I just had a similar issue with a different driver and remembered your postIf the S bits in the infoframe are 0 the display may under- or overscan the the image (Although the spec says it should behave the same if no infoframe is present). If it is set to 2 the display should underscan the image, so I'd be interested to see if the following patch changes the displays behavior for you. --- a/drivers/gpu/drm/nouveau/nouveau_hdmi.c +++ b/drivers/gpu/drm/nouveau/nouveau_hdmi.c @@ -147,7 +147,7 @@ static void nouveau_hdmi_video_infoframe(struct drm_encoder *encoder, struct drm_display_mode *mode) { - const u8 Y = 0, A = 0, B = 0, S = 0, C = 0, M = 0, R = 0; + const u8 Y = 0, A = 0, B = 0, S = 2, C = 0, M = 0, R = 0; const u8 ITC = 0, EC = 0, Q = 0, SC = 0, VIC = 0, PR = 0; const u8 bar_top = 0, bar_bottom = 0, bar_left = 0, bar_right = 0; u8 frame[20];
No change. BTW, I've been grinding ahead with the EDID quirk infrastructure changes that I discussed in my previous note. I'd prefer not to waste huge amounts of my less-than-copious free time, so please speak up if you have any objections.
