[Mesa3d-dev] share one render buffer within Multithreading multiple contexts in intel driver
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,

The EXT version uses glProvokingVertexEXT, and the ARB > version uses glProvokingVertex. The later doesn't seem to exist in Mesa. Fixed. Guess I was in a hurry and missed the rest. -Brian -- Come build with us! The BlackBerry® Developer Conference in SF, CA is the only developer event you need to attend this year.
