Subject: [PATCH] drm/nv04: fix null pointer 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....

...a44e499 ("drm/nouveau/disp: introduce proper init/fini, separate from create/destroy") started to call display init routines on pre-nv50 hardware on module load. But LVDS init code sets driver state in a way which prevents modesetting code from operating properly. nv04_display_init calls nv04_dfp_restore, which sets encoder->last_dpms to NV_DPMS_CLEARED. drm_crtc_helper_set_mode nv04_dfp_prepare nv04_lvds_dpms(DRM_MODE_DPMS_OFF) nv04_lvds_dpms checks last_dpms mode (which is NV_DPMS_CLEARED) and wrongly assumes it's a "powersaving mode", the new one (DRM_MODE_DPMS_O...

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).

Hello, I have my work on the nv vpe video decoder in a functional state. In case you didn't know this decoder accelerates mpeg2 video at the idct/mc level. I have verified that it works on nv40 hardware. I believe it works on nv30 hardware (and maybe some earlier hardware), but I cannot verify since I have none. I will reply with patches against the kernel, drm, ddx and mesa for
