Dear kernel / GPU enthusiasts!
This list is listed in the kernel MAINTAINERS file for GMA500 GPU kernel module.
Just to avoid disappointment later on: For the gma500 driver it's essentially unmaintained, but we do take patches if they show up.
My message is either a call for help (not a mission-critical issue) or troubleshooting information useful to fix an outstanding issue in the GMA500 kernel driver?
This GMA3650-GPU-based system with a self-supported Linux distribution boots OK in all cases (ssh access fine when no console).
With the HAI monitor (actually a 7 inches monitor marketed for the cinema industry, the edid information reporting a wrong display size), the frame buffer console is fine, i.e. from the boot log:
[ 1.506269] fbcon: psbdrmfb (fb0) is primary device
Accordingly, there are two entries in the /sys/class/vtconsole/ directory, names "(S) dummy device" and "(M) frame buffer device".
Unfortunately, with two ASUS monitors, the above line in the boot log never appears. And the console turns blank early in the boot process. A single entry appears in /sys/class/vtconsole/, i.e. vtcon0/name -> "(S) VGA+".
In either case Xorg starts fine and switching between ctrl-alt-f7 and ctrl-alt-f1..6 (either console for HAI or blank for ASUS) works fine.
Looking in the kernel source tree, 'psbdrmfb' is a frame buffer name appearing once in the GMA500 GPU source code.
This what I found in my patient troubleshooting.
Uh this is strange, the gma500 driver should still load all fine and register that framebuffer driver. I think the only case where gma500 loads but psbdrmfb isn't set up is if it doesn't detect any outputs. I'd test these monitors with some other linux system first (they might be simply too broken), if that doesn't work you can quirk your system with the video boot parameter perhaps:
https://dri.freedesktop.org/docs/drm/fb/modedb.html
Cheers, Daniel
See below:
two boot log excerpts (grep'ing gcc|drm|gma5|console|fbcon|D2550 -C 2) for the 'pass' and 'fail' boot sequences;
three edid reports for the (pass) HAI monitor and two (fail) ASUS monitors.
Thanks in advance, and best regards!
