We need DTBs for most ARM systems, so this is a mandatory requirement.

We must update dtc, then. Could you take care of it, please? Because it must go through SLE, I think. Thanks, Guillaume

Not necessarily. While it's preferrable to share packages between SLE and Leap, we can use a newer package in Leap if there is a good reason (to be honest, I would rather say we do so more often than we should). So I would suggest to start by asking SLE dtc maintainer (Cc-ed) if he would be willing to either upgrade dtc for SLE15 SP2 to version compatible with DTBs from 5.3 kernel tree or backport necessary changes. If not, it would IMHO qualify as good reason for submitting a version upgrade to Leap 15.2.

For the sake of completeness, I believe the dtc compatibility issue (i.e. build failures) should be resolved before we (re)enable the DTB build in openSUSE-15.2 branch.

Why unmaintained? They are maintained as the rest of sources of the Linux kernel. Non-UEFI ARM systems require those DTB to boot a Linux kernel. The DTB is passed by the bootloader (u-boot/grub). Cheers, Guillaume

I don't dispute that DTBs are needed. But do they come from the kernel package?

Yes, they are. From arch/arm/boot/dts/ and arch/arm64/boot/dts/

Yes, there are DTBs in the kernel. What exactly uses these unmaintained DTBs?

Why unmaintained? They are maintained as the rest of sources of the Linux kernel. Because nobody backports fixes for them. Non-UEFI ARM systems require those DTB to boot a Linux kernel. The DTB is passed by the bootloader (u-boot/grub).

A DTB is passed by u-boot/grub. Does it come from the kernel package, though?

Yes, it does.

How exactly? Thanks Michal

Why unmaintained? They are maintained as the rest of sources of the Linux kernel. Because nobody backports fixes for them. Non-UEFI ARM systems require those DTB to boot a Linux kernel. The DTB is passed by the bootloader (u-boot/grub).

I know DTBs.

What I don't know is where the DTB that gets loaded if you boot (open)SUSE comes from, specifically.

They are installed on the image used to boot the system: https://build.opensuse.org/package/show/openSUSE:Leap:15.2:ARM:Images/JeOS Cheers, Guillaume

Why unmaintained? They are maintained as the rest of sources of the Linux kernel. Because nobody backports fixes for them. Non-UEFI ARM systems require those DTB to boot a Linux kernel. The DTB is passed by the bootloader (u-boot/grub).

A DTB is passed by u-boot/grub. Does it come from the kernel package, though?

Yes, it does.

How exactly?

U-Boot loads the right DTB for the current platform, from filesystem to RAM and passes the pointer to the kernel. You may find this interesting, if you do not know DTB: https://events.static.linuxfound.org/sites/events/files/slides/petazzoni-dev...

I know DTBs.

What I don't know is where the DTB that gets loaded if you boot (open)SUSE comes from, specifically.

For example, checking a system I am running I see this: file /boot/vc/bcm2710-rpi-3-b-plus.dtb is not owned by any package How did the file get there? Thanks Michal

They are installed on the image used to boot the system: https://build.opensuse.org/package/show/openSUSE:Leap:15.2:ARM:Images/Je OS

Could we move forward here to re-enable the DTBs on Leap 15.2, please? Thanks, Guillaume N��r��y隊Z)z{.��w��칻�&ޢ��'��-��w�zf��^�ˬzG��~� ޮ�^�ˬz��

RPi3 is different. The dtb of RPi comes from raspberrypi-firmware-dt.rpm Regards, Matthias -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

Hi, Could we finally enable DTBs for 15.2, please? Thanks, Guillaume
