kuruczgy[m]: Well, even in EL2, the adsp "lite" firmware loaded by UEFI will still be running unless you stop that. So it will still be somewhat involved in USB-C negotiation, even if Linux doesn't talk to it anymore
chrisl has joined #aarch64-laptops
<kuruczgy[m]>
sgerhold: I have your patch so it should talk, no?
<sgerhold>
kuruczgy[m]: right, then your "It can't be adsp since in EL2 no adsp fw loading should be happening anyway." sentence is still wrong though :)
<sgerhold>
you have the lite adsp running :)
<JensGlathe[m]>
Does it mean we need to look somewhere else?
<kuruczgy[m]>
I meant that there is no difference between initramfs and non-initramfs since both will be running the lite adsp fw
chrisl has quit [Ping timeout: 480 seconds]
<JensGlathe[m]>
Looks like some module might be missing...? drm_dp_aux is built-in in my config afaict.
<sgerhold>
kuruczgy[m]: hm it will still behave weirdly, like the USB disconnects happening when trying to boot from USB and the adsp is enabled
<sgerhold>
I think even with the "lite" firmware thing you get the disconnects
<JensGlathe[m]>
by reattaching to it?
<sgerhold>
yes
<sgerhold>
I haven't managed to track down where they come from, only tested this for a couple of minutes though
<JensGlathe[m]>
So it will invalidate the already negotiated DP Altmode stuff, too?
<sgerhold>
that's likely, yes
<JensGlathe[m]>
And we have sort of no way to time this better I guess
<kuruczgy[m]>
Hm... if the usb disconnection theory is correct then the bug should probably still manifest when all dp relevant modules are present in initramfs.
<kuruczgy[m]>
I should try that
<sgerhold>
kuruczgy[m]: which modules do you have in initramfs at the moment? (display ones, in particular)
<JensGlathe[m]>
On the SnaDragon DevKit and on Purwa, you need to avoid type-c until fully booted up in my experience. Boot from type-a or nvme works, display comes pretty late on the Dev Kit (because DP Altmode, and not consistent - re-plug usually works).
<kuruczgy[m]>
sgerhold: I can post the full list + the kernel config (to see what's builtin) in the evening
<sgerhold>
kuruczgy[m]: sure. To make comparison easier it would be good to use Johan's kernel config as a base (and avoid messing with the builtin/module there)
<kuruczgy[m]>
I am :) But I have no idea if the NixOS build system is overriding anything, we will see.
<Grabunhold>
just upgraded my x13s to Fedora42. haven't used the system for anything meaningful yet, but so far it looks good. upgrade went as smooth as on amd64, system boots to the desktop, no obvious regressions so far. great!

<kbingham>
Grabunhold, are you using the stock F42 kernel?
<kbingham>
I have Full Disk Encryption enabled, and so far I can only use self built kernels - Curious if anyone else has working Fedora with FDE (and a stock Fedora kernel)
ravikant_ has quit []
<Grabunhold>
kbingham: i'm using the stock kernel with the kernel cmdline options prescribed by the wiki, yes. i do use disk encryption, but i guess it depends on your definition of "full". I'm not encrypting /boot or /boot/efi
<Grabunhold>
but my root partition is encrypted

(i guess encrypting /boot/efi would only be possible by using OPAL or whatever the nvme-integrated encryption is called. but i don't trust nvme firmware, so it's not an option)
<JensGlathe[m]>
<\[m]> "I hope it makes the gen 1..." <- They try to sell the X1e designs with Purwa SoCs now at nearly the same price point, as it seems
<kuruczgy[m]>
By the way how difficult DP MST support is expected to be on x1e? (AFAIU it's needed for any USB-C dock that offers multiple display outputs, right?)
<kuruczgy[m]>
Is it mostly straightforward and someone just needs to sit down and implement it, or is it seriously blocked by lack of hardware documentation?

Status update: 6.15.0-rc4-jg-0 appears to be a major step forward in stability, DevKit hasn't rebooted since, despite quite rough handling. Will test again with the odd RTL8125 card. Also got the I226V m.2 a+e-key card, let's see.

steev: Have you build 6.14.4 Kernel for your x13s but have it not pushed it to your web-site? On your Web-Site ist still 6.14.1.
<steev>
correct, sorry, been using my 2017 macbook pro the past few weeks because i needed to test something with /dev/kvm
<steev>
will probably get around to it this week (or probably, .5 will drop this week and get to that one)
<agl>
ok
<agl>
test
<agl>
sorry

I just did an update of linux-firmware. Looks like it breaks WLAN on the T14s (using jhovold 6.15-rc4). Reverting to older firmware fixes the problem.

try using the firmware from Windows. sometimes the firmware file has abi changes and you need a new board file too.
<tstachecki>
I'm running a wcn7xxx firmware from 08/2024 on the SL7 and 6.14
