In nv17_tv_get_ld_modes(), the return value of drm_mode_duplicate() is assigned to mode, which will lead to a NULL pointer dereference on failure of drm_mode_duplicate(). Add a check to avoid npd.

In nv17_tv_get_hd_modes(), the return value of drm_mode_duplicate() is assigned to mode, which will lead to a NULL pointer dereference on failure of drm_mode_duplicate(). The same applies to drm_cvt_mode(). Add a check to avoid null pointer dereference. Signed-off-by: Ma Ke <make_ruc2021 at 163.com> --- drivers/gpu/drm/nouveau/dispnv04/tvnv17.c | 4 +...

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

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).

This patch series adds TV-out modesetting support to the KMS implementation. I've tried to test it on all the hardware I've got at hand (that is nv11, nv17, nv34, nv35, nv40, nv4b) with every possible output combination; I believe it has reached a mergeable state, however it depends on some commits from drm-next that haven't got into Linus' tree yet, if you agree to merge this

A call to drm_simple_encoder_init() initializes an encoder without further functionality. It only provides the destroy callback to cleanup the encoder's state. Only few drivers implement more sophisticated encoders than that. Most drivers implement such a simple encoder and can use drm_simple_encoder_init() instead. The patchset converts drivers where the encoder's instance is embedded in
