We are carrying a big burden on our firmware to accommodate 32 bit non-prefetchable memory for supporting all BAR types. Endpoint drivers usually try to allocate both a 64 bit and a 32 bit BAR address for different platforms but they don't usually need both of them. I think the behavior changes from card to card. I'm looking for a way to get rid of 32 bit BAR addresses and support 64 bit BAR addresses only. I want to see the current state of the kernel. Do we know if all resources need to be assigned before a driver can become functional. I have seen some patches to relax this but I don't know the current status. -- Sinan Kaya Qualcomm Datacenter Technologies, Inc. as an affiliate of Qualcomm Technologies, Inc.
