lib/igt_aux: Divert ioctls for signal injection
To simplify and speed up running interruptible tests, use a custom ioctl() function that control the signaling and detect when we need no more iterations to trigger an interruption. We use a realtime timer to inject the signal after a certain delay, increasing the delay on every loop to try and exercise different code paths within the function. The first delay is very short such that we hopefully enter the kernel with a pending signal. Clients should use struct igt_sigiter iter = {}; while (igt_sigiter_repeat(&iter, enable_interrupts=true)) do_test() to automatically repeat the test until we can inject no more signals into the ioctls. This is condensed into a macro igt_interruptible(enable_interrupts=true) do_test(); for convenience. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
