alexVinarskis[m]: For the Asus Vivobook S15, I wrote a HID-BPF program for getting the function keys working properly: https://github.com/icecream95/udev-hid-bpf
<icecream95>
I'm interested in whether that works on the Zenbook A14, or if it uses different keycodes
svarbanov has joined #aarch64-laptops
<icecream95>
From pictures of the zenbook, it seems to have a function for F11, which the vivobook doesn't (which I consider that a feature since F11 for fullscreen is useful), so at least that would have a new keycode

It's also possible that the magic numbers required to enable setting other features (set_init_unk_[12] in my .bpf program) are different. (I found them by attaching to AsusOptimization.exe with windbg and setting a breakpoint on ntdll!NtDeviceIoControlFile.)

i'm trying to get audio working on the Surface Pro X (sc8180x) which from teardown photos appears to have a WCD9340 which according to the windows drivers goes over SLIMBus and is pretty well defined in the DSDT
<maxboone>
I have no previous experience working with slimbus devices, and according to the DSDT the codec itself also works over SPI (instead of GPIO on the current sdm845 driver?)
krei-se has joined #aarch64-laptops
<maxboone>
Anyways - I can get the system to boot and configure the SLIM bus, but once I try to add the actual codec to the bus it won't boot
<alexVinarskis[m]>
_oftc_icecream95: interesting, that explains what the HIDRAW device with PID 0x4543 is, as the actual keyboard is on 0x0220. Ill try it today/tmr and report back
<maxboone>
Do y'all know any devices where that I can take inspiration from for DTS configuring this, or is there any userspace tooling for slimbus (or docs) available so I can try to work on getting the codec wired without constant reboots
<maxboone>
tl;dr - can't get the wcd934x driver to work on sc8180x and it appears to use SPI instead of GPIO - is there some reference I can work off as a kernel newb?

Answer on the list with Tested-by: jouremail <journame>
<JensGlathe[m]>
Best case is with a short quote from my text, and a short description how you tested (wich port, adapter, display resolution)

thanks a lot JensGlathe[m]!
<robclark>
JensGlathe[m]: has the patch changed at all recently? I've been using a (possibly older) version of it for a couple months now
<Jasper[m]>
Slight nitpick, but might it be worth it to merge both sc8280xp-microsoft upstream DT's? Both are mostly the same hw (except for some obvious things that make one a tablet and the other a mini pc)
<anthony25>
robclark: it's a trimmed version of the older one, without the audio and bluetooth parts
<robclark>
ok.. I guess I trimmed those parts out of the original patch as well.. I'll have to compare them to verify we ended up in the same place
<alexVinarskis[m]>
Maybe [@_oftc_robclark:matrix.org](https://matrix.to/#/@_oftc_robclark:matrix.org) could confirm the behavior?
<alexVinarskis[m]>
I can drop topology file and retry
<alexVinarskis[m]>
Worth mentioning that USB3 devices work in all cases in all ports in all orientations
<JensGlathe[m]>
I have a dev kit, and dp altmode works on all three type-c ports. I could try all three consecutively, though... brb
<JensGlathe[m]>
huh. all three work with 2k@75 when plugged consecutively
<JensGlathe[m]>
aaand... same definition I guess, but no topology file loaded
<alexVinarskis[m]>
Tried without audioreach topology, no change, same error on whichever is last
<robclark>
fwiw, if I boot with right side connected, the display is detected, but doesn't light up
<alexVinarskis[m]>
And if you boot without anything connected, then plug right side after login?
<robclark>
same

I just checked the devkit dts I use against the slim7x dts in the patch, and there is no difference in the additional definitions for retimers and dp, except for ps8830,boot-on; on the retimers. Not sure if this is actually recognized and used in the driver (I looked a few weeks back, found nothing)
<robclark>
it could just be unhappy about the displays I have.. one usb-c and one dp.. don't have an hdmi display handy to test.. (but would be curious what sort of display(s) have been seen to work on the right side, ie. hdmi vs dp

alexVinarskis[m]: matrix features don't render well on irc (e.g. when you're referrng to someone in your replies)
<alexVinarskis[m]>
Ah didn't realize, sorry. Will tag instead, thanks.

alsa-ucm-conf-1.2.14 released this week with configs for t14s and yoga
<jhovold>
and topology files in the linux-firmware april release
<robclark>
nice
<jhovold>
looks like you got x14s and thinkbook 16 in the ucm release as well, JensGlathe[m]
<jhovold>
are there any public topology files for those yet?
<JensGlathe[m]>
and the ThinkBook 16 dts is not even upstreamed yet
srinik has quit [Remote host closed the connection]
<jhovold>
and alexVinarskis[m] got zenbook a14 in there too
<JensGlathe[m]>
yes, both are in audioreach-topology, too
<travmurav[m]>
fwiw on the vivobook s15 I made photos of the subboard only has usb3 A ports and so relevant redrivers, the actual DP/type-c and hdmi is on the mainboard
