| Summary | 0000622: Request to backport recent GVE patches for Google Cloud overcommited Gen3+ VMs for AlmaLinux 9 | ||||
| Description | Currently, the maximum queue depth supported for gVNIC on overcommited Gen3+ VMs such as N4 is 1K, whereas the maximum queue depth supported on Gen1/Gen2 VMs is 2K. Customers who are migrating their workloads from N2 to N4 have requested higher queue depth support on N4 VMs. GVE driver changes to support greater than 1K queue depth for overcommitted Gen3+ have been upstreamed to Linux kernel recently: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=a2f19184014f https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=07993df56091 | ||||

|
A decision on this hasn't been made one way or the other by ALESCo yet, but we're working on test kernel builds with these changes. |
|
|
ALESCo approved these changes and backports. An AlmaLinux 9 test kernel has been built based on these commits, with significant backporting work. https://build.almalinux.org/build/77792 You can install it as follows: dnf upgrade --repofrompath gvnic-qd-backport,https://build.almalinux.org/pulp/content/builds/AlmaLinux-9-x86_64-77792-br/ NVR for this test kernel is 5.14.0-687.41.1.el9_8 |
|
|
The test output looked identical to that from AlmaLinux 10 in https://bugs.almalinux.org/view.php?id=621 This kernel update will be available in production repos later today. |
