2021-11-30media: mtk-vcodec: fix debugging definesDafna Hirschfeld
The mtk-vcodec uses some internal defined debug formats for printing. This patch fixes some things in those defines: 1. use the 'pr_fmt' define to print function name and line. 2. remove 'if(DEBUG)' condition for the defines. This condition prevents the debugs from being shown in case of dynamic debugs. Instead replace 'pr_info' with 'pr_debug' 3. remove module parameters that enable/disable debug. There is no reason for the driver to have those params. Having those params require the user to explicitly set them when user wants to see debug prints instead of using the global debugs setting as expected by drivers to conform. In addition to that, fix some warnings about debug formatting [hverkuil: used %zu instead of %lu for sizeof() arguments] Signed-off-by: Dafna Hirschfeld <dafna.hirschfeld@collabora.com> Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

2021-09-30media: mtk-vcodec: vdec: move stateful ops into their own fileYunfei Dong
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.

2021-09-30media: mtk-vcodec: venc: support START and STOP commandsAlexandre Courbot
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.

2021-09-30media: mtk-vcodec: make flush buffer reusable by encoderAlexandre Courbot
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.

2021-09-30media: mtk-vcodec: vdec: clamp OUTPUT resolution to hardware limitsAlexandre Courbot
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.
