similar to: [PATCH 1/3] drm/nouveau/disp: fix HDMI on gt215+

This allows us to advertise more modes especially on HDR displays. Fixes using 4K at 60 modes on my TV and main display both using a HDMI to DP adapter. Also fixes similiar issues for users running into this.

Currently, nouveau doesn't actually bother to try probing whether or not it can actually handle interlaced modes over DisplayPort. As a result, on volta and later we'll end up trying to set an interlaced mode even when it's not supported and cause the front end for the display engine to hang. So, let's teach nouveau to reject interlaced modes on hardware that can't actually

Most of the reason I'm asking for an RFC here is because this code pulls a lot of code out of i915 and into shared DP helpers. Anyway-nouveau's HPD related code has been collecting dust for a while. Other then the occasional runtime PM related and MST related fixes, we're missing a lot of nice things that have been added to DRM since this was originally written. Additionally, the code

This is mainly for dropping interlaced modes on DP connectors if the GPU would otherwise display garbage or EVO timesout. It also adds experimental detection of the HDMI clock limit we currently hard limit depending on the GPU generation. Starting with GF110 GPUs, we can retrieve the limit directly from the GPU and may make the hdmimhz parameter obsolete. Testing this series with 2560x1440 or

small update to my last version I sent out. Patches 3-6 are optional and should only improve detecting the max clocks for HDMI and DP, but they didn't underwent big testing and I am a bit concerned, that it might break detecting the DP limits on some boards.

Ville also pointed out that I got a lot of the logic here wrong as well, whoops. While I don't think anyone's likely using 3D output with nouveau, the next patch will make nouveau_conn_mode_valid() make a lot less sense. So, let's just get rid of it and open-code it like before, while taking care to move the 3D frame packing calculations on the dot clock into the right place.

Now that we've added the hooks that we've needed for this and used them in i915, let's add one more hook (which I could use some feedback on, I'm not sure if it's worth maybe just reworking how we do mode pruning in nouveau instead...) and start using this in our mst ->mode_valid callback to filter out impossible to set modes on MST connectors. Lyude Paul (2):

While I thought I had this correct (since it actually did reject modes like I expected during testing), Ville Syrjala from Intel pointed out that the logic here isn't correct. max_clock refers to the max symbol rate supported by the encoder, so limiting clock to ds_clock using max() doesn't make sense. Additionally, we want to check against 6bpc for the time being since that's the

The following patchset remove use of the deprecated drmP.h header file in the nouveau driver(s). As preparation a dependency on drm_os_linux.h is dropped. The list of include files are sorted and are in some cases divided up in blocks of linux/* drm/* etc. The removal is divided up in a few patches that was the logical steps to remove the use of drmP.h. Build tested with allmodconfig and
