2022-06-27media: mediatek: vcodec: Skip SOURCE_CHANGE & EOS events for statelessChen-Yu Tsai1-0/+5
The stateless decoder API does not specify the usage of SOURCE_CHANGE and EOF events. These events are used by stateful decoders to signal changes in the bitstream. They do not make sense for stateless decoders. Do not handle subscription for these two types of events for stateless decoder instances. This fixes the last v4l2-compliance error: Control ioctls: fail: v4l2-test-controls.cpp(946): have_source_change || have_eos test VIDIOC_(UN)SUBSCRIBE_EVENT/DQEVENT: FAIL Fixes: 8cdc3794b2e3 ("media: mtk-vcodec: vdec: support stateless API") Signed-off-by: Chen-Yu Tsai <wenst@chromium.org> Reviewed-by: Nicolas Dufresne <nicolas.dufresne@collabora.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>

2022-06-27media: atmel: atmel-isc-base: allow wb ctrls to be changed when isc is not configuredEugen Hristev1-4/+0
When attempting to change the white balance (WB) ctrls before starting streaming, e.g.: # v4l2-ctl -L User Controls .. blue_component_gain 0x009819c1 (int) : min=0 max=8191 step=1 default=512 value=512 flags=slider .. # v4l2-ctl --set-ctrl=blue_component_gain=500 # v4l2-ctl -L .. blue_component_gain 0x009819c1 (int) : min=0 max=8191 step=1 default=512 value=500 flags=slider .. These will not be written to the internal data struct and will not be written to the WB hardware module. Thus, after starting streaming, they will be reset to default: # v4l2-ctl -L .. blue_component_gain 0x009819c1 (int) : min=0 max=8191 step=1 default=512 value=512 flags=slider .. It does not make much sense to not be able to configure the WB controls at all times. Even if the sensor would not be RAW Bayer (and in this case the WB module is unavailable), the user could configure the ISC itself, as the ISC should not care about the sensor format. Thus, when WB module is available (if the sensor changes format e.g.) it will be already configured as be user's desires. In consequence, remove the check in isc_s_awb_ctrl that will return if ISC does not know the sensor format.

2022-06-20media: mediatek/vcodec: Enable incoherent buffer allocationJustin Green1-0/+2
Set allow_cache_hints to 1 for the vb2_queue source and destination queues in the mediatek vcodec V4L2 driver. This allows us to allocate buffers with the V4L2_MEMORY_FLAG_NON_COHERENT set. On Mediatek SoCs, this enables caching for this memory, which vastly improves performance when being read from CPU. Read performance for these buffers is in turn important for detiling MM21 video frames in userspace software, such as libyuv or gstreamer. This change should be safe from race conditions since videobuf2 already invalidates or flushes the appropriate cache lines in its prepare() and finish() methods. Tested on a MT8183 SoC. Resulted in both correct detiling and a 10X speedup.

2022-06-20media: amphion: Replace zero-length array with flexible-array memberKees Cook1-1/+1
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2][3].

2022-06-20media: mediatek: vcodec: Use kmemdup rather than kmalloc/memcpyHaowen Bai1-2/+1
kmemdup is introduced to duplicate a region of memory in a neat way. Rather than kmalloc/kzalloc + memcpy, which the programmer needs to write the size twice (sometimes lead to mistakes), kmemdup improves readability, leads to smaller code and also reduce the chances of mistakes. Suggestion to use kmemdup rather than using kmalloc/kzalloc + memcpy.

2022-06-20media: atmel: atmel-isc-base: move cropping settings outside start_dmaEugen Hristev1-4/+10
The cropping configuration of the Parallel Front Engine (PFE) can be done just once when the streaming starts. The ISC configuration is in place and will not be changed while streaming. It is not effective to keep rewriting the crop registers configuration everytime start_dma is called, as this can be called for each queued buffer. Thus we can configure the cropping at start_streaming time. This change moves the code to a dedicated function.
