11:48 <mwalle> NishanthMenon: did you see my mail regarding the assigned-clocks property? I don't think that is the culprit.

11:49 <NishanthMenon> mwalle: yes - tifs firmware will report 0 clk till the IP is activated

11:50 <mwalle> NishanthMenon: till the clock is enabled. but the real problem is caching (or rather when linux is caching the value) in linux

11:51 <mwalle> set_clock will just work fine. it's the TIFS will just mask the clock frequency (which is probably a stuid thing to do :o)

11:51 <mwalle> but that's another topic ;)

11:53 <mwalle> NishanthMenon: in short, I don't think the workaround i've posted (and that is in OOT driver) is correct

11:53 <mwalle> It looks like the clock driver has to be fixed

11:55 <NishanthMenon> vigneshr: ^^ can one of our power people look at this?

11:55 <mwalle> Though I don't have an idea right now how to do it. Except the NO_CACHING flag. Not sure how expensive that is, because it will propbably affect any clock

11:55 <NishanthMenon> mwalle: I suspect it might be expensive

11:56 <mwalle> NishanthMenon: I don't have any clue how linux is communicating with TIFS ;)

11:59 <NishanthMenon> From internal diagram (been a few years.. but i think this is till mostly valid.. reset - i think goes through psci now) https://usercontent.irccloud-cdn.com/file/AMmj4paT/image.png

12:01 <mwalle> NishanthMenon: For an outsider, thats rather hard to read. But apparently it goes through some kind of hardware mailbox between the cpu cores

12:01 <mwalle> also I assume "Framework IRQDomain" and genpd etc are the linux subsyss

12:02 <NishanthMenon> correct - it is a mailbox (a bit advanced version with DoS protection) that is used to communicate with Device manager for services. and yes, the CCF etc are linux frameworks

12:03 <NishanthMenon> this is more less the same if you see other protocols like scmi etc.. (sigh.. wish scmi was a little more scalable and safety concious, we would have switched to that)

12:25 <mwalle> Did you experience failures with TIs mails delivery system? I just got "The recipient's mailbox is full and can't accept messages now. Please try resending your message later". Quite funny :o

12:26 <mwalle> (Jayesh mailbox)

12:27 <mwalle> I also like how i get the mangled (internal) mail attached to the report *gg*

12:31 <NishanthMenon> mwalle: Jayesh is no longer with TI

12:31 <NishanthMenon> they do leave the mailbox active for some reason - i think it does get cleaned up later.. but it is irritating..

12:49 <mwalle> NishanthMenon: ok
