...DP port. This comes out to 35 different encoders. Unfortunately, this can't really be optimized to make less encoders either. So, what if we bumped the limit to 64? Unfortunately this has one very awkward drawback: we already expose 32-bit bitmasks for encoders to userspace in drm_encoder->possible_clones. Yikes. While cloning is still (rarely) used in certain modern video hardware, it's mostly used in situations where memory bandwidth is so limited that it's not possible to scan out from 2 CRTCs at once. So, let's try to compromise here: allow encoders with indexes <32 to have non...

Unfortunately this has one very awkward drawback: we already expose 32-bit bitmasks for encoders to userspace in drm_encoder->possible_clones. Yikes. Luckily for us however, the year is 2019 and modern hardware that supports cloning is basically non-existent. So, let's try to compromise here: allow encoders with indexes <32 to have non-zero values in drm_encoder->possible_clones, and don't allow encoders with higher inde...

...c in the i'th slot of the x-screens xf86CrtcConfig anymore, once ZaphodHeads has only selected a subset of all crtcs of a graphics card for a given x-screen, instead of all crtcs. This breaks the mapping of bit positions in the bit masks returned in kencoder->possible_crtcs and kencoder->possible_clones. A 1 bit in position i of those masks allows use of the kernels i'th crtc for the given kencoder. The X-Servers dix code checks those bit masks for valid xf86Output -> xf86Crtc assignments, assuming that the i'th slot xf86CrtcConfigPtr config->crtc[i] corresponds to bit i in the xf8...

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

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

Hi all, First thing first: It works, I now no longer have a few dropped frames every 10s on my testbox here with the pageflip i-g-t tests. Random notes: - New design has per-crtc locks to protect the crtc input-side (pageflip, cursor) for r/w and the output state of the crtc (mode, dpms) as read-only. It also required completely revamped fb lifecycle management, those are now refcounted
