Hi, Commit c8377adfa78103be5380200eb9dab764d7ca890e ("PM / wakeup: Show wakeup sources stats in sysfs") is causing some of our tests to fail because /sys/class/net/*/device/power/wakeup_count is now 0, despite /sys/kernel/debug/wakeup_sources clearly indicating that the Ethernet device was responsible for system wake-up.
What's more in looking at /sys/class/wakekup/wakeup2/event_count, we have the number of Wake-on-LAN wakeups recorded properly, but wakeup_count is desperately 0, why is that? This is seen on 5.4.43, but it is reproducible on Linus' master as well. The Ethernet driver being used is under drivers/net/ethernet/broadcom/genet/ and the relevant part is in the function bcmgenet_set_wol(). BTW, I think you want to backport e976eb4b91e906f20ec25b20c152d53c472fc3fd ("PM: wakeup: Show statistics for deleted wakeup sources again") into 5.4 and 4.19 at least. Thank you! -- Florian
