hey @xijunli ! Could you please test that the driver now works as expected? I have placed the files here https://kernel.ubuntu.com/~lukenow/lp2012335/ , but you should only need to install the modules. Let me know if that works for you
Thanks, - Luke -- 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/2012335 Title: Ubuntu 22.04 raise abnormal NIC MSI-X requests with larger CPU cores (256) Status in linux package in Ubuntu: Fix Released Status in linux source package in Jammy: In Progress Bug description: System Configuration OS: Ubuntu 22.04 LTS Kernel: 5.15.0-25-generic CPUs: 256 NIC: Intel E810 NIC with 512 MSIx vectors each function Errors Not enough device MSI-X vectors, requested = 260, available = 253 Findings (1) the current ice kernel driver (ice_main.c) will pre-allocate all required number of msix (even it's not enough for big core CPUs) (2) the commit https://github.com/torvalds/linux/commit/ce4626131112e1d0066a890371e14d8091323f99 has improved this logic, and it seems merged into kernel version from v6.1 So for supporting the new CPUs with more than 252 vCPUs, will Ubuntu kernel backport above patch to the current kernel (v5.15) ?
