sqfs with mksquashfs.

do you need any help, or should i create a test version with the rc of the kernel 2.26.32?

Hi,

I try to boot my server with Plop Linux 4.2.2, but network doesn't work and server prints out error messages:
bnx2: Can't load firmware file "bnx2/bnx2-mips-06-6.2.3.fw

Please, help me. How can I fix this problem? I'm a linux rookie.

Thanks,
Viktor

hello,

either you create a new lib.sqfs with bnx2/bnx2-mips-06-6.2.3.fw

or you wait. i spend this month for a new plop linux version build from scratch with the latest version of the programs.

regards
elmar

i successfully built a whole new lib.sqfs with bnx2 module, but the result is same.
where is the destination directory in lib.sqfs? I tried /firmware/bnx2 or /bnx2, but doesn't work.

Elmar · « **Reply #5 on:** August 14, 2013, 11:51:51 AM »

i forgot to say that you also have to recompile the kernel that the driver is a module.

I "hijack" this thread because i have a similar problem.
Loading of bnx2 is not possible because the firmware is missing. I think this is a bug of Plop 4.3.4.
Firmware is located in:

Code: [Select]

/lib/firmware/bnx2/bnx2/But should be in:

Code: [Select]

/lib/firmware/bnx2/After fixing this in lib.sqfs it works!

But my problem is more complex:
I boot from PXE. And then it is not possible to fetch lib.sqfs because the LAN-Card is not coming up.
So 2 things:
1. Maybe you like to fix this bnx2 bug (so all plop-users have the fix)
2. How can i (or we) fix pxe booting?

Elmar · « **Reply #7 on:** May 17, 2018, 20:54:59 PM »

Thanks for the report. It will be fixed in the next Plop Linux release.

PXE:
You have to create a custom initramfs.gz with the firmware in /lib.

Replace your new one with the "syslinux/kernel/initramfs.gz" file.

You can create the initramfs.gz with the files/scripts of the "release tools" of Plop Linux. Tell me if you need help.

Best regards
Elmar

Thx for fast response!

This was the first thing i tested, but it has NOT worked.
I think the problem is that in kernel config the bnx2 is loaded as module and not direct in the kernel (bnx2=m but should be bnx2=y).
Can this be?
BTW: During PXE-Boot i don't see a message telling me that firmware is missing.

Elmar · « **Reply #9 on:** May 19, 2018, 14:49:16 PM »

You are right, bnx2 has to be compiled into the kernel which is not done at the moment. Noted, for the next release.

Summarize requirements:
bnx2 builtin the kernel
firmware in initramfs.gz

Do you need a prepared kernel/initramfs.gz?

Best regards
Elmar

The_Raven · « **Reply #10 on:** May 22, 2018, 10:28:14 AM »

If it's possible, then yes please a kernel and initramfs.

Then i can test it.

Elmar · « **Reply #11 on:** May 23, 2018, 15:21:52 PM »

Here is a test version
https://download.plop.at/tmp/ploplinux-4.3.4-x86_64-bnx2.tar.gz

The_Raven · « **Reply #12 on:** May 24, 2018, 10:20:28 AM »

Tested an it works!

Thank you very much for the helping hand.
When do you plan to release the new plop version?

Elmar · « **Reply #13 on:** May 24, 2018, 10:24:31 AM »

Great

Release will be in the next days.

But you will still need a custom initramfs.gz, because the firmware folder is not in this file of the official release.

The_Raven · « **Reply #14 on:** May 24, 2018, 10:57:52 AM »

Why not?

Elmar · « **Reply #15 on:** May 24, 2018, 10:59:08 AM »

I want to keep the initramfs.gz as small as possible.

The_Raven · « **Reply #16 on:** June 04, 2018, 10:19:53 AM »

Tested 4.3.5 and it works (with my spezial lib.sqfs including the firmware).
Thank you for the great support!

You mean special initramfs.gz, or? The lib.sqfs should work out of the box.

The_Raven · « **Reply #18 on:** June 04, 2018, 10:47:18 AM »

Palmface...
Yes of course, special initramfs.gz, not lib.sqfs.
I need also a special usr.sqfs because of missing language, this confused me

The_Raven · « **Reply #19 on:** November 20, 2019, 14:41:53 PM »

I tried to add firmware to plop 19.4 (initramfs.gz).
But after boot i have no folder /lib/firmware and firmware loading fails.
Has something changed in plop 19.4?

Elmar · « **Reply #20 on:** November 20, 2019, 14:53:14 PM »

Now, you have to use lib.sqfs for firmware updates.

The_Raven · « **Reply #21 on:** November 20, 2019, 15:05:37 PM »

Thx for fast response!
But does this work with PXE booting?
Correct me if i am wrong, but first it loads kernel and initramfs. Then it connects the network and load the other files (usr.sqfs, lib.sqfs etc.).
But if the firmware is not present, it can't load the other files.

Elmar · « **Reply #22 on:** November 20, 2019, 15:14:55 PM »

When your network card needs a firmware file, then you can still add that file to initramfs.gz. You have to create the firmware directory. If not, then you are using the wrong initramfs tree. Are you creating initramfs.gz with the files from ploplinux-release-19.4.tar.gz?

The_Raven · « **Reply #23 on:** November 20, 2019, 15:40:24 PM »

I took the file (initramfs.gz) from plop 19.4, extract it, add /lib/firmware and repack it. After that, my "self made" initramfs.gz has about 23MB.
When i boot with this file, the folder /lib/firmware/ is not there. I think the folder /lib is overwritten by lib.sqfs.
Are i am wrong?

Edit: I have done this with older plop versions and it has worked.

Elmar · « **Reply #24 on:** November 20, 2019, 15:52:28 PM »

Correct, the /lib/firmware is not available after lib.sqfs has been mounted. /lib/firmware is then the firmware directory from lib.sqfs. When there is no /lib/firmware directory, then you are using the wrong lib.sqfs.

The_Raven · « **Reply #25 on:** November 20, 2019, 15:58:35 PM »

Then i have to add the firmware in initramfs.gz and lib.sqfs?
This way it can boot from PXE and has network access when the server is running, right?

Elmar · « **Reply #26 on:** November 20, 2019, 16:05:10 PM »

When your network card does not work without the firmware file, then you have to add it to initramfs.gz when you boot from PXE. Adding to lib.sqfs is not needed, because the firmware file has been already loaded when lib.sqfs became available.

The_Raven · « **Reply #27 on:** November 20, 2019, 16:40:27 PM »

Ok, if i boot from PXE i have to add it to initramfs.gz otherwise (boot from USB) i have to add it in lib.sqfs?
Because it seems not to work in initramfs.gz if i boot from USB.
I add it to lib.sqfs and test it.

Elmar · « **Reply #28 on:** November 20, 2019, 16:46:44 PM »

When it does not work when you boot from USB, then it boots faster from USB than PXE. In this case, put the firmware into initramfs.gz and lib.sqfs.

The_Raven · « **Reply #29 on:** November 20, 2019, 17:08:20 PM »

Ok, i think i found the problem...

Edit: Have to test it more. I tell you when i have tested it. Many thanks for your support!

The_Raven · « **Reply #30 on:** November 22, 2019, 08:34:14 AM »

ATM i am short in time, but i think it's this way:
For USB: Add the firmware files to lib.sqfs
For PXE: Add the firmware files to initramfs.gz

Elmar · « **Reply #31 on:** November 22, 2019, 09:21:03 AM »

Yes, into both.
