09:29 <SpieringsAE> What temperature does that happen at? I've not seen my asus get above 90 degrees, seems to chill at 88 degrees at full power. tbh I would like to make the fan curve a bit more aggressive, a bit too spicy for my liking

10:05 <SpieringsAE> btw whats happening with that qseecom allow list? My asus isn't on that list yet, but I saw something about making it generic for all x1e80100 systems so they don't have to be individually added

10:06 * travmurav[m] immediately wonders what's up with that on ufs devices like samsung

10:06 <travmurav[m]> I guess efivars are just readonly if you don't have qsee storage backend working

10:07 <SpieringsAE> there was someone that was making a patch for ufs

10:07 <SpieringsAE> but they are getting tired of revisions

10:07 <travmurav[m]> But they will appear writeable, just not save

10:07 <travmurav[m]> Oh fun

10:07 <travmurav[m]> Do you have a link?

10:07 <SpieringsAE> looking rn

10:08 <SpieringsAE> https://lore.kernel.org/all/p3mhtj2rp6y2ezuwpd2gu7dwx5cbckfu4s4pazcudi4j2wogtr@4yecb2bkeyms/

10:08 <travmurav[m]> Ah no i meant qhee/qsecapp specific stuff for ufs/rpmb based devices

10:09 <SpieringsAE> ah yeah no idea

10:09 srinik has joined #aarch64-laptops

10:09 <SpieringsAE> bit I was talking about this https://lore.kernel.org/all/20241103-rework-qseecom-v1-0-1d75d4eedc1e@linaro.org/

10:10 <SpieringsAE> I don't think it makes sense for me to make a patch to add my asus to the list if that is getting reworked

10:12 <travmurav[m]> Yeah I guess it sounds fine and we will just get someone asking why their efivars don't save later when everyone forgets xD

10:12 <travmurav[m]> Ah it was already brought up on the list even

10:12 <SpieringsAE> yep

10:13 <travmurav[m]> Well allegedly someone @ quic is looking into the qhee storage stuff so we will see i guess

10:14 <SpieringsAE> guess I'll be patient for now then, set everything I need to with my current kernel that has it enabled for the asus

10:14 <travmurav[m]> qsee, i always mix them up, eh...

10:16 <jenneron[m]> javierm: hi, can you change msm-cros-efs-loader fedora package to refer to the repo in our new gitlab instance https://gitlab.postmarketos.org/postmarketOS/msm-cros-efs-loader?

10:32 <Sayatomoki[m]> x13s usb-c dp alt mode can't output audio on kernel 6.11?

15:45 <wizzard> I'm trying to compile a kernel for Ubuntu with the latest patches for the 14s Gen 6, specifically to test some recent patches that enable external DisplayPort support. Currently, I'm running kernel version 6.11.0-49-qcom-x1e, but I noticed that the latest source is still on 6.11.0-48 (qcom-x1e-next) [link](https://code.launchpad.net/~ubuntu-concept/ubuntu/+source/linux/+git/oracular).

15:45 <wizzard> Hi everyone,

15:45 <wizzard> Could anyone clarify which branch is used for building the kernal and which I should be using to compile the kernel with the patches from qcom-x1e-next?

15:45 <wizzard> Here are the specific patches I'm interested in testing:

15:45 <wizzard> - [Patch for CPUFrec](https://lore.kernel.org/linux-devicetree/20241030130840.2890904-3-quic_sibis@quicinc.com/T/#u)

15:45 <wizzard> - [Patch for external DP support](https://git.launchpad.net/~ubuntu-concept/ubuntu/+source/linux/+git/oracular/commit/arch/arm64/boot/dts/qcom/x1e78100-lenovo-thinkpad-t14s.dts?h=qcom-x1e&id=432a0705d4ead617831e58f81810917236e0079a)

15:45 <wizzard> - [Patch for Sound](https://lore.kernel.org/all/d3431f6c-4fcf-4a8f-a33c-ac7e2994c6d9@oss.qualcomm.com/)

15:45 <wizzard> Thanks in advance for your help!

15:57 <tobhe> wizzard: let me actually push the latest tag

15:58 <tobhe> qcom-x1e branch is now in sync again

16:00 <tobhe> a few patches in the previous built caused regressions with the T14s oled and were reverted again until we find out how to fix those

16:01 <wizzard> Perfect. Thanks.

16:01 <wizzard> Any advise how to test the t14s: Add audio related nodes patch?

16:01 <wizzard> I am happy to help in debugging any issues.

16:11 <tobhe> the dtb changes alone are not enough to make the speakers work. We also need an audioreach topology binary and an alsa ucm config

21:12 <wizzard> Sorry for not knowing any better, this is the first time I am trying to compile a kernel myself. Which commands do you use to build the kernel from the qcom-x1e branch.

21:12 <wizzard> My build commands are:

21:12 <wizzard> I have followed the Ubuntu BuildYourOwnKernel Guide. First I appended a string to the version number in debian.qcom-x1e/changelog. Then applied my patches. I assumed I do not need change anything in menuconfig.

21:12 <wizzard> ```

21:12 <wizzard> fakeroot debian/rules clean

21:12 <wizzard> ```

21:12 <wizzard> fakeroot debian/rules binary-headers binary-generic binary-perarch

21:12 <wizzard> ```

21:12 <wizzard> The error is:

21:12 <wizzard> make: *** [debian/rules.d/2-binary-arch.mk:38: /home/liam/linux/debian/stamps/stamp-build-generic] Error 2

21:12 <wizzard> ```

21:12 <wizzard> These errors are cascading make errors, but they don't show the root cause. So I don't know what I am missing.

21:14 <abby> fyi irc doesn't have code blocks or multiline messages, best to use a pastebin if needed

21:18 <wizzard> Thanks for the advice.

21:20 <wizzard> Here is the paste for my previous message: https://privatebin.io/?0bfe1d5309dc49e5#D1UPKecW8q9tBEm8m6zbn38ndaNiFZrCPMHHN6oPAC59

21:23 <tobhe> I think a more up-to-date guide is on discourse, https://discourse.ubuntu.com/t/kernel-configuration-in-ubuntu/35857

21:25 <tobhe> oh and you need to replace generic with our kernel flavor name, qcom-x1e

21:26 <tobhe> so probably: fakeroot ./debian/rules binary-qcom-x1e

21:43 <craftyguy> Could someone please remind me how to press sysrq on the x13s? 😅

21:48 <abby> don't think that's currently possible, i think it's Fn+S or something

21:49 <abby> yeah Fn+S

21:49 <abby> doesn't work without the EC/extra keyboard keys that don't have a driver yet

21:50 <abby> https://download.lenovo.com/pccbbs/pubs/tp_13s_gen1/ug/html_en/index.html#t=en%2FUse_the_keyboard_shortcuts.html%23SpecialKeysForE420-FD0FF3311&rhtocid=_4_1_1

21:50 <craftyguy> Ah, I haven't seen this page before

21:51 <craftyguy> Ugh, welp, force poweroff/reboot it is then

21:51 <abby> can you get to a shell and do it in the sysfs sysrq?

21:52 <craftyguy> No, the internal display appears to be borked after a suspend/resume

21:52 <abby> ssh?

21:52 <craftyguy> Like, no backlight, and no access to external display or ssh

21:52 <abby> darn

21:53 <craftyguy> yeah. I know that suspend/resume while connected to an external display is broken, but every so often is seems to break for me when there is no external display involved

21:54 <craftyguy> bummer about sysrq key not working... what's this driver that needs to be made? Anything similar on other platforms?

21:57 <abby> a bunch of the fn-layer keys set registers in an i2c device, which i think from konrad's work is the EC

21:58 <abby> so something needs to match register changes <-> various events
