* media: v4l2-fwnode: add initial connector parsing supportMarco Felsch2020-03-121-0/+82
| | | | | | | | | | | | The patch adds the initial connector parsing code, so we can move from a driver specific parsing code to a generic one. Currently only the generic fields and the analog-connector specific fields are parsed. Parsing the other connector specific fields can be added by a simple callbacks.

* media: v4l2-fwnode: add v4l2_fwnode_connectorMarco Felsch2020-03-121-0/+57
| | | | | | | | | | | | | | | | | | Currently every driver needs to parse the connector endpoints by it self. This is the initial work to make this generic. A generic connector has common members and connector specific members. The common members are: - type - label (optional) - links - nr_of_links The specific members are stored within a union, since only one of them can be available at the time. Since this is the initial support the patch adds only the analog-connector specific ones.

* media: rc: make scancodes 64 bitSean Young2020-03-122-6/+6
| | | | | | | | | | | | | There are many protocols that encode more than 32 bit. We want 64 bit support so that BPF IR decoders can decode more than 32 bit. None of the existing kernel IR decoders/encoders support 64 bit, for now. The MSC_SCAN event can only contain 32 bit scancodes, so we only generate MSC_SCAN events if the scancode fits into 32 bits. The full 64 bit scancode can be read from the lirc chardev. Signed-off-by: Sean Young <sean@mess.org> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
* media: v4l2-mem2mem: handle draining, stopped and next-buf-is-last statesNeil Armstrong2020-03-051-0/+133
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the draining and stop phase of the HW decoder mem2mem bahaviour is now clearly defined, we can move handling of the following states to the common v4l2-mem2mem core code: - draining - stopped - next-buf-is-last By introducing the following v4l2-mem2mem APIs: - v4l2_m2m_encoder_cmd/v4l2_m2m_ioctl_encoder_cmd to handle start/stop command - v4l2_m2m_decoder_cmd/v4l2_m2m_ioctl_decoder_cmd to handle start/stop command - v4l2_m2m_update_start_streaming_state to update state on start of streaming of the de/encoder queue - v4l2_m2m_update_stop_streaming_state to update state on stop of streaming of the de/encoder queue - v4l2_m2m_last_buffer_done to make the current dest buffer as the last one And inline helpers: - v4l2_m2m_mark_stopped to mark the de/encoding process as stopped - v4l2_m2m_clear_state to clear the de/encoding state - v4l2_m2m_dst_buf_is_last to detect the current dequeued dst_buf is the last - v4l2_m2m_has_stopped to detect the de/encoding stopped state - v4l2_m2m_is_last_draining_src_buf to detect the current source buffer should be the last processing before stopping the de/encoding process The special next-buf-is-last when min_buffers != 1 case is also handled in v4l2_m2m_qbuf() by reusing the other introduced APIs. This state management has been stolen from the vicodec implementation, and is no-op for drivers not calling the v4l2_m2m_encoder_cmd or v4l2_m2m_decoder_cmd and v4l2_m2m_update_start/stop_streaming_state. The vicodec will be the first one to be converted as an example.

* media: Split v4l2_pipeline_pm_use into v4l2_pipeline_pm_{get, put}Ezequiel Garcia2020-03-021-15/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, v4l2_pipeline_pm_use() prototype is: int v4l2_pipeline_pm_use(struct media_entity *entity, int use) Where the 'use' argument shall only be set to '1' for enable/power-on, or to '0' for disable/power-off. The integer return is specified as only meaningful when 'use' is set to '1'. Let's enforce this semantic by splitting the function in two: v4l2_pipeline_pm_get and v4l2_pipeline_pm_put. This is done for several reasons. It makes the API easier to use (or harder to misuse). It removes the constraint on the values the 'use' argument shall take. Also, it removes the need to constraint the return value, by making v4l2_pipeline_pm_put void return. And last, it's more consistent with other kernel APIs, such as the runtime pm APIs, which makes the code more symmetric.

* media: v4l2-core: fix v4l2_buffer handling for time64 ABIArnd Bergmann2020-01-031-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | The v4l2_buffer structure contains a 'struct timeval' member that is defined by the user space C library, creating an ABI incompatibility when that gets updated to a 64-bit time_t. As in v4l2_event, handle this with a special case in video_put_user() and video_get_user() to replace the memcpy there. Since the structure also contains a pointer, there are now two native versions (on 32-bit systems) as well as two compat versions (on 64-bit systems), which unfortunately complicates the compat handler quite a bit. Duplicating the existing handlers for the new types is a safe conversion for now, but unfortunately this may turn into a maintenance burden later. A larger-scale rework of the compat code might be a better alternative, but is out of scope of the y2038 work. Sparc64 needs a special case because of their special suseconds_t definition.

While passing a 32-bit time_t here would be sufficient for CLOCK_MONOTONIC timestamps, simply redefining the structure to use the kernel's __kernel_old_timespec would not work for any library that uses a copy of the linux/videodev2.h header file rather than including the copy from the latest kernel headers. This means the kernel has to be changed to handle both versions of the structure layout on a 32-bit architecture. The easiest way to do this is during the copy from/to user space.

* media: v4l2-device.h: Explicitly compare grp{id,mask} to zero in v4l2_device ↵Nathan Chancellor2019-12-161-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | macros When building with Clang + -Wtautological-constant-compare, several of the ivtv and cx18 drivers warn along the lines of: drivers/media/pci/cx18/cx18-driver.c:1005:21: warning: converting the result of '<<' to a boolean always evaluates to true [-Wtautological-constant-compare] cx18_call_hw(cx, CX18_HW_GPIO_RESET_CTRL, ^ drivers/media/pci/cx18/cx18-cards.h:18:37: note: expanded from macro 'CX18_HW_GPIO_RESET_CTRL' #define CX18_HW_GPIO_RESET_CTRL (1 << 6) ^ 1 warning generated. This warning happens because the shift operation is implicitly converted to a boolean in v4l2_device_mask_call_all before being negated. This can be solved by just comparing the mask result to 0 explicitly so that there is no boolean conversion. The ultimate goal is to enable -Wtautological-compare globally because there are several subwarnings that would be helpful to have. For visual consistency and avoidance of these warnings in the future, all of the implicitly boolean conversions in the v4l2_device macros are converted to explicit ones as well.

| * cec: add cec_adapter to cec_notifier_cec_adap_unregister()Hans Verkuil2019-10-071-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible for one HDMI connector to have multiple CEC adapters. The typical real-world scenario is that where one adapter is used when the device is in standby, and one that's better/smarter when the device is powered up. The cec-notifier changes were made with that in mind, but I missed that in order to support this you need to tell cec_notifier_cec_adap_unregister() which adapter you are unregistering from the notifier. Add this additional argument. It is currently unused, but once all drivers use this, the CEC core will be adapted for these use-cases.

* | media: v4l: Add definitions for HEVC stateless decodingPaul Kocialkowski2019-10-242-0/+219
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces the required definitions for HEVC decoding support with stateless VPUs. The controls associated to the HEVC slice format provide the required meta-data for decoding slices extracted from the bitstream. They are not exported to the public V4L2 API since reworking this API will likely be needed for covering various use-cases and new hardware. Multi-slice decoding is exposed as a valid decoding mode to match current H.264 support but it is not yet implemented. The interface comes with the following limitations: * No custom quantization matrices (scaling lists); * Support for a single temporal layer only; * No slice entry point offsets support; * No conformance window support; * No VUI parameters support; * No support for SPS extensions: range, multilayer, 3d, scc, 4 bits; * No support for PPS extensions: range, multilayer, 3d, scc, 4 bits.

Add v4l2_m2m_buf_done_and_job_finish() to correctly return source and destination buffers and mark the job as finished while taking a held destination buffer into account (i.e. that buffer won't be returned). This has to be done while job_spinlock is held to avoid race conditions. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is often useful to figure out if a pixel_format is either YUV or RGB especially for driver who can perform the pixel encoding conversion. Instead of having each driver implement its own "is_this_yuv/rgb" function based on a restricted set of pixel value, it is better to do this in centralized manner. We therefore add a pixel_enc member to the v4l2_format_info structure to quickly identify the related pixel encoding. And add helper functions to check pixel encoding.
