It happens here:
res = resource_list_alloc(rl, bus, dev, type, ®, start, end, count,
prefetch ? RF_PREFETCHABLE : 0);
if (res == NULL) {
/*
* If the allocation fails, clear the BAR and delete
* the resource list entry to force
* pci_alloc_resource() to allocate resources from the
* parent.
*/
resource_list_delete(rl, type, reg);
printf("resource_list_alloc() failed\n");
start = 0;
The printf() I added there triggers, and this resets "start" to 0.
Where to proceed now?
