Having trouble with two active wscons drivers, wskbd stops working on console

[Alain Runa <alain74%gmx.net@localhost>]

Hello all,

I’m currently revising my wscons based driver for the MNT Z9000 to make it compatible with the newest v1.13 firmware. The driver is almost finished, but I’m experiencing an issue with the wskbd. It stops working if two wscons display drivers are active in the kernel. For example, if I include amidisplaycc (Amiga native) and zz9k_fb (ZZ9000) in the kernel, the zz9k_fb gets the console at wsdisplay0 but the console does not respond to any key presses from the keyboard. On the other hand, if I only include amidisplaycc or zz9k_fb alone in the kernel, keyboard works fine on the console.

Here the kernel output extract in bad case (amidisplaycc + zz9k_fb):

kbd0 at mainbus0: CIA A type Amiga
wskbd0 at kbd0 mux 1
ms0 at mainbus0
wsmouse0 at ms0 mux 0
wsmouse1 at ms0 mux 0
amidisplaycc0 at mainbus0: Amiga custom chip graphics 
wsdisplay1 at amidisplaycc0 kbdmux 1
wsmux1: connecting to wsdisplay1
wskbd0: connecting to wsdisplay1
…
zz9k0 at zbus0 pa 0x48000000 man/pro 28014/4: MNT ZZ9000 Zorro III (HW: 0.0, FW: 1.13)
zz9k0: Hardware status <Ccore: 52.6 C, Tcore: 0.99 V, Vaux: 1.77 V>
zzfb0 at zz9k0: Framebuffer resolution: 1280x1024p60, depth: 8 bpp (8-bit LUT)
wsdisplay0 at zzfb0 kbdmux 1: console (default, vt100 emulation)
wsmux1: connecting to wsdisplay0


And here the kernel output extract in good case (zz9k_fb only):

kbd0 at mainbus0: CIA A type Amiga
wskbd0 at kbd0 mux 1
ms0 at mainbus0
wsmouse0 at ms0 mux 0
wsmouse1 at ms0 mux 0
…
zz9k0 at zbus0 pa 0x48000000 man/pro 28014/4: MNT ZZ9000 Zorro III (HW: 0.0, FW: 1.13)
zz9k0: Hardware status <Ccore: 52.1 C, Tcore: 0.99 V, Vaux: 1.77 V>
zzfb0 at zz9k0: Framebuffer resolution: 1280x1024p60, depth: 8 bpp (8-bit LUT)
wsdisplay0 at zzfb0 kbdmux 1: console (default, vt100 emulation)
wsmux1: connecting to wsdisplay0
wskbd0: connecting to wsdisplay0


I’m not 100% sure what is going wrong here, but to me it looks like that in bad case, the wskbd0 is still connected to wsdisplay1 (Amiga native) and not to wsdisplay0 (zz9k_fb) which becomes the active console display. I see wsmux1 switching to wsdisplay0 but wskbd0 is not. I’m not sure if it is supposed to do so, but I assume it should.

Is my assumption correct? How do I instruct wskbd that it should switch to wsdisplay0, when zz9k_fb gets initialized?
Or is the problem somewhere else?

Any indication to the right direction would be appreciated.
