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!

<anarsoul> enunes: now that we have fp16 in mesa we can try to optimize varyings a bit
<anarsoul> currently we always use fp32 for varyings
<anarsoul> but we can use fp16 if varying is mediump
<anarsoul> IIRC for GP type is specified in varying descriptors
<anarsoul> not sure about PP though :)
<enunes> anarsoul: sounds like a good idea, I can take a look at the pp part
<enunes> anarsoul: not sure if you ever played with this, I just spent some time setting it up https://i.imgur.com/ffIM1l9.png
<enunes> I'm hoping to figure out how these performance counters work so we can implement something to read them in sysfs and get some better insight on those optimizations
<anarsoul> no, I haven't played with it
<enunes> quite painful to set up actually
<enunes> yeah it's using that
<anarsoul> enunes: we don't really need it in sysfs, we can expose perf counters in mesa
<enunes> but the mali kmod needs to be built with additional options, if you're lucky to build it at all, and the other kernel module needs it too
<enunes> that 'gator' kmod
<enunes> and then to figure out how this streamline tool works
<enunes> I think midgard and newer is a bit different
<anarsoul> enunes: I don't think we need this tool
<anarsoul> all you need is mapping between event and its code
<anarsoul> then expose perf counters in our drm driver
<enunes> yeah me neither, I just wanted to see what it does, now I see what the code actually does
<anarsoul> and wire it up in lima, once it's done we can use gallium hud
<enunes> one annoying thing is that apparently only a few counters can be enabled simultaneously, which is why the blob exposes only "counter_src0" and "counter_src1"
