From: Dave Airlie <airlied at gmail.com> [ Upstream commit 7854ea0e408d7f2e8faaada1773f3ddf9cb538f5 ] This func ptr here is normally static allocation, but gsp r535 uses a dynamic pointer, so we need to handle that better. This fixes a crash with GSP when you use config=disp=0 to avoid disp problems.

This is a collection of nouveau debug prints, memory leak, a very annoying race condition causing system hangs with prime scenarios, and a fix from Lyude to get the panel on my laptop working. I'd like to get these into 6.7, Dave.

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 removes code that sets up the "mandatory"...

Just like how the P50 will occasionally leave the disp's core channel on before nouveau starts initializing, it will occasionally do the same thing with the rest of the dmac channel in addition to the core channel. Example: [ 1.604375] nouveau 0000:01:00.0: disp: outp 04:0006:0f81: no heads (0 3 4) [ 1.604858] nouveau 0000:01:00.0: disp: out...

If init doesn't run then disp->outp might not be initialized, resulting in an oops.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=76319 Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu> --- It's unclear to me whether GF11x devices actually support this, but the disp "split" is at nvd0, so I went with that. The marketing docs are fairly unclear. However most of them don't actually have DP in the first place, so it may not be a huge issue. I don't have the hardware for testing this myself, but hopefully someone can verify that this doesn't...
