Test-Label: intel-Testing Test-Status: SUCCESS _Testing PASS_ DPDK git repo: dpdk commit 117e86c4b96ed761e9a7ab766261208fe81bf5ca Author: Andre Muezerie Date: Thu Mar 6 17:40:12 2025 -0800 rcu: remove VLAs There are two lines that were using VLAs, which are not supported by MSVC. 1) ../lib/rcu/rte_rcu_qsbr.c:326:12: warning: variable length array used [-Wvla] 326 | char data[dq->esize]; | ^~~~~~~~~ 2) ../lib/rcu/rte_rcu_qsbr.c:389:12: warning: variable length array used [-Wvla] 389 | char data[dq->esize]; | ^~~~~~~~~ The short-term fix is to use alloca, to allow progress with the msvc compatibility work. The long-term plan involves API changes and therefore can only be applied with a new release. This long-term plan consists of introducing some reasonable limitation on RCU DQ element size. With this change, the rcu library can be built with MSVC.
