When I integrate my driver against FreeBSD-7 current, I will add some "#if"
statements for those issues. Until further:
In /sys/dev/usb/usb_port.h, use the following:
/* preliminary fix for a bug in msleep on FreeBSD,
* which cannot sleep with Giant:
*/
#undef msleep
#define msleep(i,m,p,w,t) _sleep(i,(((m) == &Giant) ? \
NULL : &(m)->mtx_object),p,w,t)
After this patch you have to insert a NULL argument, to all bus_setup_intr()
functions you find in the files /sys/dev/usb/*pci.c like shown below ?
error = bus_setup_intr(dev, sc->sc_irq_res, INTR_TYPE_TTY,
- si_intr, sc, &ih);
+ NULL, si_intr, sc, &ih);
Hope that is not too much patching.
