New Revision: 320043
URL: https://svnweb.freebsd.org/changeset/base/320043
Log:
Add abstime kqueue(2) timers and expand struct kevent members.
This change implements NOTE_ABSTIME flag for EVFILT_TIMER, which
specifies that the data field contains absolute time to fire the
event.
To make this useful, data member of the struct kevent must be extended
to 64bit. Using the opportunity, I also added ext members. This
changes struct kevent almost to Apple struct kevent64, except I did
not changed type of ident and udata, the later would cause serious API
incompatibilities.
The type of ident was kept uintptr_t since EVFILT_AIO returns a
pointer in this field, and e.g. CHERI is sensitive to the type
(discussed with brooks, jhb).
Unlike Apple kevent64, symbol versioning allows us to claim ABI
compatibility and still name the new syscall kevent(2). Compat shims
are provided for both host native and compat32.

This, or one of the following commits breaks my nfs mounts on powerpc64.
With the following I mean, 320044-46. The last working revision is 320038.
With this revision I get this error:
RPCPROG_NFS: RPC: Port mapper failure - RPC: Unable to receive
Boot is ok beside not having nfs.
Right now I build the latest trunk to be sure to test against jhibbit's
latest commit in this area. But I do not expect a change.
Any idea where to look for suspects?
Start with ktrace-ing the mount command, assuming the direct invocation of
mount_nfs(8) fails.
Hm, if you could give me some hands-on? How do I do that?
Did you rebuilt the world after the update ? It should work both ways,
but knowing the answer trims half of the change for suspect.
I built world and kernel in a clean env. rm -rf the obj part.
The whole boot is done via nfs. I do boot the tree via netboot,
crossbuilt on amd64. The machine is shot I can not boot from disk atm.
With the r320421, the picture is the same, as expected.
Can you run the ktrace tests on ppc ?
cd tests/sys/kqueue/libkqueue/
make
./kqtest
This is chicken and egg, my src is on the nfs drive :(
I'll check-out a src tree on this machine tomorrow and do test build/run.
Thx for the feedback!
Andreas
