devm functions are fine for managing resources that are directly related to the device at hand and that have no other dependencies. However, a process holding a file handle to a device created by a driver for a device may result in the file handle left behind after the device is long gone. This will result in accessing released (and potentially reallocated) memory. Instead, manage the memory resources in the driver. Releasing the resources can be later on bound to e.g. by releasing a reference. Signed-off-by:

The size of the vma can be larger than the size of the backing buffer. Use the buffer size over vma size to prevent exposing extra memory to userspace. Signed-off-by:

The A83T SoC has a camera sensor interface (known as CSI in Allwinner lingo), which is similar to the one found on the A64 and H3. The only difference seems to be that support of MIPI CSI through a connected MIPI CSI-2 bridge. Add support for this variant. Signed-off-by:

This commit adds the needed boilerplate code to support the VPU in decoding operation. Two v4l2 interfaces are exposed, one for encoding and one for decoding, but a single m2m device is shared by them, so jobs are properly serialized. Signed-off-by:

Boris Brezillon authored
The code in rockchip_vpu_v4l2 was hardcoded for encoder support. Modify it more generic to support the decoder case so that we can re-use the same vb2/v4l2 ops for both devices. Co-developed-by:

When initializing a context, the core wants to reset both src and dst formats. Right now the order doesn't matter, but if we want to have a valid default width/height on the non-coded/raw format side (src in case of encoders, dst in case of decoders), we need to reset those formats in the right order: first the coded-format side, then the other, such that width and height on the raw format side can be taken from the coded format. Let's provide a helper that will reset both formats and make sure this is done in the right order. Signed-off-by:

Boris Brezillon authored
The V4L2/VB2 implementation for the encoder and decoder logic are very similar, so let's rename rockchip_vpu_enc.c file into rockchip_vpu_v4l2.c and remove the _enc_ part in objects/functions exposed in rockchip_vpu_v4l2.h. We also rename the enc_queue_init() function (in rockchip_vpu_drv.c) queue_init() since it will be used to initialize both type of queues. The implementation itself will be patched to support the decoding case when decoder support is added. Suggested-by:

We're about to add prototypes for the vb2/v4l2 helpers shared by the encoder/decoder logic in this file, so let's pick a name that reflects that (rockchip_vpu_common.h was a bit to generic). Suggested-by:

In preparation to support decoders, using a single memory-to-memory device, we need to roll our own media controller entities registration. To do that, we define a rockchip_vpu_func object that embeds the video_device object plus all the elements that are needed to attach this vdev to the media device. Signed-off-by:
