Message-ID: <CAD1M060ucNEjPceeK9R2s4drkZE1EWEadB1JtcUmnfuNx24zkA@mail.gmail.com> Date: Tue, 6 Oct 2015 14:52:25 -0700 From: Pushpal Sidhu <psidhu@...eworks.com> To: DRI mailing list <dri-devel@...ts.freedesktop.org> Cc: linux-kernel <linux-kernel@...r.kernel.org>, "linux-arm-kernel@...ts.infradead.org" <linux-arm-kernel@...ts.infradead.org> Subject: i.mx6 video out in mainline Hi All, I'm attempting to use a standard fb console (using the imx6qdl-gw54xx.dtsi), but I find that it only draws to the 1024x768p portion of the screen. This is also true when running the userspace tool fb-test. When I $(cat /sys/class/graphics/fb0/modes), I see only the 1024x768p resolution there. I verified that the edid read from the monitor is correct, and that all of it's modes were properly read (in the drm_mode_std function and enumerated in /sys/devices/soc0/display-subsystem/drm/card0/card0-HDMI-A-1/modes), but I can't figure out how to choose a different resolution. I've also verified that dpms is 'On'. The monitor appears to think that a 1080p signal is coming in, which might have to do with the virtual size being set to 1080p. I should note that I'm not running X11. Is there something I am missing that's required for changing framebuffer resolutions?
