[dpdk-dev] [PATCH 0/8] add asym support in crypto_octeontx PMD

[Anoob Joseph]

This series adds asymmetric crypto support in 'crypto_octeontx' PMD.

Features supported: RSA & modular exponentiation

Kanaka Durga Kotamarthy (4):
  crypto/octeontx: add device type mailbox routine
  crypto/octeontx: add RSA and modexp asym capabilities
  crypto/octeontx: add asymmetric session operations
  common/cpt: add helper functions for asymmetric crypto

Sunila Sahu (4):
  crypto/octeontx: add asymmetric op enqueue function
  crypto/octeontx: add asymmetric op dequeue function
  app/test: register octeontx PMD to asym testsuite
  doc: update octeontx asymmetric features

I believe this will give Asym capabilities always. As the feature flag
RTE_CRYPTODEV_FF_ASYMMETRIC_CRYPTO will always be set, as the flags are set in init.

It will never go in else.

[Anoob] The flags is set based on the type of underlying device. The crypto module on OCTEONTX exposes two kinds of VFs. One which does only symmetric and one which does only asymmetric. Both are never supported together for a VF, and hence the if...else.

From the first patch, crypto/octeontx: add device type mailbox routine

	switch (cptvf->vftype) {
	case OTX_CPT_VF_TYPE_AE:
		/* Set asymmetric cpt feature flags */
		c_dev->feature_flags = RTE_CRYPTODEV_FF_ASYMMETRIC_CRYPTO |
				RTE_CRYPTODEV_FF_HW_ACCELERATED;
		break;
	case OTX_CPT_VF_TYPE_SE:
		/* Set symmetric cpt feature flags */
		c_dev->feature_flags = RTE_CRYPTODEV_FF_SYMMETRIC_CRYPTO |
				RTE_CRYPTODEV_FF_HW_ACCELERATED |
				RTE_CRYPTODEV_FF_SYM_OPERATION_CHAINING |
				RTE_CRYPTODEV_FF_IN_PLACE_SGL |
				RTE_CRYPTODEV_FF_OOP_SGL_IN_LB_OUT |
				RTE_CRYPTODEV_FF_OOP_SGL_IN_SGL_OUT;
		break;

Hope this clarifies.

I am not sure how this is working.
In your octeontx device, you will have both RTE_CRYPTODEV_FF_ASYMMETRIC_CRYPTO
and RTE_CRYPTODEV_FF_SYMMETRIC_CRYPTO will be set together. So it will not go in else
in any case.
Please check in rest of the PMD also if this assumption is made somewhere else also.

[Anoob] The crypto VFs on octeontx would be either sym/asym and cannot be both. Hence the above would work. But, you are right. In the above, it should be,

sym_lens = 0;
asym_lens = 0;

If (SYM) {
    /* set various lens for sym */
}

If (ASYM) {
    /* set various lens for asym */
}

len = MAX(sym_len, asym_len);

I'll make the required changes in v2. Hope this clarifies.

[Anoob] The above code snippet is only applicable for crypto_octeontx PMD. And hence the current code should be fine. Initially, I mistook that the suggestion was for a common routine. Nevertheless, I'll add a comment stating that only one feature is supported.

Probably you should have some heading to specify Symmetric crypto Algorithms also.

[Anoob] Do you recommend adding that change also in this patch or should I submit a separate patch for redesigning that. FYI. For crypto_octeontx2, following is the list we are adding. Do you suggest a similar change there also?

* ``RTE_CRYPTO_CIPHER_ZUC_EEA3``

Hash algorithms:

* ``RTE_CRYPTO_AUTH_NULL``
* ``RTE_CRYPTO_AUTH_AES_GMAC``
* ``RTE_CRYPTO_AUTH_KASUMI_F9``

You can refer to qat.rst.
I believe it will not be a big change and is totally relevant in this patchset, so you can have
That in this patchset.
Yes you should do this in octeontx2 as well.

[dpdk-dev] [PATCH v2 0/5] add asym support in crypto_octeontx PMD

[Anoob Joseph]

This series adds asymmetric crypto support in 'crypto_octoentx' PMD.

Changes in v2:
* Squashed patches as directed by Akhil
* Split the doc patch and added documentation along with feature
* Added check for ASYM SESSIONLESS (not supported currently)
* Made separate enqueue & dequeue routines for sym & asym
* Minor updates to documentation

Kanaka Durga Kotamarthy (3):
  crypto/octeontx: add device type mailbox routine
  crypto/octeontx: add asymmetric session operations
  common/cpt: add helper functions for asymmetric crypto

Sunila Sahu (2):
  crypto/octeontx: add asymmetric enqueue/dequeue ops
  app/test: register octeontx PMD to asym testsuite

Re: [dpdk-dev] [PATCH v2 0/5] add asym support in crypto_octeontx PMD

[Anoob Joseph]

Hi Akhil

You can use the following description.

+* **Added asymmetric support to Marvell OCTEON TX crypto PMD.**
+
+  Added support for asymmetric operations in Marvell OCTEON TX cypto PMD. Supports RSA
+  and modexp operations.
+

Thanks,
Anoob
