Hi, I recently bought a BeagleBoard X15 and started playing with it, the first thing I noticed is despite there is three GPU on AM57x SOC, there is no hardware acceleration in X11 I searched and found that the 3D GPUs are not only proprietary, but TI actually does not support X11 at all ... it is bad because I actually love X11 and want to use it. Then I tried the GC320 2D GPU with TI galcore driver (https://git.ti.com/graphics/ti-gc320-driver) and armada X driver (https://github.com/xobs/xserver-xorg-video-armada with galcore/libGAL) : it works, but sometimes it freezes : actually it freezes everytimes when quitting X. I made some tests with proprietary libGAL (https://git.ti.com/graphics/ti-gc320-libs), and I finally found that either the driver or the userspace lib make the computer freezing.
I decided to look further and discovered that project that aim to open-sourcing Vivante GPU chips Etnaviv is pretty well advanced (https://github.com/etnaviv). The project initially support GCxxx chips in IMX6 and Armada SOC, and I wondered if it could works on AM57x. It appears that it works ! I backported the etnaviv from mainline kernel to use it with the linux 4.4 kernel provided with the default board Debian (http://repos.rcn-ee.com/debian/), and with very little changes, it can be used with Beagleboard X15. More details on how it works in this repository : https://github.com/julbouln/etnaviv_x15 I think it can be really easy to add the support in mainline kernel (some minor changes to DTS + etnadiv driver compatibility) I hope this can be useful !
