I verified lttng-modules 2.12.5-1ubuntu2~20.04.1 build, install and basic functionality in a Focal VM running both generic 5.4 and hwe-5.11 kernels.
autopkgtests with both kernels also completed successfully: * hwe-5.11 - amd64: https://autopkgtest.ubuntu.com/results/autopkgtest-focal/focal/amd64/l/lttng-modules/20210727_163927_ce8c0@/log.gz - arm64: https://autopkgtest.ubuntu.com/results/autopkgtest-focal/focal/arm64/l/lttng-modules/20210727_163709_bdf0f@/log.gz - ppc64el: https://autopkgtest.ubuntu.com/results/autopkgtest-focal/focal/ppc64el/l/lttng-modules/20210727_163437_883e8@/log.gz - s390x: https://autopkgtest.ubuntu.com/results/autopkgtest-focal/focal/s390x/l/lttng-modules/20210727_163019_9d43f@/log.gz * generic (5.4) - amd64: https://autopkgtest.ubuntu.com/results/autopkgtest-focal/focal/amd64/l/lttng-modules/20210727_122206_6ae80@/log.gz - arm64: https://autopkgtest.ubuntu.com/results/autopkgtest-focal/focal/arm64/l/lttng-modules/20210727_121907_6ae80@/log.gz - ppc64el: https://autopkgtest.ubuntu.com/results/autopkgtest-focal/focal/ppc64el/l/lttng-modules/20210727_121636_6ae80@/log.gz - s390x: https://autopkgtest.ubuntu.com/results/autopkgtest-focal/focal/s390x/l/lttng-modules/20210727_121307_6ae80@/log.gz ** Tags removed: verification-needed-focal ** Tags added: verification-done-focal ** Changed in: linux-hwe-5.11 (Ubuntu) Status: New => Invalid ** Changed in: linux-hwe-5.11 (Ubuntu Focal) Status: New => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-5.11 in Ubuntu. https://bugs.launchpad.net/bugs/1932165 Title: lttng-modules/2.12.2-1ubuntu1~20.04.2 ADT test failure with linux- hwe-5.11/5.11.0-20.21~20.04.1 Status in linux-hwe-5.11 package in Ubuntu: Invalid Status in lttng-modules package in Ubuntu: New Status in linux-hwe-5.11 source package in Focal: Invalid Status in lttng-modules source package in Focal: Fix Committed Bug description: [Impact] lttng-modules-dkms is reporting many build errors with linux-hwe-5.11, because of many kernel ABI changes. [Fix] Backporting the individual patches to fix all the build errors would be a lot of work and the risk to introduce regressions would be pretty high, therefore it seems safer to update to the version that is also used in impish, that works with 5.11 and it's backward compatible (so it works also with 5.4). [Test] ubuntu_lttng_smoke_test from (git://kernel.ubuntu.com/ubuntu/autotest- client-tests) [Where problems could occur] This is a major version update, so it does not contain trivial changes as backporting individual patches/fixes, so there's a risk to see regressions with lttng (however potential regressions are *only* limited to lttng). However, this way is definitely safer than backporting all the individual changes to fix the all the kernel ABI changes introduced in 5.11. [Original bug report] This is a scripted bug report about ADT failures while running lttng- modules tests for linux-hwe-5.11/5.11.0-20.21~20.04.1 on focal. Whether this is caused by the dep8 tests of the tested source or the kernel has yet to be determined.
