07:29 <ungeskriptet> dianders: I remember on my first attempt to get the touchscreen working I had to add a 1 second sleep before it tries to read the version. But that was before I realized this touch IC supports i2c-hid and therefore was using the normal goodix driver. Making it sleep in the i2c-hid driver right before the read does not make a difference sadly

07:30 <ungeskriptet> With the normal goodix driver I actually had the pen and touch partially working

07:32 <ungeskriptet> Maybe there are multiple modes that this IC has? Like one uses a proprietary I2C protocol and the other i2c-hid. Is that possible?

08:12 <dianders> ungeskriptet: Sorry, I just don't know. ...but it feels unlikely that it would support both. I've never seen it, anyway. If it was sorta working with the non-i2c-hid driver then are you sure it's supposed to support i2c-hid?

08:19 <ungeskriptet> dianders: The datasheet mentions that it supports i2c-hid https://archive.org/download/goodix-datasheets/GT7385P%20Datasheet.pdf

08:19 <dianders> ...and how certain are you that this is the touchscreen you have on your hardware?

08:23 <ungeskriptet> Well, I know that it should be some sort of GT738X from the device tree. The panel datasheet says that it is GT7385P and the cfg file for the driver has the string "7386" in it

08:26 <ungeskriptet> Hm, I guess I have to look inside to be certain. I have a x86 tablet that also has a Goodix IC which identifies itself as "GXTP7386" in the ACPI tables but is actually GT7382H. That one supports i2c-hid

08:27 <dianders> ungeskriptet: FWIW, the GT7375P datasheet I have (in English) has _a lot_ more details about hid-i2c in it. The one you pointed at in Chinese only says hid-i2c once. Any chance it's just a paste-o where they forgot to delete it from some other touchscreen that supports i2c-hid?

08:29 <ungeskriptet> The GT7385P datasheet does indeed seem to be very similar to the GT7375P datasheet I found

08:33 <ungeskriptet> dianders: Does your datasheet mention GT738?

08:39 <dianders> ungeskriptet: no, doesn't mention GT738

09:04 <krzk_> now you see who is true to the IRC :)

09:08 <ungeskriptet> Matrix ded?

11:03 <ungeskriptet> dianders: So someone took their tablet apart and it definitely is GT7385P

16:59 <enyalios> oof, i was running grub-install and my x13s crashed

16:59 <enyalios> and it would no longer boot at all

16:59 <enyalios> i had to make a usb boot drive, boot off of that, chroot into my os on disk and reinstall grub from there to fix it

17:39 <ungeskriptet> This is so weird, I switched to the normal goodix driver and touch and pen input gets detected...

17:39 <ungeskriptet> Although not correctly

17:46 <ungeskriptet> dianders: Would it be possible for you to share the datasheet to me? And if not, does the datasheet mention anything about firmware? I'm thinking that they might have disabled i2c-hid through firmware

18:37 <zdykstra> enyalios: I've had a crash when manipulating efivars via efibootmgr, I wonder if you hit the same underlying issue with grub-install

18:39 <enyalios> zdykstra: yeah im pretty sure the crash was due to efivars stuff

18:40 <abby> i think there's a patch floating around for that

19:02 <steev> there is

19:02 <enyalios> yeah im still on 6.7.0 because i like how much louder audio is
