First, Ken,
Unfortunately our letters crossed in the mail (so I had been tracking down
all alone).
Thank you for your configuration sample and overall
help.
Now back to the "tracking down" I promised in my previous post.
To summarize the situation.
System: 32-bit BLFS, init (no systemd), i915 intel, 4.0.1
Finally, I got to the bottom of my "missing" fbcon module (the problem, in
general).
The kernel config developers (could be them "systemd" guys?) threw me a
curve:
By changing the
Device Drivers
Graphics support
Frame buffer Devices
Support for frame buffer devices (CONFIG_FB)
from Y to M,
I got my fbcon module back.
=== 3.19.1
With "Support for frame buffer devices" = Y
the module 'fbcon.ko' IS created!!!
(as had been created for many previous kernels)
=== 3.19.3
With "Support for frame buffer devices" = Y
NO LONGER creates module 'fbcon.ko' !!!
The framebuffer console support is created "statically" (as they say).
=== 4.0.1
Same as 3.19.3 (and for many kernel versions to come)
Note:
The new situation (3.19.3+) started when the kernel founding fathers decided
it was time to bring the reality in line with the
'/linux-x.y.z/Documentation/fb/fbcon.txt'
words (i.e., Y -> static, M -> module).
With renewed apologies for taking this long to untangle the situation,
