<daniels> robmur01: oh, that's interesting
<daniels> robmur01: I assume that's with DDK + panfrost.ko? in that case, it should be a great deal more simple to figure out what the difference is between DDK + kbase and DDK + panfrost.ko
<robmur01> daniels: nope, just mainline panfrost - I'm still incapable of even building the DDK at all :)
<daniels> robmur01: heh
<robmur01> from what I've seen, kbase's coherency stuff is pretty much all done in secret behind the rest of the kernel's back
<daniels> woohoo

<robmur01> and I think it might do rather more WRT GPU MMU attributes - we're essentially being as conservative as possible in that regard right now
<robmur01> (although in principle I *think* that shouldn't impact directly on coherency, at least while we're still only doing Midgard LPAE)
* robmur01 thinks...
<robmur01> ...although we might possibly face a hole in the current DMA API if we did want to map GPU-private buffers as ISh/NSh and need to guarantee the underlying memory is CPU-cache-clean for a coherent GPU
<robmur01> (in that situation we'd effectively be behaving like PCI No Snoop, and that's a big ol' can of worms already)

<HdkR> alyssa: I presume you're not using the RockPro64 atm? :P
<alyssa> HdkR: Got the Go Advance sitting here and have a Kevin on the coffee table :)
<HdkR> awesome. I'm going to put a case on the thing so it stops hanging out bare board
<anarsoul|2> :)
<HdkR> I've got too many bare boards out on this shelf
<anarsoul|2> HdkR: it should also keep it cooler
<alyssa> Minutes before XDC "....how long has that been broken for?" "you know what, no time to fix it rn"
<anarsoul|2> aluminum case is a pretty good heatsink
anarsoul|2 is now known as anarsoul
<HdkR> I have the big chonky heatsink on it currently so it isn't too bad already
<HdkR> Always room for improvement though
<HdkR> Chassis installed on the RockPro64
<macc24> alyssa: is go advance usable with panfrost?
<HdkR> Only if you like the bleeding edge 90 degree rotated screens
<macc24> how to help with making it work?
italove has joined #panfrost
<stikonas> is rockpro64 not overheating for you without fan?
<HdkR> I put zero load on it
<stikonas> oh ok...
<stikonas> I put Gentoo on it...

<robclark> HdkR: for 90deg rotated screen, https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/3767
kinkinkijkin has joined #panfrost
<HdkR> robclark: Sadly the scope of the rotated screen lives outside of panfrost. The DC on the GoA can do the rotation for "free"
<robclark> ahh, if you can do it on display, that does make the gpu driver part easier
