Hello,
Here's the fourth version of the Xilinx FPGA Video IP Cores kernel drivers.
I won't detail in great lengths the Xilinx Video IP architecture here, as that
would result in dozens of pages of documentation. The interested reader can
refer to the Zynq ZC702 Base TRD (Targeted Reference
The vb2_fop_poll() implementation tries to be clever on whether it needs
to lock the queue mutex by checking whether polling might start fileio.
The test requires reading the q-num_buffer field, which is racy if we
don't hold the queue mutex in the first place.
Remove the extra cleverness and

Keep the formats sorted by type, bus_width, bits per component, samples
per pixel and order of subsamples, in that order.

The function fills a link data structure with the device node and port
number at both the local and remote ends of a link defined by one of its
endpoint nodes.

The function releases the queue if the file being released is the queue
owner. The check reads the queue-owner field without taking the queue
lock, creating a race condition with functions that set the queue owner,
such as vb2_ioctl_reqbufs() for instance.
Fix this by moving the queue-owner check
The TPG generates multiple static or dynamic test patterns. The driver
currently hardcodes the pattern to the moving box pattern.

Xilinx platforms have no hardwired video capture or video processing
interface. Users create capture and memory to memory processing
pipelines in the FPGA fabric to suit their particular needs, by
instantiating video IP cores from a large library.
The Xilinx Video IP core is a framework that

Hi
I am facing an issue while using videobuf2-dma-contig.c mem_ops. Following
is brief description of the driver architecture and the limitation. Any
pointers/hints are appreciated.
Driver architecture:
It is a video codec driver for video decoding. It exposes two ports -
CAPTURE and OUTPUT. Raw

Another update suggestion was taken into account after a patch was applied
from static source code analysis.

The release_firmware() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.

The release_firmware() function was called by the mn88473_init() function even
if a previous function call request_firmware failed.
This implementation detail could be improved by the introduction of another
