Looking at the code we didn't see any reasons why those drivers might not work on other architectures. We've successfully built all of them on x86, arm64, arm32, mips64, powerpc64, riscv64 and sparc64. We also have tested the driver with an Intel Corporation C62x Chipset QuickAssist Technology (rev 04) PCIe card on an arm64 server. After the numa patch, it works with the AF_ALG crypto userland interface, allowing us to encrypt some data with cbc for instance. We've also successfully created some VF, bound them to DPDK, and used the card this way, thus showing some real life usecases of x86 do work on arm64 too.
