Backporting 8231a0e632405 (s390: Add z17 elf platform) as requested I noticed that Jammy was missing support for z16 too. To fix I backported also 6203ac3029784 (s390: add z16 elf platform). -- 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/2114450 Title: [UBUNTU 22.04] kernel: Fix z17 elf platform recognition Status in Ubuntu on IBM z Systems: Triaged Status in linux package in Ubuntu: Invalid Status in linux source package in Jammy: In Progress Status in linux source package in Noble: In Progress Status in linux source package in Oracular: Won't Fix Status in linux source package in Plucky: In Progress Status in linux source package in Questing: Invalid Bug description: [ Impact ] Glibc arch level is not recognized correctly on IBM z17 instances. Add detection for machine types 0x9175 and 0x9176 and set ELF platform name to z17. [ Fix ] Backport the following commit from upstream: - 8231a0e63240 s390: Add z17 elf platform [ Test Plan ] Boot on a z17 instance and execute: $ LD_SHOW_AUXV=1 id | grep AT_PLATFORM This must return z17.
