Hey,
Linus released this Saturday v3.5 and there were quite a few
of interesting components/fixes/features that went in!
Going to go down the list of what shortlog provided:
- Less MSR traps when using AMD machines - so better performance. [andre]
- The APIC IPI interface works - which means that ''perf'' in
the initial
domain works. So no more lockups. Also with some tweaks, that means kdb
can work as well [ben]
- Static analyzer fixes in hvc [dan]
- The march to make HVM domains driver domains continue - the XenBus
in the initial domain can now search for it in another domain instead
of assuming its in the initial domain [daniel]. Marek also expanded netfront
to now work in initial domain. [marek]
- Memory reported by ''xm list'' for the initial domain now
matches what
the kernel has been booted with. In the past it would be around 1GB
less due to the kernel releasing memory that fall within
E820 gaps/PCI space [david and me]
- The bootup on two-socket or more of AMD cpus works correctly (I put
in a temporary way in v3.4) but Lin implemented the correct way [lin, jeremy
and me]
- Make xen-blkfront capable of unloading. This requires some extra
infrastructure work to handle delayed grants [jan]
- Fixes in the hvc drivers for PVonHVM guests started with
''xm'' (not xl!) would
fail during migration. [me]
- Fix in blkback with discard operation in 32/64 (so 32-bit guest, 64-bit dom0)
mix would fail.
- Support for ''perf'' to work in the initial domain [lin]
- PVonHVM guests on their reboot would not release properly event channels
so would consume additional memory [stefano]
- Make it possible for the upstream QEMU run in the initial domain along with
blkfront (and blkback) to allow QCOW images to be mapped [stefano]
- Fix for mulitple PCI domains to not crash during bootup [zhang]
- Fix to make FLR actually do properly FLR in xen-pciback. [me]
