Public bug reported: [Impact]
Some workloads, for example SQL Server, require PMEM support from different modules for performance reasons. Most of this modules are included in the linux-modules-extra package but linux-azure doesn't install it by default. Move these modules to the linux-modules package so they are installed by default: nd_blk.ko, nd_pmem.ko, device_dax.ko, dax_hmem.ko, kmem.ko, dax_pmem.ko, dax_pmem_compat.ko, virtio_pmem.ko , nd_virtio.ko. (Some modules are not available depending on the kernel version) [Test Plan] The modules listed below should be included in the linux-modules package instead of in the linux-modules-extra package. [Where problems could occur] The additional modules shouldn't cause any troubles and in case of problem they can be blacklisted or removed from linux-modules. ** Affects: linux-azure (Ubuntu) Importance: Undecided Status: New ** Affects: linux-azure-4.15 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux-azure (Ubuntu Bionic) Importance: Undecided Status: Invalid ** Affects: linux-azure-4.15 (Ubuntu Bionic) Importance: High Assignee: Marcelo Cerri (mhcerri) Status: In Progress ** Affects: linux-azure (Ubuntu Focal) Importance: High Assignee: Marcelo Cerri (mhcerri) Status: In Progress ** Affects: linux-azure-4.15 (Ubuntu Focal) Importance: Undecided Status: Invalid ** Affects: linux-azure (Ubuntu Groovy) Importance: High Assignee: Marcelo Cerri (mhcerri) Status: In Progress ** Affects: linux-azure-4.15 (Ubuntu Groovy) Importance: Undecided Status: Invalid ** Affects: linux-azure (Ubuntu Hirsute) Importance: Undecided Status: New ** Affects: linux-azure-4.15 (Ubuntu Hirsute) Importance: Undecided Status: Invalid ** Also affects: linux-azure (Ubuntu) Importance: Undecided Status: New ** No longer affects: linux (Ubuntu) ** Also affects: linux-azure-4.15 (Ubuntu) Importance: Undecided Status: New ** Also affects: linux-azure (Ubuntu Hirsute) Importance: Undecided Status: New ** Also affects: linux-azure-4.15 (Ubuntu Hirsute) Importance: Undecided Status: New ** Also affects: linux-azure (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux-azure-4.15 (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux-azure (Ubuntu Bionic) Importance: Undecided Status: New ** Also affects: linux-azure-4.15 (Ubuntu Bionic) Importance: Undecided Status: New ** Also affects: linux-azure (Ubuntu Groovy) Importance: Undecided Status: New ** Also affects: linux-azure-4.15 (Ubuntu Groovy) Importance: Undecided Status: New ** Changed in: linux-azure (Ubuntu Bionic) Status: New => Invalid ** Changed in: linux-azure-4.15 (Ubuntu Focal) Status: New => Invalid ** Changed in: linux-azure-4.15 (Ubuntu Groovy) Status: New => Invalid ** Changed in: linux-azure-4.15 (Ubuntu Hirsute) Status: New => Invalid ** Changed in: linux-azure-4.15 (Ubuntu Bionic) Importance: Undecided => High ** Changed in: linux-azure-4.15 (Ubuntu Bionic) Status: New => In Progress ** Changed in: linux-azure-4.15 (Ubuntu Bionic) Assignee: (unassigned) => Marcelo Cerri (mhcerri) ** Changed in: linux-azure (Ubuntu Focal) Importance: Undecided => High ** Changed in: linux-azure (Ubuntu Focal) Status: New => In Progress ** Changed in: linux-azure (Ubuntu Focal) Assignee: (unassigned) => Marcelo Cerri (mhcerri) ** Changed in: linux-azure (Ubuntu Groovy) Importance: Undecided => High ** Changed in: linux-azure (Ubuntu Groovy) Status: New => In Progress ** Changed in: linux-azure (Ubuntu Groovy) Assignee: (unassigned) => Marcelo Cerri (mhcerri) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1921411 Title: linux-azure: Install PMEM modules by default Status in linux-azure package in Ubuntu: New Status in linux-azure-4.15 package in Ubuntu: Invalid Status in linux-azure source package in Bionic: Invalid Status in linux-azure-4.15 source package in Bionic: In Progress Status in linux-azure source package in Focal: In Progress Status in linux-azure-4.15 source package in Focal: Invalid Status in linux-azure source package in Groovy: In Progress Status in linux-azure-4.15 source package in Groovy: Invalid Status in linux-azure source package in Hirsute: New Status in linux-azure-4.15 source package in Hirsute: Invalid Bug description: [Impact] Some workloads, for example SQL Server, require PMEM support from different modules for performance reasons.
