* Power supply detection issue caused by ucsi_psy? @ 2020-11-09 10:48 Vladimir Yerilov 2020-11-09 11:20 ` Heikki Krogerus 0 siblings, 1 reply; 8+ messages in thread From: Vladimir Yerilov @ 2020-11-09 10:48 UTC (permalink / raw) To: linux-usb, Heikki Krogerus, Greg KH [-- Attachment #1: Type: text/plain, Size: 1389 bytes --] Good day everyone, Since linux 5.8 I'm experiencing a problem related to power source detection on my laptop. My machine is equipped with 2 typec ports, one of them has power delivery and is used for charging, another one has only data transfer capability. The issue is, when I unplug the power cable, the OS is reporting something like "Battery at 100%, plugged in but still discharging" (KDE Plasma notification) - whether another port is used or not. I checked with upower, you can see the output for kernel 5.4 and 5.10 attached. In brief, on 5.8 onwards I have some "line_power_ucsi_source_psy_USBC000o001" device which is considered a power supply and that prevents OS to switch to "battery mode" when unplugging the cable, instead it thinks there's a power source but not powerful enough to charge the battery, upower says this: "on-battery: no", but actually no ac power source is connected. I did some research with git bisect up to the merge commit `e611c0fe318c6d6827ee2bba660fbc23cf73f7dc` ("Merge tag 'usb-5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb"), and looked through its content. My wild guess based on upower output is that a new driver introduced there, /drivers/usb/typec/ucsi/psy.c, is responsible for this wrong behavior. Could you please look into that based on info I'm providing?

What machine/model are you seeing this on? The PPM is implemented in Firmware, so the behaviour will depend on the Vendor or even model. I observed it on a Lenovo laptop, but would be curious to know if similar issues happen elsewhere. I only observed an issue when using a thunderbolt dock and not with a plain USB-C charger. > Can you try the two patches from that series? Yeah, that would be a good data point.

To: Benjamin Berg <bberg@redhat.com> Hi Benjamin and all, Unfortunately, these patches had no effect on my side. The OS still thinks there's some power source called "/org/freedesktop/UPower/devices/line_power_ucsi_source_psy_USBC000o001" when there's actually no cables attached. I used 5.10-rc3 as base with your patches applied on top of it. пн, 9 нояб. 2020 г. в 21:36, Benjamin Berg <bberg@redhat.com>: > > Hi, > > On Mon, 2020-11-09 at 13:20 +0200, Heikki Krogerus wrote: > > On Mon, Nov 09, 2020 at 08:48:06PM +1000, Vladimir Yerilov wrote: > > > Since linux 5.8 I'm experiencing a problem related to power source > > > detection on my laptop.
