 |
|
Hi,
I'm installing a full Gentoo on my Raspberry Pi 3. I've installed Mesa 12.0.1 drivers which seem include drivers for VideoCore 4 (with VIDEO_CARDS set with "vc4"), but if i read the Gentoo Wiki i can see this :
| Quote: | | The ARM side libraries for interfacing to Raspberry Pi GPU are included in a package raspberrypi-userland. Which includes the Video Core tools, GLES2, EGL, openmax and openVG libs that support the Raspberry Pi GPU. |
Which is the best choice ? Or it's recommended to install both without any conflicting problem ?
Thanks in advance. |

That is a good question. I set up my Raspberry Pi 3 with raspberrypi-userland before Mesa included the VideoCore 4 libraries, with many custom ebuilds to account for the differences. If mesa now includes VC4, perhaps the process is much easier.
I am honestly a bit hesitant to change anything after taking so much time to make things work as it is. Maybe I will use my Raspberry Pi 2, which I am not using at the moment, for testing this. Hopefully someone else will know the answer to your question, though. |
