What is better is that if fork is > not available, this test is just skipped. Okay, try to find a solution for the no-mmu platform, but no progress. Anyway, if you update v4l2-utils to be compatible with the no-mmu platform, please let me know, i will retest this case, thanks. > > > > > - bypass VIDIOC_QUERYCAP nullptr check > > I'm not sure if this is the bug from my cross compile tool > > which created by buildroot. user area's nullptr can't be > > detected by kernel side, i was try to add access_ok() > > in v4l2-ioctl.c, but no help > > > > If this case must be fixed, i will continue to debug it. > > the error log: > > ... > > fail: v4l2-compliance.cpp(623): doioctl(node, VIDIOC_QUERYCAP, nullptr) != > > EFAULT > > .. > > Hmm, there is no mmu, so anything goes, really.

Okay, indeed, the application should check the NULL pointer. thanks. I will continue to debug on this case.
