Subject: [RFC PATCH 0/2] Crypto: Remove x86 dependency on QAT drivers

From: Yoan Picchi <yoan.picchi@....com>

The QAT acceleration card can be very helpfull for some tasks like dealing
with IPSEC but it is currently restricted to be used only on x86 machine.
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.

Please let us know if we missed something that would warrants some further
testing.
