- v4l-ioctl-test - This small utility sends dumb v4l2 ioctl to a device.
+ ioctl-test - This small utility sends dumb v4l2 ioctl to a device.
+
It is meant to check ioctl debug messages generated and to check
- if a function is implemented by that device.
+ if a function is implemented by that device. By compiling it as a
+ 32-bit binary on a 64-bit architecture it can also be used to test
+ the 32-to-64 bit compat layer.
+
+ In addition it also checks that all the ioctl values haven't changed.
+ This tool should be run whenever a new ioctl is added, or when fields
+ are added to existing structs used by ioctls.
+
+ To compile as a 32-bit executable when on a 64-bit architecture use:
+
+ gcc -o ioctl-test32 ioctl-test.c -I../../include -m32
