07:44 <cwabbott> well, alyssa's not here... but if there's a shader where flushing undef to 0 helps, that just means there are missing optimizations for undef

07:45 <cwabbott> and if you're doing it before out-of-ssa, that's a bad idea because shaders can legitimately have undef as a phi source for partial definitions where the shader author knows that it's fully defined (but our control-flow analysis doesn't)

07:45 <Danct12> is this panfrost?

07:46 <cwabbott> and flushing to 0 hurts those

07:47 <cwabbott> but if you're doing it after out-of-ssa, optimizations can't be as aggressive so it's not the optimal time anyways

14:29 <MoeIcenowy> anarsoul: did you met mesa master PP MMU fault on X glamor?

14:49 <anarsoul> MoeIcenowy: nope, but I didn't do stress testing

14:50 <anarsoul> sway is broken for me with GP error

14:51 <anarsoul> you can try https://gitlab.freedesktop.org/mesa/mesa/merge_requests/1764 - it fixes layout field position, it may fix pp mmu fault

14:57 <MoeIcenowy> anarsoul: BTW glmark2-es2-drm fails, I don't know why

14:59 <anarsoul> do clean rebuild

14:59 <anarsoul> and which benchmark fails?

15:01 <MoeIcenowy> build

15:01 <MoeIcenowy> it doesn't even start

15:01 <anarsoul> then do clean build

16:29 <wens> and clean ccache... wow

16:37 <anarsoul> wens: there's a missing dependency somewhere in build system

16:37 <anarsoul> it's not related to lima, panfrost folks had the same issue

16:38 <anarsoul> maybe it's not necessary to clean ccache, but it takes more than 30min to build mesa on pine64, so I decided not to take chances
