Hi folks,
I'd like to get the cairo's gallium backend running again (hasn't been
maintained for a long time and doesn't fit at all to recent mesa).
The main problem I've got here is that gallium API is mesa-internal,
so I'd like to do some steps on making it (semi-)public. I'm aware that
it's still in flux, so we'll have an strict version dependency for
quite some time - but I can live with that for now.
I haven't yet understood, how to the different pieces work together,
so any help is greatly appreciated.
Let's start w/ a simple DRM usecase (no X involved). The big steps
would IMHO be:
#1: open the DRM device, setup fb and crtc
#2: map a framebuffer (in the first steps I'd like to use cairo's
image surface - IOW: softraster - and later move to gallium
operations step by step)
#2: initialize the GPU driver
#3: start sending some render commands to the GPU.
Maybe someone could give me some hints on how these things actually
could look like ?
