[PATCH 0/2] x86/vdso: Add Hyper-V TSC page clocksource support
Hi,
Hyper-V TSC page clocksource is suitable for vDSO, however, the protocol
defined by the hypervisor is different from VCLOCK_PVCLOCK. Implemented the
required support. Simple sysbench test shows the following results:
Before:
# time sysbench --test=memory --max-requests=500000 run
...
real 1m22.618s
user 0m50.193s
sys 0m32.268s
After:
# time sysbench --test=memory
