17:41 <hanguofu> Hi , there : I would like to try the HW decoding feature at Amlogic s905x cpu with kernel 5.x . Is this feature avail. at the current mainstream linux kernel now ?

19:22 <Darkmatter66> xdarklight, Hi, I tried to use the odroid c2 ethmac node on my device to test for the interrupt as you suggested

19:22 <Darkmatter66> xdarklight, I can see the number increases rapidly even without unplugging and plugging the cable

19:36 <xdarklight> Darkmatter66: then either a different GPIO is used or the PHY interrupt is not routed to the SoC at all (both are possible)

19:37 <xdarklight> Darkmatter66: thank you for trying though :)

19:43 <Darkmatter66> xdarklight, is it possible to investigate the gpio without having the schematics ? I'm guessing your answer will be no lol :)

19:45 <xdarklight> Darkmatter66: I considered doing an experiment on one of my own boards but never tried it. it goes like this: switch all GPIOs to input mode, enable the PHY interrupt and ACK it. now dump the status of all GPIOs. unplug the Ethernet cable and dump the status of all GPIOs again

19:45 <xdarklight> then diff the two GPIO register dumps and try to make sense of it ;)

19:48 <Darkmatter66> xdarklight, seems a bit over my skills in kernel hacking but it makes sense, if you have more details steps and code I would be happy to try it(now or in the future)
