JensGlathe[m]: that seems to be it. If I `rmmod ath12k` before suspending then it does seem to suspend.

JosDehaes[m]: you should try unloading ath12k before suspending. At least in my kernel compilation test, I can see that it actually pausing compilation. Keyboard light still stays on though and the power indicator also does not pulse.

Here's an updated wip branch for x1e80100:
<JosDehaes[m]>
jhovold: great! Is the in-kernel pd-mapper still broken (x1e)?
<jhovold>
yep
ema has joined #aarch64-laptops
<JosDehaes[m]>
trying to use the userspace pd-mapper but it says: pd-mapper[623]: no pd maps available
<JosDehaes[m]>
qrtr-ns service is running
<jhovold>
JosDehaes[m]: missing json files? Or perhaps they are compressed?
<JosDehaes[m]>
where should I get those json files?
mrkajetanp has joined #aarch64-laptops
<jhovold>
from the windows installation along with the adsp (cdsp) fw
<jhovold>
they should go under /lib/firmware/qcom/x1e80100/
<JosDehaes[m]>
ah, thx!
<jhovold>
(e.g. adspua.jsn)
mrkajetanp has quit [Ping timeout: 480 seconds]
<JosDehaes[m]>
ok, so they had to be in /lib/firmware/qcom/x1e80100/LENOVO/83ED/
<JosDehaes[m]>
pd-mapper service is running now, but battery status is not working. I get synth uevent: /devices/platform/pmic-glink/pmic_glink.power-supply.0/power_supply/qcom-battmgr-ac: failed to send uevent in dmesg
<JosDehaes[m]>
something else missing?
<steev>
hogliux: the led pulsing is something from the EC and we don't have that yet
mrkajetanp has joined #aarch64-laptops
<JosDehaes[m]>
also power_supply qcom-battmgr-ac: uevent: failed to send synthetic uevent: -11
mrkajetanp has quit [Ping timeout: 480 seconds]
<jhovold>
JosDehaes[m]: not sure what that's about, perhaps your user space is doing something funny
<jhovold>
did you install the adsp fw as well?
<JosDehaes[m]>
yes
<JosDehaes[m]>
the .elf and the .mbn
<jhovold>
using the expected names? (they were unfortuantely renamed for the crd, not sure what machine you use)
<JosDehaes[m]>
I put 3 files adspr.jsn, adsps.jsn and adspua.jsn
<jhovold>
I suggest you verify that the remote procs are up, check the logs for any other errors
<jhovold>
and compare those names to what's in the dt
mrkajetanp has joined #aarch64-laptops
<JosDehaes[m]>
the firmware names match the DT
<JosDehaes[m]>
how to check the remote procs are up?
<jhovold>
JosDehaes[m]: you seem to be using some matrix quoting that shows up funny on irc, perhaps just you can just use regular quote chars (or a colon)
<JosDehaes[m]>
oh sorry
<jhovold>
dmesg | grep remoteproc
<jhovold>
remoteproc remoteproc0: remote processor 30000000.remoteproc is now up
<jhovold>
seems the driver does not receive the service up notification for some reason
mrkajetanp has joined #aarch64-laptops
<jhovold>
which kernel and config are you using?
<JosDehaes[m]>
using your -rc6 and your defconfig with some filesystems added
<jhovold>
which distro?
<JosDehaes[m]>
Arch
<jhovold>
hmm, not sure what to suggest then, similar setup to mine
<JosDehaes[m]>
I can try to build with a pristine defconfig
<jhovold>
ah, did you copy the battmgr.json file?
<jhovold>
jsn
<JosDehaes[m]>
ah no
<JosDehaes[m]>
also in same place?
<JosDehaes[m]>
from windows?
<jhovold>
yeah, that should be it

<kuruczgy[m]>
I saw the qrtr-ns service mentioned, what does it do? I don't have it, only pd-mapper, but battery status is working. Is it needed for something else?
<jhovold>
qrtr-ns used to be a user space service, but this is now implemented in the kernel (since years)
<jhovold>
the pd-mapper systemd files until recently depended on the user-space service to make sure either the kernel or user-space service was available
alfredo1 has joined #aarch64-laptops
<JosDehaes[m]>
oh, arch claims it's a dependency for pd-mapper
<kuruczgy[m]>
it's a build dependency sure but you don't need to run it as a separate service then apparently
<jhovold>
iirc, the user space daemon just refuses to start when support is in the kernel, but systemd thinks it's running
<jhovold>
as required by pd-mapper (up until recently)

hogliux: Interesting find. If I try to sleep during kernel compilation it refuses, the screen goes black for a second and then comes back, `/sys/power/state` reports "Device or resource busy", and I also see the "mhi mhi0: Requested to power ON" message.
<hogliux>
kuruczgyt: I only see the "Requested to power ON" message when I have ath12k driver loaded
<hogliux>
But looking at the IRC history here, I think I don't have all the firmware load patches for ath12k that you do
<hogliux>
But sleep is still intermittant: I tried compiling the kernel again over lunch break while suspended. The computer's screen went blank while I was packing things together, but when I came back the screen was on adn the kernel had finished compiling.
<hogliux>
Not sure what woke it. There was no "mhi mhi0: Requested to power ON" message.
<hogliux>
Instead of compiling the kernel, you can also just run something like this: I=0; while true; do echo ${I}; I=`expr ${I} + 1`; sleep 1; done
<kuruczgy>
For me the only wakeup source that seems to be working is the keyboard. E.g. I can't wake it up via the power button or the touchpad (and definitely not using the lid switch), only the keyboard.
<hogliux>
Maybe during my lunch break it never really went into suspend
<hogliux>
I think it's a bit hit&miss currently
<kuruczgy>
Your counter works as expected for me, it does not count during sleep.
<hogliux>
Yeah for me as well
<hogliux>
But then sometimes, it doesn't
<hogliux>
Not sure why. Seems a bit ransom. There seems to be kind of race condition somewhere.
<hogliux>
ransom=random
<hogliux>
kuruczgy: It should really work also during kernel compilation
<hogliux>
jhovold: I have a really general question: why doesn't booting with ACPI actually work? All the interaction with the EC is encoded into the ACPI tables which we can dump from Windows. I think Arm is pushing in that direction with their "Arm Base System" specification. And I think grub can load custom ACPI tables from disk.
<travmurav[m]>
hogliux: because most of the actual platform definition is not in acpi but in the PEP driver. Getting that to work in linux would be possible but /a lot/ of work, while DT support for qcom platforms in linux is pretty mature already thanks to mobile socs
<travmurav[m]>
I believe for some specific socs there was some work to make bare minimum work under acpi (iirc just usb and kb/tpad) but even that was only "so we can get installer to run far enough to put dtb in"
<travmurav[m]>
(though my personal opinion is that even that is too much work compared to letting installer images to carry the dtbs)

I've been tinkering a bit with an XPS 13 9345 (snapdragon). Just curious if anyone else has made any progress on that.

danielt has joined #aarch64-laptops
<danielt>
For Thinkpad X13s (with encrypted root), something seems to have changed between 6.10 and 6.11-rc6 that results in preventing the hexagons from booting (remoteproc cannot find firmware). Looking at the history here this seems to go back and forth depending on what modules end up being includes in the initramfs. Normally this gets solved by trying to find the module that needed remoteproc and forcing it to load later. That struck me as
<danielt>
pretty harmful to good distro support so I tried to solve it in Debian's initramfs-tools instead: https://gist.github.com/daniel-thompson/5475864aee6262200fee7b474202f0c3 . Still haven't decided if this approach is better or worse but is certainly makes my system work properly again.

I'm currently able to start grub using http boot, but it bombs out when I attempt to list the devices. In other strange news, when I disable the onboard disk and attempt to list the devices, I see ~100 partitions for a disk(hd0) that is probably some internal thing...or grub is confused about how to read devices.
<whiskey9>
*shrug* Just getting into grub seemed like a minor victory to me. heh
<robclark>
the windows laptops, you shouldn't need u-boot (but for the phones and other devices that use fastboot, you do)
<robclark>
re: extra partitions, IIRC some of the (earlier?) windows devices had extra partitions for firmware/etc.. and windows itself has some sort of recovery partition
<travmurav[m]>
50+ partitions would indeed sound like internal spi flash with firmware
<robclark>
right
<JensGlathe[m]>
Those are all EFI partitions(?) something like that, I see it when booting into EFI shell. I would try to boot with one of the already existing dt's.
<travmurav[m]>
and yeah, emmc devices have those right on the emmc, ufs devices can have it on a dedicated LUN
<JosDehaes[m]>
Yes, try with Jens' ubuntu image, my yoga booted with the CRD DT 2 months ago

also I heard bamse is working on the xps..
<whiskey9>
Sweet. Yeah, I'd be glad to compare notes with bamse, although I've been feeling around in the dark a bit, so my notes are...meh.
<JensGlathe[m]>
danielt: Nice script, a little more elegant than what I did (explicit list of all fw files to load). A few versions ago (6.8?) I fought with boot via type-c, and found the hack to disable the adsp fw on the rootfs so that loading it for whatever reason comes from initramfs. Otherwise I ended up with inaccessible rootfs and stalled boot. Maybe this was just a quirk/regression, I kept it in.
<\[m]>
is anybody still waiting on higher SKU cpu for thinkpad t14s?
<JensGlathe[m]>
I am waiting on the Snapdragon Devkit
<JensGlathe[m]>
as a backup strategy I got a HP Omnibook X14
<JensGlathe[m]>
on ebay
<HdkR>
psref still doesn't claim that T14s will have a higher end SKU
<HdkR>
Which considering the system load I can get out of abusing the CPU cores, I don't blame them
<\[m]>
yeah I called them again, the sales said that since the laptops are selling less than foreseen probably there will be no more investment in extending the lineup
<\[m]>
where are those devkits anyway lol
<\[m]>
next day delivery !! a day means a year loloops
<nirik>
Anyhow happen to have the pm-mapper json files for the slim7x up anywhere? Getting them from windows means I would have to swap that nvme back in, which is a pain. ;)

<\[m]>
only samsung and dell have faster ones
<JensGlathe[m]>
\: Jasper exactly. I can do tests now

I like dell laptops better than hpe - but maybe it's not the same as the ones corpo gives you
<\[m]>
you have the dts?
<\[m]>
the dell has a weird laptop hinge though, it's like made to cut off your leg bloodstream haha
<JensGlathe[m]>
No. So that's first thing to do. I would have preferred T14s, but the price puts me a little off
<HdkR>
Nice. My T14s arrives in a couple of days, so hopefully I can set it up with those external DP patches and get some footage

stupid question, what games besides Minecraft can be run on the 8cx Gen 3 on Linux?
<robclark>
nirik: and external dp.. but hopefully it is wired up similarly to t14s?
<nirik>
ah yeah, I did try HDMI out here a while ago with no luck, I assume related?
<robclark>
nirik: the in-kernel pd-mapper can load compressed jsn (but apparently has some issues.. that I've been lucky enough to not hit).. probably the userspace pd-mapper was retired from rawhide because kernel on is the $future (modulo $issues)
<robclark>
yeah, probably
<nirik>
I can try rebooting without the userspace pd-mapper now that I have the jsn in place and see if it works...
<nirik>
I do see these (possibly related to not working things?):
<robclark>
main issue w/ userspace pd-mapper vs how fedora (and I think others) handle linux-firmware is that userspace pd-mapper can't grok compressed jsn.. I guess there is a known issue that jhovold hits with kernel pd-mapper which (AFAIU) is due to order things load.. I guess I don't end up with those modules in initrd so things load late enough to not be a problem for me

Does anybody have more details on how BT is connected on x1e80100 laptops? Is it part of the ath12k module or part of the SoC? Is it connected via some internal bus? I'll have a look at the ACPI tables and see if I spot anything there.

Most laptops just have WCN7851 which handles both WiFi and BT. It is connected via PCIe (WiFi) and UART/SLIMbus (Bluetooth)
<JensGlathe[m]>
The HP Omnibook X14 booted with the ASUS Vivobook S15 dt to GUI, apparently stable- just set the sys up, did updates and rebooted
<JensGlathe[m]>
Getting into grub was sorta tricky, F11 -> Recovery screen from Windows -> Esc to get BIOS boot menus, select external USB - find no kb working, so it boots the last selected entry
<JensGlathe[m]>
This one has a WCN6855 WiFi 6E / BT
<JensGlathe[m]>
type-c connectors are working, type-a not yet
<JensGlathe[m]>
internal kb not, internal touchpad does
<JensGlathe[m]>
Curious how it goes with rc6
<anonymix007[m]>
Does it have M.2 key E slot for Wi-Fi/BT?
<JensGlathe[m]>
not looked iinto it physically yet, it says QCNFA765 on 0004:01:00.0
<JensGlathe[m]>
so its the same as in X13s and Volterra (sorta), has different board id
<JensGlathe[m]>
I slightly remember bluerise asking about this one
<JensGlathe[m]>
Now its running with USB Ethernet adapter via type-c hub. At USB3 speeds (when plugged in upside down, interesting. Same for the USB SSD)
<JensGlathe[m]>
There are SKUs where you get it with ATH12K
<JensGlathe[m]>
so, whatever form factor these cards have
<anonymix007[m]>
There is a YouTube review of the OmniBook and it appears to have an M.2 slot.
