* media: visl: add virtual stateless decoder driverDaniel Almeida2022-11-252-0/+176
| | | | | | | | | | | | | | | | | | | | | | | | | | A virtual stateless device for stateless uAPI development purposes. This tool's objective is to help the development and testing of userspace applications that use the V4L2 stateless API to decode media. A userspace implementation can use visl to run a decoding loop even when no hardware is available or when the kernel uAPI for the codec has not been upstreamed yet. This can reveal bugs at an early stage. This driver can also trace the contents of the V4L2 controls submitted to it. It can also dump the contents of the vb2 buffers through a debugfs interface. This is in many ways similar to the tracing infrastructure available for other popular encode/decode APIs out there and can help develop a userspace application by using another (working) one as a reference. Note that no actual decoding of video frames is performed by visl. The V4L2 test pattern generator is used to write various debug information to the capture buffers instead.

| | | | | | | | | | | | | | | | | | | Rename the imx7-mipi-csis.c driver to remove the reference to i.MX7. The driver is for an IP core found on i.MX7 and i.MX8 SoC, so do not specify a SoC version number in the driver name. Remove the references to the i.MX7 SoC in the driver symbols and expand the driver's header with more information about the IP core the driver controls. Also rename the associated bindings documentation.

* media: vimc: Add support for contiguous DMA buffersLaurent Pinchart2022-02-161-0/+13
| | | | | | | | | | | | | | | | | | The vimc driver is used for testing purpose, and some test use cases involve sharing buffers with a consumer device. Consumers often require DMA contiguous memory, which vimc doesn't currently support. This leads in the best case to usage of bounce buffers, which is very slow, and in the worst case in a complete failure. Add support for the dma-contig allocator in vimc to support those use cases properly. The allocator is selected through a new "allocator" module parameter, which defaults to vmalloc.
