media: imx-jpeg: notify source chagne event when the first picture parsed

2023-10-13T09:33:22+00:00

After gstreamer rework the dynamic resolution change handling, gstreamer stop doing capture buffer allocation based on guesses and wait for the source change event when available. It requires driver always notify source change event in the initialization, even if the size parsed is equal to the size set on capture queue. otherwise, the pipeline will be stalled. Currently driver may not notify source change event if the parsed format and size are equal to those previously established, but it may stall the gstreamer pipeline.

media: imx-jpeg: initiate a drain of the capture queue in dynamic resolution change

2023-09-27T07:39:55+00:00

The last buffer from before the change must be marked, with the V4L2_BUF_FLAG_LAST flag, similarly to the Drain sequence above. Meanwhile if V4L2_DEC_CMD_STOP is sent before the source change triggered, we need to restore the is_draing flag after the draining in dynamic resolution change.

The commit in Fixes has removed an fwnode_graph_get_endpoint_by_id() call in mipi_csis_subdev_init(). So the reference that was taken should not be released anymore in the error handling path of the probe and in the remove function. Remove the now incorrect fwnode_handle_put() calls.

Pull media updates from Mauro Carvalho Chehab: - new i2c drivers: ds90ub913, ds90ub953, ds90ub960, dw9719, ds90ub913 - new Intel IVSC MEI drivers - some Mediatek platform drivers were moved to a common location - Intel atomisp2 driver is now working with the main ov2680 driver. Due to that, the atomisp2 ov2680 staging one was removed - the bttv driver was finally converted to videobuf2 framework. This was the last one upstream using videobuf version 1 core. We'll likely remove the old videobuf framework on 6.7 - lots of improvements at atomisp driver: it now works with normal I2C sensors. Several compile-mode dependecies to select between ISP2400 and ISP2401 are now solved in runtime - a new ipu-bridge logic was added to work with IVSC MEI drivers - venus driver gained better support for new VPU versions - the v4l core async framework has gained lots of improvements and cleanups - lots of other cleanups, improvements and driver fixes * tag 'media/v6.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (358 commits) media: ivsc: Add ACPI dependency media: bttv: convert to vb2 media: bttv: use audio defaults for winfast2000 media: bttv: refactor bttv_set_dma() media: bttv: move vbi_skip/vbi_count out of buffer media: bttv: remove crop info from bttv_buffer media: bttv: remove tvnorm field from bttv_buffer media: bttv: remove format field from bttv_buffer media: bttv: move do_crop flag out of bttv_fh media: bttv: copy vbi_fmt from bttv_fh media: bttv: copy vid fmt/width/height from fh media: bttv: radio use v4l2_fh instead of bttv_fh media: bttv: replace BUG with WARN_ON media: bttv: use video_drvdata to get bttv media: i2c: rdacm21: Fix uninitialized value media: coda: Remove duplicated include media: vivid: fix the racy dev->radio_tx_rds_owner media: i2c: ccs: Check rules is non-NULL media: i2c: ds90ub960: Fix PLL config for 1200 MHz CSI rate media: i2c: ds90ub953: Fix use of uninitialized variables ...
