2020-01-07tests/iothread: Always connect iothread GSource to a GMainContextPeter Maydell1-0/+30
On older versions of glib (anything prior to glib commit 0f056ebe from May 2019), the implementation of g_source_ref() and g_source_unref() is not threadsafe for a GSource which is not attached to a GMainContext. QEMU's real iothread.c implementation always attaches its iothread->ctx's GSource to a GMainContext created for that iothread, so it is OK, but the simple test framework implementation in tests/iothread.c was not doing this. This was causing intermittent assertion failures in the test-aio-multithread subtest "/aio/multi/mutex/contended" test on the BSD hosts. (It's unclear why only BSD seems to have been affected -- perhaps a combination of the specific glib version being used in the VMs and their happening to run on a host with a lot of CPUs). Borrow the iothread_init_gcontext() from the real iothread.c and add the corresponding cleanup code and the calls to g_main_context_push/pop_thread_default() so we actually use the GMainContext we create.

On Linux, calling `reboot(RB_AUTOBOOT);` will result in arch/m68k/mac/misc.c's mac_reset function being called. That in turn looks at the rombase (or uses 0x40800000 is there's no rombase), adds 0xa, and jumps to that address. At the moment, there's nothing there, so the kernel just crashes when trying to reboot. So, this commit adds a very simple implementation at that location, which just writes to via2 to power down.

'remotes/elmarco/tags/dbus-vmstate7-pull-request' into staging Add dbus-vmstate Hi, With external processes or helpers participating to the VM support, it becomes necessary to handle their migration. Various options exist to transfer their state: 1) as the VM memory, RAM or devices (we could say that's how vhost-user devices can be handled today, they are expected to restore from ring state) 2) other "vmstate" (as with TPM emulator state blobs) 3) left to be handled by management layer 1) is not practical, since an external processes may legitimatelly need arbitrary state date to back a device or a service, or may not even have an associated device. 2) needs ad-hoc code for each helper, but is simple and working 3) is complicated for management layer, QEMU has the migration timing The proposed "dbus-vmstate" object will connect to a given D-Bus address, and save/load from org.qemu.VMState1 owners on migration. Thus helpers can easily have their state migrated with QEMU, without implementing ad-hoc support (such as done for TPM emulation) D-Bus is ubiquitous on Linux (it is systemd IPC), and can be made to work on various other OSes. There are several implementations and good bindings for various languages. (the tests/dbus-vmstate-test.c is a good example of how simple the implementation of services can be, even in C) dbus-vmstate is put into use by the libvirt series "[PATCH 00/23] Use a slirp helper process". v2: - fix build with broken mingw-glib # gpg: Signature made Mon 06 Jan 2020 14:43:35 GMT # gpg: using RSA key 87A9BD933F87C606D276F62DDAE8E10975969CE5 # gpg: issuer "marcandre.lureau@redhat.com" # gpg: Good signature from "Marc-André Lureau <marcandre.lureau@redhat.com>" [full] # gpg: aka "Marc-André Lureau <marcandre.lureau@gmail.com>" [full] # Primary key fingerprint: 87A9 BD93 3F87 C606 D276 F62D DAE8 E109 7596 9CE5 * remotes/elmarco/tags/dbus-vmstate7-pull-request: tests: add dbus-vmstate-test tests: add migration-helpers unit dockerfiles: add dbus-daemon to some of latest distributions configure: add GDBUS_CODEGEN Add dbus-vmstate object util: add dbus helper unit docs: start a document to describe D-Bus usage vmstate: replace DeviceState with VMStateIf vmstate: add qom interface to get id Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
