How to poll cpaCyRsaDecrypt operations?

BKlis — Fri, 18 Sep 2015 19:15:34 GMT

I am working on a user space application that requires asynchronous RSA operations. I believe I have the option between receiving an interrupt callback or polling for completion of the operation. I'd like to use the polling method to avoid the context switching of the interrupt callback.

I do observe that by toggling the "Cy0IsPolled =" between 1 and 0 in the /etc/dh895xcc_qa_dev0.conf I can influence whether icp_sal_CyPollInstance returns a CPA_STATUS_SUCCESS when the operation is complete, so that looks good.

However, I am finding that I always must include a valid callback to the second parameter (psRsaDecryptCb) of cpaCyRsaDecrypt in order to use that API asynchronously and that callback is always invoked regardless of the "Cy0IsPolled" value in the configuration file.

What is the correct configuration to work in a polling-only mode so I don't get the callback?

Hello,

No, the information is not useful to me as both links in your reply seem to be broken. Is the Software Networking Forum part of this "Embedded Community" site? I see only the following forums.

/community/en/hottopics Moderator Top Picks

/community/en/hardware Hardware

/community/en/software Software & Bios

/community/en/applications Market Applications

I was originally pointed to this site from representative in my area.
