09:02 <warpme_> hi *

09:10 <warpme_> I just got current mesa master working on s912 t820 with mainline 5.2.1 and give it try with mythtv on my distro (minimyth2). I see gui, can browse it but playback attempt gives series of oom. dmesg is like this: https://pastebin.com/CeBKb5vR If this is because wip - then pls forget this report. If not - pls sugest how I can help with resolving panfrost oom issue…

09:28 <guillaume_g> alyssa, rtp: I tested your suggestion to switch to DRM_FORMAT_MOD_LINEAR and kmscube shows a nice colorful cube! :)

09:31 <guillaume_g> Apparently, it breaks on Rockechip with LINEAR mode. Any idea how we could make both rockchip and exynos happy?

09:40 <rtp> guillaume_g: oh, nice. last time I tried panfrost on my exynos with t628 (months ago) I only got black screen.

09:43 <guillaume_g> rtp: it is a t604 with exynos 5250. I needed to hack the Device Tree, use kernel 5.2.0 and Mesa 19.1.2 with my hack about DRM_FORMAT_MOD_LINEAR

09:49 <rtp> is it on the snow laptop ?

10:02 <guillaume_g> rtp: yes, it is

10:18 <guillaume_g> Should I report my problem with DRM_FORMAT_MOD_LINEAR on gitlab, or somewhere else?

10:25 <rtp> no idea :(

10:27 <bbrezillon> guillaume_g: I know alyssa prefers emails

11:37 <rtp> guillaume_g: btw, can you put your mods online somewhere please ?

11:50 <guillaume_g> bbrezillon: ok. Is there a mailing list dedicated to panfrost?

11:51 <guillaume_g> rtp: my Mesa hack: https://build.opensuse.org/package/rdiff/home:Guillaume_G:branches:X11:XOrg/Mesa-drivers?opackage=Mesa&oproject=home%3AGuillaume_G%3Abranches%3AX11%3AXOrg&rev=4

12:09 <rtp> guillaume_g: thanks. that's the only thing you had to change ? nothing on uboot/kernel/dtb/... side ?

12:10 <bbrezillon> guillaume_g: nope, just send it to mesa-dev and Cc tomeu and alyssa

12:12 <guillaume_g> rtp: I added mali node to DTB: https://pastebin.com/2944Y1Sm

12:13 <guillaume_g> rtp: and that's the only 2 things I needed to change from upstream

12:22 <rtp> guillaume_g: great, thanks

12:22 <guillaume_g> bbrezillon: could you send me e-mail addresses in pm, please?

14:12 <alyssa> warpme_: :/ I'm not sure what to suggest -- memory usage has been a pain point for a little while now.

14:12 <alyssa> if it makes your feel better solving that is on my short list of TODOs for the next few weeks? :)

14:13 <alyssa> guillaume_g: Wow, nice!

14:13 <alyssa> You're officially the first person to get Panfrost working on T600, so there's got to be some bragging rights there ;)

14:13 <alyssa> guillaume_g: alyssa.rosenzweig@collabora.com and tomeu.vizoso@collabora.com, fwiw

14:17 <alyssa> guillaume_g: Re display system weirdness, I don't know what the right approach is

14:17 <alyssa> (Tomeu will know)

14:18 <alyssa> guillaume_g: " mesa-19.1.2" ..Don't do that

14:19 <alyssa> 19.1 isn't ready for, well, much of anything; 19.2 (in a few weeks) I'm hoping to be ready for people :)

14:19 <alyssa> mesa master will be much more stable than 19.1

14:20 <guillaume_g> alyssa: ok, good to know. I used what is in my distro atm ;)

14:20 <alyssa> guillaume_g: Don't worry, I'm a Debian user, I get it ;)

14:21 <guillaume_g> alyssa: I am an openSUSE Tumbleweed user. ;)

14:22 <alyssa> Which one is Tumbleweed? That's the stable-rolling one, right?

14:22 <guillaume_g> alyssa: that's right :)

14:22 <alyssa> So jealous, tut tut :p

14:22 <guillaume_g> :D

14:24 <alyssa> Okay, my agenda is clean, what now

14:24 <alyssa> I guess more memory management stuff

14:28 <alyssa> guillaume_g: Hey, are you up for testing a branch for me?

14:39 <alyssa> If you are, look into gitlab.fd.o/tomeu/mesa branch always-64-v2

14:40 <alyssa> You'll need to disable the whitelisting in pan_screen.c, though

14:41 <alyssa> gitlab.fd.o/alyssa/mesa branch always-64-v2 should be ready to try (plus your LINEAR patch)

15:22 <guillaume_g> alyssa: I could test something, but probably not this week.

15:40 <alyssa> No worires
