This is an initial implementation of HDMI 3D mode support for the nouveau kernel driver. It works on all of the hardware that I have available to test at the moment, but I am unsure as to the overall approach taken for setting HDMI InfoFrames, there's no support for g84 or gf119 disps, and the criteria for enabling stereo support for an output seems a bit iffy. The first four patches arrange to set the HDMI InfoFrames for gt215 and gk104 disps, and provide the parsing side of support for g84 and gf119 disps. The fifth patch remo...

HDMI 3D mode support, round two. Revisions include no longer dealing with audio InfoFrames, passing infoframe data to NVKM as bags of bytes rather than as data pre-packed for the hardware, more-normal return value checking for drm_hdmi_*_infoframe_from_display_mode() results, Frame-Packing mode support, more-principled logic for enabling stereo mode support on a connector, and support...

Now that we have mechanism by which to pass mode-dependent HDMI InfoFrames to the low-level hardware driver, it is incumbent upon us to do so. Experimentation on a gt215 device suggests that the Audio InfoFrame is not required here, possibly being provided by the HDA device when necessary (because where else would it come from?).

I have bugzilla'ed a problem with the 3.3 kernel and my 1920x1200 LCD display here: https://bugzilla.redhat.com/show_bug.cgi?id=806091 Since the InfoFrames appear to be confusing my display, I'm looking for a way to disable them. Is it possible to use the override_conntype parameter to make the driver treat the DisplayPort connector as a DVI connector (which would presumably stop it from sending the InfoFrames)? I can't find any documentati...

Hi. (sorry for non-threaded reply, I expected to receive my own "git send-email"-generated post) This patch is an RFC, with at least 3 things to change before it could be committed: - commented-out NV84_DISP_SOR_HDMI_PWR_STATE_ON test: what is this needed for ? I couldn't find an equivalent in my trace, but maybe I just didn't do what is needed to generate these writes -

The nouveau driver, in the Linux 3.7 days, used to try and set the AVI InfoFrame based on the selected display mode. These days, it uses a fixed set of InfoFrames. Start to correct that, by providing a mechanism whereby InfoFrame data may be passed to the NVKM functions that do the actual configuration. At this point, only establish the new parameters and their parsing, don...
