...ointer dereferences of native_mode nv_connector->native_mode is not set when no modes were found for the connector, so its existence can't be assumed. In nv04_dfp_mode_fixup, reject the mode if GPU scaling is enabled but native mode is not known. In nv04_dfp_mode_set, use clock value from nv_encoder->mode instead of nv_connector->native_mode. If panel scaling is enabled on a TMDS display and the display did not have a valid EDID, native_mode is NULL. In nv04_lvds_dpms and nv04_dfp_restore, refuse to turn on an LVDS panel if native mode is not known. While clock is not always required...

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. Karol Herbst (6): kms/nv50: move nv50_mstm out of the dp union in nouveau_encoder kms/nv50: reject interlaced modes if the hardware

The patches contain some tidy-up work, and refactoring that has arisen as a by-product of my initial work on adding TV support to nv50. Joel Holdsworth (4): drm/nouveau: Removed unneeded include in nvc0_fence.c drm/nouveau: Replaced magic numbers with defines from nouveau_reg drm/nouveau: Replaced copy-pasted nv_wait with nv50_wait_dpms_ctrl helper drm/nouveau: Refactored encoder

To start off: this patch series is less work to review then it looks - most (but not all) of the nouveau related work has already been reviewed elsewhere. 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

It seems it was only locking up in the context of nouveau_hw_save_vga_fonts, when it actually did something (because the console wasn't already in graphics mode).
