It' unused and there's also not really any way to make it work with the current code. So better rip it out. Reviewed-by:

- Tune down yelling RETURNS. - OCD align all the parameters the same. - Add missing kerneldoc, which also means that we need to include the kerneldoc from the drm_modes.h header now. - Add missing Returns: sections. - General polish and clarification - especially the kerneldoc for the mode creation helpers seems to have been some good specimen of copypasta gone wrong. All actual code changes have all been extracted into prep patches since there was simply too much to polish. v2: More polish for the command line modeline functions. Reviewed-by:

Totally unused and actually redundant with maxX for display mode validation. The fb helper otoh needs to check pitch limits, but that is delegated into drivers instead. Reviewed-by:

There's a neat FIXME asking whether this is really need. I'd say really no. Reviewed-by:

I want to also include kerneldoc from the header (for static inline functions and structs), but fishing the right pieces out of a giant header is a real pain. So split things out. Note that it's not a really clean header with sane include orders, but given's drm historical knack for giant headers detangling this is a major task. v2: Also extract struct drm_cmdline_mode.

Makes more sense and gives better grouping in the DocBook function reference sections. To make this possible we need to expose two functions from drm_crtc.c though. To avoid further namespace pollution in the system wide headers create a new internal header for such drm internal symbols. I expect that longer-term we'll add tons more, but since my goal here is to polish the kerneldoc that's for another day. Reviewed-by:

There's not really any value in stating that no locking is needed. And even if the comment is useful, a check for the right mutex at the beginning of the function is better since that can't be ingored as easily as a bit of documentation. Note that drm_mode_probed_add in drm_crtc.c is also changed, the next patch will move this into drm_modes.c v2: Don't add locking WARN_ONs where it is not strictly required (i.e. the two functions to validate/prune mode lists).

And clean it up so that there's no kerneldoc warnings. There's still a lot to do with this one here. Reviewed-by:

It's only used by imx, and that one gets it wrong - there's no need to deteach the encoder before removing it. And really, neither current drm modesetting code nor all the userspace we have can handle dynamic changes in the set of possible encoders for a given connector. So let's just remove this before someone starts doing something really nasty with it. As a plus, one less kerneldoc comment to write.

While at it do a tiny bit of interface cleanup and convert boolean return values to bool. With this patch all exported functions and inline helpers which are part of the drm_mm public interface are documented. Also drop superflous extern function modifiers since most of drm_mm.h doesn't use them - more consistent that way. Reviewed-by:

kerneldoc polish will follow in the next patch. Hopefully documenting the lru scan support a bit better spurs someone to give this a shot in the ttm eviction code. At least in i915 it helped quite a lot with memory thrashing on platforms where eviction was (we've fixed that too meanwhile) fairly expensive. Reviewed-by:

I've done quite a bit of cleanups, clarifications and mostly integrating kerneldoc. So I guess I should add myself. Also split up the copyright notices per holder to make it clear which year ranges are covered. Reviewed-by:

For giant hilarity the DocBook reference overview is only generated when in a level 2 section, not in a level 3 section. So we need to move this up a bit as a side-by-side section to the main PRIME documentation. Whatever. To have a complete set of references add the missing kerneldoc for all functions exported to modules with the exception of the file private init/destroy functions - drivers have no business calling those, so let's just drop the EXPORT_SYMBOL instead. Also reflow the function parameters to align correctly and break at 80 chars - my OCD couldn't stand them while writing the kerneldoc ;-) Reviewed-by:

PRIME fds aren't actually GEM fds but are (like the modeset API) independent of the underlying buffer manager, as long as that one uses uint32_t as handles. So move that entire section out of the GEM section and reword it a bit to clarify which parts of PRIME are generic, and which are the mandatory pieces for GEM drivers to correctly implement the GEM lifetime rules. The rewording mostly consists of not mixing up GEM, PRIME and DRM. I've considered adding some blurbs to the GEM object lifetime section about interactions with dma-bufs, but then dropped that. As long as drivers use the right helpers they should have this all implemented correctly and hence can be regarded as an implementation detail of the PRIME/GEM helpers. So no need to confuse driver writers with those tricky interactions. Reviewed-by:

Thierry created such nice kerneldocs, it's a shame we've left them lingering! For the fun of it also add a bit of kerneldoc to the header so that we can also include that. Just in case someone adds kerneldoc in there. Cc: Thierry Reding <thierry.reding@gmail.com> Reviewed-by:

By consolidating them all into one section at the very end. And to make double-sure that no one gets confused start with a stern warning against any use of them. And prefix all subsections with "Legacy". Reviewed-by:

- This is _not_ a generic interface to create gem objects, but just an interface to make early boot services (like boot splash) with a generic KMS userspace driver possible. Hence it's better to move the documentation for this from the GEM section to the KMS section, next to the creation of framebuffer objects. - Make it really clear that the returned handle isn't necessarily a GEM object (it can also be e.g. a TTM handle when running on top of vmwgfx). - Add a paragraph to make it clear that this is just for unaccelarated userspace - gpu drivers need to have their own buffer object creation ioctl which is hardware specific. v2: Clarify that the documentation doesn't just apply to GEM-based drivers only but is now generally valid, as suggested by David. v3: Polish the intro sentence a bit and one s/objects/handles/ for clarification, both suggested by Laurent. v4: More text polish from Laurent's review. v5: More typo fixes from Dieter.
