00:56 <zdykstra> How's the Surface 7 right now? Useable with a few things missing, or completely unstable?

08:24 <konradybcio> if you don't need input devices other than the keyboard..

08:58 <SpieringsAE> yeah I would say usable with a bit more than a few things missing most likely.

10:47 <konradybcio> krzk x1e hifi.conf hardcodes four-speakers and wsa2 usage and channels=4.. is there a clean way to abstract that?

10:58 <krzk> konradybcio: sorry, no clue, I don't knowmuch about UCM files

17:05 <ruen> Ho,

17:10 <ruen> Hi, I installed the Ubuntu image from that one Google Drive folder on my Lenovo Slim 7x and it's really really cool even with the issues it has.

17:10 <ruen> I'm just wondering if there's a way to profile or find out why some games don't work very well? Like I tried Sonic Adventure 2 and that game seems to be super slow regardless of resolution and system monitor shows the CPU being used a whole bunch and then a Hat in Time runs pretty well at low 1080p settings but it stutters every 4 seconds or so regardless of quality also

17:17 <JensGlathe[m]> The image is a bring up aid... there is quite some work (imo) to do afterwards. Didn't come around to document the more important steps.... (full message at <https://matrix.org/oftc/media/v1/media/download/AYxiAwpJG53Ic9MJ9PY2raeu8nvXfYIhVC-BUdSSgQ7wMw4l0dzLrkr-Cz-6h26FEyJptsP4Jg4STPDsr49eYXJCeSg3QR5QAG1hdHJpeC5vcmcvUXZGdmZQRGxaTmhmTnZna2tsZ3hMc3F1>)

17:19 <JensGlathe[m]> This should give you GPU acceleration among other things.

17:22 <JensGlathe[m]> and yes, there's a new kernel available on GD too, but don't know of the state of the dtb

17:29 <ruen> Oh neat, I only imported the GPU firmware .

17:29 <ruen> But thank you I'll try doing the other things you listed

18:59 <macc24> i didn't know lenovo was into making custom chips

19:01 <tobhe_> macc24: do you know what it does?

19:02 <macc24> i have no clue

19:02 <macc24> found it on otherwise quite empty backside of slim 7x's motherboard

19:02 <macc24> that chip in the other corner is it8987vg

19:29 <kuruczgy[m]> macc24: did you manage to locate the hall sensor? Any clues around it? (E.g. visible traces connecting it to something interesting)

19:32 <ruen> I think the chip is for Lenovo's AI battery boosting thing. They advertise it on other models, but I thought it was handled by the NPU this time

19:48 <macc24> kuruczgy: well there are some chips whose markings are really hard to read

19:50 <JensGlathe[m]> polarized glasses

19:50 <macc24> i meant more as in "small" than "reflecty"

20:19 <steveej[m]> jhovold: i resolved the boot problems by enabling the following kernel options:... (full message at <https://matrix.org/oftc/media/v1/media/download/AWyiNzkTj1fXHw6vRCTuIpMQAc0P8xqXRt55_j0sxWd-KOr-WXnKXjy1z2q3KNmLlGjLYiLbZYrZ7yIDOVC3s0ZCeShBpcBAAG1hdHJpeC5vcmcvTXdFVEplSWpyblZEV2FOSGFCanVoT3l6>)

20:20 <steveej[m]> as a reminder and for others' info, this is when switching from 6.11.0 -> 6.12-rc2) seems to be a change in defaults for the 6.12 series. maybe you can enable these in your defconfig

20:21 <macc24> it was fine for me, not sure why would the kernel install compressed modules if the option wasn't enabld

20:22 <steveej[m]> no idea. on nixos i ended up with uncompressed kernel modules and initrd couldn't load them for whatever reason

20:22 <kuruczgy[m]> Yes, NixOS expects to use compressed kernel modules

20:25 <steev> seems kinda broken if not compressing kernels breaks booting

20:28 <kuruczgy[m]> Well the issue was that NixOS enables MODULE_COMPRESS_XZ, so it rightfully expexted modules to be compressed. This changed with 6.12-rc1, as now MODULE_COMPRESS_ALL is also needed.

20:29 <macc24> okay so i didn't find any pads with i2c

20:29 <macc24> s/i2c/i2c6/

20:29 <macc24> s/i2c/i2c6 :(/

20:47 <JosDehaes[m]> OMG, got UCM working on yoga slim 7x!

20:48 <macc24> are all speakers working?

20:49 <JosDehaes[m]> not yet, it does in the test script, but the UCM file only enables left channel for now, trying to figure out

20:50 <JosDehaes[m]> but I WAS able to get GNOME to see the card, and plays audio in youtube

20:55 <JosDehaes[m]> something must be very off, as the front channels are coming out of the left side and the rear out of the right 😅

20:56 <JosDehaes[m]> not sure where the problem is, in TPLG or UCM 🤔

21:10 <macc24> i'd guess tplg

21:31 <JosDehaes[m]> and after a reboot, can't get it to work anymore 😅

21:54 <macc24> okay the ec in slim7x is a derivative of 8051

21:55 <macc24> and ghidra can decompile its firmware just fine

22:31 <kuruczgy[m]> The it8987vg that you mentioned is the EC, right? (A google search turns it up as an EC in various laptops, but I could not find a datasheet so far.)
