We use the kernel module as a way to easy the upgrade of GPU driver
releases. If using the built-in the Linux kernel version needs to
match the GPU driver release while if using the external kernel
module, this is not a requirement.
Another reason is that the external kernel module bring fixes we do as
community.
OK, so I think I will disable the built in version and use the external
kernel module.
Secondly, in the tmp/work/…/imx-gpu-viv directory there is a file called
imx-gpu-viv-6.2.4.p4.0-aarch32.bin and likewise in
tmp/work/…/imx-gpu-g2d there is a imx-gpu-g2d-6.2.4.p4.0-arm.bin. I
presume that these are some kind of firmware file but as far as I can
see they aren’t making it into the file system on the target. Do I need
to do something with them?
The version used depends on the target you are building for.
I am building for a Boundary Devices Nitrogen 6 Lite board (i.MX6 Solo)
using Yocto and the linux-boundary-4.14 kernel recipe.
We seem to be having really poor performance with canvas events in our
HTML5/CSS front end and some of the benchmarks[1] we have run only seem
to make 10fps.
