      media: staging: rkisp1: rsz: remove redundant if statement and add inline doc · 21e4cdcb
      Dafna Hirschfeld authored
      The statement "if (rsz->fmt_type == V4L2_PIXEL_ENC_YUV)"
      can be removed since the value of rsz->fmt_type is either
      V4L2_PIXEL_ENC_YUV or V4L2_PIXEL_ENC_BAYER and the function
      returns if it is bayer. In addition some doc with clarification
      is added.

      media: staging: rkisp1: rsz: get the capture format info from the capture struct · e9ebce2d
      Dafna Hirschfeld authored
      Currently the format info of the capture is retrieved by calling
      the function v4l2_format_info. This is not needed since it is
      already saved in the capture object.

      media: staging: ipu3-imgu: Add a sanity check for the parameter struct size · 839efdb6
      Sakari Ailus authored
      There have been cases where seemingly innocuous patches have broken the
      uAPI by changing the memory layout of the parameter struct. Generally such
      changes also introduce a change in the size of the entire struct. This
      patch adds a sanity check to avoid such cases happening in the future.

      media: staging: ipu3-imgu: Move alignment attribute to field · 8c038eff
      Sakari Ailus authored
      Move the alignment attribute of struct ipu3_uapi_awb_fr_config_s to the
      field in struct ipu3_uapi_4a_config, the other location where the struct
      is used.

      media: staging: ipu3: Fix stale list entries on parameter queue failure · 735a02f1
      Tomasz Figa authored
      When queuing parameters fails, current code bails out without deleting
      the corresponding vb2 buffer from the driver buffer list, but the buffer
      is returned to vb2. This leads to stale list entries and a crash when
      the driver stops streaming:

      media: venus: Mark last capture buffer · 85872f86
      Stanimir Varbanov authored
      According to stateful Codec API the decoder will process all
      remaining buffers from before the source change event in
      dynamic-resolution-change state and mark the last buffer with
      V4L2_BUF_FLAG_LAST.
      
      In Venus case the firmware doesn't mark that last buffer and
      some mechanism have to be created in v4l decoder driver.
      Fortunately the firmware interface (HFI) claims that the
      decoder output buffers will be returned to v4l decoder
      driver before it send the insufficient event.
      
      In order to do that we save last queued in the driver capture
      buffer in the event_notify and issue flush on output firmware
      buffers queue. Once the saved buffer is returned (as a result of
      flush command) we mark it as LAST. For all that possible we
      extend HFI flush command with one more argument and one more
      flush_done HFI driver callback.

      Stanimir Varbanov authored
      Presently the list initialization is done only in
      dynamic-resolution-change state, which leads to list corruptions
      and use-after-free. Init list_head unconditionally in
      vdec_stop_capture called by vb2 stop_streaming without takeing
      into account current codec state.

      media: venus: vdec: Mark flushed buffers with error state · 51df3c81
      Stanimir Varbanov authored
      Once the hfi_session_flush is issued by the vdec all queued
      buffers to firmware should be returned to the v4l driver. Some
      of those buffers are not processed at the time of flush command,
      those buffers has filled len zero (no data). Catch that in
      buffer_done callback and mark not filled capture buffers with
      error state so that client can discard them.

      media: venus: helpers: Done buffers per queue type · 0febf923
      Stanimir Varbanov authored
      Currently calling venus_helper_buffers_done() will return buffers to
      user for both capture and output queues in the same call. This is
      wrong because both queues are really separate and calling
      stop_streaming on one queue shouldn't return buffers for the other.
      Solve this by add a new queue type argument and fix the clients of
      the helper function.

      Stanimir Varbanov authored
      The hfi_destroy function is called too early in remove method. It
      destroys a mutex which is used later in the .remove from pmruntime.
      Solve the issue by moving hfi_destroy after last usage of the mutex.
