Re: [pci] difference between read and write

[world_wang@msn.com]

I am confused of some comment in the source code.
For example:
// because of transaction ordering, PCI Master must not start read untill 
all writes are done 

Could you tell me in detail what the transaction ordering is ?
I think maybe it is the relationship between read request,read 
completion,write request and write completion.But I am still confused
with it.
thanks for any help.
