I am sorry, but responding with one page of hardware description is
totally unrelated to the code I am questioning here and does not make it
easier for me to respond. I understand that you want me to learn entire
new KVX architecture to be able to provide good review, but it is just
not possible, sorry. We all have quite limited time around here, so we
all expect concise and precise answers.

Best regards,
Krzysztof
