ChanServ changed the topic of #aarch64-laptops to: Linux support for AArch64 Laptops (Chrome OS Trogdor Devices - Asus NovaGo TP370QL - HP Envy x2 - Lenovo Mixx 630 - Lenovo Yoga C630 - Lenovo ThinkPad X13s - and various other snapdragon laptops) - https://oftc.irclog.whitequark.org/aarch64-laptops

konradybcio: I have very little clue how to operate windows, other than downloading updates to get latest fw and disabling bitlocker
<konradybcio>
robclark think it was Danylo who added libwrap support for windows
<robclark>
yeah

<robclark> "for next few days I guess..." <- with this -next branch, ath12k doesn't work?

ah I didn't want to break anything so I didn't dare pull too hard 😅

I'd imagine 2de hands is too (your last name seems Belgian)

JosDehaes[m]: for ath12k on that branch, you need `arm64: dts: qcom: x1e80100-yoga: add wifi calibration variant`
<anarsoul[m]>
Maybe a stupid question, but is there a good reason not to use ACPI on linux on aarch64 laptops with UEFI firmware, just as Windows does? Why does Linux still require a DT?

I feel like we need a faq we can link to for that.. but short version is that you won't get support for anything that requires gdsc/clk/icc (so no cpufreq, gpu, any display other than efifb, venus, probably suspend/resume and a bunch of other things)
<robclark>
I guess at current linux is missing some acpi device id's to have basic boot working, but with acpi you won't get any more than just basic functionality
<travmurav[m]>
because windows has most of the information needed in a PEP driver and not in acpi + since on qualcomm platforms (which are historically "embedded" style designs), almost everything is on non-disroverable bus (compared to extensive usage of i.e. pci glue on x86) so much more stuff needs description. Combine that with the fact that qcom platforms are ////very complicated/// and linux support for them was developed for over the last
<travmurav[m]>
10 years, introducing acpi support into all of that is //a lot// of work
<anarsoul[m]>
robclark: A FAQ would be useful assuming there is no chat history on matrix for new users :)
<robclark>
I guess it might have been covered in some linaro/qcom blog post or conf presentation.. but yeah, I guess it's not something you'd expect a new user to dig up
<travmurav[m]>
but yeah, someone should write that up somewhere as I feel we're going to get this question a lot xD
<anarsoul[m]>
travmurav[m]: *sigh* I kind of hoped qcom fixed this mess with running existing OS on new ARM hardware
<travmurav[m]>
tbh It possibly even makes sense on what they did with windows - they just took the cheaper route where they brought up a rather non-normal (for "PC") platform up
<travmurav[m]>
acpi is just not enough in that case I guess
<travmurav[m]>
especially in how carefully all the things have to dance together
owlman has quit [Quit: Konversation terminated!]
owlman has joined #aarch64-laptops
<travmurav[m]>
(and you really want them to dance together so the soc can i.e. go into the lowest power mode properly)
<robclark>
yeah, pm on these things is complex enough that you don't really _want_ to implement it ACPI.. but maybe it could have been traps to tz or something (still that would have moved a lot of code out of the kernel and into fw which has it's own distinct drawbacks)
<travmurav[m]>
but well, generally my point is, when even the 10 year old qcom platforms had the ability to send commands to the PMIC upon the wfi cpu instruction, fully in hardware.... this is many levels of complexity up compared to those funny forced on fixed regulators you see in normal x86 xD
<robclark>
:-P
<FarchordSteveCossette[m]>
So, what should i do to get started with my new laptop?
<FarchordSteveCossette[m]>
Asus vivobook btw
<travmurav[m]>
and now in linux we already have lots of stuff implemented based on mobile platforms (with DT) that carefully makes sure magic like that can happen, so, since x1 is (afaiu) just the same phone soc with ^V new arm cores, it makes the most sense to re-use years of work
<JosDehaes[m]>
compiling (note to self, don't forget to unblacklist the driver :-D)
<steev>
oh, those two patches :D
<robclark>
yup
<HdkR>
Mesa full build is reasonable on device, 2m7s
<steev>
nice
<kettenis>
robclark: are those patches actually enough?
<JosDehaes[m]>
for me it's not working (double checked twice that I have correct modules, kernel, dtb)
<kettenis>
on the vivobook with the firmware I got from windows the battery info messages have an extra 32 bits so I would expect it to produce a ""invalid payload length for battery information request" error message
<kettenis>
(that is on OpenBSD though)
<sera[m]>
the patch just ignores the extra 32 bits
<kettenis>
ah wait, I was looking at abelvesa's tree
<steev>
JosDehaes[m]: what are you testing?
<steev>
just that os-build... build?
<JosDehaes[m]>
oh testing the battery, but reading back, I think I misunderstood 😅. I thought battery info was working, but I guess just the endless spam of qcom_battmgr was fixed
<HdkR>
Nice, vkoverhead is enough to cause msm faults :)
<steev>
JosDehaes[m]: oh, i don't think those two patches are in torvalds yet
<FarchordSteveCossette[m]>
Man, looks like you guys are clawing away at bugs at breakneck speed!
<JosDehaes[m]>
no I built from Rob's tree
<FarchordSteveCossette[m]>
You guys rock! XD
<steev>
oh

bryanodonoghue: did enabling the camera not make it in to 6.11?
<steev>
that means 0x4189 isn't in the kernel (and you might need rob's patches that add it)
<steev>
at least, i assume they do, i didn't look closely
<HdkR>
ah, the patch adds it I see
<robclark>
btw I updated my x1e80100 branch with v2 of the yoga slim screen patches
<robclark>
the "Unknown panel" warning is mostly harmless.. we probably aren't completely powering off the panel (ie. nothing toggles the enable gpio), but I guess at this point there is still a lot of stuff not getting powered off
<robclark>
konradybcio: nice
<HdkR>
ah cool
<robclark>
konradybcio: re: QSEECOM .. I guess that is a thing we should enable on the other x1e laptops too?
<konradybcio>
robclark yep
<robclark>
konradybcio: btw, I guess this would be a good time to check if lenovo is using same signing key across two laptops:
