[Minios-devel] Missing ukplat_monotonic_clock for KVM platform

[Wei Chen <Wei.Chen@xxxxxxx>]

Hi Simon,

While I am testing ARM64 KVM patches. I found the ukplat_monotonic_clock was
missing for KVM platforms (x86_64 and ARM). I have implemented this function
for ARM64 KVM, and the timestamp can print properly for debug messages now.
But on x86_64 KVM, we still get following error.

/home/weic/WIP/unikraft/unikraft/build/libukdebug.o: In function 
`_printd_timestamp':
/home/weic/WIP/unikraft/unikraft/lib/ukdebug/print.c:88: undefined reference to 
`ukplat_monotonic_clock'

Should we port tscclock driver from solo5 to fix this issue?
