25df76591e The fsync hypercall is now used only with close, so get rid of it. 
rumpuser_bio() should do the necessary syncing.

9dda4d8626 Give private hypercalls the ability to meddle with kthread contexts too. 2013-04-29 15:20:05 +00:00

5af3856aee Make the rump kernel upcalls which were previous available only to 
the sysproxy module available for the entire hypervisor.

696d8241ab changes to bio hypercalls, part 3/n: 
retire the filemmap/memsync hypercalls, they're no longer used

262a3aaf9f Rework how the bio hypercalls work, part 1/n: 
Reduce the set of hypercalls to one: "do block i/o".  This not only
eliminates a lot of pseudo-duplicate code, it also gives the
hypervisor a lot more freedom on how to optimize the i/o.

49bb662cc0 Change rumpuser_cv_timedwait() from absolute time to relative time. 
It's then the hypervisor's problem to translate it accordingly.
Now we no longer have to worry about the kernel having to know the
hypervisor's time and vice versa.

a53a2a5357 Improve the time-related hypercalls so that's it's possible to 
sleep until an absolute time on the host's monotonic clock (should
something like that be supported).

b985b935c6 The ioctl hypercall is used only by the usb host controller driver, 
so make it exclusive to that component.  I'm happy to see it gone.

bc3aabc030 Try to make sure that the appropriate calls to mutex_enter() takes 
a spin mutex (i.e. does not relinquish cpu context while trying to
take the mutex).

Bump the hypercall interface version number.  I'll be doing a bunch
of other cleanups to simplify the interface for the benefit of
alternative hypervisor implementations.  I'll be riding this bump
and doing a second one only after I'm finished with all of the
changes.
