Without fonts, this fails to link:
drivers/gpu/drm/clients/drm_log.o: in function `drm_log_init_client':
drm_log.c:(.text+0x3d4): undefined reference to `get_default_font'
Select this, like the other users do.

In order to keep user-space compatibility, we want in certain

use-cases to keep leaking the fbdev physical address to the
|
|
user-space program handling the fbdev buffer.
|
|
This affects, not only, Amlogic, Allwinner or Rockchip devices
|
|
with ARM Mali GPUs using a userspace Blob.
|
|
This option is not supported by upstream developers and should be
|
|
removed as soon as possible and be considered as a broken and
|
|
legacy behaviour from a modern fbdev device driver.
|

|
|
Please send any bug reports when using this to your proprietary
|
|
software vendor that requires this.
|

If in doubt, say "N" or spread the word to your closed source
|
|
library vendor.
