please check if attached one is more clear.
make max and bottom is only related to _MEM and not default one.
- if (!(res->flags & IORESOURCE_MEM_64))
- max = PCIBIOS_MAX_MEM_32;
+ if (res->flags & IORESOURCE_MEM) {
+ if (!(res->flags & IORESOURCE_MEM_64))
+ max = PCIBIOS_MAX_MEM_32;
+ else if (PCIBIOS_MAX_MEM_32 != -1)
+ bottom = (resource_size_t)(1ULL<<32);
+ }
will still not affect to other arches.
Thanks
