It's not clear to me if ARM (the company) is actually interested in pursuing Cheri since all the work seems to have been DARPA or UK gov funded. I'm more interested in their RISC-V implementation (FPGA only for now I think). Some companies might be able to run with RISC-V and give us real hardware.

Are you suggesting this year will be the end of their Morello program? From [1] "The Morello program started in October 2019, and will span a 5-year period." [1] https://www.arm.com/zh-TW/architecture/cpu/morello https://www.arm.com/zh-TW/architecture/cpu/morello

  I am not sure what your comment means. We are almost 5 years past Oct 2019, are we not? If that’s what you intended to point out, I am sorry.

      Again, it's just better if you say what you're trying to say, instead of posting a bunch of links and let us figure it out. I don't know how any of your links really let us weigh ARM's commitment to CHERI going forward, which is the point of discussion. Indeed, none of those 3 links has anything to do with ARM at all, other than the first mentioning Morello. The comment you responded to is this: > It's not clear to me if ARM (the company) is actually interested in pursuing Cheri

        It is the commitment of Microsoft Research dollars.

        We're discussing whether this is a likely future direction for ARM, and whether ARM will continue to invest in this or push this as a key future direction. That is what you replied to. You've shown nothing other than ARM was interested in taking some research money in the past. And, frankly, you've wasted my time with links trying to figure out what you were saying (which turned out to be irrelevant). Sigh.

        ARM will be interested as long as Microsoft Research is interested in putting in the greens. Please don't waste more of your precious time replying to this.

        The question was whether ARM was interested in this beyond collecting research dollars.
