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). Jan -- Siemens AG, Corporate Technology, CT T DE IT 1 Corporate Competence Center Embedded Linux
