2020-02-12Remove support for CLOCK_MONOTONIC not being definedPeter Maydell1-7/+4
Some older parts of QEMU's codebase assume that CLOCK_MONOTONIC might not be defined by the host OS, and have workarounds to deal with this. However, more recently (notably in commit 50290c002c045280f8d for qemu-img in mid-2019, but also much earlier in 2011 in commit 22795174a37e0 for ui/spice-display.c) we've written code that assumes CLOCK_MONOTONIC is always defined. The only host OS anybody's ever noticed this on is OSX 10.11 and earlier, which we don't support. So we can assume that all our host OSes have the #define, and we can remove some now-unnecessary ifdefs.

2013-04-04Allow clock_gettime() monotonic clock to be utilized on more OS'sBrad Smith1-3/+1
Allow the clock_gettime() code using monotonic clock to be utilized on more POSIX compliannt OS's. This started as a fix for OpenBSD which was listed in one function as part of the previous hard coded list of OS's for the functions to support but not in the other.
