Implement guest-shutdown RPC for Windows. Functionally this should be
equivalent to the posix implementation.
Original patch by Gal Hammer <ghammer@redhat.com>
This allows qemu-ga to function as a Windows service:
- to install the service (will auto-start on boot):
qemu-ga --service install
- to start the service:
net start qemu-ga
- to stop the service:
net stop qemu-ga
- to uninstall service:
qemu-ga --service uninstall
Original patch by Gal Hammer <ghammer@redhat.com>
This adds a win32 channel implementation that makes qemu-ga functional
on Windows using virtio-serial (unix-listen/isa-serial not currently
implemented). Unlike with the posix implementation, we do not use
GIOChannel for the following reasons:
- glib calls stat() on an fd to check whether S_IFCHR is set, which is
the case for virtio-serial on win32. Because of that, a one-time
check to determine whether the channel is readable is done by making
a call to PeekConsoleInput(), which reports the underlying handle is
not a valid console handle, and thus we can never read from the
channel.
- if one goes as far as to "trick" glib into thinking it is a normal
file descripter, the buffering is done in such a way that data
written to the output stream will subsequently result in that same
data being read back as if it were input, causing an error loop.
furthermore, a forced flush of the channel only moves the data into a
secondary buffer managed by glib, so there's no way to prevent output
from getting read back as input.
The implementation here ties into the glib main loop by implementing a
custom GSource that continually submits asynchronous/overlapped I/O to
fill an GAChannel-managed read buffer, and tells glib to poll the
corresponding event handle for a completion whenever there is no
data/RPC in the read buffer to notify the main application about.
Various stubs and #ifdefs to compile for Windows using mingw
cross-build. Still has 1 linker error due to a dependency on the
forthcoming win32 versions of the GAChannel/transport class.
Many of the current RPC implementations are very much POSIX-specific
and require complete re-writes for Windows. There are however a small
set of core guest agent commands that are common to both, and other
commands such as guest-file-* which *may* be portable. So we introduce
commands.c for the latter, and will rename guest-agent-commands.c to
commands-posix.c in a future commit. Windows implementations will go in
commands-win32.c, eventually.
This is mostly in preparation for the win32 port, which won't use
GIO channels for reasons that will be made clearer later. Here the
GAChannel class is just a loose wrapper around GIOChannel
calls/callbacks, but we also roll in the logic/configuration for
various channel types and managing unix socket connections, which makes
the abstraction much more complete and further aids in the win32 port
since isa-serial/unix-listen will not be supported initially.
There's also a bit of refactoring in the main logic to consolidate the
exit paths so we can do common cleanup for things like pid files, which
weren't always cleaned up previously.
Since we might want to test arbitrary qemu, qemu-img and
qemu-io paths, allow users to specify environment variable
values for QEMU_PROG, QEMU_IMG_PROG and QEMU_IO_PROG so
the testsuite will use those values rather than find them
on PATH. Obviously, if such env variables are not set
prior to script execution, normal detection mechanism
takes place.

Until recently, qemu-img create displayed cluster_size=0 for the default
cluster size. It is changed to display the real cluster size now, which results
in the cluster size not being filtered out any more.
If the cluster size is specified explicitly in CLUSTER_SIZE, keep the output,
and if using the default, filter it out. This mostly restores the old behaviour
of the test cases; test 015 must be fixed to use CLUSTER_SIZE instead of using
extra_img_options for it.

The io_pattern style functions have the following loop:
for i in `seq 1 $count`; do
echo ... $(( start + i * step )) ...
done
Offsets are 1-based so start=1024, step=512, count=4 yields:
1536, 2048, 2560, 3072
Normally we expect:
1024, 1536, 2048, 2560
Most tests ignore this detail, which means that they perform I/O to a
slightly different range than expected by the test author.
Later on things got less innocent and tests started trying to compensate
for the 1-based indexing. This included negative start values in test
024 and my own attempt with count-1 in test 028!
The end result is that tests that use io_pattern are hard to reason
about and don't work the way you'd expect. It's time to clean this mess
up.
This patch switches io_pattern to 0-based offsets. This requires
adjusting the golden outputs since I/O ranges are now shifted and output
differs.
Verifying these output diffs is easy, however. Each diff hunk moves one
I/O from beyond the end of the pattern range to the beginning.

This version doesn't have the duplicate feature bits on extfeature_edx, though,
as they are being removed from the Intel models (as they are reserved bits on
Intel CPUs).
Version 1 patch description:
This patch adds Westmere as a qemu cpu model. The only
additional guest visible feature of a Westmere relative
to Nehalem is the inclusion of AES instructions. However
as other non-ABI visible modifications exist along with
fabrication changes, the CPUID data of the corresponding
deployed silicon was altered slightly to reflect this.
We've seen isolated cases where apparently unrelated yet
slightly incoherent CPUID data has caused problems, most
notably during guest boot. Providing Westmere as a
model separate fro Nehalem allows us to more easily address
such quirks.

(extfeature_edx) from Intel models, as the duplicated feature flags are present
only on AMD CPUs. On Intel models, only the i64, syscall, and xd flags are kept
on extfeature_edx.

cpu model bug fixes and definition corrections
This patch was intended to address the replicated feature
flags in cpuid 8000_0001:edx from cpuid 0000_0001:edx.
This is due to AMD's definition where these flags are
mostly cloned in the 8000_0001:edx cpuid function.
qemu64 attempted to glue together the respective Intel
and AMD nearly disjoint features and this propagated to
the new Intel models as doing so was believed conservative
at the time. However after further soak and test lugging
around this cruft doesn't provide any value, could
conceivably confuse a guest, and has confused users trying
to maintain/add cpu definitions. This also caused issues
for libvirt attempting to track this mis-encoding.
So we've here tossed out the AMD replicated definitions
from the Intel models, added a few replications into AMD
definitions which were missing according to AMD's latest
CPUID document, and reordered the config file flags to
follow intuitive sequential bit ordering. Also two flag
name aliases were added for clarity to Intel models. The
end result being the models definitions now conform to
their respective cpuid specifications sans x2apic which is
emulated by kvm.
This was tested with the following combinations:
[Conroe, Penryn, Nehalem] x [F12-64, win64, win32] -- Intel host
[Opteron_G1, Opteron_G2, Opteron_G3] x [F12-64, win64, win32] -- AMD host
