* glib-compat.h: change assert to g_assertMichael Tokarev2015-05-081-3/+3
| | | | | | | | | | | include/glib-compat.h defines a bunch of functions based on glib primitives, and uses assert() without including assert.h. Replace assert() with g_assert() to make the file more self-contained, and to fix compilation breakage after 28507a415a9b1e.

* glib-compat: fix problems with not-quite glib 2.22Cornelia Huck2015-04-021-1/+3
| | | | | | | | | | | | | | Commit 89b516d8b9444ece8ccabb322a9389587c7a7b83 ("glib: add compatibility interface for g_get_monotonic_time()") aimed at making qemu build with old glib versions. At least SLES11SP3, however, contains a backport of g_get_monotonic_time() while keeping the reported glib version at 2.22. Let's work around this by a strategically placed #define.

* glib: add compatibility interface for g_get_monotonic_time()Stefan Hajnoczi2014-10-151-0/+19
| | | | | | | | | | | | | | | | | This patch fixes compilation errors when building against glib <2.28.0 due to the missing g_get_monotonic_time() function. The compilation error in tests/libqos/virtio.c was introduced in commit 70556264a89a268efba1d7e8e341adcdd7881eb4 ("libqos: use microseconds instead of iterations for virtio timeout"). Add a simple g_get_monotonic_time() implementation to glib-compat.h based on code from vhost-user-test.c.

* glib-compat.h: add new thread API emulation on top of pre-2.31 APIMichael Tokarev2014-06-101-0/+119
| | | | | | | | | | | | | | | | | | | | | | | Thread API changed in glib-2.31 significantly. Before that version, conditionals and mutexes were only allocated dynamically, using _new()/_free() interface. in 2.31 and up, they're allocated statically as regular variables, and old interface is deprecated. (Note: glib docs says the new interface is available since version 2.32, but it was actually introduced in version 2.31). Create the new interface using old primitives, by providing non-opaque definitions of the base types (GCond and GMutex) using GOnces. Replace #ifdeffery around GCond and GMutex in trace/simple.c and coroutine-gthread.c too because it does not work anymore with the new glib-compat.h.

* glib: fix g_poll early timeout on windowsSangho Park2014-05-091-1/+8
| | | | | | | | | | | | | | | | | | | | | | | g_poll has a problem on Windows when using timeouts < 10ms, in glib/gpoll.c: /* If not, and we have a significant timeout, poll again with * timeout then. Note that this will return indication for only * one event, or only for messages. We ignore timeouts less than * ten milliseconds as they are mostly pointless on Windows, the * MsgWaitForMultipleObjectsEx() call will timeout right away * anyway. */ if (retval == 0 && (timeout == INFINITE || timeout >= 10)) retval = poll_rest (poll_msgs, handles, nhandles, fds, nfds, timeout); so whenever g_poll is called with timeout < 10ms it does a quick poll instead of wait, this causes significant performance degradation of QEMU, thus we should use WaitForMultipleObjectsEx directly Signed-off-by: Stanislav Vorobiov <s.vorobiov@samsung.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
