<HdkR> Alright. Now that I'm getting settled in to the new job and I'm now doing time budgeting for work. I'm going to budget ~10 hours/week to panfrost

<HdkR> Should make development more consistent
<alyssa> Hooray!
<alyssa> HdkR: Bifrost compiler?
<HdkR> Aye

<shenghaoyang> Is compositing known to be a bit wonky?
<HdkR> Probably more of an issue of the compositor using features that aren't yet fully working in panfrost

<shenghaoyang> Makes sense. Most drm stuff works but sway / weston and friends are filled with black voids once you start making them draw different elements

<daniels> right, you have to forcibly disable the EGL_EXT_buffer_age extension to make it work

<HdkR> I'm very quickly running out of plugs. I need to make some sort of 12v barrel plug power rail

<alyssa> HdkR: lol
<HdkR> alyssa: I've got all the parts coming to me to make a 10-20 port 12v barrel plug supply
<HdkR> :P
<HdkR> Will allow me to use a single 200/250w power supply to power all these things
<alyssa> Uh-huh
<alyssa> ..Why? :P
<HdkR> Because the like 15 wall warts are taking up too many plugs
<HdkR> and they are all 12v
<HdkR> and they all pull like 2A max
shenghaoyang has joined #panfrost
<shenghaoyang> Though there are 12V barrel plug splitters...
<shenghaoyang> And I have one beefy mean well desktop adapter powering a bunch of network gear off that
<HdkR> eh :P
<shenghaoyang> off-the-shelf because soldering together a bunch of plugs is a chore :|
<alyssa> ...and risky
<HdkR> I mean, if you don't know what you're doing anyway :P
<shenghaoyang> the wago terminal blocks are kinda useful if you can hide them though
<HdkR> It's going to end up being a hobby box with a bunch of barrel plugs mounted to the side with a 6pin molex connector linking to the outside world for power
<shenghaoyang> Guess you could call it a patch panel for barrel plugs...
<HdkR> :D
<urjaman> 6-pin?
<HdkR> Power supply I've chosen uses a standard 6pin Molex ATX power connector
<shenghaoyang> But good luck with the soldering since I presume the female barrel jacks don't come pre wired up :P
<urjaman> i'd know 4-pin or 8-pin for the ATX CPU power, or ...
<urjaman> ah the one for PCIe extra power?
<HdkR> Yea, same for PCIe power but as an external brick which is interesting
<HdkR> eh. I'm fine with soldering
<shenghaoyang> eh? Flux always manages to stir up the allergies... lucky you, you get to save some $ :P
<urjaman> https://www.ebay.com/itm/AC-110V-220V-TO-DC-5V-12V-24V-Switch-Power-Supply-Driver-Adapter-LED-Strip-Light/152134115704 yeah i'd have just picked one of these :P (the 12V 20A one would fit what you're doing)
<urjaman> (they're kinda starting to appear randomly around here ... there's one 12V 15A one just set up to run my UPS-like 12V system (screwed it up to 13.8V), an another 24V 5A one powering ... something weird :P (PC Engines APU1 made into a PC..), and one 12V 20A one in the 3D printer...)

<urjaman> .... apparently i accidentally got my C201 tree build-tested by a kbuild test robot by linking to it for totally different reasons in one email thread...
<alyssa> urjaman: Nice.
<hanetzer> heh
<milloni> haha
<milloni> just wondering - panfrost is an unofficial driver, i assume the official mali driver is proprietary
<milloni> so if i get something like a bsp for rock pi 4 https://github.com/radxa/rockchip-bsp.git
<milloni> which has RK3399
<stikonas> well, it wouldn't have panfrost for sure
<milloni> does it have a binary mali driver blob in the kernel tree?
<stikonas> mali kernel driver is actually open source
<milloni> or how does that work?
<stikonas> blob is for userspace
<milloni> oh
<milloni> didn't know
<milloni> good thing i asked i would have never found out
<milloni> out of interest, is there a reason for writing panfrost's own kernel component
<milloni> given that the official one is open source?
<milloni> why not just write the userspace part?
<stikonas> well, simpler code
<stikonas> no licensing problems
<stikonas> i.e. you can't include GPL2 headers in mesa
<urjaman> and also one that is upstreamable
<stikonas> hmm, any ETA for upstream? I guess 5.2 is too early...
<milloni> hah
<milloni> urjaman: can't improve the official one enough to be upstreamable?
<milloni> btw is it because of gpl that they *had to* release the source code for the kernel space part?
<urjaman> honestly i havent read mali_kbase that much, but just based on the little i've seen ... it's ... well what you would expect :P
<milloni> interestingly i just got a rockpi 4 board
<milloni> running their standard bsp (so official mali driver i suppose?)
<milloni> and my monitor keeps resetting
<milloni> but maybe it's missing the userspace part?
