Hi gonglei,
Sorry to bother you again.
I notice that numa node is supported with virtio-crypto device. Is there
multiple PCIE root bridges with different numa nodes supported on some
VM models?
I ask this question because I do not know whether it is possible to
preallocate virtio_crypto_op_data_req buffer and IV buffer within
structure virtio_crypto_sym_request. Only that there is no node
information when virtio_crypto_sym_request is allocated.

Subject: virtio-crypto: Inquiry about virtio crypto
Hi gonglei,
I am investigating how to use HW crypto accelerator in VM. It seems that
virtio-crypto is one option, however only aes skcipher algo is supported and
Actually akcipher service had been supported by virtio-crypto in 2022.
virtio-crypto device is not suggested by RHEL 10.

I want to know what is the potential issued with virtio-crypto.
This question is too big, maybe you'd better ask RHEL guys. :(
