> Does accelx by any chance use MAP_PRIVATE?
Bingo!
Between David's comment here and John's own comment in the latest
vm_mmap.c he sent out which says:
* On device mmaps we default to map shared -- makes the most
* sense in this case. Does MAP_PRIVATE even make sense on
* devices mmaps???
I made the following change:
if ((type == OBJT_DEVICE)) {
if (flags & (MAP_PRIVATE|MAP_SHARED) == 0)
flags |= MAP_SHARED;
else if (flags & MAP_PRIVATE)
flags &= ~MAP_PRIVATE;
}
Which turns MAP_PRIVATE *off* for device objects. My Xaccel 1.2 now
works perfectly! Yay!
