Subject: [PATCH 2/3] gpu/drm: ingenic: Switch emulated fbdev to 16bpp
Date: Sun, 16 Feb 2020 12:58:10 -0300 [thread overview]
Message-ID: <20200216155811.68463-2-paul@crapouillou.net> (raw)
In-Reply-To: <20200216155811.68463-1-paul@crapouillou.net>
The fbdev emulation is only ever used on Ingenic SoCs to run old SDL1
based games at 16bpp (rgb565). Recent applications generally talk to
DRM directly, and can request their favourite pixel format; so we can
make everybody happy by switching the emulated fbdev to 16bpp.
