21:12 <anthony25> steev: on jhovold's 6.16-rc7?

21:13 <anthony25> robclark: yes, I'm going to try on a clean branch, it might conflict with another patch

21:17 chrisl has quit [Ping timeout: 480 seconds]

21:24 <steev> anthony25: si - a few other patches on top - https://github.com/steev/linux/commits/thinkpad-t14s-oled-6.16-rc7/ specifically

21:25 chrisl has joined #aarch64-laptops

21:37 chrisl has quit [Ping timeout: 480 seconds]

21:45 chrisl has joined #aarch64-laptops

21:53 chrisl has quit [Ping timeout: 480 seconds]

21:56 <anthony25> it indeed conflicted with another patch

21:58 <steev> i don't recall any conflicts

21:59 <anthony25> I'm applying multiple patches touching msm, I had a conflict on one commit, so either I applied it badly or it didn't work well together

22:01 <steev> what is the other patchset?

22:01 <anthony25> I'm not gonna try to narrow down which one it is, the series make animations super laggy on hyprland (I guess that the frequency is a bit too slow to ramp up), I'm going to answer on the list

22:02 chrisl has joined #aarch64-laptops

22:02 <steev> ah, i'm in gnome on wayland (i assume that ubuntu is wayland with their gnome stuff anyway))

22:03 <anthony25> the 2 other patchesets I'm using are speedbin support and GMU bandwidth

22:07 <steev> i think i have the gmu bandwidth, but not speedbin

22:08 <akhilpo> Are you sure the GMU BW patch is not the culprit?

22:09 <akhilpo> It would be helpful if you can confirm that.

22:10 <akhilpo> Also, I am planning to drop this patch from the IFPC series: https://patchwork.freedesktop.org/patch/664830/

22:11 <anthony25> akhilpo: let me try

22:13 <anthony25> patchwork is super slow on my side to load, I'll try to drop this patch once it finishes loading

22:14 <anthony25> ok got it

22:15 <akhilpo> Another potential culprit is this one: https://patchwork.freedesktop.org/patch/664845/

22:15 <akhilpo> But it would be helpful if you can confirm which patch exactly is the real culprit.

22:16 <akhilpo> I see that your device (yoga 7x) has higher resolution (3K) than my test device.

22:17 <akhilpo> Also, I am not sure if hyperland is more GPU heavy than Gnome.

22:18 <anthony25> I can test on Gnome as well

22:18 <akhilpo> Yes, please. Thanks in advance.

22:18 chrisl has quit [Ping timeout: 480 seconds]

22:18 <anthony25> Gnome falls back to triple buffering, so it could hide the issue

22:19 mjeanson has quit [Remote host closed the connection]

22:19 <anthony25> but even hyprland with the beta-scheduler that does a similar thing has laggy animations

22:20 <akhilpo> Is it janky throughout the animation? or just an initial jank?

22:20 <anthony25> it's like 10fps animation

22:20 <akhilpo> Could you also check if there are any errors in the dmesg?

22:20 lynxy has quit [Read error: Connection reset by peer]

22:21 <anthony25> if I switch back and forth between workspaces, it's smooth after 1 second or so

22:28 <akhilpo> Any pointers on installing hyperland on debian?

22:29 <akhilpo> I have debian Trixie installed on my device.

22:30 <anthony25> on debian it's quite annoying to install it, it requires really recent libinput and wayland-protocols

22:30 <anthony25> I'm gonna test on gnome instead, I have a basic default config

22:30 <anthony25> if I have the same problem it'll be easier for you to test

22:31 <anthony25> (I'm compiling with the GMU BW patch)

22:32 <anthony25> I use fractional scaling, so it might add more load on the GPU

22:32 <akhilpo> you mean without GMU patch?

22:32 <akhilpo> >the 2 other patchesets I'm using are speedbin support and GMU bandwidth

22:32 <akhilpo> You mentioned earlier that GMU patch was already there.

22:33 <anthony25> I mean with, I was saying that applying your patch over the patches I had applied resulted in a black screen (and freeze) at boot

22:33 <anthony25> and I have 2 patches that touch at msm: GMU patch and speedbin

22:34 <anthony25> *2 patches series

22:34 <akhilpo> I don't think that GMU bw patch would give any significant perf benefit. It mostly about routing the bw vote via gmu.

22:34 chrisl has quit [Ping timeout: 480 seconds]

22:35 <anthony25> ha I thought you wanted to know with which other patch it might conflict, that's why

22:35 <akhilpo> Btw, no errors in dmesg, right?

22:36 <anthony25> I haven't checked, I deleted the kernel built with ifpc, I'm rebuilding it and I get back to you

22:42 chrisl has joined #aarch64-laptops

22:50 chrisl has quit [Ping timeout: 480 seconds]

22:51 <anthony25> with the GMU bw patch, it works, maybe I badly resolved the conflict with my backport of the Speedbin patch series

22:52 <anthony25> nothing in dmesg

23:01 <akhilpo> You mean the animation lag is resolved now (on hyperland).

23:02 <anthony25> no, I mean I don't have the black screen at boot

23:02 <anthony25> the animation lag is not resolved, I'm testing right now under gnome

23:02 <akhilpo> Ah! we were still at black screen :D

23:03 <akhilpo> All along I was talking about the animation lag issue. So the patches I mentioned are related to the animation lag issue.

23:04 <anthony25> sorry, misscommunications :p

23:05 <akhilpo> It would be helpful if you can narrow down the patch which is causing the lag. Should be one of those I mentioned above.

23:05 <anthony25> sure, I'll go through them
