ChanServ changed the topic of #lima to: Development channel for open source lima driver for ARM Mali4** GPUs - Kernel has landed in mainline, userspace driver is part of mesa - Logs at https://people.freedesktop.org/~cbrill/dri-log/index.php?channel=lima and https://freenode.irclog.whitequark.org/lima - Contact ARM for binary driver support!

<linkmauve> Hi, do you have a TODO list or a set of issues that would happen on the PinePhone?
<linkmauve> I don’t have it yet, but I’ve already ordered it.
<linkmauve> Also, I know this isn’t related to Lima, but is the display controller fully working right now? Will I get all planes supported in DRM and such?

<enunes> linkmauve: you can search for reported lima issues at https://gitlab.freedesktop.org/mesa/mesa/-/issues?label_name%5B%5D=lima
<enunes> there is no specific case for the pinephone
<enunes> if you hit some rendering issue please report it to the mesa issues, but please dont if it's only display controller related
<linkmauve> Sure. :)
<linkmauve> I don’t have it yet, I was just wondering what needed contributions.

<linkmauve> What do you use for performance work for Lima? Do you have performance counter? Can you see how much work is done in vertex shader vs. fragment shader vs. fixed function vs. data transfers?
<linkmauve> Do you have some architecture document about the GPU?

<enunes> linkmauve: we dont have much performance data, nobody ever focused too much on it. I have working patches for performance counters in a pending MR, but that work is stalled, you can apply the patches and try it if you want
<linkmauve> I could try that on my Olimex Lime, but I’ve heard the performance characteristics will be completely different with a better memory bus and CPU and a newer revision of the Mali.
<linkmauve> enunes, can I use the shader compiler offline (on an x86 computer), so that I can see what could be optimised?
<enunes> as for documentation, all we have are the old lima project website referenced in the readme and for the instruction sets https://gitlab.freedesktop.org/panfrost/mali-isa-docs
<enunes> sure, you could try comparing results with the offline shader compiler
<enunes> if the bottleneck for your application is gpu execution time, that is
<linkmauve> I have no idea which applications I’ll be using on this phone even. ^^
<linkmauve> But I have a game engine I wrote a few years ago I’ll want to run, at least.
<linkmauve> I wrote a GLES 2.0 renderer for it back then, then never played it on a mobile device.
