QAT function of 'Intel C627 chipset' only supports' CPA_DC_CHAIN_HASH_THEN_COMPRESS'?

Hello,

I am currently using Intel C627 chipset.

 

While testing with the CPA_BITMAP_BIT_TEST(bitmask, bit) function, it was confirmed that the values other than'CPA_DC_CHAIN_HASH_THEN_COMPRESS (5 )'are not supported by the Intel C627 chipset.

 

As a result of testing, the values not supported by Intel C627 chipset are as follows.
CPA_DC_CHAIN_COMPRESS_THEN_HASH ( 0 ),
CPA_DC_CHAIN_COMPRESS_THEN_ENCRYPT ( 1 ),
CPA_DC_CHAIN_COMPRESS_THEN_HASH_ENCRYPT ( 2 ),
CPA_DC_CHAIN_COMPRESS_THEN_ENCRYPT_HASH ( 3 ),
CPA_DC_CHAIN_COMPRESS_THEN_AEAD ( 4 ),
CPA_DC_CHAIN_HASH_VERIFY_THEN_DECOMPRESS ( 6 ),
CPA_DC_CHAIN_DECRYPT_THEN_DECOMPRESS ( 7 ),
CPA_DC_CHAIN_HASH_VERIFY_DECRYPT_THEN_DECOMPRESS ( 8 ),
CPA_DC_CHAIN_DECRYPT_HASH_VERIFY_THEN_DECOMPRESS ( 9 ),
CPA_DC_CHAIN_AEAD_THEN_DECOMPRESS ( 10 ),
CPA_DC_CHAIN_DECOMPRESS_THEN_HASH_VERIFY ( 11 ),
CPA_DC_CHAIN_COMPRESS_THEN_AEAD_THEN_HASH ( 12 )

The document'Intel® QuickAssist Technology Compression API Reference 2020' states that all CPA_DC_CHAIN modes are supported. But I don't know why it is not supported.

 

Also, unsupported values are set to'CPA_BITMAP_BIT_SET (bitmask, bit )'.

However, the error message'[error] dcChainSession_CheckSessionData()-: Invalid API Param-Unsupported operation 0 or 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or 9 or a or b or c' is displayed.

 

The QAT setting file for testing is as follows.

If you know how to fix it, please let me know. And is there any community site I can contact?

 

We are looking forward to your response.

Thank you.
