Discover monotonic clock using compile-time check
|
|
|
|
monotonic clock check does not work when cross-compiling.

Original patch follows:
|
|
|
|
When xorg-xserver is being cross-compiled, there is currently no way
|
|
for us to detect whether the monotonic clock is available on the
|
|
target system, because we aren't able to run a test program on the host
|
|
system. Currently, in this situation, we default to not use the
|
|
monotonic clock. One problem with this situation is that the user will
|
|
be treated as idle when the date is updated.
|
|
|
|
To fix this situation, we now use a compile-time check to detect whether the
|
|
monotonic clock is available. This check can run just fine when we are
|
|
cross-compiling.
