Firmwares for decoders newer than MT8173 will include an ABI version number in their initialization ack message. Add the capacity to manage it and make initialization fail if the firmware ABI is of a version that we don't support. For MT8173, this ABI version field does not exist ; thus ignore it on this chip. There should only be one firmware version available for it anyway. Signed-off-by:

We are planning to add support for stateless decoders to this driver. Part of the driver will be shared between stateful and stateless codecs, but a few ops need to be specialized for both. Extract the stateful part of the driver and move it into its own file, accessible through ops that the common driver parts can call. This patch only moves code around and introduces a set of abstractions ; the behavior of the driver should not be changed in any way. Changes to code styling has been done to accommodate 'checkpatch.pl --strict'. [acourbot: refactor, cleanup and split] [tzungbi: fix errors from 'checkpatch.pl --strict'] Signed-off-by:

The V4L2 encoder specification requires encoders to support the V4L2_ENC_CMD_START and V4L2_ENC_CMD_STOP commands. Add support for these to the mtk-vcodec encoder by reusing the same flush buffer as used by the decoder driver. [hsinyi: fix double-free issue if flush buffer was not dequeued by the time streamoff is called] Signed-off-by:

The flush buffer is a special buffer that tells the decoder driver to send an empty CAPTURE frame to the client with V4L2_BUF_FLAG_LAST set. We need similar functionality for the encoder ; however currently the flush buffer depends on decoder-specific structures and thus cannot be reused with the encoder. Fix this by testing for this buffer by its VB2 address, and not through a dedicated flag stored in a higher-level decoder structure. This also allows us to remove said flag and simplify the code a bit. Since the flush buffer should never be used in the stateless decoder, also add safeguards to check against it. Signed-off-by:

Calling S_FMT or TRY_FMT on the OUTPUT queue should adjust the resolution to the limits supported by the hardware. Until now this was only done on the CAPTURE queue, which could make clients believe that unsupported resolutions can be used when they set the coded size on the OUTPUT queue. In the case of the stateless decoder, the problem was even bigger since subsequently calling G_FMT on the CAPTURE queue would result in the unclamped resolution being returned, further inducing the client into error.

Currently the null pointer check on dvb_spi->vcc_supply is inverted and this leads to only null values of the dvb_spi->vcc_supply being passed to the call of regulator_disable causing null pointer dereferences.

Add more information about V4L2_PIX_FMT_NV12MT and V4L2_PIX_FMT_NV12M_16X16, so it's clearer for driver authors and users. Also, group the two pixel formats with the other tiled formats, for clarity. Unlike the recently introduced tiled formats (V4L2_PIX_FMT_NV12_4L4, etc) these formats have remained Samsung-specific until now. Therefore, and although the NV12MT and NV12MT_16X16 nomenclatures are less clear, we are keeping them as-is. Signed-off-by:

If you image search "microdia sonix webcam", or SN9C120, you can find examples of the type of webcam I have. It has 6 built-in LEDs. It's ancient (2006 maybe?) but in 2020 it was the only USB webcam I had. It doesn't perform well, especially in low light. The Windows XP drivers had the ability to toggle the LEDs, as well as "Auto" mode which would read and adjust the exposure and turn them on when it got "too dark", along with other nice features, like smoothing dead pixels, funky filters, effects and face tracking. Watching Wireshark usbmon with the Windows driver I was able to discover which values are required to toggle the LEDs. Reading ext-ctrls-flash.rst, V4L2_FLASH_LED_MODE_TORCH seems to describe mostly what I want it to do. Ideally the control would be boolean/checkbox, but the existing implementation seems to require a menu. This patch implements the ability to control the LEDs, attempting to minimise changes to external files and other webcams. Review by anyone more familiar with the code base for unintended side effects would be welcome and appreciated. First kernel submission. Signed-off-by:

There is likely a typo here. To be consistent, we should compare 'fmt.height' with 'ctx->out.pix_fmt.height', not 'ctx->out.pix_fmt.width'.

The combination of supports_requests == 1 and min_buffers_needed > 0 is not allowed, WARN on that and return an error. Also check that if vb2_core_qbuf() is called from req_queue, that it doesn't return an error, unless it is -EIO. Signed-off-by:

Hans Verkuil authored
Currently vivid supports the Request API, but it also sets min_buffers_needed in the vb2 queue. But the combination of support_requests and min_buffers_needed is not allowed due to the fact that vb2_core_qbuf() isn't supposed to fail when called from the request framework. And if min_buffers_needed > 0, then is can call start_streaming() which definitely can fail. With the new module option you can control if requests are not allowed (min_buffers_needed is 2 in that case), optionally allowed or are required. In the latter two cases min_buffers_needed is set to 0. Signed-off-by:

Hans Verkuil authored
There is no reason for the cedrus driver to set min_buffers_needed. A non-zero min_buffers_needed can cause problems with the Request API if start_streaming fails when queueing a buffer from a request. Since it is not needed for this driver, just remove it. Signed-off-by:

Robert Foss authored
vfe_set_power() is invoked a few times, which causes a lot of VFE HW version prints. Secondly there is no real reason for calling hw_version_read() from this location specifically, since it does nothing more than print the VFE HW version. A better location for the hw_version_read() call would be somewhere which is only executed once per VFE unit. Signed-off-by:
