Hallo,
as a software developer at the company "imed medical" in Neu-Ulm" I am working with the intel graphics driver
under Debian.
The aim is to output continuous 2D images with the "libdrm" graphic library on the screen. We use the Intel i915 driver.
Since I'm not so familiar with the Intel graphics driver (framebuffer, DRM) unter Debian, I would be verry happy about tips
and examples to get familiar with this topic.
I have already downloaded, compiled and installed the libdrm 2.4.94. I have also implemented the examples from 'modeset'
and I am able to display a png file on the screen.
But to process the images afterwards, we need access to the GPU, maybe GEM ??? Are there any examples or docs to help
me get used it?
Thank you very much.
Bests regards,
Horst Balthasar

For a simple bare-metal (i.e. no compositor/desktop environment like X, wayland or similar) look at kmscube. Contains everything you need for accelarated rendering with just the kernel. Plus mesa, but you really, really, really don't want to write your own rendering driver :-)
