The VIDIOCSMICROCODE is used only on this driver, and it requires some special program to upload a firmware, and a firmware blog. This one is enabled at MRG: $ grep -i STRA MRG/configs/kernel-2.6.33.7-rt29-mrg45-x86_64-rt* MRG/configs/kernel-2.6.33.7-rt29-mrg45-x86_64-rt.config:CONFIG_VIDEO_STRADIS=m MRG/configs/kernel-2.6.33.7-rt29-mrg45-x86_64-rtdebug.config:CONFIG_VIDEO_STRADIS=m MRG/configs/kernel-2.6.33.7-rt29-mrg45-x86_64-rttrace.config:CONFIG_VIDEO_STRADIS=m MRG/configs/kernel-2.6.33.7-rt29-mrg45-x86_64-rtvanilla.config:CONFIG_VIDEO_STRADIS=m Do you have any user using it and/or any hardware for testing, and the firmware files/userspace program to work with? We're removing this driver from kernel, as we couldn't find anyone using it upstream, and this is a really old driver, with several issues. Since the driver conversion from kernel 2.2 to 2.4, the driver author never updated it, so it became bit roted, with several issues. IMHO, the better would be to simply disable this driver, and remove the compat stuff from v4l2-compat.

I reopened this so that we can remove this piece of code like what the rhel-* kernels are (see mauro's patches in rhkernel-team-list). Also see, https://bugzilla.redhat.com/show_bug.cgi?id=642465#c8. Thanks.
