Hi,

Bisect pointed commit:
commit 002905eca5bedab08bafd9e325bbbb41670c7712
Author: Peng Ma <peng.ma@nxp.com>
Date:   Thu Jun 13 10:27:08 2019 +0000
    dmaengine: fsl-edma: support little endian for edma driver

as a reason of NFSv4 root boot failures. Toradex Colibri VF50 (Cortex
A5) on Toradex Iris board.

The user-space starts but hangs - a lot of messages are missing or
seriously delayed.

Please revert the patch of fix it. If needed I can provide more
details about test system - let me know.

Full log attached.

Best regards,
Krzysztof

Hi,

Bisect pointed commit:
commit 002905eca5bedab08bafd9e325bbbb41670c7712
Author: Peng Ma <peng.ma@nxp.com>
Date:   Thu Jun 13 10:27:08 2019 +0000
    dmaengine: fsl-edma: support little endian for edma driver

as a reason of NFSv4 root boot failures. Toradex Colibri VF50 (Cortex
A5) on Toradex Iris board.

The user-space starts but hangs - a lot of messages are missing or
seriously delayed.

Please revert the patch of fix it. If needed I can provide more
details about test system - let me know.

Full log attached.

Does this fix the problem?

I am not saying this is the proper fix as we should not break old dtb's.

Hi,

No, unfortunately it does not help.

Just looked at "dmaengine: fsl-edma: support little endian for edma
driver" more closely and this one assumes that there wasn't
little-endian support originally, which is incorrect.

Vybryd, i.MX7ULP uses edma in little-endian mode, so I think that we
should revert it.

Thanks

Hi Krzysztof,

I am sorry, It is my mistake to forget about VF50 used EDMA IP with little endian.
The Register(CHCFG0 - CHCFG15) of our platform designed as follows:
*-------------------------------------------------------------------------------*
|     Offset   | Big endian Register| Little endian Register|
|---------------------|--------------------------|-----------------------------|
|     0x0     |     CHCFG0    |     CHCFG3      |
|---------------------|--------------------------|-----------------------------|
|     0x1     |     CHCFG1    |     CHCFG2      |
|---------------------|--------------------------|-----------------------------|
|     0x2     |     CHCFG2    |     CHCFG1      |
|---------------------|--------------------------|-----------------------------|
|     0x3     |     CHCFG3    |     CHCFG0      |
|---------------------|--------------------------|-----------------------------|
|     ...      |        ......     |         ......      |
|---------------------|--------------------------|-----------------------------|
|     0xC     |     CHCFG12   |     CHCFG15     |
|---------------------|--------------------------|-----------------------------|
|     0xD     |     CHCFG13   |     CHCFG14     |
|---------------------|--------------------------|-----------------------------|
|     0xE     |     CHCFG14   |     CHCFG13     |
|---------------------|--------------------------|-----------------------------|
|     0xF     |     CHCFG15   |     CHCFG12     |
*-------------------------------------------------------------------------------*

So we need this patch, I make some changes,Please help me to test attatchment on VF50 board,
Thanks.

Best Regards,
Peng

You need to change the Subject to something like:

Subject: [PATCH] dmaengine: fsl-edma: Add support for LS1028A

Also, in the commit log, please change "Our platforms" to "LS1028A"

Please remove this part: "Current eDMA driver does not support Little endian"

,which is not correct.

With the patch VF50 boots fine.

BTW, Colibri VF50 nicely boots from network almost out of the box so
it is easy to add it to automated tests for simple boot tests. This
way you do not have to manually test it on such platform...

Best regards,
Krzysztof

Hi Fabio,

Thanks very much for your suggestion, I will do some changes then to
Send upstream review.
