[PATCH v10 1/1] crypto: Introduce RSA algorithm

There are two parts in this patch: 1, support akcipher service by cryptodev-builtin driver 2, virtio-crypto driver supports akcipher service In principle, we should separate this into two patches, to avoid compiling error, merge them into one. Then virtio-crypto gets request from guest side, and

[PATCH v10 0/1] Introduce akcipher service for virtio-crypto

v9 - v10: - Minor fix of coding style by v9. v8 - v9: - Fix compiling error reported by clang-13/14: opt->hash_alg = cryptodev_builtin_get_rsa_hash_algo(); this leads implicit convertion from 'int' to 'uint32'. 'if (opt->hash_alg < 0)' is always false. Thanks to Philippe Mathieu-Daudé. v7 -

[PATCH v1] drivers/virtio: Clarify CONFIG_VIRTIO_MEM for unsupported architectures

Let's make it clearer that simply unlocking CONFIG_VIRTIO_MEM on an architecture is most probably not sufficient to have it working as expected. Cc: "Michael S. Tsirkin" Cc: Jason Wang Cc: Gavin Shan Signed-off-by: David Hildenbrand --- drivers/virtio/Kconfig | 8 +--- 1 file changed, 5 i
