16:46 <mntirc> daniels: perhaps interesting for you, one of our users figured out why firefox is slow on panfrost/rk3588 https://community.mnt.re/t/poor-browser-performance/2042/30

16:47 <mntirc> step 1 > Since the panfrost gallium driver disables blit texture transfer, the format conversion falls to software implementation, which is very slow

16:48 <mntirc> > The cause was the _mesa_choose_texture_format(..., internalFormat=GL_BGRA8_EXT,...) here returning PIPE_FORMAT_R8G8B8A8_UNORM rather than PIPE_FORMAT_B8G8R8A8_UNORM

16:48 <mntirc> > That could be fixed by reordering the corresponding mesa format order in this table. This is what the second patch does

18:03 <daniels> mntirc: oh man that is a great find ... and not great that it's there :\

18:04 <daniels> kusma1: ^ think this one is for you - I guess we need to have separate tables for the mappings so we don't have RGBA/BGRA conversions for no reason?

18:12 <mntirc> daniels: indeed firefox is really snappy now

18:28 <urja> is that problem a thing only for RK3588 (Valhall?) or for all panfrost GPUs?

19:14 <alyssa> urja: probably all

19:14 <alyssa> would explain a lot about midgard misery back in the day..

19:42 <mntirc> :0

19:48 <urja> ... i should update & patch mesa for my personal RK3288 distro, then :P

20:12 <HdkR> Someone should really add a one-time log to the software conversion fallbacks in mesa. At least get a log somewhere that software fallback has occured. Freedreno hit the same problem a couple times this last year.

20:38 <alyssa> ...speaking of ancient hardware, anyone want an odroid go advance?

20:38 <alyssa> (mali-g31, the vacuum cleaner gpu)

20:42 <HdkR> Oops, I tossed all mine when I moved.

20:42 <alyssa> HdkR: oh great can I ship you back the one you sent me in 2020 then? :P

20:42 <HdkR> Oh perfect, looks like you have one to throw away :)

21:54 <linkmauve> Which generation is that? I have a 7 and a 10 so far.

21:54 <linkmauve> Mali-G52 and Mali-G610.
