All autopkgtests for the newly accepted linux-meta-hwe-5.15 (5.15.0.53.59~20.04.21) for focal have finished running. The following regressions have been reported in tests triggered by the package:

FW API -64 supported by oem-5.14, and -67 in v5.16. Not reproducible on every platform with AX211 installed, and the chances of such failures vary from one to another. [Fix] A few solutions were considered. The very first one is to ask Intel to fix -64 firmware directly, and the answer is a solid no claimed -64 is not the planned production version of AX211. It's also possible to backport FW API from v5.16, but while iwlwifi FW API is more or less a black box to us and the new FW APIs also depends on updates on the wireless stack, this is going to be very risky and actually we had regressions before after such backports. The last viable solution is to run backport-iwlwifi-dkms >= rev 8580 on the effected platforms. This means oem-5.14 and its migration target, hwe-5.15 will not be able to drive this piece of hw flawlessly without backport-iwlwifi-dkms installed. However, while we need secureboot to be enabled on these platforms, backport-iwlwifi-dkms must also be signed somehow. There are two possible method to achieve this, too. One, to prebuild this dkms as zfs and v4l2loopback does. However, while backport-iwlwifi-dkms generates kernel modules with exactly the same name as the in-tree ones, when prebuilt, they'll be available directly from the linux-modules package and therefore overrides the in-tree ones always, turning the in-tree driver completely useless and risk the stability of all other generic installations. The second one is to build backport-iwlwifi-dkms as nvidia graphic drivers in the linux-restricted-modules source package. In this way, affected platforms may install the corresponding packages when needed without interfering others. However, l-r-m is for restricted modules that needs special care of redistribution of its binaries, and backport-iwlwifi-dkms is GPL licensed. Here a similar but simpler process in the main kernel tree is re-implemented. Two additional packages, linux-modules-MODULE-PKGVER-ABINUM-FLAVOUR and its meta package linux-modules-MODULE-FLAVOUR will be created. [Test Case] Test builds: ./jammy/amd64/linux-modules-iwlwifi-5.15.0-27-generic_5.15.0-27.28_amd64.deb ./jammy/amd64/linux-modules-iwlwifi-generic_5.15.0-27.28_amd64.deb ./unstable/amd64/linux-modules-iwlwifi-5.17.0-8-generic_5.17.0-8.8_amd64.deb ./unstable/amd64/linux-modules-iwlwifi-generic_5.17.0-8.8_amd64.deb ./oem-5.17/amd64/linux-modules-iwlwifi-5.17.0-1003-oem_5.17.0-1003.3_amd64.deb ./oem-5.17/amd64/linux-modules-iwlwifi-oem_5.17.0-1003.3_amd64.deb ./oem-5.14/amd64/linux-modules-iwlwifi-5.14.0-1033-oem_5.14.0-1033.36_amd64.deb ./oem-5.14/amd64/linux-modules-iwlwifi-oem_5.14.0-1033.36_amd64.deb [Where problems could occur] The latest (9858-0ubuntu2) backport-iwlwifi-dkms/jammy actually fails to build under this proposed process. Debdiff attached to the same bug. Different from nvidia packages built from l-r-m, the generated package names do not carry an additional short version string, e.g. nvidia-410, as there is no such necessity to build multiple versions of iwlwifi. The modules are installed to /lib/modules/<kver>/kernel/iwlwifi, not iwlwifi-9858/. ========== linux-meta-hwe-5.15 SRU ========== [Impact] To bring standalone dkms module builds to hwe-5.15 as well. [Fix] Same fix that has been applied to Unstable/Kinetic/Jammy/OEM-6.0/OEM-5.14/HWE-5.19. [Test Case] This should generate meta packages: * linux-modules-iwlwifi-generic-hwe-20.04 * linux-modules-iwlwifi-generic-hwe-20.04-edge * linux-modules-iwlwifi-oem-20.04 * linux-modules-iwlwifi-oem-20.04d [Where problems could occur] This creates only the meta packages that are currently missing. No function changes. [Other Info] While this has been ported to all other series in concern, only hwe-5.15 is nominated for fix here. The patch titled "UBUNTU: [Packaging] skip standalone dkms modules for virtual flavour" was not tagged with a BugLink line, but we'd need that to skip generating linux-modules-foo meta packages for virtual flavour. ========== backport-iwlwifi-dkms SRU ========== In order to be compiled with dkms-build in kernel source package, the kernel header dir will not be /lib/modules/<version>/build but a temporary directory. This change specifies KLIB_BUILD from dkms variable ${kernel_source_dir}. [backport-iwlwifi-dkms] Under some circumstances, dkms is invoked as: `/usr/sbin/dkms build --kernelsourcedir ...` and yet the dkms make command in this package has: MAKE="'make' -j$(num_cpu_cores) KLIB=/lib/modules/$kernelver" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/backport-iwlwifi-dkms/+bug/1969434/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
