> What do you think about adding some more HW entropy consumers? Yeah, that would be good. Do you have any suggestions? I'm actually not very familiar with which blocks...
I've changed the ISR implementation to collect the whole 1024 buffer and dump it if there were any overflows to ensure contiguous samples, but it's slowed the test way down....
I guess the problem is that if we push 512 bytes on the first interrupt and then get an overflow, we can't take back those 512 bytes that we already...
Just so I'm understanding, are you saying to have the read ISR push small amounts of data into an in-memory buffer so that the observe FIFO doesn't overflow, then have...
I tried that with an ISR that blocked and wrote the whole buffer of 1024 to the conditioner in one go and it was too slow. I could try again...
I've updated the implementation to read and write 32 words at a time in each interrupt while still handling overflows. This runs a lot faster. It's triggered by the "entropy...
Sorry for the delay, I've added some usage of AES, KMAC, and HMAC. Please let me know if my usage of them isn't sufficient. I didn't copy all of the...
I have moved some functions to `testutils`, fixed up some comments, changed some flags, and swapped HMAC for OTBN.
I think the changes that will be needed for the backport are: 1. The workaround for the observe FIFO overflow will need to be added back. 2. OTBN required the...
I'm not sure if this is worth raising here but I just started trying the frontmatter syntax and had the following problem: The current syntax of a script does not...
