[igt-dev] [PATCH i-g-t 1/2] lib: Only require we have i915.reset module parameter for allow-hang

[Chris Wilson]

To control hang detection, we manipulate the i915.reset module
parameter. However, to be nice we should SKIP if we cannot modify the
parameter as opposed to outright FAILing.

[igt-dev] [PATCH i-g-t 2/2] igt/drv_hangman: Skip if resets are disallowed

[Chris Wilson]

If we tell the machine to reset but they are disallowed, we will leave
the system in a wedged state, preventing the majority of subsequent
tests.

How come we were not able to write that parameter? Isn't that sysfs 
always there?

No. It can be compiled out.
