Re: Pi 4 - full specification of VideoCore 6

I loose track of what goes on now a days. Currently Microsoft is a great Linux supporter. They put the WSL in Win 10 so that I can run all my favorite Debian things. And build and run whatever I like there. They are introducing the WSL 2 with a real Linux kernel so I can run even more of my favorit...

Re: Pi 4 - full specification of VideoCore 6

An interesting alternative to increasing the performance of the GPU is to focus on power savings and reduce the CPU to something like the Cortex-A55, which is officially the generational successor to the Cortex-A53 used in the 3B. I think the decision to use four big cores, the Cortex-A73, in the p...

Re: Pi 4 - full specification of VideoCore 6

rpi4 it's a good hw for the price...but the gpu it's terrible weak and clearly doesn't match the CPU performance. videocore 6 seems a bit better on real opengl ES workloads than a mali g31 mp2, but no soc manufacturer pair a mali g31 with a high end CPU, they are paired with cortex a35 or cortex a53...

Re: where is the raspbian i386 repo?

1) using a repo from another distribution (even debian buster, which is from raspbian its based) it's not recommend by any means and will probably destroy ANY distribution. 2) I am asking the raspbian x86 repo!

Re: Enabling S3TC texture compresion?

Yeah, it should...but it doesn't. there is a software decompressor on mesa, but its not working for many gallium drivers (panfrost,v3d,vc4,lima...)

ive posted an issue bc of that, but no much help so far.

Re: export a lib on program execution

My idea its to drag the original mesa 13 libs on raspbian and set that as secondary gl libs, because mesa 19 has great features, but has a lot of "regressions" . another idea its just test different mesa builds just for testing porpoise.

Re: export a lib on program execution

Ok, I found this instructions on Anholt wiki: If you're interested in hacking on the Mesa driver, you'll want to build your own copy of Mesa. And since Mesa is a system component and you won't want to break your desktop if you make a mistake, you will want to do it without replacing your system Mesa...

Re: The dtoverlay=vc4-kms-v3d overlay and memory allocation

I found than cma its at256 by default. I will try your cmd line. But maybe the overlay will ignore that by default because the max cma option inside the overlay dtb its 256. I will try to edit the dtb if thats the case. Thanks!
