jgetas · 2026-01-15T08:24:46Z

Add OS image modules for building QNX8 x86_64 and arm64 images running on QEMU.

Dependency is mainly a QNX SDP 8.0.3 with virtio driver ("block" and "startup") support. See qnx8/README.md.

please use name as in other repos ie arm64-qnx8

I could do this but this is supposed to be used for x86_64 as well, because it is independent from target architecture - just using the host sdp. I did not want to create 2 configs with duplicate content.

this should be synchornized with SDP in toolchain. I habve no idea howwe do it now ?

Yes, I agree. But I think it is no strict dependency from the build result, only if consumers want to pair it with compilation results from cpp toolchain. Therefore I thought let's merge the os_image first - currently nobody is using it anyway.
Maybe let's discuss on Monday in score infra meeting.

I'd like to use it right away in ref int. even before merging this as PoC and lifecycle is waiting in stands for it.

its not going to work for others or ? this is dev dep anyway.

? What do you mean? The sdp.BUILD? I wanted to have this in the rules_imagefs, but Nikola objected. Therefore I had to add it here. The content is IMHO generic for all QNX SDPs. So I don't expect this file will change.

where is the mechanism to import files into image from other bazel targets like in https://github.com/eclipse-score/reference_integration/blob/main/images/qnx_x86_64/build/BUILD#L59 exported via this repo. So the questions is if we shall rather provide also some extension from this repo too or macro so user can add it's own stuff easily?

Would be good that before merging this we have PoC PR in ref_int replacing current setup.

qnx8/README.md

+
+### Autostart script
+
+If the file `/opt/score/autostart.sh` exists on the mounted file system, it is executed at the end of the OS image startup sequence.


So after reading through 212 lines i could extract most important parts:

extern module cannot modify ifs (does not sound good, ie for some examples you need specific mount points, or additional qnx tools)
-/opt/score/autostart.sh how this gets into the image ? The assumption is that provided qnx6fs has this ?

extern module must pack its stuff into qnx6fs

I tihnk this shall be breifly mentioned in main readme as MOST important points. Also I wonder whether this repo shall really provide abstraction via macro/extensions and gather all that from user so it's crystal clear. Now it's a bit foggy imho

The main idea is that the OS images are generic and not modified for individual use cases. If you want to use it for your whatever-tests, either create such a qnx6fs on your side and put all you want in it. Or boot with empty partition and populate it during runtime. The first qnx6fs partition on the external QEMU disk will automatically be mounted at /opt/score. If there is a "autostart.sh" on it, it will be automatically launched after boot.

Advantages are imho:

hiding complexity of creating OS images from testers

fast re-use by bazel cache

sort of standard OS foundation for target testing

I'll try to outline this better in the README.
