Add all the necessary bits to pass v4l2-compliance in stateful decoding mode. Mostly includes tracking the state of the decoder, allowing the OUTPUT queue to stream while the CAPTURE queue is inactive, handling resolution change events, draining with V4L2_DEC_CMD_STOP, copying more metadata from the src buffers to the dst buffers, etc. Signed-off-by:

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. Signed-off-by:

When the request is completed, all controls are copied to the request object. However, when VIDIOC_G_EXT_CTRLS attempts to read control values from the request it will read the current value instead for any control reference that has a NULL ref->req pointer. But that's wrong: after completing the request *all* controls should have a non-NULL ref->req pointer since they are after all copied to the request. So set ref->req if it wasn't set already.

In a recent change to the SPI subsystem [1], a new `delay` struct was added to replace the `delay_usecs`. This change replaces the current `delay_usecs` with `delay` for this driver. The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure that both `delay_usecs` & `delay` are used (in this order to preserve backwards compatibility).

The entity variable was being initialized in the wrong place, before the parameters have been checked. To solve this, completely removed the entity variable and replaced it with the initialization value : &sd->entity. This will avoid dereferencing 'sd' pointer before it's being checked if it's NULL.

A use-after-free bug occures when unbinding the device while it streams. The 'struct vimc_ent_device' allocated for the 'Sensor A' is freed when calling the sensor's 'rm' callback but the freed pointer is later accessed in the function 'vimc_streamer_pipeline_terminate'. To fix this bug, move the release callback of the vimc entities and vimc_device to the release callback of v4l2_device. The .rm callback of vimc_ent_config is replaced by two callbacks: .unregister - this is called upon removing the device and it unregisters the entity. This is an optional callback since subdevices don't need to implement it because they are already unregistered in v4l2_device_unregister. .release - this is called from the release callback of v4l2_device and it frees the entity. This ensures that the entities will be released when the last fh of any of the devices is closed.

In future patch, the release of the device will move to the release callback of v4l2_device. Therefore the device will be released only when the last fh will be closed. Dynamic allocation will then be needed since when the device is unbounded and then bounded again, it might be that the probe callback will run before the release of the last device is finished. In that case both operations will run on the same memory concurrently and cause memory corruption. This patch also removes the pdev field of vimc_device since it is not needed anymore. Signed-off-by:

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. Signed-off-by:

The driver is deprecated and scheduled for removal by the end of 2020. The reason is that this driver is for old and obsolete hardware, and it produces a continuous stream of syzbot errors due to poor code. In order to prevent removal the following actions would have to be taken: - clean up the code - convert to the vb2 framework - fix the disconnect and free-on-last-user handling (i.e., add a release callback for struct v4l2_device and rework the code to use that correctly).

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. This issue was found with the help of Coccinelle.

The address of VSP2_VI6_HGT_LBx_H are VSP2_VI6_HGT_LB0_H : 0x3428 VSP2_VI6_HGT_LB1_H : 0x3430 VSP2_VI6_HGT_LB2_H : 0x3438 VSP2_VI6_HGT_LB3_H : 0x3440 Thus, VI6_HGT_LBn_H() macro should start from 0x3420 instead of 0x3430. This patch fixes it. Fixes: 26e0ca22 ("[media] v4l: Renesas R-Car VSP1 driver") Reported-by:

include/media/i2c/smiapp.h was meant to serve systems where the sensor is enumerated through platform data. That's no longer necessary, hopefully not even in out-of-tree use cases. Move the definitions to the appropriate headers. Signed-off-by:

Combine the two trivial functions reading limits into one. Also rename smiapp_get_all_limits() as smiapp_read_all_smia_limits(). Signed-off-by:

Move SMIA limit reading up, where other limit and capability handling takes place. Signed-off-by:

Instead of direct array access, turn accessing limit information into a function. Going forward, more elaborate CCS limits will replace most SMIA limits, and conversion will be less complicated this way. Signed-off-by:
