Subject: [PATCH 0/3] Support fast framebuffer panning for i.MX6
Date: Wed, 13 Jul 2016 10:11:45 +0200 [thread overview]
Message-ID: <1468397508-5112-1-git-send-email-s.christ@phytec.de> (raw)
Hi,
im currently working on supporting double/tripple buffering for the framebuffer
emulation on the i.MX6. While working on it I noticed that the mainline kernel
does not support some features in the generic drm framebuffer emulation for
framebuffer panning and vsync synchronisation. They are needed for simple
framebuffer applications and some OpenGL libraries using double buffering with
FBIOPUT_VSCREENINFO, FBIO_WAITFORVSYNC and FBIOPAN_DISPLAY.
Any comments?
Kind regards,
Stefan Christ
