Always set pps_cb_qp_offset and pps_cr_qp_offset values in Hantro/G2 register whatever is V4L2_HEVC_PPS_FLAG_PPS_SLICE_CHROMA_QP_OFFSETS_PRESENT flag value. The vendor code does the same to set these values. This fixes conformance test CAINIT_G_SHARP_3. Fluster HEVC score is increase by one with this patch. Signed-off-by:

PoC shall be int the range of -2^31 to 2^31 -1 (HEVC spec section 8.3.1 Decoding process for picture order count). The current way to know if an entry in reference picture array is free is to test if PoC = UNUSED_REF. Since UNUSED_REF is defined as '-1' that could lead to decode issue if one PoC also equal '-1'. PoC with value = '-1' exists in conformance test SLIST_B_Sony_9. Change the way unused entries are managed in reference pictures array to avoid using PoC to detect then. This patch doesn't change fluster HEVC score. Signed-off-by:

Use pps->column_width_minus1[j] + 1 as value for the tile info buffer instead of pps->column_width_minus1[j + 1]. The patch fixes DBLK_E_VIXS_2, DBLK_F_VIXS_2, DBLK_G_VIXS_2, SAO_B_MediaTek_5, TILES_A_Cisco_2 and TILES_B_Cisco_1 tests in fluster.

Hantro decoder doesn't take care of the requested and aligned size of the capture buffer. Stop using the bitstream width/height and use capture frame size stored in the context to get the correct values. hantro_hevc_chroma_offset() and hantro_hevc_motion_vectors_offset() are only used in hantro_g2_hevc_dec.c so take the opportunity to move them here. fluster HEVC score goes up from 77 to 85 successful tests (over 147) with this patch.

Hantro G2 post processor is able to down scale decoded frames by a factor of 2, 4 or 8. Add enum_framesizes() ops to postproc_ops structure to enumerate the possible output sizes for a given input resolution. For G2 post-processor use fsize->index (from 0 to 3) as power of 2 divisor. As described in v4l2 documentation return -EINVAL when scaling down isn't possible. fluster scores: 77/147 for HEVC 143/303 for VP9 Signed-off-by:

The AWB workqueue runs in a kernel thread and needs to be synchronized w.r.t. the streaming status. It is possible that streaming is stopped while the AWB workq is running. In this case it is likely that the check for vb2_start_streaming_called is done at one point in time, but the AWB computations are done later, including a call to isc_update_profile, which requires streaming to be started. Thus , isc_update_profile will fail if during this operation sequence the streaming was stopped. To solve this issue, a mutex is added, that will serialize the awb work and streaming stopping, with the mention that either streaming is stopped completely including termination of the last frame is done, and after that the AWB work can check stream status and stop; either first AWB work is completed and after that the streaming can stop correctly. The awb spin lock cannot be used since this spinlock is taken in the same context and using it in the stop streaming will result in a recursion BUG. Signed-off-by:

While this does not happen in production, this check should be done versus the mask, as checking with the YCYC value may not include some bits that may be set. It is correct and safe to check the whole mask. Fixes: 123aaf81 ("media: atmel: atmel-sama5d2-isc: fix YUYV format") Signed-off-by:

During experiments with libcamera, it looks like vb2_is_streaming returns true before our start streaming is called. Order of operations is streamon -> queue -> start_streaming ISC would have started the DMA immediately when a buffer is being added to the vbqueue if the queue is streaming. It is more safe to start the DMA after the start streaming of the driver is called. Thus, even if vb2queue is streaming, add the buffer to the dma queue of the driver instead of actually starting the DMA process, if the start streaming has not been called yet. Tho achieve this, we have to use vb2_start_streaming_called instead of vb2_is_streaming. Signed-off-by:

The vertical subsampling factor is currently not considered in the offset calculation for plane cropping done in rpf_configure_partition. This causes a distortion (shift of the color plane) when formats with the vsub factor larger than 1 are used (e.g. NV12, see vsp1_video_formats in vsp1_pipe.c). This commit considers vsub factor for all planes except plane 0 (luminance). Drop generalization of the offset calculation to reduce the binary size.

Use the vb2_fop_release() helper to replace the open-coded version. The video->lock is assigned to the queue lock, used by vb2_fop_release(), so the only functional difference is that v4l2_fh_release() is now called before vsp1_device_put(). This should be harmless. Signed-off-by:

vb2 queue ownership is managed by the ioctl handler helpers (vb2_ioctl_*). There are however use cases where drivers can benefit from checking queue ownership, for instance when open-coding an ioctl handler that needs to perform additional checks before calling the corresponding vb2 operation. Expose the vb2_queue_is_busy() function in the videobuf2-v4l2.h header, and change its first argument to a struct vb2_queue pointer as the function name implies it operates on a queue, not a video_device.
