01:52 <derzahl> without the msm driver isnt there a default graphics driver that works for just displaying text?

01:58 <derzahl> its gotta be able to use whatever driver grub uses right?

02:00 <derzahl> how can i just make it stay in that video mode while the initrd is loading

02:07 <HdkR> If you're booting from efi then `video=efifb`

02:08 <steev> the problem is he's reaching msm takeover, and it's not coming back

02:08 <HdkR> ah

02:09 <steev> i wonder if something like video=efifb blacklist=msm would work

02:10 <steev> at least to debug, no idea if it would really really work

02:11 <steev> bamse: when you were sitting outside playing with the audio... did you happen to keep notes?

02:18 <derzahl> i tried console=efifb

02:18 <derzahl> let me try video=efifb

02:19 <derzahl> ive tried not including msm in the initrd, so blacklist shouldnt be needed

02:24 <derzahl> no difference

02:25 <derzahl> is efifb what I want?

02:25 <derzahl> i was thinking that was the problem

02:25 <steev> bamse: also, looking closer in the ucm2 files, it doesn't appear we enable the mic on the c630, it does the headset mic only

02:25 <steev> srinik: ^^

02:25 <derzahl> isnt there a vesafb or something more basic

02:25 <steev> derzahl: efifb is the most basic you have on these, since it's literally using what the system booted with

02:38 <derzahl> ah

02:48 <derzahl> doesnt seem like grub is using efifb though. it doesnt load any module for it

02:48 <derzahl> its right after the "efi" lines are printed on the screen that my screen goes blank usually

02:53 <steev> well, msm takes over about 2 seconds in

02:54 <steev> [ 2.646500] fb0: switching to msm from EFI VGA

03:03 <steev> is it not booting at all? can you ssh in after you blindly unlock it?

03:03 <steev> look at logs?

05:04 <derzahl> it works fine on the version of 5.15 that i can blindly unlock. 5.11.22 however doesnt seem to boot at all. Im just looking to get some consistancy

05:05 <derzahl> whether is using splash and KMS or using straight console until X starts

05:07 <derzahl> so im trying now to blacklist msm completely

05:08 <derzahl> then ill try the opposite, disable efifb and using msm as early as possibe

05:12 <derzahl> i wish i could catch the lines it prints before going blank

05:12 <derzahl> wonder if this can do video over usbc

05:31 <derzahl> ok, got the lines to pause. "EFI stub: exiting boot services" is always the last line i see

05:48 <derzahl> oh, maybe ill just try virtualizing an ancient x86 framebuffer driver

05:48 <derzahl> https://wiki.archlinux.org/title/uvesafb

08:08 <derzahl> so as someone whose semi recent laptop experience has been on&off dicking with this c630, but likes low power and portable laptops alot...should I choose a macbook pro m1 or a lenovo x1 carbon, for my new work laptop?

08:08 <derzahl> i think asahi is pretty much together on the m1 right? too bad a mb air isnt an option for me

08:08 <derzahl> no idea what the x1 carbon is

08:14 <derzahl> my reason for getting this c630 initially was the mac m1. i bought a m1 mbair right when it came out without reading anything about it. was 1) unhappy that it still had no magsafe. and 2) really sad that linux on the m1 seemed years off and 3) sick of how OSX had been getting worse and worse over the years

08:15 <derzahl> so i sent it back and then bought this craptop

08:15 <derzahl> which is actually pretty impressive for what it is

08:16 <derzahl> kinks and all

08:18 <derzahl> but since apple will never stop until osx IS iOS I refuse to put up with their OS anymore

10:36 <steev> i'd suggest the x1c

10:37 <steev> there's still a lot of out of kernel stuff and nothing like cpufreq with the m1

10:38 <HdkR> I'd also recommend x1c as well and I love AArch64

16:05 <gwolf> I also tend to side towards the X1... I recommend everybody to stay as far from Apple products as possible :-]

16:06 <gwolf> But yes, the use cases for a C630 and for a X1 are quite different. The C630 is not meant to be a powerhorse.

16:44 <bamse> steev: what notes are you looking for?

16:45 <bamse> steev: and yes, we only have line-in, not the microphones...i remember srinik lookig at that, but there was just noise...perhaps the referenc voltage was wrong or something, or it was the wrong mics? hard to say without schematics

16:50 <gwolf> bamse: Oh, is the line-in supposed to work in C630? :-)

16:51 <gwolf> Had I known earlier... When I went on vacation, I bought an external USB sound card to be able to have a microphone

16:51 <gwolf> (it worked great, of course)

16:51 <bamse> gwolf: yeah, it's supposed to work...

16:51 <gwolf> bamse: Good to know ;-)

16:52 <bamse> gwolf: but i bet whomever you chatted with appreciated the better sound quality? ;)

16:52 <gwolf> BTW... Have there been any advances on getting the displayport-over-USB-C discovered?

16:52 <bamse> yes

16:52 <gwolf> bamse: Well, it was my students (I took some exams from Argentina...)

16:52 <bamse> cool

16:53 <gwolf> bamse: yay! I will put "rebuilding a newer kernel" as one of my priorities.

16:53 <bamse> gwolf: there's advances, not patches yet...

16:54 <bamse> gwolf: well, there's patches on the list for the integration in the dp-driver, and i found that we have the phy patches ready to be send out...and i did some more research on the EC protocol

16:56 <gwolf> OK, I see

16:56 <gwolf> Well, I'll be patient and wait... Or if there is anything a non-kernel-hacker can help you do, please tell me!

16:56 <bamse> gwolf: so it's unfortunately fairly close to the same status as last time you asked, in practice

16:57 <gwolf> OK. Well, I'll take my old laptop with me to classes (two weeks from now)

16:57 <bamse> of maybe you asked long enough back that we have an overall agreement on the dp-driver side at least :)

16:57 <bamse> you would use the c630 in your classes if you had working dp?

16:58 <gwolf> Yup

16:59 <bamse> cool

16:59 <gwolf> My old Thinkpad X230 is too brittle... The battery falls out, the case is cracking at several parts

16:59 <gwolf> And I am just perfectly happy with the C630 as a general-use laptop

16:59 <bamse> my kernel tree for c630 is down to 2 patches, one adding the battery driver and one enabling the battery driver

17:00 <bamse> so figuring this piece out would allow me to attempt upstream that, and perhaps be able to just run the Torvalds' kernel straight off

17:00 <bamse> i know that steev has a bunch of other fixes, but we're quite close now at least

17:01 <gwolf> right

17:01 <gwolf> I'm currently running steev's 5.14 -- I haven't updated as last I checked it was the latest non-RC kernel he had tags for

17:14 <derzahl> thanks for the input. is the build of the x1c pretty high end? Ive never seen one. But I do have a x280 and a T460 or something laying around so if its not much different id rather just have the m1 and play with asahi

17:14 <derzahl> apple build quality is top notch and I still use my 2016 mbair as my personal daily driver because i havent found anything better

17:24 <macc24> gwolf: elitebook 2570p has socketed cpu and is same size as x230 ;)

17:25 <bamse> every time i feel its time to change cpu they have changed the socket...

17:26 <gwolf> mmac24: I loved the X230, but it's a bit large+heavy for my taste.

17:29 <macc24> bamse: sucks that intel stopped socketing laptop chips after haswell...

17:29 <bamse> macc24: but when do you need that?

17:30 <macc24> bamse: when i want to change cpu in my laptop for a better one? the machine i'm typing from was upgraded from i5 2540m to i7 3610qm

17:31 <bamse> macc24: unfortunately i'm not familiar with the numbering, is that much faster?

17:32 <macc24> bamse: yea, over 2 times faster in multi threaded workloads

17:34 <bamse> okay, that's pretty nice

17:34 <gwolf> heh... I remember the "Pentium Overdrive" chip I had, that worked in motherboards with a 486 socket

17:35 <macc24> the only way i can keep it under 105 deg is liquid metal and holes in bottom of chassis xDD

17:35 <macc24> in a 12 inch form factor

17:35 <gwolf> It looked really... as something bad done. There was a full line of pins just hanging outside the socket!

17:35 <gwolf> Still, it... worked very well to speed up my 486 ;-)

19:05 <steev> bamse: if you recall what the actual volume entries were out of the thousands of entries in alsamixer, because with the new ucm2 files, a) it's far too quiet and b) the right speaker is much lower volume than the left

19:07 <steev> gwolf: i have 5.15, 5.16 and 5.17 rcs... but a lot of the patches on top of 5.15 and 5.16 are/were testing patches that have ended up in the newer versions (of course)

19:07 <gwolf> of course

19:08 <gwolf> let me check... I pulled from your tree a couple of days ago, and I got...

19:09 <gwolf> The tags for c630-5.* are all on rc

19:09 <gwolf> Oh - but you do have linux-5.1

19:09 <gwolf> Oh - but you do have linux-5.1[456].y branches

19:10 <steev> yeah, the linux-5.XX.y are the stable trees with c630-ish patches on top

19:11 <steev> the c630-5.x are typically torvalds tree with c630 patches on top

19:11 <steev> and various points of his RCs

19:12 <steev> i've started playing with b4, instead of pwcli, and it's... kinda nice

19:12 <gwolf> ok -- I'll try newer kernels based on that. But not now, as it's almost time to go pick up the kids...

19:12 <steev> there's also some radxa zero trees, but yeah

19:13 <steev> if you use the webcam, i would suggest staying with 5.15, although i pulled in a couple venus patches onto 5.16 and that seems to have helped somewhat

19:13 <gwolf> regressions are not fun :-( I'd expect things to go always improving as time goes on ;-)

19:14 <steev> it's a little frustrating because i don't at all understand the gstreamer stuff, and how venus fits into the equation

19:15 <steev> also the 5.16.x stable releases have been kinda fast and furious lately

19:15 <steev> i swear we just had .8 a couple days ago, and .9 was already released

19:17 <gwolf> :-| I'd expect changes between them to be quite epsilonic... bugfixes more than anything else

19:19 <steev> i don't test the webcam often, so i never noticed :(

19:23 <gwolf> makes perfect sense :-]

19:25 <steev> and thanks to a picture from ebay we do know what ec chip the boards have :D

19:25 <steev> gwolf: but yeah, we finally discovered the EC chip, thanks to a picture on ebay of the motherboard :D

19:25 <steev> the accelerometer(s) should also be possible to use, but i have no idea how to wire them up or how that's supposed to work

19:25 <steev> oh, finally

19:25 <steev> not sure what happened to my internet connection there

19:29 <gwolf> uff... yes, I've been learning quite a bit from watching the conversations in this channel, on what it really entails to understand the connections between components in a system. Nothing like what I'd seen before!

19:29 <gwolf> Anyway, time for me to disappear from the intarwebs!
