Hi,
Microsoft and Intel developed two different ACPI NVDIMM _DSM interfaces.
The specs for the Intel interface are available here:

This is a resubmit of David Edmondson's series at

After closer analysis on IRC, the CoRwLock's attempt to ensure
fairness turned out to be flawed. Therefore, this series
reimplements CoRwLock without using a CoQueue. Tr

Test that downgrading an rwlock does not result in a failure to
schedule coroutines queued on the rwlock.
The diagram associated with test_co_rwlock_downgrade() describes the
intended behaviour, but what was observed previously corresponds to:
| c1 | c2 | c3
Test that rwlock upgrade is fair, and readers go back to sleep if a writer
is in line.

Given that the block size is read from the header of the VDI file, a

An invariant of the current rwlock is that if multiple coroutines hold a
reader lock, all must be runnable. The unlock implementation relies on
this, choosing to wake a single coroutine when the final read lock
holder exits the critical section, assuming that it will wake a
coroutine attempting to
