Hello, I am running mainline(ish) 3.16.1 on a custom i.MX6 board which is working very well including a basic rgb parallel display and fb support through mxc_lcdif etc which i brought forward in /drivers/video/mxc/.
I would like to get an accelerated graphics stack running and am looking for some advice/guidance on getting the vivante gpu up and running with a basic xfce or similar windowed environment.
Currently I am simply using qt 4x in qws mode and I would like to get accelleration working before I start looking at qt5.
I am using oe to generate my angstrom image, but the vivante kernel support doesn't seem to be available for mainline and there seems to be a myriad of drivers/files and modifications needed to get this going.
Specifically, I am looking for a list of 'requirements' that need to be met so that I can tackle them one at a time but haven't found any documentation outlining all of the requirements.
1. /drivers/gpu/drm requirements?
2. /drivers/gpu/ipu_v3 requirements?
3. vpu power configuration?
4. gpc gpu/vpu clocks?
5. vivante kernel drivers?
6. user-space drivers required?
7.device tree bindings required in my dts files?
8. other things that I probably forgot....
bonus question, since I currently am NOT using the gpu, how can I confirm that is is not using up extra power unnecessarily until I get this sorted out?
I know that this is a very board question/set of questions, so don't feel the need to answer everything but please chime in if you have any ideas or questions!
Thanks everyone
Brent
