Comment # 25
on bug 110781
from Richard Thier
In the assert problem this is the domain and flag meanings in case of only my
hack is in place:
domain(6) == RADEON_DOMAIN_GTT(2) | RADEON_DOMAIN_VRAM(4)
flags(1) == RADEON_FLAG_GTT_WC (1 << 0)
So I get -1 even if I "outcomment" this check in radeon_get_heap_index(..):
/* Resources with interprocess sharing don't use any winsys allocators.
if (!(flags & RADEON_FLAG_NO_INTERPROCESS_SHARING))
return -1;*/
There is a switch statement in this function where they switch based on the
domain parameter:
switch (domain) {
case RADEON_DOMAIN_VRAM:
...
case RADEON_DOMAIN_GTT:
...
default:
break;
}
return -1;
I suspect we return -1 here because we go into the "default" case. I think that
is right because domain is: 6 == 2 | 4 == GTT+VRAM at the same time.
Maybe once it was meaningful to have both GTT (is that GART?) and VRAM at the
same time being or-ed together but not anymore?
I will try to add a hack to make the domain always just VRAM to see what
happens... I know that is bad, but just for the analysis.
