Exynos 990 will probably be the first SoC shipping it
<endrift>
Are there any easy-to-get dev boards with bifrost? Maybe I could start work on a driver if I got it (I'm being idealistic, I've not even unpacked my Pine H64)
<HdkR>
Hardkernel's ODROID-N2
<HdkR>
Also the ODROID-Go Advance will have Bifrost
<endrift>
oh shit I want to get the ODROID-GO Advance already
<HdkR>
I know, I'm going to get one as well
<endrift>
too bad it sold out before I realized it was for sale
<HdkR>
It's not even for sale yet :P
<HdkR>
Quirk of their storefront software I think
<endrift>
oh
<endrift>
I was just saying what someone said to me
<HdkR>
:P
<HdkR>
Also Panfrost has my beginning Bifrost compiler code. You could technically work on it without a Bifrost board atm
<chrisf>
hikey960/970 are easy to get and have bifrost gpus
<endrift>
Compilers are foreign to me
<HdkR>
Oh right, I have one of those as well
<HdkR>
Or..both?
<endrift>
hmm those look a little pricier
<HdkR>
Yea, that's why the N2 is nice since it is cheaper
<HdkR>
N2 also has Linux Mali blobs that you can poke at
<endrift>
I'm not sure if I'll use it for anything though so I'm disinclined to buy one tbh
<HdkR>
even if it is fbdev only
<HdkR>
endrift: If I get a Go Advance before they run out of stock then I'll frisbee one at you :P
<endrift>
thanks :D
<endrift>
I'm gonna try to get one too
<endrift>
I got a Pocket Go and that was a huge mistake
<endrift>
and by huge I mean I should just throw it out but it wasn't that much money
<HdkR>
It's an ESP32 so it is less fun to play with
<endrift>
the screen buzzes
<endrift>
it's awful

frowns at rockchip's gpu configuration in the 3326 (go advance)
<HdkR>
Why in particular? Because it is super tiny? :P
<chrisf>
g31 mp2
<chrisf>
yes
<HdkR>
I can forgive it because it is also tied to the tiniest 64bit ARMv8 CPU cores
<HdkR>
endrift: One of the biggest blockers for the bifrost shader compiler is an instruction packer+emitter. Which could be done entirely outside of a bifrost board :)
<HdkR>
and can be tested with the disassembler
<endrift>
ah
<HdkR>
One of those things that I don't care for doing :P

HdkR: Word of advice -- make sure you keep control flow in mind when you do the v1 of the compiler
<alyssa>
Or otherwise you'll just end up rewriting :(
<anarsoul|c>
You'll end up rewriting even if you keep CF in mind if it's your first compiler
<alyssa>
anarsoul|c: That's also unfortunately ture.

tomeu: I have a patch for sRGB blend shaders using the common NIR lowering (rather than the native ops)
<alyssa>
I'd of course rather use native ops but until they're well understood, I just want to get things working first, and this gets blend.fbo_srgb.* passing :)

Passed: 1152/1152 (100.0%)

So I tried out Terraria on my PineBook Pro with panfrost but the graphics look like this: https://i.imgur.com/srOJHNh.png
<nhp>
Is there any kind of logs/debug info I could give to help figure out what's going on here?

Ruh roh... just upgraded Panfrost (to latest master from a few week old master) and performance has regressed pretty terribly
<alyssa>
(for glamor)
<alyssa>
Huge amount of time spent doing software tiling, but even if I disable tiling, performance is still worse than it has been
<alyssa>
A lot of time spent allocating polygon list for instance.
<alyssa>
(Maybe BO cache garbage collection is too aggressive?)
<alyssa>
nhp: Send an apitrace, uh
<alyssa>
$ apitrace trace [app]
<alyssa>
That'll give a .trace file which you can upload somewhere and send to me (here or email to <alyssa@collabora.com>)

nhp: I didn't realize terraria had arm64 linux builds?
<nhp>
It doesn't, but all the libraries it needs can be built for aarch64, so if you do that you can get it running
<hanetzer>
oh, izzit java?
<hanetzer>
same peeps as minecraft right?
<nhp>
It's C#, different people
<nhp>
It uses FNA for the Linux version
