VC4
|
||
|
|
===
|
||
|
|
|
||
|
|
Used on Pis 0-3 and very well documented.
|
||
|
|
|
||
|
|
There are two drivers for it: an open-source one (vc4) and a closed-source,
|
||
|
|
legacy one (bcm).
|
||
|
|
|
||
|
|
## New Driver (vc4)
|
||
|
|
|
||
|
|
As of today, users have to enable it manually on Raspbian,
|
||
|
|
|
||
|
|
Usually, too slow to be used on Pis 0-1.
|
||
|
|
|
||
|
|
Very good integration with the Linux standard ecosystem, both X11 and KMS/DRM.
|
||
|
|
|
||
|
|
## Legacy Driver (bcm)
|
||
|
|
|
||
|
|
As of today, the default driver on Raspbian.
|
||
|
|
|
||
|
|
The only realistic option for Pis 0-1: it uses a coprocessor (other than the
|
||
|
|
main CPU and the main 3D core), and so it can offload some of the work from
|
||
|
|
the CPU.
|
||
|
|
|
||
|
|
No interaction with the X11 desktop.
|
||
|
|
|
||
|
|
## Known Limitations
|
||
|
|
|
||
|
|
- 3D on Godot 3.x only works with the vc4 driver.
|
||
|
|
|
||
|
|
- 2D particles on Godot 3.x don't work.
