ChanServ changed the topic of #lima to: Development channel for open source lima driver for ARM Mali4** GPUs - Kernel has landed in mainline, userspace driver is part of mesa - Logs at https://people.freedesktop.org/~cbrill/dri-log/index.php?channel=lima and https://freenode.irclog.whitequark.org/lima - Contact ARM for binary driver support!

<paulk-leonov> hi folks
<paulk-leonov> we're looking for a way to accelerate nv12 to nv12 scaling on sunxi
<paulk-leonov> (with hardware)
<paulk-leonov> do you know if that's possible with the GPU?
<paulk-leonov> I think the usual trick to go with 8-bit texture formats
<paulk-leonov> (aka luminance iirc)
<paulk-leonov> but last time we tried I think there were strong alignment requirements
<paulk-leonov> or something like that
<paulk-leonov> does that ring a bell?

<anarsoul> paulk-leonov: hey
<anarsoul> there's 64-byte alignment requirement for textures
<anarsoul> but since colorspace conversion via shader works in mpv I guess you can do something similar
<anarsoul> you can also go with R8 format since lima supports it
<anarsoul> not natively though - IIRC it uses L8 internally
