Hello,
I reviewed intel driver in Mesa7.2 and found there seems a problem in
======================================================
intel_region_release(struct intel_region **region)
{
if (!*region)
return;
DBG("%s %d\n", __FUNCTION__, (*region)->refcount - 1);
ASSERT((*region)->refcount > 0);
(*region)->refcount--;
if ((*region)->refcount == 0) {
assert((*region)->map_refcount == 0);
if ((*region)->pbo)
(*region)->pbo->region = NULL;
(*region)->pbo = NULL;
dri_bo_unreference((*region)->buffer);
free(*region);
}
*region = NULL;
}
==========================================
If there are two contexts made current on this region of rb, after
"(*region)->refcount--;" is it possible refcount still be larger than "0", and
it will not be free then leaked?
thanks,
