* drm/doc: Consistent kerneldoc include orderDaniel Vetter2017-03-141-12/+12
| | | | | | | | | | | | | | First overview text (if there is any), then headers (since generally you want to start out with the data structures), then all the other stuff with functions. Most of this is pre-shpinx, since with the old docbook only the overview stuff was pulled in directly. Everything else was put in a per-section index, so include order didn't really matter.

* drm: Introduce drm_gem_object_{get,put}()Thierry Reding2017-02-281-8/+6
| | | | | | | | | | | | | | | | | | For consistency with other reference counting APIs in the kernel, add drm_gem_object_get() and drm_gem_object_put(), as well as an unlocked variant of the latter, to reference count GEM buffer objects. Compatibility aliases are added to keep existing code working. To help speed up the transition, all the instances of the old functions in the DRM core are already replaced in this commit. The existing semantic patch for the DRM subsystem-wide conversion is extended to account for these new helpers.

* Documentation/gpu: drm-mm.rst: fix formatting for struct vm_operations_structLiviu Dudau2017-01-311-4/+11
| | | | | | | | | | | | drm-mm.rst contains some unformatted dump of the vm_operations_struct structure. Add some C formatting around it and some context for the dump. While there, update the structure to resemble the new signature for the fault handler after commit 25d3db7600b8 (mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmf).

* drm: Document drm_cache interfaceGabriel Krisman Bertazi2017-01-101-0/+6
| | | | | | | | | | | | | | | | | Notice that this uncovers an issue with the kernel-doc handling of array arguments, causing the first parameter of drm_clflush_pages() to not show up in the rst-generated page. A proposed fix is under review in linux-doc: <http://www.spinics.net/lists/linux-doc/msg42544.html> Changes since v1: - Add section to drm-mm.rst. - Fix kernel-doc style issues. - s/memory/kernel memory/.

* drm: allow to use mmuless SoCBenjamin Gaignard2017-01-061-0/+11
| | | | | | | | | | | | | | | | | | Some SoC without MMU have display driver where a drm/kms driver could be implemented. Before doing such kind of thing drm/kms must allow to use mmuless devices. This patch propose to remove MMU configuration flag and add a cma helper function to help implementing mmuless display driver version 4: - add documentation about drm_gem_cma_get_unmapped_area() - stub it MMU case Signed-off-by: Benjamin Gaignard <benjamin.gaignard@linaro.org> [danvet: Use recommended struct member references in kernel-doc.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1483521177-21794-4-git-send-email-benjamin.gaignard@linaro.org
* drm/mm: Some doc polishDaniel Vetter2016-12-301-1/+1
| | | | | | | | | | | | | | | | | | | Added some boilerplate for the structs, documented members where they are relevant and plenty of markup for hyperlinks all over. And a few small wording polish. Note that the intro needs some more love after the DRM_MM_INSERT_* patch from Chris has landed. v2: Spelling fixes (Chris). v3: Use &struct foo instead of &foo structure (Chris).

* drm/doc: Reorg drm-mm.rstDaniel Vetter2016-08-161-29/+29
| | | | | | | | | | | | | | - Readjust headings - we lost one level through the extraction into a separate .rst file. - Merge helper reference sections with the helper documentation - that split was just an artifact of the docbook toolchain sucking at too deep nesting levels. No such problems with sphinx. - Move the cma helpers in with the gem documentation, since they're helpers to implement gem using CMA/dma memory as a backend.
