[PATCH] ARM: shmobile: defconfig: Restore graphical consoles

[PATCH] ARM: shmobile: defconfig: Restore graphical consoles

[Geert Uytterhoeven]

As of commit f611b1e7624ccdbd ("drm: Avoid circular dependencies for
CONFIG_FB"), CONFIG_FB is no longer auto-enabled.  While CONFIG_FB may
be considered unneeded for systems where graphics is provided by a DRM
driver, R-Mobile A1 still relies on a frame buffer device driver for
graphics support.

Restore support for graphics on R-Mobile A1 and graphical consoles on
DRM-based systems by explicitly enabling CONFIG_FB in the defconfig for
Renesas ARM systems.

Does anyone still care about the Armadillo board ?

This being said, I think CONFIG_FB should be added , but for a different
reason. There's no KMS console driver, so the only option we have today,
even when a KMS driver is available, is to go through FBDEV emulation,
which requires CONFIG_FB to be enabled.

I do. It's my only Renesas board with graphical output ;-)

That's covered by "Restore [...] graphical consoles on DRM-based
systems", right?

I recommend a VGA or HDMI monitor :-) The sh-mobile-lcdcfb driver is
unmaintained. If nostalgia is a big enough drive factor, you could try
converting R-Mobile A1 to the shmob-drm driver :-)

I had read the commit message as implying that a graphical console can
be available without FB when a KMS driver is available.

I'll do so as soon as drivers/gpu/drm/shmobile has gained DT support...

The fbdev driver doesn't have DT support either. And patches are welcome
for shmob-drm ;-)

Same answer for DRM and FBDEV, it's about whether you want a graphical
console or not. The underlying API doesn't matter (I wish we had a
kmscon).
