Subject: [PATCH] drm: Drop select FRAMEBUFFER_CONSOLE for DRM_FBDEV_EMULATION
Date: Fri, 4 Aug 2023 14:51:43 +0200 [thread overview]
Message-ID: <20230804125156.1387542-1-javierm@redhat.com> (raw)
The commit c242f48433e7 ("drm: Make FB_CORE to be selected if DRM fbdev
emulation is enabled") changed DRM_FBDEV_EMULATION from 'depends on FB'
to an effective 'select FB_CORE', so any config that previously had DRM=y
and FB=n now has FB_CORE=y and FRAMEBUFFER_CONSOLE=y.
This leads to unmet direct dependencies detected for FRAMEBUFFER_CONSOLE
as reported by Arthur Grillo, e.g:
WARNING: unmet direct dependencies detected for FRAMEBUFFER_CONSOLE
Depends on [n]: VT [=n] && FB_CORE [=y] && !UML [=y]
Selected by [y]:
- DRM_FBDEV_EMULATION [=y] && HAS_IOMEM [=y] && DRM [=y] && !EXPERT [=n]
Arnd Bergmann suggests to drop the select FRAMEBUFFER_CONSOLE for the
DRM_FBDEV_EMULATION Kconfig symbol, since a possible use case could
be to enable DRM fbdev emulation but without a framebuffer console.
Fixes: c242f48433e7 ("drm: Make FB_CORE to be selected if DRM fbdev emulation is enabled")
Reported-by: Arthur Grillo <arthurgrillo@riseup.net>
Closes: https://lore.kernel.org/dri-devel/20230726220325.278976-1-arthurgrillo@riseup.net
