10:27 <crossdev> Trying to get cpu temperature on Orange Pi 5 with mainline kernel 6.8.1 . I have CONFIG_HWMON=y , CONFIG_ROCKCHIP_THERMAL=y but nothing pertaining to the cpu in /sys/class/thermal or /sys/class/virtual , what am I missing?

11:11 <FergusL> Can a gadget device connect to its host through a hub? I've always assumed no, but maybe it can because usb is black magic after all! That would solve my slightly hopeless attempts with this on my rk3326 devices

11:25 <robmur01> can't recall for sure if I used my hub when I played with gadget mode on RK3328, but I don't think there's any reason it shouldn't work

12:04 <FergusL> robmur01 did you get gadget mode to work? assuming 3328 is very similar to px30 as well

15:11 <robmur01> FergusL: yup, with my NanoPi R2S - IIRC I got g_serial working as a console via command-line, and g_mass_storage probably via its module parameters (don't think I touched configfs)

15:12 <robmur01> I don't recall touching the DT, but it's possible given that the upstream one has dr_mode forced to "host"

15:22 <FergusL> robmur01 thanks, interesting to know legacy gadget works! Do you remember having to fiddle with this? https://github.com/torvalds/linux/blob/master/drivers/usb/dwc2/Kconfig#L39 namely forcing a specific role in config, this is the only thing that just got gadget to work for me on mainline, just had success with that today

15:23 <FergusL> qschulz ^ tagging you here as we were talking about that the other day and it seems I finally had some success

15:24 <FergusL> I set usb_dwc2 t to USB_DWC2_PERIPHERAL. It's not ideal at all ofc since it's forced in driver but at least that's proof it works. I tried with mtp and cdc

15:25 <FergusL> Using configfs

15:25 <qschulz> FergusL: yeah I am not really interested in that, this is not ok for distro kernels :/

15:26 <qschulz> but thanks for the heads up, I am not surprised so I may have played with this a couple of years ago but had forgotten about it :)

15:30 <robmur01> Indeed, I wouldn't have used that driver config either, even if I wasn't using a stock distro kernel (which was most likely the case)

15:35 <FergusL> let me guess, a lightweight home router?

15:47 <FergusL> interesting, the R2S page explicitly documents the USB-C as power + "slave" port, I guess that's the port you used. Was it on mainline or bsp back then?

16:34 <robmur01> Hmm, actually that might have been the time I also had the wrong SD card with me, so it could have been a fresh BSP image rather than my usual distro...

16:34 <FergusL> and I agree it's not ok, it's just that the last feedback I got from here was that it was "broken", so my hopes were pretty low so I went for the last resort solutions :) Now that I know that mainline can work in some configuration I can at least look at the code fenced out by PERIPHERAL/DUAL_ROLE ifdefs and maybe get an idea of what isn't working

16:35 <robmur01> mine's the original one with a micro-B port, so really not much use as a host unless you were to contrive some kind of unholy cable ;)

16:35 <FergusL> the dmesg I got when it worked had a bunch or core reset before it started working whereas when it didn't work it didn't even report any attempt to reset

16:36 <robmur01> at this point I suspect I will end up having a play tonight or tomorrow, and report back :)

16:36 <FergusL> oh yes, it had micro-usb before

16:36 <FergusL> thanks so much for taking the time :)

16:37 <FergusL> fyi I'm using this device: https://jelos.org/devices/unbranded/game-console-r35s-r36s/

16:37 <FergusL> and this distro, too

16:55 <qschulz> FergusL: please lemme know if you figure some things out :) I can always test on our Ringneck PX30 if needed :)

17:30 <ianh> crossdev: more ideas - CONFIG_THERMAL_OF, CONFIG_THERMAL_HWMON, CONFIG_CPU_THERMAL, CONFIG_THERMAL, etc.

17:33 <ianh> from commit history it looks like the rockchip-thermal driver supports rk3588(s) as of 6.8...

17:50 <qschulz> ianh: IIRC the DT node is tsadc for that kind of things? Did you check that driver is enabled both in DT and in your config?

19:29 <crossdev> ianh: thanks for tips, I revised, compiled in anything that had THERMAL in it, the entire ACPI too, no joy. Weird.

20:26 <ianh_> qschulz: yea i took a look earlier and the tsadc stuff is definitely in there and accurate for the rk3588s dtsi referenced by the opi5 dts. module looks good too.
