Hi,
I have successfully installed the OCF on my DM814x system which enables the HW acceleration of the DSP. All the test code runs correctly and I get good performance.
But I cannot get it to work with buffers/files larger than 64K.
In cryptodev.h I can see that there is a limitation of CRYPTO_MAX_DATA_LEN (which is set to 64K-1) so I assume that this is the largest data size that can be processed per call to /dev/crypto but I cannot figure out how to split larger buffers into multiple calls into /dev/crypto in order to achieve the processing of larger buffers!
Can someone please help me get around this problem since I will typically have to get MD5/SHA-1/... for buffers larger than 1MB.
Best regards,
Karsten
