Description john.vincent.xa 2025-11-17 17:35:00 UTC
1. Please describe the problem:
The Renesas RZ/G2L installation is failing due to RZ DMA engine not enabled

Please enable the following config:

CONFIG_RZ_DMAC=y

The source code location to update this:
https://gitlab.com/cki-project/kernel-ark/-/tree/os-build/redhat/configs/fedora/generic/arm/aarch64

2. What is the Version-Release number of the kernel:
kernel-6.18.0-0.rc6.50

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :
No

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:
Yes

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:
Yes

6. Are you running any modules that not shipped with directly Fedora's kernel?:
No

7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.

Reproducible: Always

Comment 2 john.vincent.xa 2025-11-19 09:44:18 UTC
Hi Justin

During Fedora server install on RZ/G2L board, the Linux boot is failing due to DMA engine core device is not added as built-in.

This config needs enabling as y instead of m

CONFIG_RZ_DMAC=y

Best Regards
John
