tomeu: so, should I push a proper patch for this so we can enable bifrost support ?
<
tomeu>
narmstrong: well, we also need the outer shareability change, right?
<
narmstrong>
tomeu: yes
<
tomeu>
though I guess such a change can go independently
<
tomeu>
narmstrong: didn't you have a cleaner set of patches for that? I may be misremembering
<
narmstrong>
tomeu: yes, but it was wrong, so I need to update it

tomeu: I'm looking if we can add a quirk to disable shareability
<
tomeu>
narmstrong: sounds great!
<
tomeu>
do you have everything you need for that?
<
narmstrong>
not really ! Will try to hack something
<
tomeu>
narmstrong: ok, tell me if I may be able to help with anything
<
narmstrong>
tomeu: thx

dstzd: right, AFBC needs the big VOP
<
alyssa>
but 'theoretically' if the little VOP is used, AFBC just won't be negotiated... something is still broken I guess
<
alyssa>
tomeu: Nit: `0x2968A819` should be an appropriately named constant, e.g. GPU_PWR_UNLOCK_UNSAFE
<
alyssa>
Hoping we don't need similar hacks on other GPUs but if we do .. :p

alyssa: I think I got that patch out of my hands by now :)
<
alyssa>
narmstrong: then
<
tomeu>
in any case, the commit log starts with "WIP: Magic...:
<
alyssa>
tomeu: how aggressive of a skip list do we need then.. :p
<
alyssa>
for gles31
<
tomeu>
alyssa: maybe a big one initially, but may be better to check the crashes and ooms before?
<
tomeu>
s/check/fix
<
alyssa>
tomeu: I mean, probably a lot of crashes are "unreachable(this isn't implemented)" kind of things, no?
<
tomeu>
guess those are better addressed with skips

Hey, I was trying recently to run Blender 2.83 and this error popped up: maximum output vertices (2) exceeds GL_MAX_GEOMETRY_OUTPUT_VERTICES
yann has joined #panfrost
<
Pak0st>
is this hardware limitation or at some point Panfrost could enable 2 vertices?
<
alyssa>
Pak0st: we don't support geometry shaders (yet?)
<
alyssa>
older versions of blender should work IIRC
<
Pak0st>
blender 2.79 does work with es2 (thanks to Alexandr Kuznetsov doing android port around 2012)
<
Pak0st>
as long as you can fight through the occasional issues with boost :)
<
Pak0st>
alyssa thanks for the reply, will keep an eye for geometry shader support
<
alyssa>
Pak0st: GS is quite low priority tbh
<
alyssa>
It's a
*lot* of work, will perform quite terribly on Mali, and aside from Blender I don't know of any actual apps that need it
<
alyssa>
i.e. I expect GLES3.1 to be finished on both T760+ and Bifrost before seriously poking at geometry shaders tbh
<
Pak0st>
just knowing that GS is considered at all makes me happy
<
alyssa>
it (and tessellation) are just... hugely complicated with no real payoff I guess :(
<
narmstrong>
alyssa: while I'm on it, what's your steps to test AFBC ? how do I test with kmscube ?

alyssa: indeed, will need to switch to T820, though it was also done on bifrost !
<

narmstrong: ah, not yet, soon!

is there a known issue in panfrost built from master revision?
<
macc24>
some supertuxkart models are drawn quite weirdly
<
macc24>
with 20.1.7 version issue doesn't happen, even with PAN_MESA_DEBUG=gles3
<
HdkR>
melty characters
<
macc24>
oh and it's on mali t760mp4
<
macc24>
and i've noticed that performance has improved a lot when compared to 20.1.7 :D
