[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

[PATCH v2 0/3] x86/vdso: Add Hyper-V TSC page clocksource support
Hi,
while we're still waiting for a definitive ACK from Microsoft that the
algorithm is good for SMP case (as we can't prevent the code in vdso from
migrating between CPUs) I'd like to send v2 with some modifications to keep
the discussion going.
Changes since v1:
- Document the TSC page reading protocol [Thomas Gleixner].
- Separate the TSC page reading code from
