05:44 <anarsoul> rellla: you can also grep #dri-devel logs from 2019, IIRC I discussed clipping with imirkin back then

05:44 <anarsoul> but this bit definitely had an effect on clipping for me

08:15 <rellla> anarsoul: i tested with dEQP-GLES2.functional.clipping.*

08:17 <rellla> 0x2000 needs to be set for points to be rendered inside the viewport. for lines and triangle tests this bit has no effect. at least in the deqp clipping tests.

08:20 <rellla> we still have dEQP-GLES2.functional.clipping.line.wide_line_clip_viewport_center and dEQP-GLES2.functional.clipping.line.wide_line_clip_viewport_corner which always fail. i suspect this is a hw bug?! they also fail with the blob. but this could be worked-around with extending the viewport...

08:21 <rellla> ^^ or there exist some hidden bit, which i haven't found yet

08:28 <rellla> there are also 4 dEQP-GLES2.functional.clipping.triangle_vertex.clip_two.* tests which fail due to z-clipping. i played with (render->depth_test & 0x3) and/or ctx->viewport.near/far and can get this test pass, but i have no solution yet, that doesn't break other tests...

13:49 <tlwoerner> wow, the performance is better with wayland+weston. under x11 i was getting 109-ish, under wayland/weston i'm getting 200-ish

13:50 <tlwoerner> and i'm thrilled to find that it's quite easy (now) to run gui apps under wayland/weston from an ssh connection (just like it's always been under x11) :-D
