<rasterman> daniels: twitter? it's a public world wide irc channel for those with short attention spans... as obviously anything > 140chars is TL;DR :)
<daniels> rasterman: I don't think either of us can judge others for length of attention span tbf :P
<rasterman> daniels: :P :)

<cphealy> In the past I worked with an old Adreno A200 and with this GPU, there was a performance benefit to using glInvalidate as it saved us performance by allowing us to skip the cost of glClear (which was done using fragment shader). Is there any benefit to doing glInvalidate in the same manner on Mali GPU or is clearing essentially free?
<macc24> cphealy: check if `perf` debug option complains if you do glClear

<alyssa> clear is essentially free
<alyssa> I am suuuper tempted to play with Midgard, just for fun
<alyssa> done with Bifrost/Valhall for the week, don't have energy to do M1 stuff, and idk
<alyssa> Midgard is so cute I just wanna squish it
<macc24> alyssa: what if u make panvk work on midgard

<robclark> cphealy: the benefit of glInvalidate() is more about avoiding re-loading the tile buffer if there is no clear
<cphealy> Based on what alyssa and robclark said, it sounds like glInvalidate will not help like it did with the old A200. This is because clear is free, I don't need to find a way to avoid the cost of clear.
<cphealy> tnx alyssa and robclark
<alyssa> i wonder what a midgard compiler in Rust would look like wait no bad alyssa
<anarsoul> cphealy: if I'm not mistaken glInvalidateFramebuffer() will help in case if you don't need preserve depth buffer contents
<anarsoul> of course, if it's wired in panfrost :)
<anarsoul> *wired up
<alyssa> it should be
<anarsoul> is there glInvalidateFramebuffer equivalent for ES2?
