00:18 <bamse> Mis012[m]: i unfortunately don't know what the intended audience for the "flat" files are, so i don't know

08:16 <Marijn[m]> <bamse> "and what i suggested above was..." <- Having an interrupt parent instead of hardcoding/repeating the USID seems nicer regardless of this issue tbh

08:25 <Robbbbbb> Hi all, I'm working on porting mainline linux to the Oneplus 9 (SM8350) and I'm trying to bring up the modem. So far I've updated the DT to enable the modem nodes and add the firmware (https://github.com/ElRoberto538/linux/blob/sm8350/arch/arm64/boot/dts/qcom/sm8350-oneplus-lemonade.dts), if I ssh in and install pd-mapper, tqftpserv, qrtr & rmtfs, enable them all and reboot I can see a timeout error in dmesg as it tries to bri

08:26 <Robbbbbb> Are there any obvious steps I'm missing? Do newer modems from qcom require mba.mbn? I couldn't find it on my downstream device and I don't see any device past the SDM845 using it

08:31 <z3ntu> Robbbbbb: On sm6350 (also relatively new but not as new as 8350) I only have modem.mdt & modem.b*

08:31 <z3ntu> And please share the exact error message

08:31 <Robbbbbb> qcom_q6v5_pas 4080000.remoteproc: start timed out

08:32 <Robbbbbb> remoteproc remoteproc0: can't start rproc 4080000.remoteproc: -110 [ 18.705056] remoteproc remoteproc0: Boot failed: -110

08:33 <Robbbbbb> Also:

08:33 <Robbbbbb> oneplus-lemonade:~$ qrtr-lookup Service Version Instance Node Port 14 1 0 1 14 Remote file system service 4096 1 0 1 16386 <unknown> 15 1 64 10 1 Test service 43 2 23 10 2 Subsystem control service 66 1 76 10 3 Service registry notification service 51 1 13 10 6 CoreSight remote

08:34 <Robbbbbb> Ah sorry never used IRC, not sure how to format correctly. qrtr lookup is showing some services as cdsp.mbn seems to load as remoteproc1 correctly

08:36 <z3ntu> Why do you have `mcfg_hw.mbn` referenced in your dts?

08:37 <lumag_> Robbbbbb, use pastebin to post formatted text

08:38 <Robbbbbb> I was mashing around seeing if I could get it to do anything differently. Need to push my revert of that

08:40 <z3ntu> and you're sure your modem.mbn comes from the stock software? It very likely needs to be correctly signed so that it boots

08:40 <z3ntu> by oneplus in your example

08:42 <Robbbbbb> Hmm, It did come from the same device I am porting, but It was modem.mdt (and co-files) and I used pil-squasher to squash them into an mbn file.

08:44 <z3ntu> that should leave the signature intact so should be ok

08:44 <Robbbbbb> Can you link your work on the sm6350? Would be good to compare and see if i'm missing something

08:45 <z3ntu> Robbbbbb: https://github.com/torvalds/linux/commit/489be59b635ba76ea16d6f820ddf037644b3415a & https://github.com/torvalds/linux/commit/bc279dc04e9ee23f6a22f6c7a6924edbd5fe0f6d

08:46 <z3ntu> Also check outputs of the user space services, especially rmtfs & tqftpserv

08:47 <Robbbbbb> thanks will have a read. Also stupid question, how do I get irc to show the chat history when I connect, need to go soon and closing this https://webchat.oftc.net page looses all history on re-connect

08:47 <z3ntu> An IRC bouncer is used for that, but you also have a matrix account you can join via https://matrix.to/#/#_oftc_#linux-msm:matrix.org

08:50 <robbbbbb[m]> Cool thanks, will double check the output of the services, I was working on it a couple of weeks ago and I remember them looking good, the only error I can see is that timeout error from dmesg

10:23 <Mis012[m]> bamse: it is my understanding that the FLAT is generated based on HDL, so presumably the register is specified as having one 32bit field for some reason

10:26 <Mis012[m]> one possible explanation for being defined weirdly is if it's some sort of bypass that allows accessing stuff inside the SSC block without the AHB bus being operational, but that's just wild speculation
