alyssa: I had a look at the gator HW counter desc files, and they seem to miss a crucial thing if we want to generate counters table out of them: the counter id
thefloweringash has joined #panfrost
<bbrezillon>
which means we'll have to go through all of them and add IDs. Not sure it's more efficient than writing the desc directly in C (unless we plan to also use those XML files in other apps) :)
<milloni>
good morning, so i've wanted to try panfrost
<milloni>
im going to try on a board similar to rock pi 4
<milloni>
is anyone doing development on this board?
<HdkR>
I think...someone was
<milloni>
TheCycoONE: ^
<milloni>
i'm just trying to figure out the logistics
thefloweringash has joined #panfrost
<milloni>
i suppose i'm getting a custom kernel with the board, but to try panfrost i'll try to put the panfrost kernel tree on it
<milloni>
so i'm wondering if 5.0 has support for that board
<robher>
milloni: mainline should work for it. That's what I use, but I have a rock960c.
<milloni>
hmm okay - so to start hacking on panfrost, i would put need to put the panfrost linux tree and panfrost mesa on it?

<tomeu>
milloni: do you have previous experience using ARM boards?
<raster>
tomeu: hey an. catching up.. as of like the last week can't use nondrm+mali kbase anymore... what i'm trying to find is ... where is a kernel tree i can clone with the current state of things?
belgin has quit [Quit: Leaving]
<tomeu>
raster: I'm afraid that nondrm has been dropped from mesa master
<tomeu>
but the DRM kernel driver isn't working that bad these days :)
<raster>
tomeu: so i noticed. as of about a week back
<raster>
the question tho is... what kernel tree is the "latest and greatest" with that driver already rolled in?
<raster>
panfrost main page doesnt have any details on that
<tomeu>
raster: we are not investing in making it easy for others to try it out because we are working hard to have it merged in mainline
<tomeu>
I will push a fix to that branch in a bit that makes it work even better
<raster>
tomeu: oh hidden in a branch :) this is the magic info i needed :)
<urjaman>
"hidden"
<tomeu>
yeah well, at this stage the canonical place is LKML :)
<raster>
well tbh have to even know what linux tree git repo to look at
<raster>
and then which one has which branches...
<raster>
tomeu: argh... that makes it a bit hard to deal with until it's merged :)
<raster>
have to find latest patchset on lkml history...
<tomeu>
yeah, hopefully won't take long :)
<tomeu>
urjaman: I think we may have a bug in how we reset after failed jobs, but the fix I want to push now should avoid those failed jobs in the first place
<raster>
tomeu: yeah. it's just a bad point in time atm
<tomeu>
yep
<tomeu>
but if we hurry up, everything will be in debian in a couple of months :)
<raster>
:)
<raster>
tho userspace still needs work last i looked
<raster>
i did some travelling and was sick so i wasnt able to keep up lately
<tomeu>
well, both kernel and userspace will still need lots of work
<tomeu>
urjaman: pushed
<urjaman>
neat, i'll check it the next time i dabble with the kernel (which might now be sooner, but anyways)
<urjaman>
i was just checking that you were aware of that
<bbrezillon>
alyssa: I started looking at the texture size op, and things start to work (http://code.bulix.org/zuymga-653334), but looks like the HUD is not transparent as it should be
<bbrezillon>
any idea what could cause that?
<tomeu>
cool, thanks

tomeu: no experience using ARM boards, i just borrowed one from a friend, he's walking me through it
<alyssa>
Holy guacascrollback
<alyssa>
bbrezillon: Oh, huh..
<alyssa>
bbrezillon: I'm trying to remember where I got the counter IDs from then
<alyssa>
That file is GPL according to the repo, I don't know why the per-file license notice is missing but GPL code is GPL :P
<alyssa>
raster: Indeed, kbase is legacy now that the Panfrost kernel space is nearing merge.
<raster>
alyssa: asi found out today :)
<alyssa>
I think there's a branch on gitlab.freedesktop.org/panfrost/linux which is the "official" source
<raster>
i checked the mesa commit log and found your commit from like a week ago :)
<alyssa>
...As Tomeu linked
<alyssa>
bbrezillon: I've seen the same issue in mpv, I'm wondering if they're playing games with blending and hitting corner cases there
<alyssa>
bbrezillon: Obviously I don't do code review over pastebin, but that diff there looks good and can probably be merged independent of fixing the rest of the HUD (email it?)
<alyssa>
raster: To be fair, I pushed it only a few days ago, since I was waiting on Tomeu's ack and Linaro Connect slowed things a bit ;)
<bbrezillon>
alyssa: need to take care of different variants of textureSize first
<alyssa>
+1
<raster>
alyssa: i missed connect. was sick :(
<alyssa>
raster: :(
<raster>
alyssa: and yeah... i noticed its so new that the documentation hasnt caught up yet :)
<alyssa>
Oh, shoot, forgot about that!
<alyssa>
Instructions updated, dunno if gitlab will comply and update the site.
<raster>
:)
<raster>
no worries
<raster>
i figured out it was "have to use new kernel driver" by trawling the commit logs
<raster>
but probably good to tell people on the site and then where to get that kernel (what repo/branch)
<raster>
and any speific kernel config that may be needed
<raster>
i've guessed :)
<raster>
i hope i'm right
<raster>
kernel building atm on my rockpro64
<TheCycoONE>
looks updated to me alyssa
<TheCycoONE>
suggestion, add a link from index.html

0:11: L0001: Local storage block 'PLS' uses 20 bytes of storage, maximum allowed size is 16 bytes
<alyssa>
Well, this is interesting
<alyssa>
Since allegedly T760+ can do more than 16
<alyssa>
Not that I understand how that's possible

this and that, and 'not at liberty to disclose more than what's in the driver already' :P

bbrezillon, btw, can mali read perf cntrs from cmdstream? If so, that is probably what you want, rather than kernel interface so you can implement things like the amd perfcntr extension, which wants you to be able to enable/disable counters on per draw rather than per submit/batch basis
