kernel BUG at drivers/crypto/caam/jr.c

[kunsong]

hi,

Check log, call trace output "irqstate: 00000103"

Check code: drivers/crypto/caam/jr.c

286 if (irqstate & JRINT_JR_ERROR) {
287 dev_err(dev, "job ring error: irqstate: %08x\n", irqstate);
288 BUG();
289 }

caam_jr_remove function

238 if (atomic_read(&jrpriv->tfm_count)) {
239 dev_err(jrdev, "Device is busy\n");
240 return -EBUSY;
241 }

Judging from the current log, the caam_jr_remove function was called, but the check device is still busy.

I found a similar problem:
https://community.nxp.com/t5/Layerscape/Kernel-panic-with-Layerscape-17-09-kernel-4-9-35/m-p/697467

NXP suggest:
"You are working with the kernel from LSDK 1709 ( 4.9.35), but your u-Boot seem to be taken from an earlier release (1709 u-Boot is 2017.07, your one is 2017.03).
Can you update your u-Boot and try again?"

Check our version:

nxp-ls1028 kernel: Linux version 5.10.154*
nxp-ls1028 kernel: efi: EFI v2.80 by Das U-Boot

U-Boot 2019.10+fsl+g3d542a3d22 (Dec 21 2021 - 20:21:21 +0000)

our uboot version is Higher, do you know the possible cause of this problem?

Thanks！

I suspect there is problem with your Linux Kernel source code.

Please refer to Linux SDK release from the following link 

https://github.com/nxp-qoriq/yocto-sdk

Yocto branch and version
========================
| Branch      | Version          |
|-------------|------------------|
| mickledore  | YP 4.2–lf-6.1.36 |
| langdale    | YP 4.1–lf-6.1.1  |
| kirkstone   | YP 4.0–lf-5.15.71|
| honister    | YP 3.4–lf-5.15.5 |
| hardknott   | YP 3.3–lf-5.10.72|

We didn't release Linux Kernel 5.10.154* to customer.

Please download one formal release LSDK to do verification on your target board.

yes, We have a customized kernel system, and this problem is difficult to reproduce.

Do you know what "irqstate: 00000103 " means ?

I didn't find any definition in the manual

[kunsong]

hi, @bpe 

Can you give some advice?

Do you know what this value means?  irqstate: 00000103 

Thanks!
