Yeah, "Qualcomm" is one of those places information never gets out of, right? This might turn out to be "influenced by RISC-V" but completely different actual instructions; with the NDA and lien on your soul before you can even sniff documentation .
RISC-V is the ISA plus some auxiliary specs. A CPU, and even more so a SoC, contains enough other stuff that Qualcomm can torment their partners (and their lawyers) with. And of course they will do that.
Qualcomm is a patent troll. They probably already have a few dozen over-broad patents on things crucial for RISC-V implementations and are just fishing for more.
They (alongside every other member) signed an agreement with the RISC-V consortium that limits them on what funny business they can do.
