When I enable debug in imx-hdmi.c I see the following: So it's a similar setup to the Cubox-i. > on powerup with HDMI attached: > [ 6.291082] imx-ipuv3 2400000.ipu: IPUv3H probed > [ 6.298370] imx-ipuv3 2800000.ipu: IPUv3H probed > [ 6.310356] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013). > [ 6.317087] [drm] No driver support for vblank timestamp query. > [ 6.324249] imx-drm display-subsystem.11: bound imx-ipuv3-crtc.0 > (ops ipu_crtc_ops) > [ 6.332475] imx-drm display-subsystem.11: bound imx-ipuv3-crtc.1 > (ops ipu_crtc_ops) > [ 6.340616] imx-drm display-subsystem.11: bound imx-ipuv3-crtc.2 > (ops ipu_crtc_ops) > [ 6.349221] imx-drm display-subsystem.11: bound imx-ipuv3-crtc.3 > (ops ipu_crtc_ops) > [ 6.358098] imx-hdmi 120000.hdmi: Detected HDMI controller 0x13:0xa:0xa0:0xc1 > [ 6.365366] hdmi_compute_cts: freq: 48000 pixel_clk: 74250000 ratio: 100 > [ 6.372169] imx-hdmi 120000.hdmi: hdmi_set_clk_regenerator: > samplerate=48000 ratio=100 pixelclk=74250000 N=6144 cts=74250 > [ 6.383971] imx-drm display-subsystem.11: bound 120000.hdmi (ops hdmi_ops) > [ 6.383998] imx-hdmi 120000.hdmi: EVENT=plugin > [ 6.384011] imx-hdmi 120000.hdmi: imx_hdmi_poweron > [ 6.384022] imx-hdmi 120000.hdmi: imx_hdmi_setup vic=0 > [ 6.384031] imx-hdmi 120000.hdmi: Non-CEA mode used in HDMI > [ 6.384038] imx-hdmi 120000.hdmi: final pixclk = 0 > [ 6.402148] imx-hdmi 120000.hdmi: imx_hdmi_setup DVI mode > [ 6.428804] imx-drm display-subsystem.11: bound ldb.10 (ops imx_ldb_ops) > [ 6.490101] imx-hdmi 120000.hdmi: got edid: width[70] x height[39] > [ 6.506191] imx-drm display-subsystem.11: fb0: frame buffer device > [ 6.512596] imx-drm display-subsystem.11: registered panic notifier > [ 6.518947] [drm] Initialized imx-drm 1.0.0 20120507 on minor 0 So at boot, I see this: [ 1.282549] imx-ipuv3 2400000.ipu: IPUv3H probed [ 1.295494] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).

The difference you will notice is that there's the "Console: switching ..." line, which is there because I have fbcon enabled. Therefore, I suspect that it is working as it should - if you enable fbcon, it should automatically initialise. If you don't have fbcon enabled, then it'll probably wait for a userspace DRM driver to bring it up. -- FTTC broadband for 0.8mile line: now at 9.7Mbps down 460kbps up... slowly improving, and getting towards what was expected from it. _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
