i use the total size to figure out where to kick a texture out.
without the right numbers it could end up returning 0 and that would be
bad
since my g200 has no space on the card at all.
It starts up fine but seems to only have a couple of Mb of

it only uploads into card space, this is slower then into agp space.

i have
Section "Device"
Identifier "g200"
Driver "mga"
Option "AGPSize" "32"
EndSection
and get
(II) MGA(0): [agp] 32768 kB allocated with handle 0xd1041000
im currently running with this pice of code..
static int mgaChooseTexHeap( mgaContextPtr mmesa, mgaTextureObjectPtr t
)
{
int freeagp, freecard;
int fitincard, fitinagp;
int totalcard, totalagp;
TMemBlock *b;
totalcard = totalagp = fitincard = fitinagp = freeagp = freecard = 0;
b = mmesa->texHeap[0];
while(b)
{
totalcard += b->size;
if(b->free)
{
if(t->totalSize <= b->size)fitincard = 1;
}
b = b->next;
}
b = mmesa->texHeap[1];
while(b)
{
totalagp += b->size;
if(b->free)
{
if(t->totalSize <= b->size)fitinagp = 1;
}
b = b->next;
}
if(fitincard)return 0;
if(fitinagp)return 1;
if(totalcard && totalagp)
{
int ages;
int ratio = (totalcard > totalagp) ? totalcard / totalagp :
totalagp / totalcard;
ages = mmesa->sarea->texAge[0] + mmesa->sarea->texAge[1];
if( (ages % ratio) == 0)
{
fprintf(stderr,"goes into heap %d\n", totalcard > totalagp ? 1 :
0);
return totalcard > totalagp ? 1 : 0;
}
else
{
fprintf(stderr,"goes into heap %d\n", totalcard > totalagp ? 0 :
1);
return totalcard > totalagp ? 0 : 1;
}
}
fprintf(stderr, "goes into heap %d\n", totalagp ? 1 : 0);
if(totalagp) return 1;
return 0;
}
using the sarea ages is really wishfull thinking but it should work to
select the smaller memory space from time to time.
