tautologico: well the video pipeline is designed to be dial purpose, it can be configured to accept rgb data, like the UI pipelines, or YUV data, the others only handle RGB, i haven't found any disadvantages to using the video pipeline for UI, other than the fact that it uses it up, leaving it unavailable for separate video rendering
<catphish>
it seems to be just better than the others

<jernej>
catphish: there is only one drawback of VI channel on H3 - it doesn't support alpha channel
<jernej>
but I guess this doesn't matter for you
<catphish>
it's always the bottom layer, so alpha isn't useful, right?
<jernej>
it doesn't have to be, you can configure zpos between channels
netlynx has quit [Ping timeout: 240 seconds]
<catphish>
oh ok, well in any case it's not important to me as this will likely be the only channel i use :)
<KotCzarny>
catphish: overlays are nice, you will need mouse pointer maybe? hud? fps counter? tape selector?
<catphish>
yeah i was just thinking i could add those, sounds like i probably can, if i use video as the bottom layer, then use (smaller) additional ui layers for overlays
<catphish>
no need to scale those eiter, they can run at native resolution
<catphish>
go video layer (scaled low resolution game), then ui layer (native resolution overlays with opacity)
<catphish>
*so
<catphish>
right now my cpu/memory performance blows colossaly, i think because i'm running everything at 24MHz (feels more like 12), i'd better attack that next
<KotCzarny>
we had 7.19MHz on amiga500 and we were happy
<catphish>
but it's not nearly fast enough to render 1,000 x 16x16 sprites per frame (61MB/s) so needs some clocks adjusting

fixed my performance issues, code was running from uncacheable dram, which i guess means no icache, so the cpu was spending much of its time waiting for instruction fetches
<catphish>
enabled cache on the appropriate memory, super fast now

<catphish>
it glosses very quickly over the subject of "non-cacheable", but i don't see why non-cacheable memory would still be cached in the inner icache
<catphish>
but i believe you if you say that's the case
<catphish>
in any case, i enabled caches that seemed appropriate and it's now much happier

plaes: apritzel: any ideas why https://lists.denx.de/pipermail/u-boot/2018-December/352536.html has died and not been applied? we're on teh verge of going out with a new uboot release that is borked on these boards, and I thought there was agreement that revert was the right step
<karlp>
