<tomeu> alyssa: what should we do regarding the clear regressions that got into master? revert, paper tests over, push a fix, ...?

<tomeu> hrm, when using AFBC for shared wayland buffers, we get a lower glmark2 rate
<tomeu> than with linear

<tomeu> bbrezillon: found this crash here: http://paste.debian.net/1090256/
<bbrezillon> tomeu: hm, I had assumed surf could not be NULL in that case
<tomeu> yeah, I don't know why that's the case
<tomeu> ah, guess it's a FBO?
<bbrezillon> actually, I originally had the code in an if (surf) {} block
<bbrezillon> and got rid of it :-/
<theperfectpunk> Hi I've enabled panfrost in kernel but am getting this in dmesg https://pastebin.com/w1Ahj4ZB
<theperfectpunk> There is no error message associated with the failed gpu init, I don't know what could've gone wrong
<bbrezillon> tomeu: I let you send the patch, I'll add my R-b
<tomeu> theperfectpunk: have you figured out what in the kernel is causing the "Fatal error during GPU init" ?
<tomeu> bbrezillon: ok
davidlt has quit [Ping timeout: 245 seconds]
<theperfectpunk> It isn't upstreamed yet
<tomeu> theperfectpunk: have you talked with narmstrong about it? maybe he's fine with you submitting it
<theperfectpunk> yes he was one of the people to suggest it, I could talk to him about it
<theperfectpunk> tomeu: are we sure the current pastebin is not related to previous problem?
<tomeu> theperfectpunk: not sure I get the question. I think the patch you pointed to addresses the error in the pastebin
<theperfectpunk> tomeu: this is the new dmesg https://pastebin.com/w1Ahj4ZB, I no longer get the GPU fault, but the GPU fails still fails to init.
<tomeu> theperfectpunk: ok, are you able to debug the kernel?
<tomeu> bbrezillon: sent, please add r-b and push if it looks good to you
<bbrezillon> tomeu: don't have W permission yet
<tomeu> bbrezillon: ah, have you started the process already?
<bbrezillon> tomeu: who should I ask to?
<bbrezillon> nope
<theperfectpunk> tomeu: I'll just recompile the kernel to enable kgdb
<tomeu> not sure what's the process these days
yann has joined #panfrost
<theperfectpunk> tomeu: I haven't debug a kernel before , I'll see the docs and find something related to the issue
<tomeu> theperfectpunk: yeah, I think you should look at adding printks in the code path that leads to that "Fatal error during GPU init" message
<tomeu> so you find the exact cause
<tomeu> theperfectpunk: but this is something more for #linux-amlogic I think
<tomeu> for now, most development on panfrost is done on rockchip
<theperfectpunk> tomeu: ok thanks
