bbrezillon: got back to clearattachments, and wanted to agree with you what to do with those descriptors that depend on the width and height of the fb being known
<tomeu>
this will be also a problem with secondary cmd bufs that have draws but no FB
<tomeu>
in bifrost, we can do the same as with the fb desc and allocate it at record time but emit it at batch close time
<tomeu>
but on midgard, the size of the polygon list BO depends on those

tomeu: I see how it's a problem for secondary cmdbufs, but it should work fine when the clearattachments is recorded in a primary cmd buf
<tomeu>
yeah, the tests I have though issue the clearattachment on a secondary though, once with a fb and then without
<tomeu>
but well, I'm doing clearattachment in order to run more secondary cmdbufs tests :)
<bbrezillon>
tomeu: so you're trying to implement secondary buf support
<tomeu>
yeah, continuing that work
<bbrezillon>
which I think is orthogonal to the clear-attachment thing
<tomeu>
with in turn is needed for some event tests :)
<bbrezillon>
let's try to fix one thing at a time :)
<tomeu>
yeah, well, the deqp-vk seems to like testing all combinations...

tomeu: ok, so the problem is that you don't have a FB bound when the clearattachments is recorded on the secondary cmdbuf
<tomeu>
bbrezillon: yep, when a fb isn't passed to VkCommandBufferInheritanceInfo
<bbrezillon>
tomeu: so, you need the FB desc just on Midgard (when assigning dcd.fb), right?
<bbrezillon>
(BTW, you'll have the same issue when recording draws on a secondary buf)
<tomeu>
yep and yep
<bbrezillon>
tomeu: can we leave that field to 0, and patch it (with pan_merge()) when executing the secondary command buf?

,_, mt8192 will need devfreq hacks too
<macc24>
at least they look to be similar to mt8183 hacks

a disadvantage of developing on a gaming device is that you inevitably end up playing video games on it instead of doing something useful
<alyssa>
naturally.

alyssa: am i allowed to complain if a webpage on duet renders slowly and makes entire ui stutter?
