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 ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Set the capabilities field of v4l2_requestbuffers and v4l2_create_buffers. The various mapping modes were easy, but for signaling the request capability a new 'supports_requests' bitfield was added to videobuf2-core.h (and set in vim2m and vivid). Drivers have to set this bitfield for any queue where requests are supported.

| * | media: isif: fix a NULL pointer dereference bugWenwen Wang2018-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In isif_probe(), there is a while loop to get the ISIF base address and linearization table0 and table1 address. In the loop body, the function platform_get_resource() is called to get the resource. If platform_get_resource() returns NULL, the loop is terminated and the execution goes to 'fail_nobase_res'. Suppose the loop is terminated at the first iteration because platform_get_resource() returns NULL and the execution goes to 'fail_nobase_res'. Given that there is another while loop at 'fail_nobase_res' and i equals to 0, one iteration of the second while loop will be executed. However, the second while loop does not check the return value of platform_get_resource(). This can cause a NULL pointer dereference bug if the return value is a NULL pointer. This patch avoids the above issue by adding a check in the second while loop after the call to platform_get_resource().

These drivers also must now call v4l2_async_notifier_init() before adding asd's to their notifiers. There may still be cases where a platform driver maintains a list of asd's that is a duplicate of the notifier asd_list, in which case its possible the platform driver list can be removed, and can reference the notifier asd_list instead. One example of where a duplicate list has been removed in this patch is xilinx-vipp.c. If there are such cases remaining, those drivers should be optimized to remove the duplicate platform driver asd lists. None of the changes to the platform drivers in this patch have been tested. Verify that the async subdevices needed by the platform are bound at load time, and that the driver unloads and reloads correctly with no memory leaking of asd objects.

As a result the notifier->subdevs array is no longer allocated or re-allocated, and by extension the max_subdevs value is also no longer needed. Callers of the fwnode endpoint and reference parsing functions must now first initialize the notifier with a call to v4l2_async_notifier_init(). This includes the function v4l2_async_register_subdev_sensor_common(), and the intel-ipu3, omap3isp, and rcar-vin drivers. Since the notifier->subdevs array is no longer allocated in the fwnode endpoint and reference parsing functions, the callers of those functions must never reference that array, since it is now NULL. Of the drivers that make use of the fwnode/ref parsing, only the intel-ipu3 driver references the ->subdevs[] array, (in the notifier completion callback), so that driver has been modified to iterate through the notifier->asd_list instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On a decoder instance, after the profile has been parsed from the stream __v4l2_ctrl_s_ctrl() is called to notify userspace about changes in the read-only profile control. This ends up calling back into the CODA driver where a missing check on the s_ctrl caused the profile information that has just been parsed from the stream to be overwritten with the default baseline profile. Later on the driver fails to enable frame reordering, based on the wrong profile information.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several CEC functions are actually specific for use with receivers, i.e. they should be part of the V4L2 subsystem, not CEC. These functions deal with validating and modifying EDIDs for (HDMI) receivers, and they do not actually have anything to do with the CEC subsystem and whether or not CEC is enabled. The problem was that if the CEC_CORE config option was not set, then these functions would become stubs, but that's not right: they should always be valid. So replace the cec_ prefix by v4l2_ and move them to v4l2-dv-timings.c. Update all drivers that call these accordingly.
