Hey,
Linux 3.3 merge window opened last week and today I''ve asked Linus
to pulled some of the patches. This is what is going in through
the Xen tree:
- SysFS documentation updates. We are slowly updating them to make sure that
the SysFS
entires are properly documented.
- Making the grant system able to use more fancier types of grants to speed-up
guest to guest exchange of data (sub-page and transitive grants).
- Updates in the backends to be able to export the Xen backends in an
Hardware Virtualized Management (HVM) guest. We usually export those backends
in
the initial domain (dom0), but are moving slowly to make it possible to do it
any guest
(PV or HVM). NOTE: Only the netback version is in. The blkback needs an
Ack from Jens Axboe and while I am sure he will provide it it might be past
the
merge window time-frame.
- Better driver to deal with memory type ioctls calls. In the past we were
doing
ioctls on /proc/xen/priv_cmd (yuck) and with this are moving to doing it in
/dev/xen/priv_cmd.
- Fix a security issues were the guest could try to send a nasty (out of band)
message and potentially cause mishap.
- Remove duplicate initialization fields in the backend drivers.
- Jeremy is now working for a fancy new startup so changing the MAINTAINERS
file to
reflect that his contribution are done during his private time.
- Sensible config options. We had some that weren''t all that good so
adjusting
them properly.
- Bug-fixes, fixing a bug in xen-pciback with the "Ownership but
beware" bug.
In the Dave Airlie tree (DRM, graphics) the TTM DMA backend is going in. It
allows the TTM
to pre-allocate (and setup DMA for them) the pages for graphics (similar to how
network
layers do it) before using them. This means that both radeon and nouveau 32-bit
cards
can now work properly with Xen, so that ATI ES1000 found in most server boxes
will now
run X. 64-bit cards work just fine.

We started the discussion about the patches and we have an thought of how to rework them. So it will have to wait :-(> Is it rigth?<nods> But the moment they are ready to be posted we will make sure you are CC-ed on them. There will be undoubtly some bugs we haven''t found and you have this sixth sense in finding them :-) Thanks!

It is TRIM/UNMAP with the option of securely erasing the media.
