** Description changed: + [SRU Justification] + + [Impact] + + DELL Pro 14 Premium PA14260 has many SKUs and two of them have this + upside-down issue. The `dmi_first_match()` call will either return NULL + or the first matching entry, so the original implementation is not + effective for the second case that is with a BBG809N3A_B sensor. + + [Fix] + + Ubuntu sauced fix that extends the original platform matching process to + be more flexible to cover this special case. + + [Test Plan] + + 1. Install kernel from the -proposed pocket and reboot into it. + 2. Use http://webcamtests.com/ to test camera streaming. The affected SKU should now gives the correct orientation. + + [Where problems could occur] + + The new implementation has exactly the same behaviour for other existing + entries, but correct the affected ones. No known issue yet. + + [Other Info] + + Proposed to the upstream ipu6-drivers github repository in + https://github.com/intel/ipu6-drivers/pull/445. Intel is working on + upstreaming these platform fixes. + + Nominate for oem-6.17, oem-7.0, resolute, stonking. + + ========== original bug report ========== + This is a follow-up for bug 2146517, because Bolan has a SKU with a different BBG809N3A_B sensor that Canonical doesn’t have, and the driver patch from ipu6-drivers doesn’t go well with this second case. Proposed fix to the upstream in https://github.com/intel/ipu6-drivers/pull/445. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2155837 Title: MIPI camera of a BBG809N3A_B sensor SKU of the DELL Pro 14 Premium PA14260 renders upside-down To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2155837/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
