Subject: [Qemu-devel] qxl: pthread_yield on QXL_IO_NOTIFY_OOM
Date: Tue, 20 Sep 2011 16:27:57 +0200 [thread overview]
Message-ID: <4E78A2ED.50401@siemens.com> (raw)
Hi Gerd,
can you (or anyone familiar with those bits) comment on pthread_yield()
in ioport_write() of hw/qxl.c? Which threads are supposed to run this
way? Can't this relation be expressed explicitly? If not, can we use a
sleep here (how long?)?
The background is that yielding easily breaks into pieces when leaving
the SCHED_OTHER space (what we are working on).
