22:28 <mntirc> hmmm > Unhandled intrinsic load_per_vertex_input

22:32 <kusma> How are you triggering this?

22:33 <mntirc> kusma: i built the latest mesa git and enabled dualSrcBlend also (from the MR) and tried blender again, it's triggered by going to shader tab

22:34 <mntirc> (Blender 4.5.0, Commit date: 2025-03-15 07:54, Hash 1448b7062551)

22:38 <mntirc> interesting, it even renders a bit of that UI before crashing.

22:42 <mntirc> oh neat, i have an actual backtrace

22:44 <mntirc> ah, i guess it's multi draw indirect which is not yet supported, right

22:44 <mntirc> kusma: http://dump.mntmn.com/20250416-blender-panvk-unhandled-intrinsic.txt

22:45 <kusma> Yeah, we don't support that, doesn't blender check for the feature?

22:54 <mntirc> kusma: it does, but i have the check commented out ;))

22:54 <kusma> Haha, ok

22:55 <mntirc> trying to test how many of the yet unsupported features are critical, it seems that multi draw indirect can't be worked around

23:00 <mntirc> yeah, just returning from multi_draw_indirect makes it proceed further

23:07 <kusma> Great!

23:12 <mntirc> strangely though, so far the draw count is always 1

23:13 <mntirc> so it actually succeeds sometimes, in the regular scene view. when early returning from multi_draw_indirect, the objects in the layout/modeler view disappear (i.e. the cube)

23:14 <mntirc> (just looked at this and saw that there's actually an assert for draw count != 1, but it's not hit https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/31314/diffs?commit_id=1f3b8bb9188e0520dea18c0b20fa7f857a2532a2#7aec2888f0789b2889066744c247c7564f66e2af_1470_1496 )

23:19 <mntirc> the problematic codepath is the eevee shadow caster

23:20 <mntirc> (ShadowModule::set_view())
