Hi, Radoslaw Kujawa told me to send my details here. I built a graphics card for classic Amiga computers (using the Zorro bus) and started writing a NetBSD driver for it. I managed to use it as a wsdisplay console but ran into problems with X and wsfb (Bus error, screenshot attached). The driver sources and kernel config files are here: https://github.com/mntmn/va2000-netbsd I have several problems: 1. Using mntva as console: If I enable the console setup part in my driver and configure GENERIC like this: wsdisplay0 at wsdisplay0 at wsemuldisplaydev ? console ? Then the boot starts on the internal Amiga chipset display and then switches over to my driver's display. But even if I have a working terminal on my card on ttyE0, X or any opening of the file "/dev/ttyE0" will complain about "device not configured". 2. Using amidisplaycc as console: Disabling console setup in mntva.c and configuring GENERIC like: wsdisplay1 at amidisplaycc0 console ? wsdisplay0 at wsdisplay0 at wsemuldisplaydev ? Then my driver will initialize, and the boot console will stay on the Amiga chipset display. After login I can do: wsconscfg 0 This seems to correctly configure /dev/ttyE0 and the gfx card screen is cleared and a white cursor appears. The /dev/ttyE0 file can be opened and X -config ./xorg.conf starts sending ioctls and mmaps to my driver, ultimately crashing with a Bus error though. Can you see anything fishy/wrong in the driver source? Do I have to do any special setup of /etc/ttys or /etc/wscons.conf? Thanks for any input. Cheers, Lukas F. Hartmann (@mntmn)
