@Kevin, @Stephen, @Bruce, I cannot reliably answer Cody's question, and it may need further discussion.
What is your opinion on minimum Linux kernel version requirements? @Thomas: In the future, the DPDK release notes should mention the minimum Linux kernel requirements. > From: Cody Cheng [mailto:cch...@iol.unh.edu] > Sent: Thursday, 20 March 2025 21.28 > > Hi Morten, > > I am in the process of setting up a test environment at the UNH DPDK > Community Test Lab that follows the minimum supported kernel version > for DPDK.

The kernel 4.19 support stems from still supporting RHEL/CentOS 7. I wonder if this exception mentioned in the documentation [1] is still valid, or if we should bump it to RHEL/CentOS 8, which ships with kernel 4.18 [1]. RHEL/CentOS 7 support was discussed at by tech board long ago [2], but I cannot find a conclusion about the kernel version; the discussion was mostly about compiler support.
