| * | drm/doc: Clarify PRIME documentationDaniel Vetter2014-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NV16M description contained some copy-and-paste text from NV12M, suggesting that this format is a 4:2:0 format when it really is a 4:2:2 format. Fixed the text. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
| * | [media] v4l: Document timestamp buffer flag behaviourSakari Ailus2014-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Timestamp buffer flags are constant at the moment. Document them so that 1) they're always valid and 2) not changed by the drivers. This leaves room to extend the functionality later on if needed.

| * | [media] v4l: Add timestamp source flags, mask and document themSakari Ailus2014-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some devices do not produce timestamps that correspond to the end of the frame. The user space should be informed on the matter. This patch achieves that by adding buffer flags (and a mask) for timestamp sources since more possible timestamping points are expected than just two. A three-bit mask is defined (V4L2_BUF_FLAG_TSTAMP_SRC_MASK) and two of the eight possible values is are defined V4L2_BUF_FLAG_TSTAMP_SRC_EOF for end of frame (value zero) V4L2_BUF_FLAG_TSTAMP_SRC_SOE for start of exposure (next value).

| * | [media] v4l: Use full 32 bits for buffer flagsSakari Ailus2014-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The buffer flags field is 32 bits but the defined only used 16. This is fine, but as more than 16 bits will be used in the very near future, define them as 32-bit numbers for consistency.

| * | [media] v4l: Document timestamp behaviour to correspond to realitySakari Ailus2014-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Document that monotonic timestamps are taken after the corresponding frame has been received, not when the reception has begun. This corresponds to the reality of current drivers: the timestamp is naturally taken when the hardware triggers an interrupt to tell the driver to handle the received frame. Remove the note on timestamp accuracy as it is fairly subjective what is actually an unstable timestamp. Also remove explanation that output buffer timestamps can be used to delay outputting a frame. Remove the footnote saying we always use realtime clock.

Fortunately, the original commit is good enough to serve as the basis for documenting it. Also, the support for it is done by dmxdev implementation. So, add a proper documentation for it, based on the description of the original changeset. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
