<albsen[m]>
on t14s, does this mean currently only 32gb out of the 64gb the machine has are addressable? "Boot issues with 64 GB version (disable upper 32 GB as workaround)"
<macc24>
i wonder why did they use an esp32 over something like stm32 or nrf
<craftyguy>
who doesn't want an EC that has its own wifi and BT stack? /s

I've got a very slow-moving project of a custom motherboard for thinkpad x61 and would probably pick an mcu with the best power saving features with rust embassy support

<SpieringsAE>
im pretty sure the esps have embassy support, but not in the actual embassy project
<SpieringsAE>
dont know much about their power saving modes though
<macc24>
grab these rules, with them i got hardware video decoding on sc7180
<macc24>
you'll also need a working kernel driver
<SpieringsAE>
ah I need to set up udev rules to make the hantro vpu work?
<macc24>
idk if it's in the ppa you were talking about
<macc24>
SpieringsAE: what
<macc24>
what hantro vpu
<SpieringsAE>
we have it in the imx8mp at work
<SpieringsAE>
in your rules file: ATTR{model}=="hantro-vpu", SYMLINK+="media-dec1", ENV{MEDIA_DEVICE_TYPE}="decoder"
<macc24>
it's to make chromium detect the vpu
<macc24>
it should work with ffmpeg and stuff without them
<SpieringsAE>
ah okay

cool thanks for that, will try when I get back to my laptop
<hogliux>
macc24: I'm the author of the ppa that landswipe was talking about
<hogliux>
I don't have any udev rules in there. It's just the driver. It's exposed as a v4l m2m device at `/dev/v4l/by-path/platform-aa00000.video-codec-video-index0`
<hogliux>
macc24: what does hantro mean in this context? On x1e, the video decoder is called venus.
<macc24>
hogliux: SpieringsAE was just asking a semi-related question
<hogliux>
ahh sorry

hantro is a different hardware enc/dec ip, which was in those rules by chance, but I know it from the nxp imx8m socs
<macc24>
it's there on purpose
<macc24>
those rules were borrowed from chromeos and mashed together to work on any cadmium-supported chromebook

<landwork>
bit green here, for this ppa (https://launchpad.net/~hogliux/+archive/ubuntu/yogaslim7x) how do I replace the existing packages? I know I can add the sources and "apt update" but if I try install the package (linux-qcom-x1e - obvious is already installed).
<hogliux>
then install packages in the following order: linux-modules-6.12.0-96-qcom-x1e_6.12.0-96.96_arm64.deb, linux-image-unsigned-6.12.0-96-qcom-x1e_6.12.0-96.96_arm64.deb, linux-modules-extra-6.12.0-96-qcom-x1e_6.12.0-96.96_arm64.deb, linux-qcom-x1e-headers-6.12.0-96_6.12.0-96.96_all.deb
<landwork>
I remember seeing I need an additional driver from the windows side too.
<hogliux>
Yes, exactly, you'll need `qcom/vpu/vpu30_p4.mbn`. On Windows it's called `qcvss8380.mbn` and it's usually found in `Windows/System32/DriverStore/FileRepository/qcdx8380.inf_arm64_90c8f1c486fcba86/`
<hogliux>
Note that there is already a vpu30_p4.mbn in Ubuntu concept but that is was signed for the CRDs and not for the slim 7x. robclark knows more on this.
<hogliux>
tobhe: Ahhh! I was editing all that manually. That was my first time creating a ppa package. So I'm a complete noob. Thanks for all your great work tobhe!
jelly has joined #aarch64-laptops
<tobhe>
now worries, happy to help :) it is all a little confusing sometimes
<landwork>
hogliux: is there a way to revert the packages if I installed them manually with "dpkg -i" ?
<hogliux>
landwork: I'll pass that onto tobhe
<tobhe>
landwork: you can just uninstall them with apt/dpkg when you don't need them anymore
<tobhe>
as long as there is another one installed
<landwork>
ok thanks :)
<landwork>
I installed hogliux's packages and updated the vpu30_p4.mbn from windows, so i'll reboot and see if I can get ffplay working now.

landwork: and.... does it work?
<landwork>
unfortunately no, the kernel just locked up
<landwork>
it had the boot splash though, so I couldn't really see what is going on
<landwork>
i just booted back to the earlier kernel, and it's still fine.
<tobhe>
you can press esc during the bootsplash to see the log
<landwork>
no, i'll try again... brb :)

pressing esc didn't work, i tried recovery mode, I could see it got through device tree, but just went black screen (similar thing in non-recovery).
<hogliux>
Interestingly, I actually never see the boot splash on Ubuntu Concept
<hogliux>
I only ever see the boot messages even though splash and quiet are set in the grub command line
<hogliux>
This is even after a fresh install of Ubuntu concept

re F23 scancode support: does anyone have some creative idea for what to use the Copilot key for? (other than just mapping it back to right Ctrl...)

the you can easily type Compose, C, C, C, P ☭ as one does
<landwork>
emoji key.
<landwork>
that might be quite useful on a laptop.
<landwork>
with shortcuts for common emoji (emoji+s) for smile.
<landwork>
even apple don't do this ;P
<jelly>
Compose : ) works already
<jelly>
a bit easier to remember than Ctrl+Shift+u, 263a, space

I commented GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" in /etc/defaults/grub to fix the splash
<landwork>
it seems to black screen after a bunch of i2c failures.
