<steev> "i'm curious if anything from..." <- maybe? you can check if there's the same "ac adapter status" register
<macc24>
or just see if it's mentioned in dsdt

Jasper[m]: nice work! even if we can't access it directly from linux, it opens up the path for using the dtbloader as travmurav[m] mentioned

where is chromeos's firmware at /lib/firmware/sc7180-trogdor/modem/*.mbn even fetched from? i've looked for it in every place i could think of and couldn't find it anywhere - only on the chromeos recovery medium
<travmurav[m]>
Iirc it was never upstreamed
<macc24>
i looked in the chromiumos repos on googlesource
<amstan>
macc24: it was an internal ebuild only
<macc24>
ugh
<amstan>
the vendor liked it better that way since "nobody" could get to it
<maz>
ah, finally a realistic date for the dev kit: "Est. Ship: 9 Jan 2025 -- Est. Delivery: 13 Jan 2025)
<JensGlathe[m]>
so they're re-designing and manufacturing them
<maz>
most probably. I hope they keep the serial debug port on the new board though.
<macc24>
a lot of x elite laptops have them... why would they remove it from the dev kit
chrisl has joined #aarch64-laptops
<maz>
why would QC do something stupid? is that a rhetorical question?
<macc24>
they can't be that dumb, can they?
<Jasper[m]>
macc24: Considering the way X Elite launched
<maz>
having dealt with QC for a couple of decades, I have a precise idea of what low they can sink.
<JensGlathe[m]>
my remaining order has this estimate now, too
<JensGlathe[m]>
This is so odd... They had only a prototype and shipped that one to @geerlingguy?
<maz>
lies, damn lies, and marketing.
chrisl has quit [Ping timeout: 480 seconds]
<JensGlathe[m]>
Dangerously close to the truth, then
SpieringsAE has joined #aarch64-laptops
<SpieringsAE>
there is at least one more person with the devkit, I believe it is sibis in this irc
<SpieringsAE>
ah yeah they also seem to be upstreaming a basic dts for it
<SpieringsAE>
ah okay that seems to be a qualcomm employee
<JensGlathe[m]>
so they got 2
<maz>
macc24: do you have any detail on which laptop has a uart more or less exposed?
<macc24>
maz: my yoga slim 7x has a uart that you can access after removing bottom plate and ssd
<macc24>
other laptops seem to have debug uart ports defined in their dts files
<macc24>
macc24: it can be easily soldered to, and there is enough space between the port and ssd to fit a small cable, which you can then route outside the chassis through ventilation holes
<maz>
macc24: might be an option then.

qcom seems to use devicetree files in their uefi on x1e80100
<Jasper[m]>
How so?
<JensGlathe[m]>
c'mon
<JensGlathe[m]>
the hexagons get fdts in the .elf files, yes
flokli has joined #aarch64-laptops
<macc24>
Jasper[m]: binwalk-ed a uefi update and found a bunch of dtb files
<macc24>
huh there are devicetrees for hamoa and purwa with and without ddr
<macc24>
JensGlathe[m]: it would be so funny if they were making a dsdt out of an fdt
<JensGlathe[m]>
yes, def

what says the #2 one, looking big enough to be a complete description

chrisl has joined #aarch64-laptops
<JensGlathe[m]>
no its not, but still interesting 😁
chrisl has quit [Ping timeout: 480 seconds]
<JensGlathe[m]>
descriptions for ufs, i2c, pil, lots of sensors
<robclark>
I could believe that dtb is useful for uefi
<robclark>
macc24: did you get a uefi update for 7x?
<macc24>
robclark: get - yes, have installed - no

macc24: are uefi updates finally on lenovo's site? I seem to have an earlier version than everyone else, and am expecting that an update will fix the non-working kb in grub/shell.efi/sd-boot/etc
<robclark>
I won't have a chance to install it until I'm back from XDC this weekend, but lmk how it goes if you install it
<macc24>
they are distributed via windows update
<robclark>
ahh, that is what I was afraid of (nuke'd windows a long time ago)
<macc24>
i also have old version, and keyboard works somewhat fine in systemd-boot
