What is the tplg firmware? I get `tplg firmware loading qcom/x1e80100/X1E80100-LENOVO-Yoga-Slim7x-tplg.bin failed -2`
<kuruczgy[m]>
Is it related to audio? Do I also need to extract this from Windows?

kuruczgy[m]: yes, it a file describing the audio topology for your machine
<jhovold>
someone needs to create one for your device as it's specific to linux
chrisl has joined #aarch64-laptops
<kuruczgy[m]>
Hm... I was under the impression that most yoga 7x owners here already got audio working, but I did not see this file in any of the firmware repos.
<kuruczgy[m]>
Could someone with working yoga 7x audio weigh in? What's your setup?
<jhovold>
iirc it was srini got the yoga up and running so he may have already created one
<pikkumunkki[m]>
jhovold thanks for the info! good to see you here, your tutorial helped me get the wwan working!
<pikkumunkki[m]>
tbh, if suspend works, i'll be perfectly happy with this laptop. the camera is not a big deal and i prefer to use my bt headphones anyways
chrisl has quit [Ping timeout: 480 seconds]
<jhovold>
suspend works even if the power consumption is too high, you get about 30h of suspend currently
<pikkumunkki[m]>
is there anything i'd need to enable for the suspend? when i close the lid, the led above the i in the thinkpad logo stays solid red, which makes me think it is not in susped
<jhovold>
it goes into suspend, but not the lowest power state
<pikkumunkki[m]>
and that's the reason why the led stays on?

jhovold: based on the windows device manager listing, the keyboard special keys appear to be on i2c9 (i2c8 on linux). haven't been able to enumerate it even as a raw i2c device though. any insights? I'm thinking it'll end up being a generic keyboard but I'm not sure if there's any hardware knowledge that would make this easier
<jhovold>
yeah, most likely, should be controlled by the embedded controller
<abby>
pikkumunkki[m]: it's s2idle
<jhovold>
abby: I have no idea, sorry, haven't looked at the EC at all
<abby>
np
chrisl has quit [Ping timeout: 480 seconds]
<jhovold>
abby: it looks like the only bus you can use to talk to the ec is i2c21 which we use for the keyboard and touchpad
<jhovold>
tz has another connection, so perhaps the special keys (e.g. mic mute) is exposed that way
<abby>
hmm
chrisl has joined #aarch64-laptops
<jhovold>
no, sorry, you're right, there's something on i2c8 as well
<abby>
on windows, the "lenovo something and fn keys" device is just a userspace driver that dispatches the various applications/actions on keypresses so i think it's just a keyboard, but based on the acpi address it's on i2c8
<jhovold>
that may very well be the case, nice digging
<abby>
maybe that doesn't cover mic mute but only the projector/thinkvantage/etc buttons

<Jasper[m]>
Is this on x13s?
<abby>
yes
<Jasper[m]>
I think konradybcio had some starting code to communicate with the ec for that stuff
<Jasper[m]>
Hadn't been able to try it since I don't have a buildenv. set up for that (for fedora kernels)
<Jasper[m]>
Both look to be to dump some data from the ec and not necessarily to make functionality work
<Jasper[m]>
He also asked to write down some stuff like what the state of the keys was before booting so he could see the difference before and after dumping
<abby>
saw that yeah
<Jasper[m]>
abby: Does confirm the i2c8 thing

i think I'll take more of a look today

An oservation on the HP X14: no firmwares except gpu loaded yet, loading the batery works regardless (charge led went from orange to white eventually).

Are there any docs for creating a USB boot drive for the x13s? I'm trying to use build a recovery "disk" using Synology Active Backup for Business. It doesn't have support for bootining in to the recovery tool on aarch64. I've gotten the recovery software working in HyperV on the x13s, but the image loses the usb drive when it tries to boot
rz has quit [Remote host closed the connection]
<JensGlathe[m]>
This sounds pretty odd. What is this recovery? Your Windows system or something else? For Windows it is quite normal to not work from USB if its the same system. This room is for Linux on aarch64 laptops afaict, though
<Jasper[m]>
<BrainWart> "Are there any docs for creating..." <- If you want to reinstall windows on the x13s ypu should be able to use the image creator Lenovo links on their site
<Jasper[m]>
s/ypu/you/
<BrainWart>
I'm hoping to recover windows with all of my files, etc. Once I get that working, I'd like to daily drive linux for a while again, but only after I get the custom recovery media working
<BrainWart>
"What is this recovery?" Its a hodge podge of qemu-system-x86_64, the WinPE environment, I can convince their software to build and passing through the drives.
<BrainWart>
I'm building the image for a Lenovo x13s
<JensGlathe[m]>
I have done recoveries from a complete sector-based backup by partition (minitool ShadowMaker) that worked. The target disk was removed from the X13s and connected via SSD enclosure, though. I could boot from it afterwards after completed recovery.
<JensGlathe[m]>
No idea if you can get ActiveBackup convinced to write to a physical disk from another machine

I've previously gone to linux and back using the arch linux ISO and doing a disk copy over the network to the NAS. ActiveBackup would be fine writing from another machine to the disk, I just wanted to be able to run it all on the one machine.
<BrainWart>
Would like to be able to build Linux images for the x13s in general too.
