** Description changed: + [SRU Justification] + + [Impact] + + backport-iwlwifi-dkms has a few problems to prevent it from loading + either kernel modules itself or the runtime firmware correctly. + + The first issue is "unknown symbol iwl_mei_is_connected" error at module + probing. This affects revsions >= 9241 where iwlmei module was first + introduced in commit 71e53a8aae59 ("mirror: multi-input commit"). This + can be addressed by cherry picking commit cc7d59edeeae + ("[BUGFIX][NOUPSTREAM] iwlwifi: bump min kernel version for iwlmei") of + rev 9255 that bumps iwlmei prerequisite kernel version to 5.14, and + commit 87dce6e9817a ("[BUGFIX][NOUPSTREAM] iwlwifi: iwlmei isn't going + to be merged anytime soon") of rev 9543 that bumps to 5.20. Therefore + this affects Impish & Jammy that currently have 9340. + + The second problem is that even we addressed 9340 with aforementioned + fix backported, the iwlwifi module may still fail to load firmware that + is known fixed in at least 9580 that is being proposed. This would + affects Focal oem-5.14 as well. + + [Fix] + + Bump to 9580 that fixes both issues stated above. + + [Test Case] + + Compile and run against Focal oem-5.14/hwe-5.13/hwe-5.15 kernels, as + well as Impish 5.13 and Jammy 5.15. + + [Where problems could occur] + + While the revision number represents the commits since the git root + commit of backport-iwlwifi, this is going to back port more than a + thousand commits for Focal (8324 -> 9580) and 240 ones for Impish/Jammy + (9340 -> 9580), there can always be issue like we have here now or later + for kernels of a more recent version. While this package is to enable + people running legacy kernels to be able to enjoy their new toys, new + hardware support and bug fixes shall be backported as long as needed to + justify its name "backport-iwlwifi-dkms" here. + + ========== original bug report ========== + Since backport-iwlwifi version 9241[1], a new module iwlmei was introduced but not yet included in the dkms.conf installed. This fails the kernel module loading with: - iwlwifi: Unknown symbol iwl_mei_is_connected (err -2) + iwlwifi: Unknown symbol iwl_mei_is_connected (err -2) [1]: https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport- iwlwifi.git/commit/?id=71e53a8aae592d02972522561eac899311ea9319
