The latest versions of Google camera and codec HAL depends on such feature. At this stage, it supports only stateless codecs. It has been discussed for a long time (at least over the last 3-4 years), and we finally reached to something that seem to work. This series contain both the API and core changes required to support it and a new m2m decoder driver (cedrus). As the current API is still experimental, the only real driver using it (cedrus) was added at staging[1]. We intend to keep it there for a while, in order to test the API. Only when we're sure that this API works for other cases (like encoders), we'll move this driver out of staging and set the API into a stone. [1] We added support for the vivid virtual driver (used only for testing) to it too, as it makes easier to test the API for the ones that don't have the cedrus hardware" * tag 'media/v4.20-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (53 commits) media: dt-bindings: Document the Rockchip VPU bindings media: platform: Add Cedrus VPU decoder driver media: dt-bindings: media: Document bindings for the Cedrus VPU driver media: v4l: Add definition for the Sunxi tiled NV12 format media: v4l: Add definitions for MPEG-2 slice format and metadata media: videobuf2-core: Rework and rename helper for request buffer count media: v4l2-ctrls.c: initialize an error return code with zero media: v4l2-compat-ioctl32.c: add missing documentation for a field media: media-request: update documentation media: media-request: EPERM -> EACCES/EBUSY media: v4l2-ctrls: improve media_request_(un)lock_for_update media: v4l2-ctrls: use media_request_(un)lock_for_access media: media-request: add media_request_(un)lock_for_access media: vb2: set reqbufs/create_bufs capabilities media: videodev2.h: add new capabilities for buffer types media: buffer.rst: only set V4L2_BUF_FLAG_REQUEST_FD for QBUF media: v4l2-ctrls: return -EACCES if request wasn't completed media: media-request: return -EINVAL for invalid request_fds media: vivid: add request support media: vivid: add mc ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a 'bool from_other_dev' argument: set to true if the two handlers refer to different devices (e.g. it is true when inheriting controls from a subdev into a main v4l2 bridge driver). This will be used later when implementing support for the request API since we need to skip such controls.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Consumer devices are provided with a wide different range of types supported by the same driver, allowing different configutations. In order to make easier to setup media controller links, "taint" pads with the signal type it carries. While here, get rid of DEMOD_PAD_VBI_OUT, as the signal it carries is actually the same as the normal video output. The difference happens at the video/VBI interface: - for VBI, only the hidden lines are streamed; - for video, the stream is usually cropped to hide the vbi lines.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As pointed by Daniel Scheller <d.scheller@gmx.net>, sparse warns that a segment may fall through. We're deprecating this warning in favor of gcc 8 equivalent warning. In this specific case, the code for DVB-S applies for DVB-S2. In a matter of fact, several things there (like rolloff factor logic) assume that the transponder is DVB-S2. So, add the corresponding fall-trough markup, for gcc to properly ignore it.

* treewide: kzalloc() -> kcalloc()Kees Cook2018-06-123-6/+6

This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

* media: dvb-frontends/stv0910: make TS speed configurableDaniel Scheller2018-05-282-3/+3
| | | | | | | | | | | | | | | Add a tsspeed config option to struct stv0910_cfg which can be used by users of the driver to set the (parallel) TS speed (higher speeds enable support for higher bitrate transponders). If tsspeed isn't set in the config, it'll default to a sane value. This commit also updates the two consumers of the stv0910 driver (ngene and ddbridge) to have a default tsspeed in their stv0910_cfg templates.
