Previously, we were mixing the raw CPU frequency and CNTFRQ.
The raw CPU frequency (1020 MHz) should've never been used as CNTPCT (whose frequency is CNTFRQ) is the only counter available.
Moves it from Settings to Common::TimeZone, since this algorithm doesn't
depend on the setting. It also lets us use it in other libraries.
common: Various fixes
time_zone: Don't double up the std::abs
Too many absolute values were causing mirrored time zones to resolve
as the same.
Prevents needing to deduce the non-Switch setting in core. Instead, we
deduce the meaning of this setting where the heresy is committed, in
common.
settings: Remove strftime usage
GetTimeZoneString: Use standard features
Also forces GMT on MinGW due to broken strftime.
Track the private anonymous placeholder mappings created by Unmap() and
wherever possible, replace existing placeholders with larger ones
instead of creating many small ones.
This helps with the buildup of mappings in /proc/YUZU_PID/maps after a
longer gaming session, improving stability without having to increase
vm.max_map_count to a ridiculous value. The amount of placeholder
mappings will no longer outgrow the amount of actual memfd mappings in
cases of high memory fragmentation.
Previously, yuzu would try and guess which vsync mode to use given
different scenarios, but apparently we didn't always get it right. This
exposes the separate modes in a drop-down the user can select.
If a mode isn't available in Vulkan, it defaults to FIFO.
MicroSleep allows the processor to pause for a "short" amount of time (in the microsecond range). This is useful for spin-waiting that does not require nanosecond precision.
This uses the new TPAUSE instruction introduced on Intel's newest processors as part of the waitpkg instructions. For CPUs that do not support waitpkg instructions, this is equivalent to yield().
