05:59 <bbrezillon> alyssa: depends how you retrieve the pointer, if you use container_of() that should work no matter where you place the base field :)

06:01 camus is now known as kaspter

06:02 <bbrezillon> tomeu: still not entirely happy with the locking

07:08 <tomeu> bbrezillon: I see it as more of a convention, so it's easier to see at a first glance what other struct one "inherits" from

07:26 guillaume_g has joined #panfrost

07:39 <bbrezillon> tomeu: except when you inherit from 2 structs :P

07:40 <bbrezillon> anyway, I think it doesn't hurt to add a comment to make that even more obvious

07:44 <daniels> bbrezillon: awesome work btw, thanks for chasing all that down

07:44 chewitt has joined #panfrost

07:51 <bbrezillon> daniels: thanks, but it doesn't seem to fix the problem I was after https://gitlab.freedesktop.org/mesa/mesa/issues/2108 :-(

10:26 <lvrp16> tomeu: what is the backstory for readpixels req test on t820?

10:27 karolherbst has joined #panfrost

10:28 <tomeu> lvrp16: we'd need to capture a trace of the blob running that test on t820

10:28 <tomeu> that would be probably enough

10:30 <lvrp16> tomeu: on android or linux? I don't know if there is a Linux blob.

10:32 <tomeu> lvrp16: on android would be fine I think

10:37 <tomeu> lvrp16: the trace can be produced with https://gitlab.freedesktop.org/panfrost/panloader/

14:02 <bbrezillon> robmur01, tomeu: would be great if you could have a look at the panfrost fixes I just posted

14:02 <bbrezillon> (and I realize I did not Cc robmur01)

14:13 <robmur01> bbrezillon: no worries, I watch dri-devel ;)

14:14 <robmur01> I can trivially reproduce page faults when kmscube stops on a super-slow GPU, so it should be easy to tell...

14:17 <alyssa> tomeu: I don't know if panloader still works on android

14:18 <alyssa> It did, years ago. That likely has broken since..

14:20 <tomeu> hmm, wonder what our options are for t820

14:21 <alyssa> I.. thought? there was a linux image for s912 floating around.

14:21 <alyssa> chewitt: ^^?

14:21 <tomeu> with an android ddk used via hybris?
